The present invention relates to new N-acyl derivatives of amino acids. These derivatives correspond to the general formula I below: ##STR1## in which A represents a linear or branched, saturated hydrocarbon radical containing from 1 to 6 carbon atoms or a saturated ring containing 6 carbon atoms, X represents a --COOH radical, a --COOAlkyl radical (alkyl from C.sub.1 to C.sub.4), a hydrogen atom or a --CH.sub.3 group when Y is --COOH or --COOAlkyl, Y represents a --COOH radical, a --COOAlkyl radical (alkyl from C.sub.1 to C.sub.4), an --NH.sub.2 group, an --SH group, an --SCH.sub.3 group, a --NH--CH(.dbd.NH)--NH.sub.2 group, a substituted or unsubstituted phenyl group, an indolin-3-yl group or a 5-hydroxyindolin-3-yl group, and Q represents an optionally substituted aromatic ring or an optionally substituted heterocycle containing 1 or 2 nitrogen atoms. Drugs having an antiallergic action.
本发明涉及新的氨基酸N-酰基衍生物,这些衍生物符合以下通式I:##STR1## 其中,A代表一个含有1至6个碳原子的直链或支链饱和烃基或一个含有6个碳原子的饱和环,X代表一个--COOH基团,一个--COOAlkyl基团(Alkyl为C.sub.1至C.sub.4的烷基),一个氢原子,或者当Y为--COOH或--COOAlkyl时,X代表一个--CH.sub.3基团,Y代表一个--COOH基团,一个--COOAlkyl基团(Alkyl为C.sub.1至C.sub.4的烷基),一个--NH.sub.2基团,一个--SH基团,一个--SCH.sub.3基团,一个--NH--CH(.dbd.NH)--NH.sub.2基团,一个取代或未取代的苯基,一个吲哚啉-3-基团或一个5-羟基吲哚啉-3-基团,Q代表一个可选地取代的芳香环或一个含有1或2个氮原子的可选地取代的杂环。本发明的药物具有抗过敏作用。
