Flavone is a natural product found in Grindelia hirsutula, Asphodeline damascena, and other organisms with data available. Quercetin is a flavonoid that forms the "backbone" for many other flavonoids, including the citrus flavonoids rutin, hesperidin, naringin and tangeritin. In studies, quercetin is found to be the most active of the flavonoids, and many medicinal plants owe much of their activity to their high quercetin content. Quercetin has demonstrated significant anti-inflammatory activity because of direct inhibition of several initial processes of inflammation. For example, it inhibits both the manufacture and release of histamine and other allergic/inflammatory mediators. In addition, it exerts potent antioxidant activity and vitamin C-sparing action. Flavone is an endogenous metabolite. Flavone is an endogenous metabolite.
Alliin
Alliin /ˈæli.ɪn/ is a sulfoxide that is a natural constituent of fresh garlic.[1] It is a derivative of the amino acid cysteine. When fresh garlic is chopped or crushed, the enzyme alliinase converts alliin into allicin, which is responsible for the aroma of fresh garlic. Allicin and other thiosulfinates in garlic are unstable and form a number of other compounds, such as diallyl sulfide (DAS), diallyl disulfide (DADS) and diallyl trisulfide (DAT), dithiins and ajoene.[2] Garlic powder is not a source of alliin, nor is fresh garlic upon maceration, since the enzymatic conversion to allicin takes place in the order of seconds. Alliin was the first natural product found to have both carbon- and sulfur-centered stereochemistry.[3] Constituent of garlic oil (Allium sativum), also from ramsons (Allium ursinum). (R)C(S)S-Alliin is found in garden onion, garlic, and onion-family vegetables. (R)C(S)S-Alliin is found in garden onion.

Cytidine
Cytidine is a nucleoside that is composed of the base cytosine linked to the five-carbon sugar D-ribose. Cytidine is a pyrimidine that besides being incorporated into nucleic acids, can serve as a substrate for the salvage pathway of pyrimidine nucleotide synthesis. It is a precursor of cytidine triphosphate (CTP) needed in the phosphatidylcholine (PC) and phosphatidylethanolamine (PE) biosynthetic pathways. These variations probably reflect the species differences in cytidine deaminase, the enzyme that converts cytidine to uridine in the body. The transport of cytidine into the brains extracellular fluid, and then into neurons and glia, are essential prerequisites for cytidine to be utilized in the brain. An efficient mechanism mediating the brain uptake of circulating cytidine has not yet been demonstrated. The biosynthesis of PC, the most abundant phosphatide in the brain, via the Kennedy pathway requires phosphocholine and cytidine triphosphate (CTP), a cytidine nucleotide involved in the rate-limiting step. The enzyme that converts CTP to endogenous CDP-choline (CTP:phosphocholine cytidylyltransferase) is unsaturated at physiological brain CTP levels. APOBEC is a family of enzymes that has been discovered with the ability to deaminate cytidines on RNA or DNA. The human apolipoprotein B mRNA-editing enzyme, catalytic polypeptide-like 3G protein (APOBEC3G, or hA3G), provides cells with an intracellular antiretroviral activity that is associated with the hypermutation of viral DNA through cytidine deamination. Indeed, hA3G belongs to a family of vertebrate proteins that contains one or two copies of a signature sequence motif unique to cytidine deaminases (CTDAs) (PMID: 16769123, 15780864, 16720547).

The herb has an extensive history of use in TCM for the treatment of upper respiratory tract infections and other inflammatory and infectious diseases. Andrographolide is a natural product found in Andrographis paniculata, Ginkgo biloba, and Cymbopogon schoenanthus with data available. Andrographolide is a labdane diterpenoid that is produced by the Andrographis paniculata plant, which has a broad range of therapeutic applications including anti-inflammatory and anti-platelet aggregation activities and potential antineoplastic properties. Since andrographolide has multiple therapeutic activities there are several proposed mechanisms of action for this agent. The anti-inflammatory effects of this agent appear to be related to the inhibition of nitric oxide (NO) production by macrophages. This agent may activate the NO/cyclic GMP pathway and inhibit both the phospholipase C gamma 2 (PLC gamma2)/protein kinase C (PKC) and PI3K/AKT-MAPK signaling pathways in activated platelets to inhibit platelet aggregation. In activated platelets, these three signaling pathways are downstream of integrin activation mediated by collagen binding and influence the association of fibrinogen with its receptors. Additionally, andrographolide may exert its anti-cancer activity through the induction of cell cycle arrest at G0/G1 phase and the stimulation of lymphocyte proliferation and activation. These processes could result in decreased proliferation of and increased immunocytotoxicity against tumor cells.

