toward the discovery of chiral antifungal amides turned to the optimization of their polar regions with 2-(2-oxazolinyl)aniline as a known pharmacophore. Scaffold hopping and bioactivity-guided convergent synthesis enabled the identification of promising antifungal categories. Fine tuning of the substituents and chirality furnished seven amides (1s, 1t, 2d, 2h, 2j, 3k, and 2l) as antifungal candidates
受成熟的琥珀酸脱氢酶抑制剂(SDHIs)的启发,我们对发现手性抗真菌酰胺的不懈努力转向使用2-(2-恶唑啉基)苯胺作为已知药效团优化其极性区域。脚手架跳跃和生物活性指导的收敛合成使有希望的抗真菌类别的鉴定。取代基和手性的精细调节提供了7种酰胺(1s,1t,2d,2h,2j,3k和2l)作为抗真菌候选物,其EC 50值低于5 mg / L。进行了无环酸手性酰胺作为SDHIs的首次研究,选择2d作为灰葡萄孢的有希望的候选物,其在50 mg / L时的预防效果高达93.9%,优于Boscalid。针对化合物2d及其非对映异构体,模拟了具有不同构型的化合物之间的不同结合模型。合成可及性和成本效益的优势突出了化合物2d作为已知SDHI杀菌剂的良好替代品的实际潜力。
