ABSTRACT:
Carbostyril derivatives having antihistamic action and central nervous controlling action are useful as antihistamic agents or central nervous controlling agents. The derivatives are represented by the general formula, ##STR1## wherein R.sup.1 is a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, an alkenyl group having 2 to 4 carbon atoms, an alkynyl group having 2 to 4 carbon atoms or a phenylalkyl group having an alkylene group containing 1 to 4 carbon atoms; R.sup.2 is a hydrogen atom, an alkyl group having 1 to 4 carbon atoms or a phenyl group; R.sup.3 is a hydrogen atom, a hydroxy group, an alkyl group having 1 to 4 carbon atoms, an alkanolyoxy group having 1 to 4 carbon atoms or a 3,4,5-trimethoxybenzoyloxy group; R.sup.4 is a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; R.sup.5 is a cycloalkyl group having 3 to 8 carbon atoms, a phenyl group (which may have 1 to 3 substituted groups selected from the group consisting of halogen atoms, alkyl groups having 1 to 4 carbon atoms and alkoxy groups having 1 to 4 carbon atoms), an alkyl group having 1 to 4 carbon atoms (having one substituted group such as a hydroxy group, a phenyl group or an alkanoyloxy group having 1 to 4 carbon atoms), an alkanoyl group having 1 to 4 carbon atoms or benzoyl group; X is a halogen atom; n is 0, or an integer of 1 or 2; Q is an integer of 2 or 3, l and m are respectively an integer of 0 or 1-6, but the sum of l and m should not exceed 6; the carbon-carbon bond at the 3- and 4-positions in the carbostyril skeleton is a single or double bond; and the substituted position of the side chain of ##STR2## is any one of the 4-, 5-, 6-, 7- or 8-positions.
