specific compounds with chemical functionality in regions of the carbon skeleton that are not easily activated by conventional organic chemistry methods. In this work, Cladosporium antarcticum isolated from sediments of Glacier Collins in Antarctica was used to obtain novel drimane sesquiterpenoids alcohols with activity against Candida yeast from drimendiol and epidrimendiol. These compounds were produced
真菌生物转化是一种有吸引力的合成策略,可在碳骨架区域产生具有化学功能的高度特异性化合物,而这些区域不易被传统有机化学方法激活。在这项工作中,Cladosporium antarcticum从南极洲柯林斯冰川的沉积物中分离出来,用于从 drimendiol 和 epidrimendiol中获得具有抗念珠菌活性的新型 drimane 倍半萜醇。这些化合物是通过在甲醇中用 NaBH 4高产率还原何首乌二醛和isotadeonal制备的。Cladosporium antarcticum从 drimendiol 中产生两种主要产物,确定为 9α-hydroxydrimendiol ( 1, 41.4 mg, 19.4% 产率) 和 3β-hydroxydrimendiol ( 2 , 74.8 mg, 35% 产率),而表二醇的生物转化仅产生一种产物,9β-hydroxyepidrimendiol (
