CB1 Agonist

Anandamide is an endocannabinoid. Anandamide modulates both neuronal and immune functions through two protein-coupled cannabinoid receptors (CB1 and CB2). Anandamide can activate numerous other receptors like PPARS, TRPV1, and GPR18/GPR55. Anandamide also has potential anti-fungal and anti-inflammatory activities. Anandamide can be used for the research of Alzheimer’s disease (AD) and ulcerative colitis.

RD-pepcan-11 is a CB1 receptor agonist. RD-pepcan-11 increases the relative phosphorylation level of ERK1/2. RD-pepcan-11 mediates analgesic effects through interaction with CB1 receptors in a carrageenan-induced mouse inflammatory pain model. RD-pepcan-11 can be used in studies related to inflammatory pain.

CB1-receptor agonist-1 is the racemic form of compound ‘1350 and is also a cannabinoid-1 receptor (CB1R) agonist.

Synaptamide (Dehydroepiandrosteron; DHEA) is an endogenous metabolite and structural analogue of Anandamide. Synaptamide binds to both the cannabinoid-1 and 2 (CB1 and CB2) cannabinoid receptors and has anti-inflammatory properties. Synaptamide is the first small-molecule endogenous ligand of an adhesion G protein-coupled receptor (aGPCR) .

Leelamine is an orally active pyruvate dehydrogenase kinase (PDK) inhibitor with an IC₅₀ value of 9.5 μM, showing a blood glucose lowering effect in the diabetic mouse. Leelamine is also a weak agonist of cannabinoid receptors CB1 and CB2. Leelamine decreases mitotic activity, prostate-specific antigen expression and induces Apoptosis to cell death in cancer cells.

Tetrahydromagnolol (Magnolignan), the main metabolite of Magnolol, is a potent and selective cannabinoidCB2 receptor agonist (EC₅₀ =170 nM) and GPR55 antagonist. The K_i of Tetrahydromagnolol for CB2 is 416 nM, 20-fold higher than for the CB1 receptor. Magnolol shows antifungal, anti-inflammatory and analgesic effects.

GW-405833 (L768242) is a potent, selective cannabinoid receptor 2 (CB₂) agonist. GW405833 has EC₅₀ and K_i values ​​of 0.65 nM and 3.92 nM for CB₂, and EC₅₀ and K_i values ​​of 16.1 μM and 4772 nM for CB₁. GW-405833 also exhibits non-competitive CB₁ antagonist, exerting its analgesic and and anti-inflammatory effect through a CB₁ receptor (rather than CB₂) dependent mechanism. GW-405833 can significantly inhibit the production of cAMP stimulated by Forskolin (HY-15371). GW405833 inhibits glycolysis by down-regulating HIF-1α, thereby alleviating acute liver failure (ALF).

Leelamine hydrochloride is a tricyclic diterpene molecule that is extracted from the bark of pine trees. Leelamine hydrochloride is a cannabinoid receptor type 1 (CB1) agonist and a inhibitor of SREBP1-regulated fatty acid/lipid synthesis in prostate cancer cells that is not affected by androgen receptor status. Leelamine hydrochloride suppresses transcriptional activity of androgen receptor, which is known to regulate fatty acid synthesis^[2,3].

CB1/2 agonist 3 (compound 52), a potent non-selective cannabinoid ligand, is a CB1/CB2 (cannabinoid receptor) competitive agonist. CB1/2 agonist 3 acts on hCB1 and hCB2 with K_i values of 5.9 nM and 3.5 nM, respectively.

N-Arachidonyldopamine acts as an Anandamide (HY-10863) membrane transport inhibitor, a selective CB₁ cannabinoid receptor agonist, and a VR1 receptor activator. It exhibits an EC₅₀ value of 48 nM for rat VR1 and a K_i value of 0.25 μM for CB1. N-Arachidonyldopamine exists in mammalian neural tissues. It stimulates intracellular Ca²⁺ mobilization, mediates cannabinoid-like effects, and induces hypothermia, hypomotility, catalepsy, analgesia, and hyperalgesia to heat. N-Arachidonyldopamine possesses anticancer activity against breast cancer. It can be used in research related to breast cancer and heat hyperalgesia.

GW405833 (L768242) hydrochloride is a potent, selective cannabinoid receptor 2 (CB₂) agonist. GW405833 has EC₅₀ and K_i values ​​of 0.65 nM and 3.92 nM for CB₂, and EC₅₀ and K_i values ​​of 16.1 μM and 4772 nM for CB₁. GW405833 hydrochloride also exhibits non-competitive CB₁ antagonist, exerting its analgesic effect through a CB₁ receptor (rather than CB₂) dependent mechanism. GW405833 hydrochloride can significantly inhibit the production of cAMP stimulated by Forskolin (HY-15371). GW405833 hydrochloride inhibits glycolysis by down-regulating HIF-1α, thereby alleviating acute liver failure (ALF).

(R)-Methanandamide (AM-356), an analog of the endocannabinoid ligand Anandamide, is a potent CB1 agonist with a K_i of 20 nM. (R)-Methanandamide also activates vanilloid (TRPV1) receptors.

Eicosapentaenoyl ethanolamide, an omega-3 fatty acid, is one of N-acylethanolamines (NAEs). Eicosapentaenoyl ethanolamide is cannabinoid CB1/CB2 receptor agonist. Eicosapentaenoyl ethanolamide acts as a metabolic signal. Eicosapentaenoyl ethanolamide inhibits dietary restriction (DR)-induced lifespan extension in wild type animals and suppresses lifespan extension in a TOR pathway mutant.

CB1/2 agonist 1 is a potent and cross the blood-brain barrier CB1/2 agonist with EC₅₀s of 56.15, 11.63 nM for CB1R and CB2R, respectively. CB1/2 agonist 1 reduces glutamate release and LPS-induced activation of microglial cells. CB1/2 agonist 1 shows anti-inflammatory and antinociceptive effects. CB1/2 agonist 1 has the potential for the research of multiple sclerosis.

Dihomo-γ-Linolenoyl Ethanolamide, an endocannabinoid, is a cannabinoid (CB) receptor agonist with K_is of 857 nM and 598 nM for human recombinant CB1 and CB2 receptors, respectively.
