Piperine
Piperine, also known as fema 2909, belongs to the class of organic compounds known as alkaloids and derivatives. These are naturally occurring chemical compounds that contain mostly basic nitrogen atoms. This group also includes some related compounds with neutral and even weakly acidic properties. Also some synthetic compounds of similar structure are attributed to alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and more rarely other elements such as chlorine, bromine, and phosphorus. Piperine is a pepper tasting compound. Piperine is found in the highest concentration within pepper (Piper nigrum) and many other Piper species. Piperine has also been detected, but not quantified, in dills and herbs and spices. Piperine is responsible for the hot taste of pepper. Piperine has been used in trials studying the treatment of Multiple Myeloma and Deglutition Disorders. It is used to impart pungent taste to brandy. Piperine is a N-acylpiperidine that is piperidine substituted by a (1E,3E)-1-(1,3-benzodioxol-5-yl)-5-oxopenta-1,3-dien-5-yl group at the nitrogen atom. It is an alkaloid isolated from the plant Piper nigrum. It has a role as a NF-kappaB inhibitor, a plant metabolite, a food component and a human blood serum metabolite.

Letrozole
Letrozole is a member of triazoles and a nitrile. It has a role as an antineoplastic agent and an EC 1.14.14.14 (aromatase) inhibitor. Letrozole, or CGS 20267, is an oral non-steroidal type II aromatase inhibitor first described in the literature in 1990. It is a third generation aromatase inhibitor like [exemestane] and [anastrozole], meaning it does not significantly affect cortisol, aldosterone, and thyroxine. Letrozole was granted FDA approval on 25 July 1997. Letrozole is an Aromatase Inhibitor. The mechanism of action of letrozole is as an Aromatase Inhibitor. Letrozole is a nonsteroidal inhibitor of aromatase which effectively blocks estrogen synthesis in postmenopausal women and is used as therapy of estrogen receptor positive breast cancer, usually after resection and after failure of tamoxifen. Letrozole has been associated with a low rate of serum enzyme elevations during therapy and rare instances of clinically apparent liver injury. Letrozole is a nonsteroidal inhibitor of estrogen synthesis with antineoplastic activity. As a third-generation aromatase inhibitor, letrozole selectively and reversibly inhibits aromatase, which may result in growth inhibition of estrogen-dependent breast cancer cells. Aromatase, a cytochrome P-450 enzyme localized to the endoplasmic reticulum of the cell and found in many tissues including those of the premenopausal ovary, liver, and breast, catalyzes the aromatization of androstenedione and testosterone into estrone and estradiol, the final step in estrogen biosynthesis. Letrozole (INN, trade name Femara®) is an oral non-steroidal aromatase inhibitor that has been introduced for the adjuvant treatment of hormonally-responsive breast cancer. Estrogens are produced by the conversion of androgens through the activity of the aromatase enzyme. Letrozole blocks production of estrogens in this way by competitive, reversible binding to the heme of its cytochrome P450 unit. The action is specific, and letrozole does not reduce production of mineralo- or corticosteroids. In contrast, the antiestrogenic action of tamoxifen, the major medical therapy prior to the arrival of aromatase inhibitors, is due to its interfering with the estrogen receptor, rather than inhibiting estrogen production. Letrozole is approved by the United States Food and Drug Administration (FDA) for the treatment of local or metastatic breast cancer that is hormone receptor positive or has an unknown receptor status in postmenopausal women. Side effects include signs and symptoms of hypoestrogenism. There is concern that long term use may lead to osteoporosis, which is why prescriptions of Letrozole are often accompanied by prescriptions of osteoporosis-fighting medication such as Fosamax. Letrozole has shown to reduce estrogen levels by 98 percent while raising testosterone levels. The anti-estrogen action of letrozole is preferred by athletes and bodybuilders for use during a steroid cycle to reduce bloating due to excess water retention and prevent the formation of gynecomastia related breast tissue that is a side effect of some anabolic steroids. Usage above 2.5 mg/day is known to potentially temporarily kill sex drive. Above 5mg/day for extended periods may cause kidney problems. Letrozole has also been shown to delay the fusing of the growth plates in adolescents. This may boost the effectiveness of growth hormone, and thus Letrozole is used to treat adolescents and children with short stature. A triazole and benzonitrile derivative that is a selective non-steroidal aromatase inhibitor, similar to ANASTROZOLE. It is used in the treatment of metastatic or locally advanced breast cancer in postmenopausal women. See also: Letrozole; ribociclib succinate (component of).

