L-type calcium channel |
Benzothiazepine Ca2+ antagonist diltiazem hydrochloride interacts with transmembrane segments IIIS6 and IVS6 in the α1 subunit of L-type Ca2+ channels[1].
Diltiazem causes a dose-dependent inhibiton of contractions as well as Ca2+ influx stimulated by alpha adrenoceptor activation and high-K+ depolarization. Diltiazem is roughly equally potent in inhibiting contractions induced by high-K+ and a low concentration of norepinephrine (NE)[2].
Diltiazem also inhibits the Na-dependent Ca-efflux from heart mitochondria. Both the (+)-optical isomers of the cis- and trans-forms of diltiazem inhibit Na-Ca exchange activity with comparable potency (IC50 of 10-20 μM)[3].
