Docosatetraenoylethanolamide
Docosatetraenoylethanolamide (DEA) (Adrenoyl-ethanolamide) (Adrenoyl-EA) is an endogenous ethanolamide that has been shown to act on the cannabinoid (CB1) receptor. DEA is similar in structure to anandamide (AEA, a recognized endogenous ligand for the CB1 receptor), containing docosatetraenoic acid in place of arachidonic acid. While DEA has been shown to bind to the CB1 receptor with similar potency and efficacy as AEA, its role as a cannabinergic neurotransmitter is not well understood. Docosatetraenoylethanolamide (DEA) has been found in Tropaeolum tuberosum ''Tropaeolum tuberosum'' (mashua, see below for other names) is a species of flowering plant in the family Tropaeolaceae, grown in the Andes, particularly in Peru and Bolivia, and to a lesser extent in Ecuador as well as in some areas of Colombi ...

Endocannabinoids
Cannabinoids () are several structural classes of compounds found primarily in the ''Cannabis'' plant or as synthetic compounds. The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC) (delta-9-THC), the primary psychoactive compound in Cannabis (drug), cannabis. Cannabidiol (CBD) is also a major constituent of temperate cannabis plants and a minor constituent in tropical varieties. At least 100 distinct phytocannabinoids have been isolated from cannabis, although only four (i.e., THCA, CBDA, CBCA and their common precursor CBGA) have been demonstrated to have a biogenetic origin. It was reported in 2020 that phytocannabinoids can be found in other plants such as rhododendron, licorice and liverwort, and earlier in Echinacea. Phytocannabinoids are multi-ring phenolic compounds structurally related to THC, but endocannabinoids are fatty acid derivatives. Nonclassical synthetic cannabinoids (cannabimimetics) include aminoalkylindoles, 1,5-diarylpyrazoles, qu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannabinoid Receptor Type 1
Cannabinoid receptor 1 (CB1), is a G protein-coupled cannabinoid receptor that in humans is encoded by the ''CNR1'' gene. And discovered, by determination and characterization in 1988, and cloned in 1990 for the first time. The human CB1 receptor is expressed in the peripheral nervous system and central nervous system. It is activated by endogenous cannabinoids called endocannabinoids, a group of retrograde neurotransmitters that include lipids, such as anandamide and 2-arachidonoylglycerol; plant phytocannabinoids, such as docosatetraenoylethanolamide found in wild dagga, the compound tetrahydrocannabinol which is an active constituent of the psychoactive drug cannabis; and synthetic analogs of tetrahydrocannabinol. CB1 is antagonized by the phytocannabinoid tetrahydrocannabivarin at low doses and at higher doses, it activates the CB1 receptor as an agonist, but with less potency than tetrahydrocannabinol. The primary endogenous agonist of the human CB1 receptor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropaeolum Tuberosum
''Tropaeolum tuberosum'' (mashua, see below for other names) is a species of flowering plant in the family Tropaeolaceae, grown in the Andes, particularly in Peru and Bolivia, and to a lesser extent in Ecuador as well as in some areas of Colombia, for its edible tubers, which are eaten cooked or roasted as a vegetable. It is a minor food source, especially for native Amerindian populations. Mashua is a herbaceous perennial climber growing to in height. It is related to garden nasturtiums, and is occasionally cultivated as an ornamental for its brightly coloured tubular flowers. The leaves are peltate, roundly five-lobed with a petiole that twines weakly but is not truly a tendril. The root is tuberous. Alternative names This plant is commonly called mashua in Peru and Ecuador, but other names include: In Boyacá, Colombia, it is also named nabu Agronomy The plant thrives even in marginal soils and competes well with weeds.

Endogeny (biology)
Endogeny, in biology, refers to the property of originating or developing from within an organism, Tissue (biology), tissue, or Cell (biology), cell. For example, ''endogenous substances'', and ''endogenous processes'' are those that originate within a living system (e.g. an organism or a Cell (biology), cell). For instance, estradiol is an endogenous estrogen hormone produced within the body, whereas ethinylestradiol is an exogenous synthetic estrogen, commonly used in birth control pills. In contrast, ''Exogeny#Biology, exogenous substances'' and ''exogenous'' ''processes'' are those that originate from outside of an organism.

