Complexes of widely clinically used polyene antibiotics (amphotericin B, nystatin A1 and natamycin) with a modern Taunit nanoadsorbent were obtained for the first time and their antifugal activities were studied. It was established that the Taunit-nystatin A₁ complex possesses the antifugal activity against Aspergillus niger, whereas the Taunit-natamycin complex is active against Aspergillus niger and Candida albicans. The Taunit-amphotericin B complex failed to exhibit the activity against these test organisms. Possible mechanisms of the obtained complexes functioning are discussed.

Key words:  amphotericin B,  antifungal activity,  Aspergillus niger,  Candida albicans,  carbon nanotubes,  mechanism of action,  multiwalled carbon nanotubes of Taunit type,  natamycin,  nystatin A₁.
