Phenylaminojuglone AJ-2 is a nitric oxide synthase inhibitor that interacts with soluble guanylate cyclase, β-adrenergic receptor, CaV1.2 calcium channel, KV channel and KCa channel. Phenylaminojuglone AJ-2 blocks extracellular Ca2+ influx, regulates the activity of the NO−sGC−cGMP signaling pathway, and inhibits pharmacologic and electromechanical contractions of smooth muscle. Phenylaminojuglone AJ-2 is applicable to studies related to intestinal spasm.
