Total syntheses of the title natural products, pseudopyronines A (1) and B (2), have been achieved using methyl β-oxo carboxylic ester starting materials. The natural products and a small set of structurally related compounds were evaluated for growth inhibitory activity against a range of pathogenic microorganisms and were found to exhibit good potency (IC50≥0.46 μg/mL) and selectivity towards Leishmania
使用甲基β-氧代羧酸酯原料已完成标题天然产物假吡喃酮A(1)和B(2)的总合成。天然产物和少量组结构上相关的化合物用于针对一系列病原微生物的生长抑制活性进行了评价,发现其显示出良好的效力(IC 50 ≥0.46微克/毫升),并选择性向杜氏利什曼原虫。几种化合物抑制了恶性疟原虫和结核分枝杆菌的重组脂肪酸生物合成酶,从而在寻找新的抗感染药时验证了这些靶标。
