OMDM-5 is a selective anandamide cellular uptake (ACU)inhibitor(Ki of 4.8 μM).

OMDM-1 ((Z)-N-[(2S)-1-hydroxy-3-(4-hydroxyphenyl)propan-2-yl]octadec-9-enamide) is a selective and metabolically stable anandamide cellular uptake (ACU)inhibitor with a Ki of 2.4 μM.

Several different arachidonoyl amino acids, including N-arachidonoyl-L-alanine (NALA), have been isolated and characterized from bovine brain. The glycine congener (NAGly) was further characterized and found to suppress formalin-induced pain in rats. NALA may have activity at cannabinoid receptor and/or VR1, but has not been fully characterized to date.

Vanilloid TRPV1 (VR1) receptor antagonist peptide (IC50 ~ 0.1 μM); blocks Ca2+ currents in dorsal root ganglion neurons. Analgesic in vivo.

Dihydrocapsaicin (CCRIS1589) is isolated from Capsicum fruit. Capsaicin is the primary active component of the heat and pain-eliciting lipid soluble fraction of the Capsicum pepper. Like capsaicin, dihydrocapsaicin is an irritant. Capsaicin is found in natural hot pepper extracts along with a number of impurities, including dihydrocapsaicin and several lesser impurities. Separation by HPLC is required in order to obtain pure dihydrocapsaicin. Dihydrocapsaicin represents about 10% of the compound present in commercial preparations purporting to be pure capsaicin, but it has about the same pungency as capsaicin. VR1 (vanilloid receptor 1) is a heat activated calcium ion channel which functions as a part of the normal nociceptive pain pathway. Capsaicin elicits a sensation of burning pain by activation of VR1 on small, non-myelinated polymodal C-type nociceptive nerve fibers. The potency of dihydrocapsaicin at VR1 appears equivalent to capsaicin. Antioxidant. Reduces oxidation of serum lipids. Mutagenic. Dihydrocapsaicin is an activator of VR1.

N-Arachidonoyl-L-serine (ARA-S), a recently isolated endocannabinoid with a distinct activity profile that diverges from typical endocannabinoids, does not interact with central cannabinoid (CB1), peripheral cannabinoid (CB2) receptors, or vanilloid receptor 1 (VR1). Unlike other compounds, ARA-S (5 mg/kg) counteracts the lowering of blood pressure induced by a 10 mg/kg intravenous bolus of abnormal cannabidiol (Abn-CBD) in anesthetized rat models. Additionally, akin to Abn-CBD, ARA-S induces relaxation in isolated rat mesenteric arteries and abdominal aorta and promotes phosphorylation of Akt and mitogen-activated protein kinase (MAPK) in human umbilical vein endothelial cells (HUVEC). The mechanisms through which ARA-S and Abn-CBD exert their effects on vascular systems show variations and merit deeper investigation.

Capsaicin is the primary active component of the heat and pain-eliciting lipid soluble fraction of the Capsicum pepper. Capsaicin signals are transduced by a heat-activated ion channel, the vanilloid receptor 1 (VR1), or transient receptor potential vanilloid 1 (TRPV1). CAY10448 is an iodinated nonivamide, a potent capsaicin receptor antagonist with an IC50 value of approximately 10 nM.

L-R4W2 TFA acts as a potent antagonist of vanilloid receptor 1 (VR1, TRPV1), demonstrating significant inhibitory activity with an IC50 value of 0.1 μM. This compound potentially offers powerful analgesic properties [1] [2].
