Tedalinab is an effective and selective cannabinoid receptor 2 agonist. Tedalinab has the potential for neuropathic pain and osteoarthritis treatment. Tedalinab has >4700-fold functional selectivity for CB2 over CB1.
(±)19(20)-EDP ethanolamide is an ω-3 endocannabinoid epoxide and cannabinoid (CB) receptoragonist (EC50s = 108 and 280 nM for CB1 and CB2, respectively). It is produced through direct epoxygenation of docosahexaenoyl ethanolamide by cytochrome P450 (CYP) epoxygenases. (±)19(20)-EDP ethanolamide (25 μM) reduces the viability of 143B metastatic osteosarcoma cells. It decreases the production of IL-6 and increases the production of IL-10 when used at concentrations ranging from 2.5 to 10 μM in BV-2 microglia stimulated by LPS and decreases LPS-induced cytotoxicity when used at concentrations ranging from 5 to 10 μM. It also decreases nitrite production when used at a concentration of 7.5 μM, an effect that can be partially reversed by the CB2 receptor antagonist AM630 and the PPARγ antagonist GW 9662 . (±)19(20)-EDP ethanolamide induces vasodilation of isolated preconstricted bovine coronary arteries (ED50 = 1.9 μM) and reduces tube formation by human microvascular endothelial cells (HMVECs) in a Matrigel assay.
Arachidonoyl 2-chloroethylamide (ACEA) is a potent and selective cannabinoid (CB) receptor 1 agonist with Ki values of 1.4 and >2,000 nM for CB1 and CB2 receptors, respectively. In whole animal experiments, ACEA induces hypothermia in mice with the same efficacy as arachidonoyl ethanolamide , in spite of its higher affinity for the CB1 receptor. These data have been interpreted to indicate that ACEA may be a substrate for fatty acid amide hydrolase (FAAH), and thus only transiently available in whole animal experiments.
(±)-WIN 55,212-2 is a potent aminoalkylindole cannabinoid (CB) receptoragonist with a Ki value of 62.3 and 3.3 nM for human recombinant central cannabinoid (CB1) and peripheral cannabinoid (CB2) receptors, respectively. In contrast, the enantiomer (-)-WIN 55,212-3 acts a partial inverse agonist at CB1 (pIC50 = 5.5) and as a competitive neutral antagonist of CB2, reversing the inverse agonism evoked by SR 144528 (pEC50 = 5.3). (+)-WIN 55,212 (mesylate) is a mixture of the two enantiomers, (+)-WIN 55,212-2 and (-)-WIN 55,212-3.
Vicasinabin, a potent agonist of cannabinoid receptor 2 (CB2), exhibits promising potential for researching chronic pain, atherosclerosis, regulation of bone mass, neuroinflammation, and related human diseases.
GW833972 is a CB2 Agonist. GW 833972A inhibited capsaicin-induced depolarization of the human and guinea-pig and prostaglandin E(2) (PGE(2)) and hypertonic saline-induced depolarization of the guinea-pig isolated vagus nerve in vitro. GW 833972A also inhibited citric acid-induced cough but not plasma extravasation in the guinea-pig and this effect was blocked by a CB(2) receptor antagonist.
RVD-Hpα TFA is the N-terminally extended form of human hemopressin that acts as a selectiveCB1receptoragonist. RVD-Hpα TFA increases intracellular Ca2+levels in cells expressingCB1receptors in vitro. RVD-Hpα TFA also high affinityCB2positive allosteric modulator (Ki=50 nM).
MCHB-1, a potent agonist of the human cannabinoid 2 (CB2) receptor (EC50= 0.52 nM), demonstrates high selectivity for CB2 over CB1 (Kis = 3.7 and 110 nM, respectively), distinguishing itself from similar benzimidazole compounds that significantly alleviate peripheral pain while minimizing central nervous system side effects in mice.
