# JWH-366

JWH-366 (naphthalen-1-yl-(1-pentyl-5-pyridin-3-ylpyrrol-3-yl)methanone) is a synthetic cannabinoid from the naphthoylpyrrole family which acts as an agonist of the $CB_1$ $(K_i$ = 191 ± 12nM) and $CB_2$ $(K_i$ = 24 ± 1nM) receptors, with a strong (~8x) selectivity for the $CB_2$ receptor over the $CB_1$ receptor. JWH-366 was first synthesized in 2006 by John W. Huffman and colleagues to examine the nature of ligand binding to the $CB_1$ receptor.
