title: [Synthesis and biological activity of 7-(2-nitroimidazoles and 7-(2-aminoimidazole) methyleneamino cephalosporin and their derivatives].
abstract: The synthesis of 7-[[(1-methyl-2-nitro-1H-imidazol-5-yl)methylene]amino] and 7-[[(2-amino-1-methyl-1H-imidazol-5-yl)methyle-ne]amino]cephalosporanic acids and of some derivatives is described. Their physico-chemical characteristics are reported. The compounds show no appreciable antibacterial activity in vitro. They show no synergy with cephaloridine against Enterobacter cloacae 214 (producer of class I beta-lactamase) and therefore have no anti-beta-lactamase activity.
