SR33805是一种有效的Ca2+通道拮抗剂，在去极化和极化条件下的EC50值分别为4.1nM和33nM。SR33805阻止L型而不是T型Ca2+通道。SR33805可用于研究急性或慢性心脏衰竭。
SR33805 is a potent Ca2+ channel antagonist, with EC50s of 4.1 nM and 33 nM in depolarized and polarized conditions, respectively. SR33805 blocks L-type but not T-type Ca2+ channels. SR33805 can be used for the research of acute or chronic failing hearts[1][2].
SR33805 (0.01-10 µM; 3 d) inhibits growth factor-induced proliferation of SMC (0.20 SR33805 (20 mg/kg; a single i.p.) improves end-systolic strain and fractional shortening of MI hearts in rats[2].SR33805 (5 mg/kg/day; p.o. for 38 d) significantly reduces intimal hyperplasia in pigs[3]. Animal Model: Male Wistar rats (5 weeks) are subjected to coronary artery ligature[2] [1]. Romey G, et, al.
