Lipid derivatives represented by the formula: ##STR1## wherein R.sub.1 is alkyl or alkylcarbamoyl; R.sub.2 is lower alkyloxy, lower alkylcarbamoyloxy, lower alkylcarbonylamino, lower alkyloxycarbonylamino, lower alkylureido, lower alkyloxymethyl, lower alkylcarbonylmethyl, cyanomethyl, heterocyclic group, or he0 terocyclyloxy; R.sub.2 ' is hydrogen or R.sub.2 and R.sub.2 ' taken together form --O(CH.sub.2).sub.m -- wherein m is an integer of 1 to 5; R.sub.3, R.sub.4, and R.sub.5 each is hydrogen or lower alkyl or two or three of R.sub.3, R.sub.4, and R.sub.5 taken together with the adjacent nitrogen atom form cyclic ammonio; R.sub.6 is hydrogen or lower alkylcarbonyl; X.sup.- is a counter anion; Y is oxygen or sulfur; and n is an integer of 1 to 10, being useful as PAF antagonists, e.g., as antithrombotic, antivasoconstricting, antibronchoconstricting agent or antitumor agent.
该文本描述的是脂质衍生物的化学式,其中R1为烷基或烷基氨基甲酰基;R2为低碳基氧基、低碳基氨基甲酰氧基、低碳基羧酰胺基、低碳基氧羧酰胺基、低碳基脲基、低碳基氧甲基、低碳基羧甲基、氰基甲基、杂环基或杂环氧基;R2'为氢或R2和R2'组成--O(CH2)m--,其中m为1到5的整数;R3、R4和R5每个为氢或低碳基,或R3、R4和R5中的两个或三个与相邻的氮原子形成环状铵;R6为氢或低碳基甲酰基;X-为计数阴离子;Y为氧或硫;n为1到10的整数。这些化合物可用作PAF拮抗剂,例如作为抗血栓、抗血管收缩、抗支气管收缩剂或抗肿瘤剂。
