3,4‐Dihydroquinazoline derivatives have been known to be the novel and potent T‐type calcium channel blockers. From a systematic variation of 3,4‐dihydroquinazoline derivative 5c ( KYS05043 ), plausible SAR results were established. It was revealed that a 5‐(dimethylamino)pentylamino group at R 1 , a biphenyl group at R 2 , and a benzyl amido group at R 3 in the 3,4‐dihydroquinazoline backbone are closely related with the channel selectivity (T/N‐type) as well as the potency based on the discovery of 6k ( KYS05090 ).
