Amphotericin Introduction        

Amphotericin B is a polyene antifungal antibiotic produced by Streptomyces nodosus, with antifungal activity. Amphotericin B binds to ergosterol, an essential component of the fungal cell membrane, thereby causing depolarization of the membrane and altering cell membrane permeability. This leads to leakage of important intracellular components, cell rupture, and eventually cell death. This agent may also induce oxidative damage in fungal cells and has been reported to stimulate host immune cells.

Amfotericina b Usage And Synthesis

Chemical properties It is pale yellow to orange needle crystal or powder. It is insoluble in water, ethanol, but soluble in acidic DMF, DMSO, and slightly soluble in DMF, acidic or alkaline water-containing lower alcohol. It is almost odorless, almost tasteless, and easy to be damaged by the light, heat and acid.
Uses 1. The product has strong inhibitory effect on various kinds of fungal infection, such as Cryptococcus neoformans, dermatitis budding yeast, histoplasma capsulatum, sporothrix schenkii, white candida, mucor sp and Coccidioides immitis. The goods are the primary choice of drugs for treating deep fungal disease.
2. It is a kind of polyene antifungal drugs. This drug binds to the sterol located on the fungal cell membranes sterol, disrupting the membrane permeability, causing the leakage of bacteria intracellular potassium ion, nucleotides, amino acids and therefore playing bactericidal effect by disrupting the normal metabolism.
