摘要:
A small molecule library of piperazinylalkylisoxazole derivatives containing about 600 compounds was designed, synthesized and evaluated for blocking effects on T-type Ca2+ channel. Several ligands were identified to possess high inhibitory activity against the T-type Ca2+ channel. The compound 21 with trifluoromethyl substituents at C-3-position of phenyl group (W) and C-2-position of phenyl group (R-2) showed the highest inhibitory activity with IC50 value of 1.02 muM, which is comparable to that of mibefradil.
