The (E)-isomer (11) of FK027 was synthesized by two methods. The effect of the configuration of the oxime in the 7-acyl side chain of FK027 (1) on the antimicrobial activity and oral absorbability in rats was investigated. Both FK027 (1) and its (E)-isomer (11) showed appreciable oral absorbability regardless of the configuration of the oxime.
通过两种方法合成了 FK027 的(E)-异构体(11)。研究了 FK027 (1) 7-酰基侧链中肟的构型对其抗菌活性和大鼠口服吸收性的影响。无论肟的构型如何,FK027(1)及其(E)-异构体(11)都表现出明显的口服吸收性。
