4-dihydro-7-(3-hydroxypyrrolidin-1-yl)-4-oxoquinoline-3-carboxylic acid (10) were prepared. One of the isomer, 7-[(3S)-hydroxypyrrolidin-1-yl] derivative 8, was about 4 times more potent in vitro than the other, 7-[(3R)-hydroxypyrrolidin-1-yl] derivative 4, and approximately two times more active than the racemate, 7-[(3RS)-hydroxypyrrolidine-1-yl] derivative 10.
制备了1-乙基-6,8-二氟-1,4-二氢-7-(3-羟基吡咯烷-1-基)-4-氧代喹啉-3-羧酸的两种旋光异构体(10)。一种异构体7-[((3 S)-羟基吡咯烷-1-基]衍生物8在体外的效价比另一种异构体7-[((3R)-羟基吡咯烷-1-基]衍生物4的效价高约4倍。,并且其活性是外消旋物7-[((3 RS)-羟基吡咯烷-1-基]衍生物10的大约两倍。
