Chemical and biological stability of polyene macrolides
PublicationThe polyene macrolide antibiotics have been used in an-tifungal therapy since first o f them were discovered in 1950's. Up to now, four polyene macrolides are being used in medical practice, namely amphotericin B, nystatin, candi-cidin and pimaricin.The antifungal activity and mode of ac-tion of polyene macrolides is determined by their structure, chemical and physical properties.The main fragment of polyene...

Molecular Umbrellas Modulate the Selective Toxicity of Polyene Macrolide Antifungals
PublicationAntifungal 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...

Modulation of polyene antibiotics self-association by ions from the hofmeister series
PublicationZbadano wpływ soli z serii hofmeistera na zjawisko samoasocjacji antybiotyku polienowego amfoterycyny B i jego pochodnych. Wykazano, że sole te zmieniając właściwości wody, wpływają istotnie na strukturę roztworów tych antybiotyków. Sole kosmotropowe zmniejszają rozpuszczalność związków, chaotropowe dają efekt przeciwny.
