Chiral DNA gyrase inhibitors. 2. Asymmetric synthesis and biological activity of the enantiomers of 9-fluoro-3-methyl-10-(4-methyl-1-piperazinyl)-7-oxo-2,3-dihydro-7H-pyrido[1,2,3-de]-1,4-benzoxazine-6-carboxylic acid (ofloxacin)

A short and efficient synthesis, starting with (R)- and (S)-alaninol, of the two optical antipodes of the quinolone antimicrobial agent ofloxacin has been devised. Testing in vitro of the products against a range of bacteria and in an assay system incorporating purified DNA gyrase from different bacterial species demonstrates that the S-(-) enantiomer is substantially the more active.
已经设计了一种短而有效的合成方法,以氧氟沙星喹诺酮类抗菌剂的两种光学对映体为起始,从(R)-和(S)-丙氨醇开始合成。在体外测试产品对一系列细菌的影响,并在包含来自不同细菌物种的纯化DNA促旋酶的测定系统中进行测试,结果表明S-(-)对映异构体的活性更高。
