A diamine-platinum (IV) complex represented by the following formula (1): ##STR1## wherein R.sup.1 and R.sup.2 together represent R.sup.5 O--CH(CH.sub.2 NH.sub.2).sub.2 (R.sup.5 represents hydrogen, acetyl, trifluoroacetyl, benzoyl, cycloalkylcarbonyl or methanesulfonyl) or a C.sub.5-8 1,2-cycloalkanediamine; R.sup.3 and R.sup.4 each represents hydrogen or R.sup.6 CO-- (R.sup.6 represents alkyl, halogenoalkyl, cycloalkyl, aryl or aralkyl); and two X's together represent a malonic acid residue or glycolic acid residue which may have a substituent capable of coordinating to the platinum in formula (1) by an O,O-coordination or an N-acylamino acid residue coordinating to the platinum in formula (1) by an O,N-coordination; and a pharmaceutical composition comprising as an active ingredient the above-described diamine-platinum (IV) complex.

Platinum (IV) complex and pharmaceutical composition comprising the same

An arylamide derivative of formula (1), a salt thereof and a therapeutic agent for hyperlipemia which comprises the derivative or salt: ##STR1## wherein Ar represents a group ##STR2## a naphthyl group, a pyridinyl group, a furyl group, a thienyl group, a quinolyl group or an indolyl group; Y represents a group ##STR3## and Q represents --O-- or a single bond, Z represents an alkylene group, and R.sup.4 represents a hydroxyl group, an alkoxy group or a group --NH(CH.sub.2).sub.m COOH.

Piperazine substituted carboxylic acid derivatives for treating

An arylamide derivative of formula (1), a salt thereof and a therapeutic agent for hyperlipemia which comprises the derivative or salt: ##STR1## wherein Ar represents a group ##STR2## a naphthyl group, a pyridinyl group, a furyl group, a thienyl group, a quinolyl group or an indolyl group; Y represents a group ##STR3## and Q represents --O-- or a single bond, Z represents an alkylene group, and R.sup.4 represents a hydroxyl group, an alkoxy group or a group --NH(CH.sub.2).sub.m COOH, useful for the treatment and prevention of hyperlipemia due to their excellent cholesterol reducing action, triglyceride reducing action and high safety.
