The present invention describes novel cyclic diol derivatives represented by formula I and II: ##STR1## in which Y represents O, S, SO, SO.sub.2, (CH.sub.2).sub.m wherein m is zero or an integer of 1 to 5, or NR.sup.a group wherein R.sup.a is hydrogen, lower alkyl, lower alkoxycarbonyl, aryl, arylalkyl or acyl; R.sup.1 represents an alkyl or alkylcarbamoyl group; R.sup.2 represents a group having formula T--(CH.sub.2).sub.n --V (X.sup.-)q, wherein T refers to a simple covalent bond, a CO, PO.sub.3.sup.-, C(O)O, or CONR.sup.b group wherein R.sup.b is hydrogen, lower alkyl or acyl; n refers to an integer of from 1 to 10; V represents either (i) the group indicated by formula --.sup.+ NR.sup.5 R.sup.6 R.sup.7 wherein R.sup.5, R.sup.6 and R.sup.7 stands for identical or different lower alkyl group, or two or three of R.sup.5, R.sup.6 and R.sup.7 taken together with the adjacent nitrogen form heterocyclic ammonio group, or (ii) the group indicated by the formula ##STR2## wherein R.sup.8 represents lower alkyl group; q is one or zero; X.sup.- represents a pharmaceutically acceptable anion. These compounds are potent PAF antagonists and thus useful for the treatment of the diseases in which PAF is involved.
本发明描述了由公式I和II表示的新颖的环二醇衍生物:其中Y代表O、S、SO、SO.sub.2、(CH.sub.2).sub.m,其中m为零或1到5的整数,或NR.sup.a基团,其中R.sup.a为氢、较低的烷基、较低的烷氧羰基、芳基、芳基烷基或酰基;R.sup.1代表烷基或烷基羰胺基团;R.sup.2代表具有公式T--(CH.sub.2).sub.n--V(X.sup.-)q的基团,其中T指简单共价键,CO、PO.sub.3.sup.-、C(O)O或CONR.sup.b基团,其中R.sup.b为氢、较低的烷基或酰基;n为1到10的整数;V表示(i)由式--.sup.+NR.sup.5R.sup.6R.sup.7表示的基团,其中R.sup.5、R.sup.6和R.sup.7代表相同或不同的较低烷基基团,或R.sup.5、R.sup.6和R.sup.7中的两个或三个与相邻氮原子形成杂环氨基基团,或(ii)由式表示的基团##STR2##其中R.sup.8代表较低烷基基团;q为一或零;X.sup.-表示药学上可接受的负离子。这些化合物是有效的PAF拮抗剂,因此可用于治疗PAF参与的疾病。
