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.
