Oxazolidinone combinatorial libraries, compositions and methods of preparation

Abstract

Oxazolidinones and methods for their synthesis are provided. Also provided are combinatorial libraries comprising oxazolidinones, and methods to prepare the libraries. Further provided are methods of making biologically active oxazolidinones as well as pharmaceutically acceptable compositions comprising the oxazolidinones. The methods of library preparation include the attachment of oxazolidinones to a solid support. The methods of compound preparation in one embodiment involve the reaction of an iminophosphorane with a carbonyl containing polymeric support.

Description

FIELD OF THE INVENTION The present invention is directed to oxazolidinones; oxazolidinone compositions; oxazolidinone combinational libraries; and methods for their preparation and use. BACKGROUND ART Oxazolidinones are compounds where an amine group and a hydroxyl group on adjacent carbon atoms have been cyclized to form a 5-membered ring containing a carbonyl group. Certain oxazolidinones have been shown to exhibit a variety of biological activities. For example, some oxazolidinones are inhibitors of monoamine oxidase-B, an enzyme implicated in Parkinson's disease. See, for example, Ding et al., J. Med. Chem. 36:3606-3610 (1993). A a ten step synthesis of oxazolidinone antibiotics has been described. U.S. Pat. No. 5,547,950. A four step synthesis of the antibacterial compound U-100592 also has been reported; Schauss et al., Tetrahedron Letters, 37:7937-7940 (1996). A five step preparation of enantiomerically pure cis- and trans-N-(propionyl)hexahydrobenzoxazolidin-2-ones furthe...

AI Technical Summary

Benefits of technology

Provided are oxazolidinones and combinatorial libraries, compositions comprising oxazolidinones, as well as methods of their synthesis and use. Using the methods provided herein, one of skill in the art can rapidly produce the large number of compounds required for high-throughput screening.

Problems solved by technology

These laborious methods can provide a limited number of compounds for evaluation in a biological screen.

These methods cannot, however, provide the number of compounds required to supply a high-throughput biological screen, an assay technique whereby the activity of thousands of drug candidates, for example, per week, may be analyzed.
