A derivative of 2-methylenepropane-1,3-diol of the general formula I ##STR1## where O--A.sup.1 and O--A.sup.2, which can be the same or different, each represents O, O--C(O), O--C(O)NH, O--C(S)NH or O--C(O)O, R.sup.1 represents an alkyl or alkenyl group of 10-22 carbon atoms, n is an integer from 1 to 11, B.sup.+ represents a quaternary ammonium group, either N.sup.+ R.sup.4 R.sup.5 R.sup.6, or N.sup.+ (Het), where R.sup.4, R.sup.5 and R.sup.6 are similar or different alkyl groups of 1-4 carbon atoms, or two or all of R.sup.4, R.sup.5 and R.sup.6 may be incorporated into a cyclic or bicyclic structure, which may contain additional hetero atoms; X.sup.- means the anion of a pharmceutically acceptable inorganic or organic acid; and R.sup.2 and R.sup.3 are the same or different, and represent hydrogen or alkl groups of 1-4 carbon atoms. The present compounds have been shown to possess a PAF antagonistic effect and an inhibitory effect on the growth of tumor cells, and are thus valuable in the human and veterinary practice as platelet aggregation inhibitors, anti-thrombotic agents, anti-asthmatic agents, anti-allergic agents, anti-inflammatory agents, anti-hypotensive agents, anti-ulcer agents, anti-psoriatic agents, anti-graft rejection agents, anti-conception agents and anti-tumor agents.
该化合物的普遍式I为:##STR1## 其中O-A.sup.1和O-A.sup.2可以相同也可以不同,每个代表O,O-C(O),O-C(O)NH,O-C(S)NH或O-C(O)O,R.sup.1代表10-22个碳原子的烷基或烯基,n为1至11的整数,B.sup.+代表季铵基,可以是N.sup.+R.sup.4R.sup.5R.sup.6或N.sup.+(Het),其中R.sup.4,R.sup.5和R.sup.6是相似或不同的1-4个碳原子的烷基,或者其中两个或全部可以并入环状或双环结构中,其中可能含有其他杂原子;X.sup.-表示药学上可接受的无机或有机酸的阴离子;R.sup.2和R.sup.3相同或不同,代表氢或1-4个碳原子的烷基。这些化合物已被证明具有PAF拮抗作用和抑制肿瘤细胞生长的作用,在人类和兽医实践中非常有价值,可用作血小板聚集抑制剂,抗血栓剂,抗哮喘剂,抗过敏剂,抗炎剂,抗低血压剂,抗溃疡剂,抗银屑病剂,抗移植排斥剂,抗避孕剂和抗肿瘤剂。
