Synthesis of 6(α,β)-aminocholestanols as ergosterol biosynthesis inhibitors
摘要:
Delta(7)-5-Desaturase catalyses one of the last steps in ergosterol biosynthesis in fungi. Moreover Delta 5-unsaturation is necessary for the sparking function. Synthesis of three pairs of C-6 epimeric cholestanol derivatives are described as potential growth inhibitors. Preliminary results suggest that 6 beta-aminocholestanol is a potent antifungal agent.
