Protective and antifungal properties of Nanodisk-Amphotericin B over commercially available Amphotericin B☆

Objective Amphotericin B (AMB), a potent antifungal agent, has been employed as topical and systemic therapy for sinonasal fungal infections. A novel formulation of nanodisc (ND) containing super aggregated AMB (ND-AMB) for the treatment of fungal infections has been recently developed to provide greater protection from AMB toxicity than current, clinically approved lipid-based formulations. Th...

Amphotericin B-silver hybrid nanoparticles: synthesis, properties and antifungal activity.

UNLABELLED High antifungal activity is reported, in comparison with commercially available products, of a novel hybrid system based on silver nanoparticles synthesized using a popular antifungal macrocyclic polyene amphotericin B (AmB) acting both as a reducing and stabilizing/capping agent. The synthesis reaction proceeds in an alkaline environment which prevents aggregation of AmB itself and ...

Amphotericin B induces interdigitation of apolipoprotein stabilized nanodisk bilayers.

Amphotericin B nanodisks (AMB-ND) are ternary complexes of AMB, phospholipid and apolipoprotein organized as discrete nanometer scale disk-shaped bilayers. In gel filtration chromatography experiments, empty ND lacking AMB elute as a single population of particles with a molecular weight in the range of 200 kDa. AMB-ND formulated at a 4:1 phospholipid:AMB weight ratio separated into two peaks. ...

In vitro antifungal activities of amphotericin B and liposome-encapsulated amphotericin B.

The in vitro activities of liposome-encapsulated amphotericin B and free amphotericin B against Candida albicans 336 were comparable. Amphotericin B concentrations 12-fold and greater than 50-fold higher were required to kill the same organism when cholesterol and ergosterol were incorporated into the liposomes. The addition of cholesterol to liposomes caused a significant increase in the minim...

Comparative in vitro antifungal activity of amphotericin B and amphotericin B methyl ester.

The in vitro antifungal activity of amphotericin B methyl ester (AME), a water-soluble derivative of amphotericin B, was compared to that of the parent compound against a variety of pathogenic and potentially pathogenic fungi. AME has a significant antifungal activity, but the activity of AME was slightly lower than that of amphotericin B. Among the yeast-like organisms, only the yeast cells of...
