Some research reports on antifungals have found greater efficacy with combinations of antifungal drugs that use different mechanisms of action the same process has been applied to other compounds in looking for ways to overcome fungal resistance. The echinocandin drugs anidulafungin, caspofungin, and micafungin are lipopeptides that target glucan synthase (a key enzyme involved in cell wall biosynthesis), 64 onishi j. Abstract: the echinocandins are a new class of antifungal lipopeptides for the treatment of serious nosocomial mycoses the three currently approved drugs, caspofungin, micafungin, and anidulafungin, were each discovered through the synthetic modification of echinocandin natural products obtained from fermentation. Echinocandins are nonribosomal lipopeptides produced by ascommycete fungi due to their strong inhibitory effect on fungal cell wall biosynthesis and lack of human toxicity, they have been developed to an important class of antifungal drugs.
