The synthesis and biological evaluation of sixteen-membered macrolides possessing a 4-O-alkyl-α-L-cladinosyl moiety as the neutral sugar are described. The nine novel derivatives have been synthesized by glycosylation with 1-thio sugars. The most active derivative of them showed prolonged antibacterial activity in rat plasma in vitro and improved pharmacokinetics.
本文描述了具有4-O-烷基-α-L-纤维基中性糖部分的十六元大环内酯的合成与生物学评价。这九种新颖衍生物是通过与1-硫代糖的糖基化反应合成的。其中活性最强的衍生物在体外大鼠血浆中显示出延长的抗菌活性,并具有改善的药代动力学特性。
