Reduction of Cell Membrane Toxicity of Amphotericin B Using Liposome System
리포좀계를 이용한 Amphotericin B의 세포막 독성 저하
Abstract
Lipsome system composed of egg phosphatidylcholine was employed to reduce the membrane toxicity of Amphotericin B(Amp. B). Liposomal Amp. B, which showed a free drug equivalent antibiotic effect on fungi, displayed a remarkable reduction of toxicity of the drug against the membrane of red blood cell than that of fungizone which has been used in clinical treatment, and it shows conspicuously lowered toxicity on red blood cells. However liposomal Amp. B which contains cholesterol as a component of liposome lowered the antibiotic effect and toxicity than that phosphatidylcholine liposome. This due to the affinity between Amp. B and cholesterol. In addition to this,
Amp. B의 세포막 독성을 낮추기 위하여 egg phosphatidylcholine를 사용한 리포좀계를 이용하였다. 리포좀에 포획 된 Amp.B는 Candida albicans에 대해 free drug보다 향상되거나 동일한 항생효과를 가지면서도 동시에 적혈구에 대한 세포막 독성은 현 저히 감소된 것으로 나타났다. 이러한 현상은 Ca
