520 3 |a Pimaricin is an important antifungal antibiotic for antifungal therapy and prevention of mould contamination in the food industry. In this study, three new pimaricin derivatives, 12-decarboxy-12-methyl pimaricin (1), 4,5-desepoxy-12-decarboxy-12-methyl pimaricin (2), and 2-hydro-3-hydroxy-4,5-desepoxy-12-decarboxy-12-methyl pimaricin (3), were generated through the inactivation of P450 monooxygenase gene scnG in Streptomyces chattanoogensis L10. Compared with pimaricin, 1 displayed a twofold increase in antifungal activity against Candida albicans ATCC 14053 and a 4.5-fold decrease in cytotoxicity with erythrocytes, and 2 had comparable antifungal activity and reduced cytotoxicity, whereas 3 showed nearly no antifungal and hemolytic activities. Genetic and biochemical analyses proved that 1 is converted from 2 by P450 monooxygenase ScnD. Therefore, the overexpression of scnD in scnG-null strain eliminated the accumulation of 2 and improved the yield of 1 by 20%. Conversely, scnG/scnD double mutation abolished the production of 1 and improved the yield of 2 to 2.3-fold. These results indicate that the pimaricin derivatives with improved pharmacological properties obtained by genetic engineering can be further developed into antifungal agents for potential clinical application.
