生物活性

SR33805 is a potent Ca 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 Ca channels. SR33805 can be used for the research of acute or chronic failing hearts.

体外研究

SR33805 (0.01-10 µM; 3 d) inhibits growth factor-induced proliferation of SMC (0.2050<0.46 µM) in a dose-dependent manner.
SR33805 (10 µM; 10 min) restores the myocardial infarction (MI)-altered cell shortening without affecting the Ca transient amplitude.
SR33805 (10 µM) decreases the activity of recombinant PKA.

Cell Viability Assay

Cell Line: Smooth muscle cells (SMC)
Concentration: 0.01, 0.1, 1, 10 µM
Incubation Time: 3 days
Result: Inhibited in a dose-dependent manner FCS-, bFGF and PDGF-induced proliferation of porcine SMC with IC50s of 0.26±0.08, 0.46±0.1 and 0.20±0.04 µM, respectively.
体内研究

SR33805 (20 mg/kg; a single i.p.) improves end-systolic strain and fractional shortening of MI hearts in rats.
SR33805 (5 mg/kg/day; p.o. for 38 d) significantly reduces intimal hyperplasia in pigs.

Animal Model: Male Wistar rats (5 weeks) are subjected to coronary artery ligature
Dosage: 0.2, 2, 20 mg/kg
Administration: A single i.p. injection
Result: Increased significantly both end-systolic strain (ESS) and fractional shortening (FS) by about +38 and +26%, respectively at the dose of 20 mg/kg.
Did not affect other contractile parameters.
