N-Arachidonoyl dopamine (NADA) is an endocannabinoid that acts as an agonist of the CB1 receptor and the transient receptor potential V1 (TRPV1) ion channel. NADA was first described as a putative endocannabinoid (agonist for the CB1 receptor) in 2000 [1] and was subsequently identified as an endovanilloid (agonist for TRPV1) in 2002. [2] NADA is an endogenous arachidonic acid based lipid found in the brain of rats, with especially high concentrations in the hippocampus, cerebellum, and striatum. [2] It activates the TRPV1 channel with an EC50 of approximately of 50 nM which makes it the putative endogenous TRPV1 agonist. [2]

Contents

In mice, NADA was shown to induce the tetrad of physiological paradigms associated with cannabinoids: hypothermia, hypo-locomotion, catalepsy, and analgesia. [1] [3] [4] NADA has been found to play a regulatory role in both the peripheral and central nervous systems, and displays antioxidant and neuroprotectant properties. [2] [5] [6] [7] NADA has also been implicated in smooth muscle contraction and vasorelaxation in blood vessels. [8] [9] [10] [11] Additionally, NADA has been observed to suppress inflammatory activation of human Jurkat T cells and to inhibit the release of prostaglandin E2 (PGE2) from lipopolysaccharide (LPS)-activated astrocytes, microglia and mouse brain ECs (MEC-Brain). [12] [13] [14] NADA also promotes the inflammatory resolution of human endothelial cells activated by both endogenous (i.e. TNF) and exogenous (i.e. bacterial derived LPS (TLR4 agonist) and FSL-1 (TLR2/6 agonist)) inflammatory mediators. [15] It can increase the TRPV1-mediated release of substance P and calcitonin gene-related peptide (CGRP) in rat dorsal spinal cord slices. [2] Furthermore, NADA also displays inhibitory activity in HIV-1 replication assays. [16] Finally, NADA can prevent the degranulation and release of TNF from RBL- 2H3 mast cells treated with an IgE-antigen complex. [17] Together, these studies show that physiological functions attributed to NADA are multifaceted, and include the ability to modulate the immune response.

The biosynthetic pathway of N-arachindonoyldopamine is not well understood. It has been proposed to be conjugated from arachidonoyl-CoA or arachidonoyl phospholipids and dopamine, but in vitro experiments do not support this theory. [18] However, the indirect biosynthesis of phospholipid esters with dopamine may be possible, as dopamine can induce the aminolysis of the glycerol-fatty acid bonds in phospholipid chains (arachidonoyl, palmitoyl, linoleyl, etc.). [19]

<span class="mw-page-title-main">Anandamide</span> Chemical compound (fatty acid neurotransmitter)

Anandamide (ANA), also known as N-arachidonoylethanolamine (AEA), is a fatty acid neurotransmitter. Anandamide was the first endocannabinoid to be discovered: it participates in the body's endocannabinoid system by binding to cannabinoid receptors, the same receptors that the psychoactive compound THC in cannabis acts on. Anandamide is found in nearly all tissues in a wide range of animals. Anandamide has also been found in plants, including small amounts in chocolate. The name 'anandamide' is taken from the Sanskrit word ananda, which means "joy, bliss, delight", plus amide.

<span class="mw-page-title-main">Cannabinoid</span> Compounds found in cannabis

Cannabinoids are several structural classes of compounds found in the cannabis plant primarily and most animal organisms or as synthetic compounds. The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC) (delta-9-THC), the primary intoxicating compound in cannabis. Cannabidiol (CBD) is a major constituent of temperate Cannabis plants and a minor constituent in tropical varieties. At least 113 distinct phytocannabinoids have been isolated from cannabis, although only four 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.

<span class="mw-page-title-main">Cannabinoid receptor</span> Group of receptors to cannabinoid compounds

Cannabinoid receptors, located throughout the body, are part of the endocannabinoid system – a class of cell membrane receptors in the G protein-coupled receptor superfamily. As is typical of G protein-coupled receptors, the cannabinoid receptors contain seven transmembrane spanning domains. Cannabinoid receptors are activated by three major groups of ligands: endocannabinoids; plant cannabinoids ; and synthetic cannabinoids. All of the endocannabinoids and phytocannabinoids are lipophilic.

The endocannabinoid system (ECS) is a biological system composed of endocannabinoids, which are endogenous lipid-based retrograde neurotransmitters that bind to cannabinoid receptors (CBRs), and cannabinoid receptor proteins that are expressed throughout the vertebrate central nervous system and peripheral nervous system. The endocannabinoid system remains under preliminary research, but may be involved in regulating physiological and cognitive processes, including fertility, pregnancy, pre- and postnatal development, various activity of immune system, appetite, pain-sensation, mood, and memory, and in mediating the pharmacological effects of cannabis. The ECS plays an important role in multiple aspects of neural functions, including the control of movement and motor coordination, learning and memory, emotion and motivation, addictive-like behavior and pain modulation, among others.

<span class="mw-page-title-main">2-Arachidonoylglycerol</span> Chemical compound

2-Arachidonoylglycerol (2-AG) is an endocannabinoid, an endogenous agonist of the CB1 receptor and the primary endogenous ligand for the CB2 receptor. It is an ester formed from the omega-6 fatty acid arachidonic acid and glycerol. It is present at relatively high levels in the central nervous system, with cannabinoid neuromodulatory effects. It has been found in maternal bovine and human milk. The chemical was first described in 1994-1995, although it had been discovered some time before that. The activities of phospholipase C (PLC) and diacylglycerol lipase (DAGL) mediate its formation. 2-AG is synthesized from arachidonic acid-containing diacylglycerol (DAG).

