Amphotericin B Associated with Triglyceride-rich Nanoemulsion: Stability Studies and in Vitro Antifungal Activity
Amphotericin B (AB) is the standard drug for invasive fungal infection therapy. It has a broad spectrum of activity and it is the best antifungal available against most yeasts and molds. Its therapeutic use, however, is limited by significant side effects, leading to a low therapeutic index when it is used as the traditional formulation (Fungizone®). Due to self-association, AB can form pores i...
متن کاملComparative 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...
متن کاملIn 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...
متن کاملIn vitro and in vivo antifungal activity of amphotericin B lipid complex: are phospholipases important?
Amphotericin B lipid complex for injection (ABLC) is a suspension of amphotericin B complexed with the lipids L-alpha-dimyristoylphosphatidylcholine (DMPC) and L-alpha-dimyristoylphosphatidylglycerol. ABLC is less toxic than amphotericin B deoxycholate (AmB-d), while it maintains the antifungal activity of AmB-d. Active amphotericin B can be released from ABLC by exogenously added (snake venom,...
متن کاملAmphotericin 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 ...
