title: Bioconversion of 19-deformyl-5-O-desosaminyl tylonolide to 19-deformyl-4'-deoxydesmycosin (TMC-016).
abstract: Bioconversion of 19-deformyl-5-O-desosaminyl tylonolide (1) to 19-deformyl-4'-deoxydesmycosin (3) was performed by using a mycinamicin-producing Micromonospora species. Compound 1 at low concentrations was completely converted to compound 3, however, the conversion to compound 3 was suppressed at high concentrations and 19-deformyl-4'-deoxy-2", 3'-di-O-demethyl-desmycosin (2), an intermediate leading to compound 3 accumulated.
