Abstract

The invention discloses a method for purifying a pseudomonas acid A, which comprises the following steps: 1) absorption: absorbing solution containing the pseudomonas acid A with resin; 2) desorption: desorbing the pseudomonas acid A from the resin in the step 1) by using a solvent to obtain a desorption solution containing the pseudomonas acid A; and 3) processing the desorption solution containing the pseudomonas acid A obtained by the step 2) to obtain the pseudomonas acid A. The recovery rate and purity of pseudomonas acid A purified by the method provided by the invention reach 79 percent and over 98 percent respectively. The method for purifying the pseudomonas acid A (mupirocin) by using resin of the invention has obvious advantages in aspects of ecology, environmental protection, economy and industrial large-scale production.

Description

technical field

[0001] The invention relates to a method for purifying pseudomonic acid A. Background technique

[0002] Fermentation with Pseudomonas strains can synthesize multiple chemical components of antibiotics mainly composed of Pseudomonic Acid A. Except for Pseudomonic Acid A, other components are named with letters B-D [E.B.Chain, G.Mellows, J. Chem. Soc. Perkin Trans I. 318 (1977); J.P. Clayton et al., Tetrahedron Lett., 21, 881 (1980); P. J. O. Hanlon, N. H. Rogers, J. Chem. Perkin Trans I. 2665 (1983)]. Pseudomonic acid A is an aminoacyltransaminase inhibitor antibiotic, which can specifically bind to the isoleucine transfer RNA synthetase of bacteria, thereby inhibiting the synthesis of isoleucine-containing proteins in bacteria; Gram-positive bacteria, including Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes, and metmoxicillin-resistant bacteria, have high medical value and have been clinically used for a long time.