Mimosine
Mimosine is only found in individuals that have used or taken this drug. It is an antineoplastic alanine-substituted pyridine derivative isolated from Leucena glauca. [PubChem]Mimosine causes inhibition of DNA replication, changes in the progression of the cells in the cell cycle, and apoptosis. Mimosine appears to introduce breaks into DNA. Mimosine is an iron/zinc chelator. Iron depletion induces DNA double-strand breaks in treated cells, and activates a DNA damage response that results in focal phosphorylation of histones. This leads to inhibition of DNA replication and/or DNA elongation. Some studies indicate that mimosine prevents the initiation of DNA replication, whereas other studies indicate that mimosine disrupts elongation of the replication fork by impairing deoxyribonucleotide synthesis by inhibiting the activity of the iron-dependent enzyme ribonucleotide reductase and the transcription of the cytoplasmic serine hydroxymethyltransferase gene (SHMT). Inhibition of serine hydroxymethyltransferase is moderated by a zinc responsive unit located in front of the SHMT gene.

Aconitate [cis or trans]
cis-Aconitic acid is an intermediate in the tricarboxylic acid cycle produced by the dehydration of citric acid. The enzyme aconitase (aconitate hydratase; EC 4.2.1.3) catalyses the stereo-specific isomerization of citrate to isocitrate via cis-aconitate in the tricarboxylic acid cycle. Present in apple fruits, maple syrup and passion fruit juice cis-Aconitic acid, also known as (Z)-aconitic acid, plays several important biological roles: Intermediate in the Citric Acid Cycle: cis-Aconitic acid is an intermediate in the tricarboxylic acid (TCA) cycle, also known as the Krebs cycle or citric acid cycle. It is formed from citrate by the enzyme aconitase and is rapidly converted into isocitrate, another key intermediate in the cycle. The TCA cycle is central to cellular respiration, generating energy-rich molecules like NADH and FADH2. Regulation of Aconitase Activity: The conversion of citrate to cis-aconitate and then to isocitrate by aconitase is an important regulatory step in the TCA cycle. This conversion helps in maintaining the balance of the cycle and is influenced by factors like the energy status of the cell. Role in Cholesterol Synthesis: cis-Aconitic acid is also involved in the synthesis of cholesterol. It serves as a precursor for the synthesis of mevalonate, a key intermediate in the cholesterol biosynthesis pathway. Potential Involvement in Disease: Altered metabolism or accumulation of cis-aconitic acid has been associated with certain diseases, including neurodegenerative disorders and cancer. Its role in these conditions is an area of ongoing research. Plant Growth and Development: In plants, cis-aconitic acid has been found to play a role in growth and development, including seed germination and leaf senescence. In summary, cis-aconitic acid is a crucial intermediate in the TCA cycle, impacting energy production and various metabolic pathways in cells. Its role extends to cholesterol synthesis and potentially to various disease processes, highlighting its importance in cellular metabolism and physiology. cis-Aconitic acid. CAS Common Chemistry.

