Some beta-aminoxypropionyl penicillins (3) and cephalosporins (4 and 5), planned on the basis of the hypothesis that the (methyleneaminoxy)methyl group (greater than C = NOCH2) could be a "bioisoster" of either aryls or other aromatic groups, were synthesized and assayed for their antimicrobial properties. Compounds 3-5, tested on Gram-positive and Gram-negative bacteria, both sensitive to enzyme inactivation
一些β-氨基羟丙酰青霉素(3)和头孢菌素(4和5)是基于以下假设而计划的:(亚甲基氨基氧)甲基(大于C = NOCH2)可能是芳基或其他芳香基团的“生物等排体” ,合成,并分析其抗菌性能。在革兰氏阳性和革兰氏阴性细菌上测试的化合物3-5,对酶失活均敏感,否则对活性的趋势与作为对照的相应的苯乙酰胺基衍生物没有明显的不同。
