Compounds of the formula ##STR1## in which R.sub.1 and R.sub.2 independently of one another are substituted or unsubstituted aryl or hetero-aryl groups, R.sub.3 is hydrogen or lower alkyl and R.sub.4 is a substituted or unsubstituted aliphatic hydrocarbon radical, and their pharmaceutically usable salts. These compounds possess immunoregulatory, antithrombotic and antiinflammatory properties and can be used as active ingredients in medicaments. They are prepared, for example, by reacting compounds of the formulae ##STR2## in which one of the radicals X and Y is mercapto, which can be in the form of a salt, and the other is a radical replaceable by etherified mercapto, with one another.
公式为##STR1##的化合物,其中R.sub.1和R.sub.2分别是取代或未取代的芳基或杂环芳基,R.sub.3是氢或低碳烷基,R.sub.4是取代或未取代的脂肪烃基,以及它们的药用盐。这些化合物具有免疫调节、抗血栓和抗炎性能,并可用作药物的活性成分。例如,它们可通过将公式为##STR2##的化合物进行反应制备,其中X和Y中的一个基团是巯基,可以是盐的形式,另一个是可由醚化巯基取代的基团。