Prostaglandin A1
Prostaglandin A1 (PGA1, a prostaglandin characterized by a cyclopentenone structure) has a fundamental structure common to punaglandin and clavulone, the antitumor eicosanoids discovered in marine organisms such as corals. It is well established that PGA1, which exert potent antiviral activity in several DNA and RNA virus models, induce heat shock protein (hsp)70 syntheses through cycloheximide sensitive activation of heat shock transcription factor. Antitumor prostaglandins are actively incorporated through cell membrane and control gene expression. P53 (protein 53, is a transcription factor that regulates the cell cycle and functions as a tumor suppressor) independent expression of p21 (also known as cyclin-dependent kinase inhibitor 1A or CDKN1A, is a human gene on chromosome 6 (location 6p21.2), that encodes a cyclin-dependent kinase) and gadd 45 (growth arrest and DNA-damage-inducible, alpha 45, a major breast cancer (BRCA1) target is the DNA damage-responsive gene GADD45) activation of peroxisome proliferative activated receptor gamma (PPARgamma) are involved in antitumor mechanism of these prostaglandins. At the low concentration, these prostaglandins exhibit physiological or pathological activity such as osteoblast calcification, promotion of colon cancer cell proliferation. One of the mechanisms of anti-cancer activity of prostaglandins, has been believed to be that these prostaglandins might have p53 like effect in cells lacking p53. (PMID: 7988663, 11104898)Prostaglandins are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signalling pathways.

Sulindac
Sulindac is a nonsteroidal anti-inflammatory agent (NSAIA) of the arylalkanoic acid class that is marketed in the U.S. by Merck as Clinoril. Like other NSAIAs, it may be used in the treatment of acute or chronic inflammatory conditions. Sulindac is a prodrug, derived from sulfinylindene, that is converted in vivo to an active sulfide compound by liver enzymes. The sulfide metabolite then undergoes enterohepatic circulation; it is excreted in the bile and then reabsorbed from the intestine. This is thought to help maintain constant blood levels with reduced gastrointestinal side effects. Some studies have shown sulindac to be relatively less irritating to the stomach than other NSAIAs except for drugs of the cyclooxygenase-2 (COX-2) inhibitor class. The exact mechanism of its NSAIA properties is unknown, but it is thought to act on enzymes COX-1 and COX-2, inhibiting prostaglandin synthesis.

N2-acetyllysine
N-alpha-Acetyl-L-lysine also known as Nalpha-Acetyllysine, belongs to the class of organic compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. N-alpha-Acetyl-L-lysine can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-alpha-Acetyl-L-lysine is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-lysine. Unlike L-lysine, acetylated lysine derivatives such as N-alpha-Acetyl-L-lysine are zwitterionic compounds. These are molecules that contains an equal number of positively- and negatively-charged functional groups. N-alpha-Acetyl-L-lysine is found naturally in eukaryotes ranging from yeast to plants to humans. N-acetyl amino acids can be produced either via direct synthesis of specific N-acetyltransferases or via the proteolytic degradation of N-acetylated proteins by specific hydrolases. N-terminal acetylation of proteins is a widespread and highly conserved process in eukaryotes that is involved in protection and stability of proteins (PMID: 16465618). About 85\\\% of all human proteins and 68\\\% of all yeast proteins are acetylated at their N-terminus (PMID: 21750686). Several proteins from prokaryotes and archaea are also modified by N-terminal acetylation. The majority of eukaryotic N-terminal-acetylation reactions occur through N-acetyltransferase enzymes or NAT’s (PMID: 30054468). These enzymes consist of three main oligomeric complexes NatA, NatB, and NatC, which are composed of at least a unique catalytic subunit and one unique ribosomal anchor. The substrate specificities of different NAT enzymes are mainly determined by the identities of the first two N-terminal residues of the target protein. The human NatA complex co-translationally acetylates N-termini that bear a small amino acid (A, S, T, C, and occasionally V and G) (PMID: 30054468). NatA also exists in a monomeric state and can post-translationally acetylate acidic N-termini residues (D-, E-). NatB and NatC acetylate N-terminal methionine with further specificity determined by the identity of the second amino acid. N-acetylated amino acids, such as N-alpha-Acetyl-L-lysine can be released by an N-acylpeptide hydrolase from peptides generated by proteolytic degradation (PMID: 16465618). In addition to the NAT enzymes and protein-based acetylation, N-acetylation of free lysine can also occur. In particular, N-alpha-Acetyl-L-lysine can be biosynthesized from L-lysine and acetyl-CoA via the enzyme known as Lysine N-acetyltransferase. Individuals with hyperlysinaemia due to L-lysine alpha-ketoglutarate reductase deficiency will excrete high levels of N-alpha-Acetyl-L-lysine in their urine (PMID: 116084). L-lysine alpha-ketoglutarate reductase deficiency, if untreated, can lead to neurological and behavioral deficits (PMID: 116084). Many N-acetylamino acids are classified as uremic toxins if present in high abundance in the serum or plasma (PMID: 26317986; PMID: 20613759). Uremic toxins are a diverse group of endogenously produced molecules that, if not properly cleared or eliminated by the kidneys, can cause kidney damage, cardiovascular disease and neurological deficits (PMID: 18287557).

