l-amino alcohol derivatives exhibited high antifungal activity, but the metabolic stability of human liver microsomes in vitro was poor, and the half-life of optimal compound 5 was less than 5 min. To improve the metabolic properties of the compounds, the scaffold hopping strategy was adopted and a series of antifungal compounds with a dihydrooxazole scaffold was designed and synthesized. Compounds
l-氨基醇衍生物具有较高的抗真菌活性,但人肝微粒体体外代谢稳定性较差,最佳化合物5的半衰期小于5 min。为改善化合物的代谢特性,采用支架跳跃策略,设计合成了一系列具有二氢恶唑支架的抗真菌化合物。二氢恶唑环上被4-苯基取代的化合物A33-A38对白色念珠菌、热带念珠菌和克氏念珠菌表现出优异的抗真菌活性,MIC值在0.03~0.25 μ之间。克/毫升。此外,化合物A33和A34在体外人肝微粒体中的代谢稳定性显着提高,半衰期分别大于145 min和59.1 min。此外,SD大鼠的药代动力学研究表明,A33具有良好的药代动力学特性,生物利用度为77.69%,半衰期(静脉给药)为9.35 h,表明A33值得进一步研究。
