New antifungal and less toxic zwitterionic derivatives of 26-membered polyene antibiotic – pimaricin containing N-benzyl and N-alkyl moieties and their molecular mechanism
Abstract N-derivatives of pimaricin (PIM) were synthesised as zwitterions or in a non-ionic form, influencing water solubility and toxicity in normal cells (HDF). The introduction of benzyl-O-aliphatic (15) and methylene-nitrophenol (7) moieties into the polyene resulted in high and broad-spectrum antifungal activities...