isopentenyl adenosine
Riboprine, also known as isopentenyladenosine or ipa, is a member of the class of compounds known as purine nucleosides. Purine nucleosides are compounds comprising a purine base attached to a ribosyl or deoxyribosyl moiety. Riboprine is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Riboprine can be found in a number of food items such as peppermint, chinese mustard, custard apple, and green bean, which makes riboprine a potential biomarker for the consumption of these food products.

Prostaglandin J2
Prostaglandin J2 (PGJ2) is an endogenous product of inflammation in humans. It induces neuronal death and the accumulation of ubiquitinated proteins into distinct aggregates. It may play a role in neurodegenerative disorders inducing a chain of events that culminates in neuronal cell death. An altered expression of enzymes in PGJ2 synthesis may represent a novel pathogenic mechanism in human obesity. The peroxisome proliferator-activated receptor gamma (PPARγ) has a fundamental role in glucose homeostasis and adipocyte differentiation. Besides linoleate, linolenate and arachidonate, the most notable PPAR ligand is 15-deoxy-delta12-14-prostaglandin J2, a natural derivative of prostaglandin D2 and PGJ2. It is therefore plausible that the production of 15d-PGJ2 within adipose tissue may act as an endogenous mediator of adipocyte differentiation. PGJ2 disrupts the cytoskeleton in neuronal cells. This cyclopentenone prostaglandin triggered endoplasmic reticulum (ER) collapse and the redistribution of ER proteins, such as calnexin and catechol-O-methyltransferase, into a large centrosomal aggregate containing ubiquitinated proteins and alpha-synuclein. The PGJ2-dependent cytoskeletal rearrangement paralleled the development of the large centrosomal aggregate. Supporting a mechanism by which, upon PGJ2 treatment, cytoskeleton/ER collapse coincides with the relocation of ER proteins, other potentially neighboring proteins, and ubiquitinated proteins into centrosomal aggregates. Development of these large perinuclear aggregates is associated with disruption of the microtubule/ER network. This aberrant protein deposition, triggered by a product of inflammation, may be common to other compounds that disrupt microtubules and induce protein aggregation, such as MPP+ and rotenone, found to be associated with neurodegeneration. Many neurodegenerative disorders, such as Parkinson disease, exhibit inclusion bodies containing ubiquitinated proteins. Concentrations of PGJ2 in biofluids have not been established, since this prostaglandin is further metabolized into delta12-PGJ2, and 15-deoxy-delta12,14-PGJ2. (PMID: 16737963, 16842938, 16774923)Prostaglandins are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs).

Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signalling pathways. Prostaglandin J2 (PGJ2) is an endogenous product of inflammation in humans.

