Abstract

Kinetic data on potassium release from and killing of Candida albicans by the four polyene antibiotics amphotericin B, amphotericin B methyl ester hydrochloride, nystatin, and nystatin methyl ester hydrochloride are presented. The nystatins were relatively more effective than the amphotericins in causing potassium release rather than killing. These data suggest that the aqueous channels or pores formed by the polyene antibiotics are not central to the lethal action of the drugs.

摘要

本文给出了四种多烯抗生素两性霉素B、两性霉素B甲酯盐酸盐、制霉菌素和制霉菌素甲酯盐酸盐从白色念珠菌释放钾以及杀死白色念珠菌的动力学数据。在引起钾释放而非杀死细胞方面,制霉菌素比两性霉素相对更有效。这些数据表明,多烯抗生素形成的水性通道或孔对于药物的致死作用并非关键因素。