Morphine
C17H19NO3 (285.13648639999997)
Morphine, also known as (-)-morphine or morphine sulfate, is a member of the class of compounds known as morphinans. Morphinans are polycyclic compounds with a four-ring skeleton with three condensed six-member rings forming a partially hydrogenated phenanthrene moiety, one of which is aromatic while the two others are alicyclic. Morphine is soluble (in water) and a very weakly acidic compound (based on its pKa). Morphine can be synthesized from morphinan. Morphine is also a parent compound for other transformation products, including but not limited to, myrophine, heroin, and codeine. Morphine can be found in a number of food items such as nanking cherry, eggplant, millet, and common hazelnut, which makes morphine a potential biomarker for the consumption of these food products. Morphine can be found primarily in blood and urine, as well as in human kidney and liver tissues. In humans, morphine is involved in several metabolic pathways, some of which include heroin action pathway, morphine metabolism pathway, heroin metabolism pathway, and codeine metabolism pathway. Morphine is a non-carcinogenic (not listed by IARC) potentially toxic compound. Morphine is a drug which is used for the relief and treatment of severe pain. The primary source of morphine is isolation from poppy straw of the opium poppy. In 2013, an estimated 523 000 kg of morphine were produced. About 45 000 kg were used directly for pain, a four-time increase over the last twenty years. Most use for this purpose was in the developed world. About 70\\% of morphine is used to make other opioids such as hydromorphone, oxymorphone, and heroin. It is a Schedule II drug in the United States, Class A in the United Kingdom, and Schedule I in Canada. It is on the World Health Organizations List of Essential Medicines, the most effective and safe medicines needed in a health system. Morphine is sold under many trade names . Primarily hepatic (90\\%), converted to dihydromorphinone and normorphineand is) also converted to morphine-3-glucuronide (M3G) and morphine-6-glucuronide. Virtually all morphine is converted to glucuronide metabolites; only a small fraction (less than 5\\%) of absorbed morphine is demethylated (DrugBank). In the treatment of morphine overdosage, primary attention should be given to the re- establishment of a patent airway and institution of assisted or controlled ventilation. Supportive measures (including oxygen, vasopressors) should be employed in the management of circulatory shock and pulmonary edema accompanying overdose as indicated. Cardiac arrest or arrhythmias may require cardiac massage or defibrillation. The pure opioid antagonists, such as naloxone, are specific antidotes against respiratory depression which results from opioid overdose. Naloxone should be administered intravenously; however, because its duration of action is relatively short, the patient must be carefully monitored until spontaneous respiration is reliably re-established. If the response to naloxone is suboptimal or not sustained, additional naloxone may be administered, as needed, or given by continuous infusion to maintain alertness and respiratory function; however, there is no information available about the cumulative dose of naloxone that may be safely administered (L1712) (T3DB). Morphine is the principal alkaloid in opium and the prototype opiate analgesic and narcotic. In 2017, morphine was the 155th most commonly prescribed medication in the United States, with more than four million prescriptions. Morphine is used primarily to treat both acute and chronic severe pain. Its duration of analgesia is about three to seven hours. A large overdose of morphine can cause asphyxia and death by respiratory depression if the person does not receive medical attention immediately. Morphine is naturally produced by several plants (such as the opium poppy) and animals (PMID: 22578954). Morphine was first isolated between 1803 and 1805 by Friedrich Sertürner. Sertürner originally named the substance morphium after the Greek god of dreams, Morpheus, as it has a tendency to cause sleep. The primary source of morphine is isolation from poppy straw of the opium poppy. Morphine is also endogenously produced by humans. In the mid 2000s it was found morphine can be synthesized by white blood cells (PMID 22578954). CYP2D6, a cytochrome P450 isoenzyme, catalyzes the biosynthesis of morphine from codeine and dopamine from tyramine. The morphine biosynthetic pathway in humans occurs as follows: L-tyrosine -> para-tyramine or L-DOPA -> dopamine -> (S)-norlaudanosoline -> (S)-reticuline -> 1,2-dehydroretinulinium -> (R)-reticuline -> salutaridine -> salutaridinol -> thebaine -> neopinone -> codeinone -> codeine -> morphine. (S)-Norlaudanosoline (also known as tetrahydropapaveroline) which is an important intermediate in the WBC biosynthesis of morphine can also be synthesized from 3,4-dihydroxyphenylacetaldehyde (DOPAL), a metabolite of L-DOPA and dopamine. Morphine has widespread effects in the central nervous system and on smooth muscle (PMID: 4582903). The precise mechanism of the analgesic action of morphine is not fully known. However, specific CNS opiate receptors have been identified and likely play a role in the induction of analgesic effects. Morphine first acts on the mu-opioid receptors. The mechanism of respiratory depression involves a reduction in the responsiveness of the brain stem respiratory centers to increases in carbon dioxide tension and electrical stimulation. It has been shown that morphine binds to and inhibits GABA inhibitory interneurons. These interneurons normally inhibit the descending pain inhibition pathway. So, without the inhibitory signals, pain modulation can proceed downstream. When the dose of morphine is reduced after long-term use, opioid withdrawal symptoms such as drowsiness, vomiting, and constipation may also occur (PMID: 23244430). Morphine is only found in easily detectable quantities in individuals that have used or taken this drug.

