To discover potential sterol 14α-demethylase (CYP51) inhibitors, thirty-four unreported 4H-pyrano[3,2-c]pyridine derivatives were designed and synthesized. The assay results indicated that most compounds displayed significant fungicidal activity against Sclerotinia sclerotiorum, Colletotrichum lagenarium, Botrytis cinerea, Penicillium digitatum, and Fusarium oxysporum at 16 μg/mL. The half maximal
为了发现潜在的甾醇 14α-去甲基酶 (CYP51) 抑制剂,设计并合成了 34 种未报道的 4 H-吡喃并[3,2- c ]吡啶衍生物。测定结果表明,大多数化合物在 16 μg/mL 浓度下对核盘菌、胶状炭疽菌、灰葡萄孢、指状青霉和尖孢镰刀菌表现出显着的杀菌活性。化合物7a 、 7b和7f对抗灰霉病的半数最大有效浓度(EC 50 )值分别为0.326、0.530和0.610。即,它们比氧环唑具有更好的抗真菌活性(EC 50 = 0.670 μg/mL)。同时,它们对CYP51的半数抑制浓度(IC 50 )值分别为0.377、0.611和0.748 μg/mL,这表明它们也比氧环唑(IC 50 = 0.802 μg/mL)具有更好的抑制活性。蛋白质的荧光猝灭测试表明7a和7b具有与氧环唑相似的猝灭模式。分子动力学模拟表明7a和氧环唑与CYP51的结合自由能分别为-35.4和-27.6 kcal/mol。
