Cinobufagin

[(1R,2S,4R,5R,6R,7R,10S,11S,14S,16R)-14-hydroxy-7,11-dimethyl-6-(6-oxopyran-3-yl)-3-oxapentacyclo[8.8.0.02,4.02,7.011,16]octadecan-5-yl] acetate

C26H34O6 (442.2355)


Cinobufagin is a steroid lactone. It is functionally related to a bufanolide. Cinobufagin is a natural product found in Bufo gargarizans, Phrynoidis asper, and other organisms with data available. Cinobufagin is a bufadienolide compound extracted from the dried venom secreted by the parotid glands of toads and one of the glycosides in the traditional Chinese medicine ChanSu, with potential antineoplastic activity. Although the mechanism of action of cinobufagin is still under investigation, it has been found to suppress cancer cell proliferation and cause apoptosis in cancer cells via a sequence of apoptotic modulators that include mitochondrial Bax and cytosolic chromosome c, and caspases 3, 8, and 9. Possible upstream mediators of cinobufagin-induced apoptosis include Fas and p53.

Levetiracetam

alpha Ethyl 2 oxo 1 pyrrolidineacetamide

C8H14N2O2 (170.1055)


Levetiracetam is an anticonvulsant medication used to treat epilepsy. Levetiracetam may selectively prevent hypersynchronization of epileptiform burst firing and propagation of seizure activity. Levetiracetam binds to the synaptic vesicle protein SV2A, which is thought to be involved in the regulation of vesicle exocytosis. Although the molecular significance of levetiracetam binding to synaptic vesicle protein SV2A is not understood, levetiracetam and related analogs showed a rank order of affinity for SV2A which correlated with the potency of their antiseizure activity in audiogenic seizure-prone mice.

Vigabatrin

Acid, gamma-vinyl-gamma-aminobutyric

C6H11NO2 (129.079)


Vigabatrin is only found in individuals that have used or taken this drug. It is an analogue of gamma-aminobutyric acid. It is an irreversible inhibitor of 4-aminobutyrate transaminase, the enzyme responsible for the catabolism of gamma-aminobutyric acid. (From Martindale The Extra Pharmacopoeia, 31st ed)It is believed that vigabatrin increases brain concentrations of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter in the CNS, by irreversibly inhibiting enzymes that catabolize GABA (gamma-aminobutyric acid transaminase GABA-T) or block the reuptake of GABA into glia and nerve endings. Vigabatrin may also work by suppressing repetitive neuronal firing through inhibition of voltage-sensitive sodium channels.

Diethanolamine, often abbreviated as DEA, is an organic chemical compound which is both a secondary amine and a dialcohol. A dialcohol has two hydroxyl groups in its molecule. Like other amines, diethanolamine acts as a weak base. Diethanolamine is widely used in the preparation of diethanolamides and diethanolamine salts of long-chain fatty acids that are formulated into soaps and surfactants used in liquid laundry and dishwashing detergents, cosmetics, shampoos, and hair conditioners. Diethanolamine is also used in textile processing, in industrial gas purification to remove acid gases, as an anticorrosion agent in metalworking fluids, and in preparations of agricultural chemicals. Aqueous diethanolamine solutions are used as solvents for numerous drugs that are administered intravenously.

Topotecan

(19S)-8-[(dimethylamino)methyl]-19-ethyl-7,19-dihydroxy-17-oxa-3,13-diazapentacyclo[11.8.0.0^{2,11}.0^{4,9}.0^{15,20}]henicosa-1(21),2(11),3,5,7,9,15(20)-heptaene-14,18-dione

C23H23N3O5 (421.1638)


