# JWH-309

JWH-309 (naphthalen-1-yl-(5-naphthalen-1-yl-1-pentylpyrrol-3-yl)methanone) is a synthetic cannabinoid from the naphthoylpyrrole family which acts as an agonist of the $CB_1$ $(K_i$ = 41 ± 3nM) and $CB_2$ $(K_i$ = 49 ± 7nM) receptors, displaying a slight selectivity for the former. JWH-309 was first synthesized in 2006 by John W. Huffman and colleagues to examine the nature of ligand binding to the $CB_1$ receptor.
