Molecular Umbrellas Modulate the Selective Toxicity of Polyene Macrolide Antifungals

Abstract

Antifungal polyene macrolide antibiotics Amphotericin B (AmB) and Nystatin (NYS) were conjugated through the ω-amino acid linkers with diwalled “molecular umbrellas” composed of spermidine-linked deoxycholic or cholic acids. The presence of “umbrella” substituents modulated biological properties of the antibiotics, especially their selective toxicity. Some of the AmB-umbrella conjugates demonstrated antifungal in vitro activity comparable to that of the mother antibiotic but diminished mammalian toxicity, especially the hemolytic activity. In contrast, antifungal in vitro activity of NYS-umbrella conjugates was strongly reduced and all these conjugates demonstrated poorer than NYS selective toxicity. No correlation between the aggregation state and hemolytic activity of the novel conjugates was found.
