The present invention relates to compounds of the formula: ##STR1## and the pharmaceutically acceptable salts thereof, wherein Z can be: ##STR2## wherein R.sup.3 is alkyl having 1 to 6 carbon atoms and, when n is greater than 1, each R.sup.3 can be the same or different; and n is an integer from 1 to 3; R.sup.1 and R.sup.2 can each independently be hydrogen, straight or branched chain alkyl, or cycloalkyl having 3 to 8 carbon atoms which can optionally be substituted at one or more positions by alkyl of 1 to 6 carbon atoms; X is oxygen, sulfur, NR.sup.4, wherein R.sup.4 is hydrogen or alkyl having 1 to 4 carbon atoms, C.dbd.O, CHOH, or CH.sub.2 ; Y is hydrogen, alkoxy, halogen, alkyl, or hydroxy; and m is an integer from 0 to 3. The compounds are antagonists of platlet-activating factor (PAF).
本发明涉及以下式的化合物:##STR1##及其药学上可接受的盐,其中Z可以是:##STR2##其中R.sup.3是具有1至6个碳原子的烷基,当n大于1时,每个R.sup.3可以相同或不同;n是1至3之间的整数;R.sup.1和R.sup.2可以分别是氢、直链或支链烷基,或者是具有3至8个碳原子的环烷基,可以在一个或多个位置被1至6个碳原子的烷基取代;X是氧、硫、NR.sup.4,其中R.sup.4是氢或具有1至4个碳原子的烷基,C.dbd.O,CHOH或CH.sub.2;Y是氢、烷氧基、卤素、烷基或羟基;m是0至3之间的整数。这些化合物是血小板活化因子(PAF)的拮抗剂。