Topotecan is only found in individuals that have used or taken this drug. It is an antineoplastic agent used to treat ovarian cancer. It works by inhibiting DNA topoisomerases, type I. [PubChem]Topotecan has the same mechanism of action as irinotecan and is believed to exert its cytotoxic effects during the S-phase of DNA synthesis. Topoisomerase I relieves torsional strain in DNA by inducing reversible single strand breaks. Topotecan binds to the topoisomerase I-DNA complex and prevents religation of these single strand breaks. This ternary complex interferes with the moving replication fork, which leads to the induction of replication arrest and lethal double-stranded breaks in DNA. As mammalian cells cannot efficiently repair these double strand breaks, the formation of this ternary complex eventually leads to apoptosis (programmed cell death).Topotecan mimics a DNA base pair and binds at the site of DNA cleavage by intercalating between the upstream (−1) and downstream (+1) base pairs. Intercalation displaces the downstream DNA, thus preventing religation of the cleaved strand. By specifically binding to the enzyme–substrate complex, Topotecan acts as an uncompetitive inhibitor. Topotecan is a pyranoindolizinoquinoline used as an antineoplastic agent. It is a derivative of camptothecin and works by binding to the topoisomerase I-DNA complex and preventing religation of these 328 single strand breaks. It has a role as an EC 5.99.1.2 (DNA topoisomerase) inhibitor and an antineoplastic agent. An antineoplastic agent used to treat ovarian cancer. It works by inhibiting DNA topoisomerases, type I. Topotecan is a Topoisomerase Inhibitor. The mechanism of action of topotecan is as a Topoisomerase Inhibitor. Topotecan is a semisynthetic derivative of camptothecin, a cytotoxic, quinoline-based alkaloid extracted from the Asian tree Camptotheca acuminata. Topotecan inhibits topoisomerase I activity by stabilizing the topoisomerase I-DNA covalent complexes during S phase of cell cycle, thereby inhibiting religation of topoisomerase I-mediated single-strand DNA breaks and producing potentially lethal double-strand DNA breaks when encountered by the DNA replication machinery. An antineoplastic agent used to treat ovarian cancer. It works by inhibiting DNA TOPOISOMERASES, TYPE I. See also: Topotecan Hydrochloride (active moiety of).

Ethosuximide

3-Ethyl-3-methyl-2,5-pyrrolidinedione

C7H11NO2 (141.079)


Ethosuximide is only found in individuals that have used or taken this drug. It is an anticonvulsant especially useful in the treatment of absence seizures unaccompanied by other types of seizures. [PubChem]Binds to T-type voltage sensitive calcium channels. Voltage-sensitive calcium channels (VSCC) mediate the entry of calcium ions into excitable cells and are also involved in a variety of calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, gene expression, cell motility, cell division and cell death. The isoform alpha-1G gives rise to T-type calcium currents. T-type calcium channels belong to the "low-voltage activated (LVA)" group and are strongly blocked by mibefradil. A particularity of this type of channels is an opening at quite negative potentials and a voltage-dependent inactivation. T-type channels serve pacemaking functions in both central neurons and cardiac nodal cells and support calcium signaling in secretory cells and vascular smooth muscle. They may also be involved in the modulation of firing patterns of neurons which is important for information processing as well as in cell growth processes.

Levuglandin E2

(5Z,8S,9R,10E,12S)-8-acetyl-9-formyl-12-hydroxyheptadeca-5,10-dienoic acid

C20H32O5 (352.225)


Levuglandin E2 is a levuglandin generated in the cyclooxygenase (COX) pathway. Levuglandins (LGs) and their stereo and structural isomers are extraordinarily reactive γ-ketoaldehydes that are generated by rearrangements of prostanoid endoperoxide intermediates of polyene cyclooxygenation. Their rapid adduction with biological nucleophiles results, inter alia, in pathological modifications of proteins and DNA. It also complicates their detection. Cyclooxygenase-promoted lipid oxidation is a pivotal step in the biosynthesis of an array of physiologically active metabolites. COX fosters a highly regio and stereoselective cyclooxygenation of arachidonic acid (AA) to deliver a single, enantiomerically pure endoperoxide, PGH2, that is a branch point in the biosynthesis of numerous hormone-like mediators of cellular activities. Spontaneous rearrangements of PGH2 were known to generate prostaglandins (PG) PGD2 and PGE2. (PMID: 15752459) [HMDB] Levuglandin E2 is a levuglandin generated in the cyclooxygenase (COX) pathway.
