As analogues of D-cycloserine, the part structure of penicillin and D-D carboxypeptidase substrate of peptidoglycan of bacterial cell wall, D-alanine derivatives and their stereoisomers and D-alanyl-D-alanine derivatives and their stereoisomers (R1-Ala-R2, R1-Ala-Ala-R2 : R1=Z, H ; R2=NHNH2, NHCH3, NHCH2CH2OH) were synthesized. All compounds obtained did not show any antibacterial activity against Staphylococcus aureus, Sarcina lutea, Pseudomonas aeruginosa and Escherichia coli.
作为 D-环丝氨酸(青霉素的部分结构和细菌细胞壁肽聚糖的 D-D 羧肽酶底物)的类似物,合成了 D-丙氨酸衍生物及其立体异构体和 D-丙氨酰-D-丙氨酸衍生物及其立体异构体(R1-Ala-R2、R1-Ala-Ala-R2:R1=Z、H;R2=NHNH2、NHCH3、NHCH2CH2OH)。所有化合物对金黄色葡萄球菌、沙门氏菌、绿脓杆菌和大肠杆菌均无抗菌活性。