Delta-12-Prostaglandin J2
Delta-12-Prostaglandin J2 (d12-PGJ2) is the ultimate metabolite of Prostaglandin D2 (PGD2). PGD2 is an unstable molecule and undergoes dehydration to form PGJ2 in aqueous solution, and is then converted to d12-PGJ2, in the presence of serum albumin or plasma. d12-PGJ2 forms a conjugate with the thiol of glutathione (GSH) and GSH suppresses the d12-PGJ2-induced HSP synthesis and subsequent inhibition of cell growth (HSPs are a set of proteins synthesized in response to heat shock or to other environmental stresses). d12-PGJ2 has been shown to stimulate alkaline phosphatase activity and calcification of human osteoblastic cells, the potency of the PGs being comparable to that of 1-a,25-dihydroxy vitamin D. d12-PGJ2 enhances the type-1 collagen synthesis in human osteoblasts during calcification. Thus, d12-PGJ2 modulates osteogenesis through induction of the syntheses of multiple proteins related to mineralization. Considering that PGD2 is a major arachidonate metabolite in bone marrow, d12-PGJ2, may be physiologically involved in the modulation of osteogenesis. d12-PGJ2 induces heme oxygenase, HO-l. Heme oxygenase is a key enzyme in heme catabolism, oxidatively clearing heme to yield biliverdin, iron and carbon monoxide. The biological function of this enzyme is the conversion of potentially toxic heme to bile and the recovery of the iron. Furthermore, carbon monoxide produced on the enzymatic degradation of heme has been suggested to function as a neural messenger. Two isozymes of heme oxygenase, HO-l and HO-2, have been identified. HO-2 is constitutively expressed, while HO-l is drastically induced in response to a variety of stresses, including heavy metals, heat shock and UV irradiation.

Cidofovir
Cidofovir is only found in individuals that have used or taken this drug. It is an injectable antiviral medication for the treatment of cytomegalovirus (CMV) retinitis in patients with AIDS. It suppresses CMV replication by selective inhibition of viral DNA synthesis. [Wikipedia]Cidofovir acts through the selective inhibition of viral DNA polymerase.Biochemical data support selective inhibition of CMV DNA polymerase by cidofovir diphosphate, the active intracellular metabolite of cidofovir. Cidofovir diphosphate inhibits herpesvirus polymerases at concentrations that are 8- to 600-fold lower than those needed to inhibit human cellular DNA polymerase alpha, beta, and gamma(1,2,3). Incorporation of cidofovir into the growing viral DNA chain results in reductions in the rate of viral DNA synthesis.

Beryllium
Beryllium is a light-weight metallic element, which was first recognized as a lung hazard in Europe in the 1930s, shortly after its first production in modern industry. People exposed to beryllium compounds are at increased risk of developing beryllium sensitization and chronic beryllium disease (CBD). The chronic lung disease was first described among workers exposed to beryllium-containing materials used in the manufacture of fluorescent lamps. In primary production of beryllium metal, which was used in nuclear weapons components, physicians recognized severe dermatitis, reversible pneumonitis, and chronic granulomatous lung disease. Physiologically, this metal/element exists as an ion in the body. It is now recognized that the physicochemical properties of beryllium compounds may account for the differing clinical presentations in different industries. In primary production of beryllium metal, soluble salts are present and cause rashes in approximately one fourth of exposed workers and reversible acute pneumonitis in a smaller portion of the workforce. After heavy inhalation exposures, radiographic abnormalities evolve at approximately three weeks; resolution of symptoms and radiologic abnormalities away from exposure occur only after months, but symptoms recur immediately upon reexposure. The granulomatous nature of chronic beryllium disease is now known to be caused by cell-mediated sensitization to beryllium. Chronic beryllium disease (CBD) is a granulomatous lung disorder characterized by the accumulation of beryllium-specific CD4(+) T cells. Depending on genetic susceptibility and the nature of the exposure, CBD occurs in up to 20\\% of exposed workers. Genetic susceptibility has been associated with particular HLA-DP alleles, especially those possessing a negatively charged glutamic acid residue at the 69th position of the beta-chain. The mechanism for this association lies in the ability of these HLA-DP molecules to bind and present beryllium to pathogenic CD4(+) T cells. Large numbers of effector memory, beryllium-specific CD4(+) T cells are recruited to the lung of these subjects and secrete Th1-type cytokines upon beryllium recognition. The presence of circulating beryllium-specific CD4(+) T cells directly correlates with the severity of lymphocytic alveolitis. Since 1987, this biomarker of sensitization has enabled medical surveillance of beryllium-exposed workforces. Beryllium lymphocyte proliferation tests have been used to screen workers to detect sensitization, to characterize epidemiologically workplace risks for beryllium sensitization, and to evaluate the effectiveness of interventions intended to prevent sensitization. The most compelling real-world example of genetic testing for susceptibility to a workplace exposure involves those industries that process or fabricate beryllium. Under reasonable assumptions, the longitudinal positive predictive value of the HLA-DPB1-Glu69 marker of susceptibility to beryllium disease is 12\\%. Interpretive challenges further limit the utility of the test and may inadvertently suggest a false sense of safety among workers. Reduction in inhalation exposure to beryllium has not resulted in a concomitant reduction in the occurrence of beryllium sensitization or CBD, suggesting that continued prevalence may be due, in part, to unchecked skin exposure to beryllium-containing particles.

