, (2008/06/13)
Novel trisubstituted piperazine compounds of the formula (I): wherein A is an optionally substituted phenyl group, an optionally substituted condensed polycyclic hydrocarbon group, an optionally substituted hetero-cyclic group or a styryl group of the formula:, Ar - CR4 = CR5 - wherein Ar is an optionally substituted phenyl group, and R4 and R5 are independently hydrogen or a lower alkyl group, X is methylene group, carbonyl group or thiocarbonyl group, G is a group of the formula:, nZ-R6 wherein n is an integer of 0 to 2, Z is a chemical bond, O, S, SO, SO2, CO, COO, CONR7 or NR7 (wherein R7 is hydrogen, a lower alkyl group, a lower haloalkyl group, a lower alkenyl group or a lower alkoxycarbonyl group), and R6 is hydrogen, a lower alkyl group, a lower haloalkyl group or a lower alkenyl group, provided that, when n is 0 and Z is chemical bond, R6 is not hydrogen or a lower alkyl group, and R1, R2 and R3 are independently a lower alkyl group, and salts thereof, are useful as a platelet activating factor antagonist.
