Compounds of formula (I): ##STR1## (wherein: l is 2-4; A and B are oxygen or sulfur; one of R.sup.1 and R.sup.2 represents a long chain alkyl, alkylcarbamoyl or aliphatic acyl group and the other of R.sup.1 and R.sup.2 represents a group of formula (III) or (II.sub.f): ##STR2## in which E represents a single bond, a bivalent heterocyclic group or a group of formula --CO--, --COO-- or --CONR.sup.6 --, where R.sup.6 is hydrogen or an imino-protecting group; m is 0-3; n is 0-10; q is 0 or 1; R.sup.4 is optionally protected hydroxy, mercapto group or carboxy; Q is an amino or nitrogen-containing heterocyclic group; R.sub.f.sup.4 R.sub.f.sup.5 and R.sub.f.sup.6 are independently selected from the group consisting of hydrogen atoms and C.sub.1 -C.sub.6 alkyl groups, or R.sub.f.sup.4 and R.sub.f.sup.5 or R.sub.f.sup.4, R.sub.f.sup.5 and R.sub.f.sup.6, together with the nitrogen atom to which they are attached, form a heterocyclic ring) are PAF antagonists which may be used to treat asthma, hypotension, inflammation and shock. They may be prepared by reacting the corresponding compound having a haloalkyl phosphate ester or alkylenephosphate ester group in place of the ammonioalkyl phosphate ester group with an appropriate amine.
公式(I)的化合物:其中:l为2-4;A和B为氧或硫;R.sup.1和R.sup.2中的一个代表长链烷基、烷基羰胺或脂肪酰基,另一个代表公式(III)或(II.sub.f)的基团:其中E代表单键、二价杂环基团或公式--CO--、--COO--或--CONR.sup.6--的基团,其中R.sup.6为氢或亚胺保护基;m为0-3;n为0-10;q为0或1;R.sup.4为可选择的保护羟基、巯基或羧基;Q为氨基或含氮杂环基团;R.sub.f.sup.4、R.sub.f.sup.5和R.sub.f.sup.6分别从氢原子和C.sub.1-C.sub.6烷基组成的群中独立选择,或R.sub.f.sup.4和R.sub.f.sup.5或R.sub.f.sup.4、R.sub.f.sup.5和R.sub.f.sup.6与它们连接的氮原子一起形成杂环环)是可用于治疗哮喘、低血压、炎症和休克的PAF拮抗剂。它们可以通过将具有卤代烷基磷酸酯或烷基磷酸酯基团代替氨基磷酸酯基团的相应化合物与适当的胺反应而制备。
