JWH-145 (1-naphthalenyl(1-pentyl-5-phenyl-1H-pyrrol-3-yl)-methanone) is a synthetic cannabinoid from the naphthoylpyrrole family which acts as an agonist of the CB1 (Ki = 14 ± 2nM) and CB2 (Ki = 6.4 ± 0.4nM) receptors, with a moderate (~2.2x) selectivity for the CB2 receptor. JWH-145 was first synthesized in 2006 by John W. Huffman and colleagues to examine the nature of ligand binding to the CB1 receptor.
