Synthesis and biological evaluation of novel T-type calcium channel blockers
摘要:
3,4-Dihydroquinazoline analogues substituted by N-methyl-N-(5-pyrrolidinopentyl)amine at the 2-position were synthesized and their blocking effects were evaluated for T- and N-type calcium channels. Compound 11b (KYS05080), compared to mibefradil (IC50 = 1.34 0.49 mu M), was about 5-fold potent (IC50 = 0.26 +/- 0.01 mu M) for T-type calcium channel (alpha(1)G) blocking and its selectivity of T/N-type was also improved (7.5 versus 1.4 of mibefradil).

The present invention relates to 3,4-dihydroquinazoline derivatives, a process of preparing them and a pharmaceutical composition including them. The 3,4-dihydroquinazoline derivatives of the present invention have excellent T-type calcium channel blocking effect and anti-cancer activity.
