3,4-Dihydroquinazoline derivatives as novel selective T-type Ca2+ channel blockers
摘要:
For LVA T-type Ca2+ channel blockers, 3,4-dihydroquinazoline derivatives as new scaffolds were prepared and evaluated for the inhibitory activity against two members of the recombinant T-type Ca2+ channel family. Among them, 8a (KYS05001, IC50 = 0-9 muM) was nearly equipotent with mibefradil (IC50 = 0.84 muM) and inhibited LVA T-type Ca2+ channel with greater efficacy than HVA Ca2+ channel.
