  Semisynthetic Derivatives of Purpuromycin as Potential Topical Agents for Vaginal Infections

  摘要：

  Purpuromycin (1) is an antibiotic with a broad spectrum of antimicrobial activity, encompassing bacteria, fungi, and protozoa, particularly those involved in vaginal infections. With the aim of enhancing the solubility and reducing the serum binding, a chemical program of modifications was undertaken on the natural compound, and a new interesting series of derivatives at the naphthoquinone system was synthesized and evaluated as potential topical agents for vaginal infections. In particular three semisynthetic derivatives, 7'-amino (8a), 7'-methylamino (8b), 7'-ethylamino (8c), of 7'-demethoxypurpuromycin seemed to be the most promising. They were tested for in vitro activity against three of the most important vaginal pathogens and showed activity similar to that of purpuromycin against Candida isolates while they were significantly more active against Trichomonas vaginalis and Gardnerella vaginalis, which are cultured in media containing blood or serum. This is probably due to the fact that the activity of the derivatives is less antagonized by these supplements than that of purpuromycin.
