Biochem/physiol Actions

R(+)-Methanandamide is metabolically stable congener of anandamide that has higher affinity for the cannabinoid receptor. Of the analogs tested, (R)-methanandamide exhibited the highest affinity for the cannabinoid receptor with a Ki of 20 +/- 1.6 nM, 4-fold lower than that of anandamide (Ki = 78 +/- 2 nM). (R)-methanandamide exhibits high stability to aminopeptidase hydrolysis. Experiments with mice have demonstrated that (R)-methanandamide also posseses cannabimimetric properties in vivo, as established by the four tests of hypothermia, hypokinesia, ring immobility, and antinociception.

Anandamide (AEA), a major endocannabinoid, binds to cannabinoid and vanilloid receptors (CB1, CB2 and TRPV1) and affects many reproductive functions. Nanomolar levels of anandamide are found in reproductive fluids including mid-cycle oviductal fluid. Previously, we found that R(+)-methanandamide, an anandamide