<span class="mw-page-title-main">Cannabinoid receptor type 2</span> Mammalian protein found in Homo sapiens

The cannabinoid receptor type 2, abbreviated as CB2, is a G protein-coupled receptor from the cannabinoid receptor family that in humans is encoded by the CNR2 gene. It is closely related to the cannabinoid receptor type 1 (CB1), which is largely responsible for the efficacy of endocannabinoid-mediated presynaptic-inhibition, the psychoactive properties of tetrahydrocannabinol (THC), the active agent in cannabis, and other phytocannabinoids (plant cannabinoids). The principal endogenous ligand for the CB2 receptor is 2-Arachidonoylglycerol (2-AG).

A cannabinoid receptor antagonist, also known simply as a cannabinoid antagonist or as an anticannabinoid, is a type of cannabinoidergic drug that binds to cannabinoid receptors (CBR) and prevents their activation by endocannabinoids. They include antagonists, inverse agonists, and antibodies of CBRs. The discovery of the endocannabinoid system led to the development of CB1 receptor antagonists. The first CBR inverse agonist, rimonabant, was described in 1994. Rimonabant blocks the CB1 receptor selectively and has been shown to decrease food intake and regulate body-weight gain. The prevalence of obesity worldwide is increasing dramatically and has a great impact on public health. The lack of efficient and well-tolerated drugs to cure obesity has led to an increased interest in research and development of CBR antagonists. Cannabidiol (CBD), a naturally occurring cannabinoid, is a non-competitive CB1/CB2 receptor antagonist. And Δ9-tetrahydrocannabivarin (THCV), a naturally occurring cannabinoid, modulate the effects of THC via direct blockade of cannabinoid CB1 receptors, thus behaving like first-generation CB1 receptor inverse agonists, such as rimonabant. CBD is a very low-affinity CB1 ligand, that can nevertheless affect CB1 receptor activity in vivo in an indirect manner, while THCV is a high-affinity CB1 receptor ligand and potent antagonist in vitro and yet only occasionally produces effects in vivo resulting from CB1 receptor antagonism. THCV has also high affinity for CB2 receptors and signals as a partial agonist, differing from both CBD and rimonabant.

<i>N</i>-Acylethanolamine Class of chemical compounds

An N-acylethanolamine (NAE) is a type of fatty acid amide where one of several types of acyl groups is linked to the nitrogen atom of ethanolamine, and is highly metabolic formed by intake of essential fatty acids through diet by 20:4, n-6 and 22:6, n-3 fatty acids, and when the body is physically and psychologically active. These amides conceptually can be formed from a fatty acid and ethanolamine with the release of a molecule of water, but the known biological synthesis uses a specific phospholipase D to cleave the phospholipid unit from N-acylphosphatidylethanolamines. Another route relies on the transesterification of acyl groups from phosphatidylcholine by an N-acyltransferase (NAT) activity. The suffixes -amine and -amide in these names each refer to the single nitrogen atom of ethanolamine that links the compound together: it is termed "amine" in ethanolamine because it is considered as a free terminal nitrogen in that subunit, while it is termed "amide" when it is considered in association with the adjacent carbonyl group of the acyl subunit. Names for these compounds may be encountered with either "amide" or "amine" varying by author.

<span class="mw-page-title-main">Arachidonoyl serotonin</span> Chemical compound

Arachidonoyl serotonin is an endogenous lipid signaling molecule. It was first described in 1998 as being an inhibitor of fatty acid amide hydrolase (FAAH).

In 2011, it was shown to be present in the ileum and jejunum of the gastrointestinal tract and modulate glucagon-like peptide-1 (GLP-1) secretion. In addition to this, in 2016, AA-5-HT was also found to affect the signaling mechanisms responsible for anxiety, by inhibiting dopamine release from the Basolateral amygdala following fear behavior. In 2017, AA-5-HT was tested in its effects on the sleep wake cycle, where it was found to affect the sleep homeostasis when used in conjunction with molecules and chemicals that affect wake-related neurotransmitters.

<i>N</i>-Arachidonylglycine Chemical compound

N-Arachidonylglycine (NAGly) is a carboxylic metabolite of the endocannabinoid anandamide (AEA). Since it was first synthesized in 1996, NAGly has been a primary focus of the relatively contemporary field of lipidomics due to its wide range of signaling targets in the brain, the immune system and throughout various other bodily systems. In combination with 2‐arachidonoyl glycerol (2‐AG), NAGly has enabled the identification of a family of lipids often referred to as endocannabinoids. Recently, NAGly has been found to bind to G-protein coupled receptor 18 (GPR18), the putative abnormal cannabidiol receptor. NaGly is an endogenous inhibitor of fatty acid amide hydrolase (FAAH) and thereby increases the ethanolamide endocannabinoids AEA, oleoylethanolamide (OEA) and palmitoylethanolamide (PEA) levels. NaGly is found throughout the body and research on its explicit functions is ongoing.

<i>N</i>-Acylamides

N-acyl amides are a general class of endogenous fatty acid compounds characterized by a fatty acyl group linked to a primary amine metabolite by an amide bond. Broadly speaking, N-acyl amides fall into several categories: amino acid conjugates, neurotransmitter conjugates, ethanolamine conjugates, and taurine conjugates. N-acyl amides have pleiotropic signaling functions in physiology, including in cardiovascular function, metabolic homeostasis, memory, cognition, pain, motor control and others. Initial attention focused on N-acyl amides present in mammalian organisms, however recently lipid signaling systems consisting of N-acyl amides have also been found to be present in invertebrates, such as Drosophila melanogaster. N-acyl amides play important roles in many biochemical pathways involved in a variety of physiological and pathological processes, as well as the metabolic enzymes, transporters, and receptors that regulate their signaling.
