Abstract
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.