Hydromorphone
C17H19NO3 (285.13648639999997)
Hydromorphone is only found in individuals that have used or taken this drug. It is an opioid analgesic derived from morphine and used mainly as an analgesic. It has a shorter duration of action and is more potent than morphine. [PubChem]Hydromorphone is a narcotic analgesic; its principal therapeutic effect is relief of pain. Hydromorphone interacts predominantly with the opioid mu-receptors. These mu-binding sites are discretely distributed in the human brain, with high densities in the posterior amygdala, hypothalamus, thalamus, nucleus caudatus, putamen, and certain cortical areas. They are also found on the terminal axons of primary afferents within laminae I and II (substantia gelatinosa) of the spinal cord and in the spinal nucleus of the trigeminal nerve. In clinical settings, Hydromorphone exerts its principal pharmacological effect on the central nervous system and gastrointestinal tract. Hydromorphone also binds with kappa-receptors which are thought to mediate spinal analgesia, miosis and sedation.

N4-Acetylcytidine is a modified nucleoside. N4-acetylcytidine is an endogenous urinary nucleoside product of the degradation of transfer ribonucleic acid (tRNA); urinary nucleosides are biological markers for patients with colorectal cancer. tRNA has been shown to be excreted in abnormal amounts in the urine of cancer patients. tRNA from neoplastic tissue had a much more rapid turnover rate than the tRNA from the corresponding normal tissue. Evidence indicates that methylation of tRNA occurs only after synthesis of the intact macromolecule. Because there are no specific enzyme systems to incorporate the modified nucleosides into the macromolecular nucleic acid, these nucleosides once released in the process of tRNA turnover cannot be reutilized, nor are they further degraded, but are excreted in urine.

dimethylidenebutanedioylcarnitine
dimethylidenebutanedioylcarnitine is an acylcarnitine. More specifically, it is an dimethylidenebutanedioic acid ester of carnitine. Acylcarnitines were first discovered more than 70 year ago (PMID: 13825279). It is believed that there are more than 1000 types of acylcarnitines in the human body. The general role of acylcarnitines is to transport acyl-groups (organic acids and fatty acids) from the cytoplasm into the mitochondria so that they can be broken down to produce energy. This process is known as beta-oxidation. According to a recent review [Dambrova et al. 2021, Physiological Reviews], acylcarnitines (ACs) can be classified into 9 different categories depending on the type and size of their acyl-group: 1) short-chain ACs; 2) medium-chain ACs; 3) long-chain ACs; 4) very long-chain ACs; 5) hydroxy ACs; 6) branched chain ACs; 7) unsaturated ACs; 8) dicarboxylic ACs and 9) miscellaneous ACs. Short-chain ACs have acyl-groups with two to five carbons (C2-C5), medium-chain ACs have acyl-groups with six to thirteen carbons (C6-C13), long-chain ACs have acyl-groups with fourteen to twenty once carbons (C14-C21) and very long-chain ACs have acyl groups with more than 22 carbons. dimethylidenebutanedioylcarnitine is therefore classified as a medium chain AC. As a medium-chain acylcarnitine dimethylidenebutanedioylcarnitine is somewhat less abundant than short-chain acylcarnitines. These are formed either through esterification with L-carnitine or through the peroxisomal metabolism of longer chain acylcarnitines (PMID: 30540494). Many medium-chain acylcarnitines can serve as useful markers for inherited disorders of fatty acid metabolism. Carnitine octanoyltransferase (CrOT, EC:2.3.1.137) is responsible for the synthesis of all medium-chain (MCAC, C5-C12) and medium-length branched-chain acylcarnitines in peroxisomes (PMID: 10486279). The study of acylcarnitines is an active area of research and it is likely that many novel acylcarnitines will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered. An excellent review of the current state of knowledge for acylcarnitines is available at [Dambrova et al. 2021, Physiological Reviews].
