A method of treating a PAF-mediated pathology or for treating or preventing psoriasis, nephritis, asthma, inflammation or shock by administering an effective amount of a PAF antagonist of the formula ##STR1## wherein R.sup.1 and R.sup.2 are each --R.sup.5, --CH.dbd.CH--R.sup.5 or --C.tbd.C--R.sup.5 ; R.sup.5 is an unsubstituted or substituted C.sub.6 -C.sub.14 carbocyclic aryl of an aromatic heterocyclic having from 5 to 14 ring atoms, of which from 1 to 5 are hetero-atoms selected from the group consisting of nitrogen, oxygen and sulfur, the heterocyclic group being unsubstituted or substituted; R.sup.3 is hydrogen, a C.sub.1 -C.sub.6 alkyl, cyano, or --R.sup.5 ; X is oxygen or sulfur; A is a 1,4-piperazin-1,4-diyl or a 1,4-homopiperazin-1,4-diyl; B is a C.sub.1 -C.sub.6 alkylene, carbonyl, thiocarbonyl, sulfinyl or sulfonyl; and R.sup.4 is an unsubstituted or substituted phenyl group.
