Capecitabine is an orally-administered chemotherapeutic agent used in the treatment of metastatic breast and colorectal cancers. Capecitabine is a prodrug, that is enzymatically converted to fluorouracil (antimetabolite) in the tumor, where it inhibits DNA synthesis and slows growth of tumor tissue.

Grepafloxacin hydrochloride (Raxar®, Glaxo Wellcome) is an oral broad-spectrum quinoline antibacterial agent used to treat bacterial infections. Grepafloxacin was withdrawn in the United States due to its side effect of lengthening the QT interval on the electrocardiogram, leading to cardiac events and sudden death.

C19H22FN3O3 (359.16451140000004)

Enrofloxacin is a veterinary antibacterial agent, used in poultry. Enrofloxacin is a fluoroquinolone antibiotic sold by the Bayer Corporation under the trade name Baytril(r). Enrofloxacin is currently FDA-approved for treatment of individual pets and domestic animals in the United States. In September 2005, the FDA withdrew approval of Baytril for use in water to treat flocks of poultry, as this practice was noted to promote the evolution of fluoroquinolone-resistant strains of the bacterium Campylobacter, a human pathogen. Fluoroquinolones such as ciprofloxacin are widely used in the treatment of human disease. Enrofloxacin is a synthetic chemotherapeutic agent from the class of the fluoroquinolone carboxylic acid derivatives. It has antibacterial activity against a broad spectrum of Gram-negative and Gram-positive bacteria. Its mechanism of action is not thoroughly understood, but it is believed to act by inhibiting bacterial DNA gyrase (a type-II topoisomerase), thereby preventing DNA supercoiling and DNA synthesis. It is a bactericidal agent. The bactericidal activity of enrofloxacin is concentration dependent, with susceptible bacteria cell death occurring within 20-30 minutes of exposure. Enrofloxacin has demonstrated a significant post-antibiotic effect for both Gram-negative and Gram-positive bacteria and is active in both stationary and growth phases of bacterial replication. http://www.fda.gov/cvm/Documents/baytrilDDL.pdf is a broken lin D000890 - Anti-Infective Agents > D000900 - Anti-Bacterial Agents > D024841 - Fluoroquinolones C254 - Anti-Infective Agent > C258 - Antibiotic > C795 - Quinolone Antibiotic

Norendoxifen

4-[(1Z)-1-[4-(2-aminoethoxy)phenyl]-2-phenylbut-1-en-1-yl]phenol

C24H25NO2 (359.188519)

Norendoxifen is a metabolite of tamoxifen. Tamoxifen is an antagonist of the estrogen receptor in breast tissue via its active metabolite, hydroxytamoxifen. In other tissues such as the endometrium, it behaves as an agonist, and thus may be characterized as a mixed agonist/antagonist. Tamoxifen is the usual endocrine therapy for hormone receptor-positive breast cancer in pre-menopausal women, and is also a standard in post-menopausal women although aromatase inhibitors are also frequently used in that setting.

5-Hydroxydec-6-enedioylcarnitine

3-[(9-carboxy-5-hydroxynon-6-enoyl)oxy]-4-(trimethylazaniumyl)butanoate

C17H29NO7 (359.19439239999997)

5-Hydroxydec-6-enedioylcarnitine is an acylcarnitine. More specifically, it is an 5-hydroxydec-6-enedioic 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. 5-Hydroxydec-6-enedioylcarnitine is therefore classified as a medium chain AC. As a medium-chain acylcarnitine 5-Hydroxydec-6-enedioylcarnitine 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.
