7-methoxy-1-(2-morpholinoethyl)-N-((1S,4R)-1,3,3-trimethylbicyclo[2.2.1]heptan-2-yl)-1H-indole-3-carboxamide (N-[(S)-fenchyl]-1-[2-(morpholin-4-yl)ethyl]-7-methoxyindole-3-carboxamide, UR-12, MN-25) is a drug invented by Bristol-Myers Squibb, that acts as a reasonably selective agonist of peripheral cannabinoid receptors. It has moderate affinity for CB2 receptors with a Ki of 11nM, but 22x lower affinity for the psychoactive CB1 receptors with a Ki of 245nM. The indole 2-methyl derivative has the ratio of affinities reversed however, with a Ki of 8nM at CB1 and 29nM at CB2, which contrasts with the usual trend of 2-methyl derivatives having increased selectivity for CB2 (cf. JWH-018 vs JWH-007, JWH-081 vs JWH-098).


2-methyl derivative

Chemically, it is closely related to another indole-3-carboxamide synthetic cannabinoid, Org 28611, but with a different cycloalkyl substitution on the carboxamide, and the cyclohexylmethyl group replaced by morpholinylethyl, as in JWH-200 or A-796,260. Early compounds such as these have subsequently led to the development of a large number of related indole-3-carboxamide cannabinoid ligands.
