A number of penicillins (2) have been synthesized from the α-hydrazinoarylacetic acids (4) via the activated chloride hydrochlorides (5) or via the mixed anhydride of the corresponding N2-benzyloxycarbonyl derivatives (6). The penicillins, 2b, e, j, show good activity against gram-positive and gram-negative bacteria and enhanced penicillinase resistance in comparison with ampicillin.
许多青霉素(2)是通过α-肼基芳基乙酸(4)与活性氯化物盐酸盐(5)或相应的N2-苄氧羰基衍生物的混合酸酐(6)合成的。青霉素2b、e、j对革兰氏阳性和革兰氏阴性细菌具有良好的活性,并且与氨苄西林相比,青霉素对青霉素酶的耐受性更强。
