  Scaffold hopping of sampangine: Discovery of potent antifungal lead compound against Aspergillus fumigatus and Cryptococcus neoformans

  摘要：

  Discovery of novel antifungal agents against Aspergillus fumigatus and Cryptococcus neoformans remains a significant challenge in current antifungal therapy. Herein the antifungal natural product sampangine was used as the lead compound for novel antifungal drug discovery. A series of D-ring scaffold hopping derivatives were designed and synthesized to improve antifungal activity and water solubility. Among them, the thiophene derivative S2 showed broad-spectrum antifungal activity, particularly for Aspergillus fumigatus and Cryptococcus neoformans. Moreover, compound S2 also revealed better water solubility than sampangine, which represents a promising antifungal lead compound for further structural optimization.
