<p>A novel carbostyril derivative and salt thereof represented by the formula (1), <CHEM> (wherein R is a group of the formula <CHEM> ((wherein R<1> is a C1-C3 alkoxy group)), a group of the formula <CHEM> ((wherein R<2> and R<3> are each, at the same time, a chlorine atom, a bromine atom; and R<4> is a hydrogen atom or a chlorine atom)), 2-methyl-3-nitrophenyl group, 3,5-dichlorophenyl group, or a group of the formula <CHEM> ((wherein R<5> is a chlorine atom or a bromine atom; and R<6> is a methyl group)); the carbon-carbon bond between 3- and 4-position in the carbostyril skeleton is a single or double bond). The novel carbostyril derivative and salt thereof represented by the formula (1) is useful agent for treating schizophrenia.</p> |
