C25H27NO2 (373.2041682)

Endoxifen (EDX) is a key active metabolite of tamoxifen (TAM) with higher affinity and specificity to estrogen receptors that also inhibits aromatase activity. (PMID: 23274567) 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. (Wikipedia) The pharmacological activity of Tamoxifen is dependent on its conversion to its active metabolite, endoxifen, by CYP2D6. (PMID: 23711794) Tamoxifen is a largely inactive pro-drug, requiring metabolism into its most important metabolite endoxifen. Since the cytochrome P450 (CYP) 2D6 enzyme is primarily involved in this metabolism, genetic polymorphisms of this enzyme, but also drug-induced CYP2D6 inhibition can result in considerably reduced endoxifen formation and as a consequence may affect the efficacy of tamoxifen treatment.

Dodecanedioylcarnitine is classified as a tricarboxylic acid or a Tricarboxylic acid derivative. Tricarboxylic acids are carboxylic acids containing exactly three carboxyl groups. Dodecanedioylcarnitine is considered to be a practically insoluble (in water) and a weak acidic compound. Dodecanedioylcarnitine can be found in blood.

O-(11-Carboxyundecanoyl)carnitine

3-[(11-Carboxyundecanoyl)oxy]-4-(trimethylammonio)butanoic acid

C19H35NO6 (373.24642500000004)

O-(11-Carboxyundecanoyl)carnitine is an acylcarnitine. More specifically, it is an dodecanedioic 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. O-(11-Carboxyundecanoyl)carnitine is therefore classified as a medium chain AC. As a medium-chain acylcarnitine O-(11-Carboxyundecanoyl)carnitine 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].

N-Eicosapentaenoyl Alanine

2-(icosa-5,8,11,14,17-pentaenamido)propanoic acid

C23H35NO3 (373.26168000000007)

N-eicosapentaenoyl alanine belongs to the class of compounds known as N-acylamides. These are molecules characterized by a fatty acyl group linked to a primary amine by an amide bond. More specifically, it is an Eicosapentaenoic acid amide of Alanine. It is believed that there are more than 800 types of N-acylamides in the human body. N-acylamides fall into several categories: amino acid conjugates (e.g., those acyl amides conjugated with amino acids), neurotransmitter conjugates (e.g., those acylamides conjugated with neurotransmitters), ethanolamine conjugates (e.g., those acylamides conjugated to ethanolamine), and taurine conjugates (e.g., those acyamides conjugated to taurine). N-Eicosapentaenoyl Alanine is an amino acid conjugate. N-acylamides can be classified into 9 different categories depending on the size of their acyl-group: 1) short-chain N-acylamides; 2) medium-chain N-acylamides; 3) long-chain N-acylamides; and 4) very long-chain N-acylamides; 5) hydroxy N-acylamides; 6) branched chain N-acylamides; 7) unsaturated N-acylamides; 8) dicarboxylic N-acylamides and 9) miscellaneous N-acylamides. N-Eicosapentaenoyl Alanine is therefore classified as a long chain N-acylamide. N-acyl amides have a variety of signaling functions in physiology, including in cardiovascular activity, metabolic homeostasis, memory, cognition, pain, motor control and others (PMID: 15655504). N-acyl amides have also been shown to play a role in cell migration, inflammation and certain pathological conditions such as diabetes, cancer, neurodegenerative disease, and obesity (PMID: 23144998; PMID: 25136293; PMID: 28854168).N-acyl amides can be synthesized both endogenously and by gut microbiota (PMID: 28854168). N-acylamides can be biosynthesized via different routes, depending on the parent amine group. N-acyl ethanolamines (NAEs) are formed via the hydrolysis of an unusual phospholipid precursor, N-acyl-phosphatidylethanolamine (NAPE), by a specific phospholipase D. N-acyl amino acids are synthesized via a circulating peptidase M20 domain containing 1 (PM20D1), which can catalyze the bidirectional the condensation and hydrolysis of a variety of N-acyl amino acids. The degradation of N-acylamides is largely mediated by an enzyme called fatty acid amide hydrolase (FAAH), which catalyzes the hydrolysis of N-acylamides into fatty acids and the biogenic amines. Many N-acylamides are involved in lipid signaling system through interactions with transient receptor potential channels (TRP). TRP channel proteins interact with N-acyl amides such as N-arachidonoyl ethanolamide (Anandamide), N-arachidonoyl dopamine and others in an opportunistic fashion (PMID: 23178153). This signaling system has been shown to play a role in the physiological processes involved in inflammation (PMID: 25136293). Other N-acyl amides, including N-oleoyl-glutamine, have also been characterized as TRP channel antagonists (PMID: 29967167). N-acylamides have also been shown to have G-protein-coupled receptors (GPCRs) binding activity (PMID: 28854168). The study of N-acylamides is an active area of research and it is likely that many novel N-acylamides will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered for these molecules.
