Polyene antibiotics. IX. An improved method for the preparation of methyl esters of polyene antibiotics.

Ramesh C. Pandey, Kenneth L. Rinehart

Abstract

An improved general method for the preparation of methyl esters of polyene antibiotics is discussed. Using this method methyl esters of pimaricin, nystatin, eurocidin, hamycin, hamycins A and B, aureofungin, partricins A and B, candimycin, candicidin, and amphotericin B have been prepared and their physical properties are reported. The biological activities of hamycins A and B and their methyl esters are also described.
