Plasma protein binding of amphotericin B and pharmacokinetics of bound versus unbound amphotericin B after administration of intravenous liposomal amphotericin B (AmBisome) and amphotericin B deoxycholate.
Unilamellar liposomal amphotericin B (AmBisome) (liposomal AMB) reduces the toxicity of this antifungal drug. The unique composition of liposomal AMB stabilizes the liposomes, producing higher sustained drug levels in plasma and reducing renal and hepatic excretion. When liposomes release their drug payload, unbound, protein-bound, and liposomal drug pools may exist simultaneously in the body. ...
متن کاملHigh purity amphotericin B.
OBJECTIVES Amphotericin B (AmB) is a drug of choice for treatment of disseminated fungal infections, but its use is often associated with severe adverse effects. Our observation that generic formulations of AmB contain multiple polyene components led us to propose that removal of other polyenes would yield a high purity AmB (AmBHP) with an improved therapeutic index. METHODS To test that prem...
متن کاملTaming Amphotericin B.
A strategy is introduced for enhancing the cellular selectivity of Amphotericin B (AmB) and other classes of membrane-disrupting agents. This strategy involves attaching the agent to a molecular umbrella to minimize the disruptive power of aggregated forms. Based on this approach, AmB has been coupled to a molecular umbrella derived from one spermidine and two cholic acid molecules and found to...
متن کاملPhysico-chemical and microbiological comparison of nystatin, amphotericin A and amphotericin B, and structure of amphotericin A.
Two polyene antibiotics, nystatin and amphotericin A, were compared by physico-chemical and microbiological methods. The two antibiotics were found to have the same molecular weight, 926, by plasma desorption and electron-impact MS. However, 13C NMR spectrometry and HPLC studies indicated that the two molecules are different. The 200 MHz NMR studies indicated a chemical environment of 24 carbon...
متن کاملNeutrophil toxicity of amphotericin B.
The toxicity of amphotericin B (AmB) for neutrophils and the protective effect of serum cholesterol were investigated. Neutrophils were exposed in vitro to varying concentrations of AmB. As judged by trypan blue exclusion, neutrophil viability decreased by 40% (P < 0.001) within 30 min of incubation in sterol-free buffer containing 5 mug of AmB per ml. In the presence of 4 mg of cholesterol per...
