Abstract:
3-(4-Chloro)-4-oxo-2-thioxo-1,2,3,4-tetrahydro-quinazoline derivatives as T-type calcium channel antagonists are provided to treat neurogenic pain, epilepsy, hypertension or angina pectoris by inhibiting the T-type calcium channel without side effects such as pharmacokinetic interactions. 3-(4-chloro)-4-oxo-2-thioxo-1,2,3,4-tetrahydro-quinazoline derivatives represented by the formula(I) is used as a pharmaceutical composition, wherein X is (3-piperidin-1-yl-propyl)-amide, [3-(2-ethyl-piperidin-1-yl)-propyl]-amide, [3-(4-methyl-piperidin-1-yl)-propyl]-amide, 2-(butyl-methyl-amino)-ethyl-amide, (3-pyrrolidin-1-yl-propyl)-amide, (3-azepan-1-yl-propyl)-amide, [3-(4-ethyl-piperazin-1-yl)-propyl]-amide, [3-(benzyl-methyl-amide)-propyl]-amide or (2-dimethylamino-ethyl)-amide, and the compound represented by the formula(I) includes 3-(4-chloro-benzyl)-7-(4-methyl-piperazine-1-carbonyl)-2-thioxo-2,3-dihydro-1H-quinazolin-4-one.
Abstract:
Novel 1,3-dioxoisoindole derivatives having selective antagonism of T-type calcium channel are provided to treat brain diseases including epilepsy, hypertension and angina pectoris, heart disease and nerve system pain by inhibiting the T-type calcium channel as a representative low-voltage activated calcium channel. The 1,3-dioxoisoindole derivatives represented by the formula(1) or their pharmaceutically acceptable salts are provided, wherein R1 is phenyl group or benzyl group which is substituted or unsubstituted by halogen atom, C1-C6 alkoxy group, C1-C6 alkyl group, or cyano group; R2 is a hetero ring group selected from piperidinyl group, pyrolidinyl group, morpholinyl group and piperazinyl group which is substituted or unsubstituted by C1-C6 alkyl substituent; and n is 1 or 2, provided that a compound in which R2 is morpholinyl group when R1 is C1-C6 alkyl-substituted phenyl group is excluded.
