A number of amino acid derivatives of DL-Zra/w-epoxysuccinic acid, with a general formula of R1O-ES-AA-OR2 (ES, DL-trans-epoxysuccinyl group; AA, amino acid residue) were newly synthesized and used for the study of structure-activity relationships of papain inhibition. Branched-alkyl amino acids, such as Leu, He and Val, as AA and hydrogen or an alkyl group substituted with a phenyl or cycloalkyl group as R1 were desirable for activity, respectively. However, R2 or the optical activities of ES and AA not so much influenced on the activity.
一些DL-Zra/w-环氧琥珀酸氨基酸衍生物被新合成并用于木瓜蛋白酶抑制的结构-活性关系研究。通式为R1O-ES-AA-OR2(ES,DL-反式环氧琥珀酰基团;AA,氨基酸残基)。AA为支链烷基氨基酸,如Leu、He和Val,R1为氢或被苯基或环烷基取代的烷基,这类衍生物具有较好的活性。但R2或ES和AA的光学活性对活性的影响不大。
