    摘要: The invention provides crystalline minocycline base. In particular, three crystalline polymorphic forms, designated Form I, Form II and Form III, of minocycline base are provided. These are characterized by XRD and IR data. Processes for preparing the new polymorphic forms are also provided. For example, Form I is prepared by dissolving and/or suspending amorphous minocycline base in an organic solvent chosen from ethers followed by crystallization from the mixture.

    摘要: The present invention relates to methods for synthesizing macrolide compounds which are known to have antibacterial activity, and are useful in the therapy of bacterial infections in mammals. More specifically, the invention relates to methods for synthesizing the macrolide antibiotic, gamithromycin utilizing a novel configuration of catalysts, chemical structures, and/or methods. An embodiment of the present invention may include allowing multiple chemical reactions to proceed without the isolation of chemical intermediates. Thus, multiple reactions may occur in one reaction vessel allowing for a considerable decrease in the cycle-time. The present invention also provides a novel method for inhibiting degradation while isolating a structure of a pharmaceutical composition.

    摘要: A process for the preparation of high purity flumethasone in high yield involves C3 protecting 9,11&bgr;-epoxy-17&agr;,21-dihydroxy-16&agr;-methylpregna-1,4-diene-3,20-dione,21-acetate, fluorinating at 6&agr;, removing the C3 protecting group, fluorinating the 9,11-epoxy group. The resulting flumethasone 21-acetate is treated with the methanolic potassium hydroxide in the presence of an oxidation agent, causing a simultaneous hydrolyzation and degradative oxidation, resulting in the formation of 6&agr;,9&agr;-difluoro-11&bgr;,17&agr;-dihydroxy-16&agr;-methyl-17&bgr;-carboxy-androsta-1,4-diene-3-one in high yield. Flumethasone 21-acetate is alternatively hydrolyzed to yield flumethasone free alcohol.
