Heterocyclyl Tetracyclines. 1. 7-Trifluoromethyl-8-Pyrrolidinyltetracyclines: Potent, Broad Spectrum Antibacterial Agents with Enhanced Activity against Pseudomonas aeruginosa
Utilizing a total synthesis approach, the first 8-heterocyclyltetracyclines were designed, synthesized, and evaluated against panels of tetracycline- and multidrug-resistant Gram-positive and Gram-negative pathogens. Several compounds with balanced, highly potent in vitro activity against a broad range of bacterial isolates were identified through structure-activity relationships (SAR) studies. One compound demonstrated the best antibacterial activity against Pseudomonas aeruginosa both in vitro and in vivo for tetracyclines reported to date.
The present invention is directed to a compound represented by Structural Formula (I), or a pharmaceutically acceptable salt thereof. The variables for Structural Formula (I) are defined herein. Also described is a pharmaceutical composition comprising the compound of Structural Formula (I) and its therapeutic use.
