Glycerol derivatives of the general formula:
(wherein R1 represents an alkyl group of 6 to 22 carbon atoms or an alkyl group of 2 to 5 carbon atoms substituted by a phenyl group, A represents a single bond or an oxygene atom, R2 represents an alkyl group of 1 to 20 carbon atoms, an alkenyl group of 2 to 20 carbon atoms when A represents a single bond or an alkenyl group of 3 to 20 carbon atoms when A represents an oxygene atom, B represents an oxygene atom or a carbonyloxy group (i.e. -O-CO- group; with the proviso that in which a carbonyl group is attached to R3 and an oxa-group is attached to a carbon atom at the third position of the glycerol skeleton), R3 represents an alkylene group of 1 to 12 carbon atoms and R4 represents a group of the formula :
(in which R5 represents an alkyl group of 1 to 6 carbon atoms or a phenyl group, R6 represents an alkyl group of 1 to 6 carbon atoms and represents an anion of an acid; with the proviso that when plural R6 are attached to a nitrogen atom, they may be same or different to each other)), and acid addition salt thereof, possess antagonistic effect on PAF, hypotensive effect like PAF, inhibitory effect on phospholipase and inhibitory effect on growth of tumour cell or induction of differentiation, and are, therefore, useful as a platelet aggregation inhibitor, anti-asthmatic agent, anti-allergic agent, anti-inflammatory agent, hypotensive agent and anti-tumour agent for mammals.
通式如下的甘油衍生物
(其中 R1 代表 6 至 22 个碳原子的烷基或被苯基取代的 2 至 5 个碳原子的烷基,A 代表单键或烯氧原子,R2 代表 1 至 20 个碳原子的烷基,当 A 代表单键时代表 2 至 20 个碳原子的烯基,或当 A 代表烯氧原子时代表 3 至 20 个碳原子的烯基,B 代表烯氧原子或碳酰氧基团(即 -O-CO- 基团);但其中羰基连接到 R3,而烯氧基团连接到第三位的碳原子上。R3代表1至12个碳原子的亚烷基,R4代表式:
(其中 R5 代表 1-6 个碳原子的烷基或苯基,R6 代表 1-6 个碳原子的烷基并代表酸的阴离子;但当多个 R6 连接到一个氮原子上时,它们可以彼此相同或不同))及其酸加成盐,具有拮抗 PAF 的作用,与 PAF 类似的降血压作用、因此,可用作哺乳动物的血小板聚集抑制剂、抗哮喘剂、抗过敏剂、抗炎剂、降血压剂和抗肿瘤剂。
