In an effort to find a new oral cephalosporin with well-balanced antibacterial spectrum, good oral absorbability and long plasma half-life, a series of oxyimino aminothiazolyl 3-[(E)- or (Z)-N-substituted carbamoyloxy]propenyl cephems was synthesized and evaluated for antibacterial activity and oral absorbability. The substituents of the carbamoyloxy group affected their in vitro activity and bioavailability
为了寻找一种具有良好平衡的抗菌谱,良好的口服吸收性和长血浆半衰期的新型口服头孢菌素,一系列氧亚氨基氨基噻唑基3-[(E)-或(Z)-N-取代的氨基甲酰氧基]丙烯基头孢烯合成并评估其抗菌活性和口服吸收性。氨基甲酰氧基的取代基在C-4位口服新戊酰氧基甲基酯后会影响其体外活性和生物利用度。在C-3位上具有N,N-二甲基氨基甲酰氧基部分的化合物显示出良好的口服吸收和均衡的抗菌活性。在该报告中,描述了3-(N-取代的氨基甲酰氧基)-丙烯基头孢烯的结构-活性关系和结构-口服吸收性关系。