Ethanolamide
Ethanolamides are chemical compounds which are amides formed from carboxylic acids and ethanolamine. Some ethanolamides are naturally occurring, such as anandamide, palmitoylethanolamide and prostamides, which play physiological roles as lipid neurotransmitters and autacoids. The crystal structure of the membrane enzyme NAPE-PLD has revealed how these endogenous ethanolamides are generated from cell membranes, and that bile acids play a role in their production. Ethanolamides can be prepared synthetically by heating esters with ethanolamine. See also * Diethanolamide * Docosatetraenoylethanolamide * Oleoylethanolamide Oleoylethanolamide (OEA) is an endogenous peroxisome proliferator-activated receptor alpha ( PPAR-α) agonist.

Anandamide
Anandamide (ANA), also referred to as ''N''-arachidonoylethanolamine (AEA) is a fatty acid neurotransmitter belonging to the fatty acid derivative group known as N-acylethanolamine (NAE). Anandamide takes its name from the Sanskrit word ''ananda'' ( आनन्द), meaning "joy, bliss, delight," plus amide. Anandamide, the first discovered endocannabinoid, engages with the body's endocannabinoid system by binding to the same cannabinoid receptors that THC found in cannabis acts on. Anandamide can be found within tissues in a wide range of animals. It has also been found in plants, such as the cacao tree. Anandamide is derived from the non-oxidative metabolism of arachidonic acid, an essential omega-6 fatty acid. It is synthesized from ''N''-arachidonoyl phosphatidylethanolamine by multiple pathways. It is degraded primarily by the fatty acid amide hydrolase (FAAH) enzyme, which converts anandamide into ethanolamine and arachidonic acid. As such, inhibitors of FAAH lead to ...

Docosatetraenoic Acid
Docosatetraenoic acid designates any straight chain 22:4 fatty acid. (''See'' Essential fatty acid for nomenclature.) One isomer is of particular interest: * all-''cis''-7,10,13,16-docosatetraenoic acid is an ω-6 fatty acid with the common name adrenic acid (AdA). This is a naturally occurring polyunsaturated fatty acid formed through a 2-carbon chain elongation of arachidonic acid. It is one of the most abundant fatty acids in the early human brain. This unsaturated fatty acid is also metabolized by cells to biologically active products viz., dihomoprostaglandins, and epoxydocosatrienoic acids (EDTs, also known as dihomo- EETs). In addition to being endothelium-derived hyperpolarizing factors, EDTs have demonstrated anti-endoplasmic reticulum stress and anti-nociceptive activities. They are hydrolyzed by the soluble epoxide hydrolase (sEH) to dihydroxydocosatrienoic acids (DHDTs) and hence might play a role in the efficacy of sEH inhibitors. See also *Polyunsaturated fat ...

Arachidonic Acid
Arachidonic acid (AA, sometimes ARA) is a polyunsaturated omega−6 fatty acid 20:4(ω−6), or 20:4(5,8,11,14). It is a precursor in the formation of leukotrienes, prostaglandins, and thromboxanes. Together with omega−3 fatty acids and other omega−6 fatty acids, arachidonic acid provides energy for body functions, contributes to cell membrane structure, and participates in the synthesis of eicosanoids, which have numerous roles in physiology as signaling molecules. Its name derives from the ancient Greek neologism ''arachis'' 'peanut', although peanut oil does not contain any arachidonic acid. Arachidonate is the name of the derived carboxylate anion ( conjugate base of the acid), salts, and some esters. Chemistry In chemical structure, arachidonic acid is a carboxylic acid with a 20-carbon chain and four '' cis''- double bonds; the first double bond is located at the sixth carbon from the omega end. Some chemistry sources define 'arachidonic acid' to designa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fatty Acid Amides
Fatty acid amides (FAAs) are amides formed from a fatty acid and an amine. In nature, many FAAs have ethanolamine as the amine component. Also known as ''N''-acylethanolamines, they contain the functionality RC(O)N(H)CH2CH2OH. A well known example is anandamide. Other fatty acid amides are fatty acid primary amides (FAPAs). They contain the functionality RC(O)NH2). Oleamide is an example of this class of FAPAs. Natural occurrences FAAs play a role in intracellular signalling. The signalling is controlled in part by fatty acid amide hydrolases, which convert the amide to the parent fatty acid. One example of signaling is induced by the binding of anandamide to the cannabinoid receptors. Aliphatic amides can be found in ''Zanthoxylum'' species found in Nigeria.The Nigerian Zanthoxylum; Chemical and biological values. S. K. Adesina, Afr. J. Trad.