Flavone
Quercetin is a flavonoid that forms the "backbone" for many other flavonoids, including the citrus flavonoids rutin, hesperidin, naringin and tangeritin. In studies, quercetin is found to be the most active of the flavonoids, and many medicinal plants owe much of their activity to their high quercetin content. Quercetin has demonstrated significant anti-inflammatory activity because of direct inhibition of several initial processes of inflammation. For example, it inhibits both the manufacture and release of histamine and other allergic/inflammatory mediators. In addition, it exerts potent antioxidant activity and vitamin C-sparing action. -- Wikipedia.

Arabinofuranosylcytosine (Ara-C), also known as cytarabine, is a chemotherapeutic agent that is widely used in the treatment of various types of cancer, particularly hematological malignancies such as acute myeloid leukemia (AML) and chronic myeloid leukemia (CML). The biological functions of Ara-C are primarily related to its antineoplastic properties, which are derived from its mechanism of action within the cell. Here is a detailed description of its biological functions: 1. **Inhibition of DNA Synthesis**: Ara-C functions as a nucleoside analog, which means it resembles the natural building blocks of DNA. Once inside the cell, Ara-C is converted to its active metabolite, araCTP (arabinofuranosylcytosine triphosphate). AraCTP competes with the natural deoxycytidine triphosphate (dCTP) for incorporation into the growing DNA chain during the S phase of the cell cycle. Because Ara-C lacks a 3'-hydroxyl group, its incorporation into DNA leads to chain termination, effectively stopping DNA synthesis. 2. **Cell Cycle Specificity**: Ara-C is most effective against cells that are actively dividing. Since it targets cells in the S phase of the cell cycle, it is particularly harmful to rapidly dividing cancer cells, which often spend a significant portion of their cycle in this phase. 3. **Inhibition of DNA Repair**: Beyond its direct effect on DNA synthesis, Ara-C can also interfere with DNA repair mechanisms. This is because the incorporation of Ara-C into DNA can cause mispairing and induce DNA damage, which the cell may be unable to repair properly. 4. **Cell Death Induction**: The inhibition of DNA synthesis and the induction of DNA damage can lead to cell death through apoptosis or necrosis. Cells that cannot replicate their DNA or repair the damage caused by Ara-C activation are programmed to die, which is a desirable outcome in the context of cancer treatment. 5. **Immune System Modulation**: In some cases, Ara-C can also modulate the immune system, although this is not its primary function. It can affect the function and proliferation of immune cells, which can have implications for both its therapeutic effects and side effects. 6. **Enzymatic Conversion**: Ara-C must be activated within the cell by the enzyme deoxycytidine kinase (dCK), which phosphorylates it to Ara-CMP (monophosphate), then to Ara-CDP (diphosphate), and finally to Ara-CTP. The efficiency of this conversion can vary between different types of cancer cells and normal cells, contributing to the selectivity of Ara-C's action. 7. **Cross-Linking Potential**: Although less common, Ara-C can also form cross-links with DNA, further complicating DNA structure and function, which can contribute to its cytotoxic effects. The biological functions of Ara-C are complex and can vary depending on the dose, the specific cancer type, and the individual patient's metabolism. Its use is carefully monitored in clinical settings due to its potential for significant side effects, including myelosuppression (decreased production of blood cells), gastrointestinal toxicity, and central nervous system toxicity.
