Discontinued Product
SR 33805 oxalate (Cat. No. 1806) has been withdrawn from sale for commercial reasons.
Description: CaV1.x blocker; binds allosterically to distinct site
Chemical Name: 3,4-Dimethoxy-N-methyl-N-[3-[4-[[1-methyl-3-(1-methylethyl)-1H-indol-2-yl]sulfonyl]phenoxy]propyl]benzeneethanamine
Purity: ≥99% (HPLC)
Biological Activity for SR 33805 oxalate
Potent Ca2+ channel antagonist; binds allosterically to the a1-subunit of L-type Ca2+ channels (Kd = 20 pM), at a site distinct from other types of blocker. Shows some selectivity for vascular smooth muscle, inducing vasorelaxation without producing inotropic or chronotropic effects. Inhibits PDGF-stimulated smooth muscle cell proliferation.
