Some (alpha-hydrazinobenzyl)cephalosporins, I (R = Me, CH2OAc, Cl) and II (R = Me, CH2OAc), structurally related (formula; see text) to cephalexin, cephaloglycin, and cefaclor have been prepared and evaluated in vitro for their antimicrobial activity. The synthesis involves the condensation of the chloride hydrochloride III (R = H or Me) with the 7-aminocephem derivatives IV. The hydrazino compound
已经制备了一些(α-肼基苄基)头孢菌素I(R = Me,CH2OAc,Cl)和II(R = Me,CH2OAc),它们与头孢氨苄,头孢甘油和头孢克洛具有结构相关性(配方;见正文)因其抗菌活性。合成过程包括将氯化氢盐酸盐III(R = H或Me)与7-氨基头孢衍生物IV缩合。头孢克洛类似物肼化合物I(R = Cl),是该系列中活性最高的化合物。
