To discover antifungal compounds with broad-spectrum and stable metabolism, a series of 2-(benzo[b]thiophen-2-yl)-4-phenyl-4,5-dihydrooxazole derivatives was designed and synthesized. Compounds A30-A34 exhibited excellent broad-spectrum antifungal activity against Candida albicans with MIC values in the range of 0.03–0.5 μg/mL, and against Cryptococcus neoformans and Aspergillus fumigatus with MIC
为发现广谱、稳定代谢的抗真菌化合物,设计合成了一系列2-(苯并[ b ]噻吩-2-基)-4-苯基-4,5-二氢恶唑衍生物。化合物A30-A34对白色念珠菌具有优异的广谱抗真菌活性,MIC 值在 0.03-0.5 μg /mL 范围内,对新型隐球菌和烟曲霉的 MIC 值在 0.25-2 μg / mL范围内. 此外,化合物A31和A33在体外人肝微粒体中表现出高代谢稳定性,半衰期分别为 80.5 分钟和 69.4 分钟。此外,化合物A31和A33对 CYP3A4 和 CYP2D6 显示出微弱的抑制作用或几乎没有抑制作用。SD大鼠的药代动力学评价表明,化合物A31具有适宜的药代动力学性质,值得进一步研究。
