Trovafloxacin, a novel broad spectrum antibacterial, contains the unusual (1alpha,5alpha,6alpha)-3-azabicyclo[3.1.0]hexane ring system. The prototype of the industrial synthesis of this ring system and possible mechanistic pathways to exclusive formation of the exo or 6alpha-nitro derivative 4 are described, which leads to the key 6a-nitro-3-azabicyclo[3.1.0]hexane intermediate 10. The synthesis of 6a-amino-3-azabicyclo[3.1.0]hexane 16 and useful protected cxo 6-amino derivatives 15 and 17 follows from 10. These can be coupled with the 7-chloronaphthyridone 18 to yield protected trovafloxacin compounds 20-22 in good yield. The ethyl ester of trovafloxacin 21 can also be accessed from the product of coupling 19, derived from 18 and the exo 6-nitro-3-azabicyclo[3.1.0]hexane compound 12. Removal of protecting groups from 20-22 with methanesulfonic acid yields trovafloxacin mesylate from which trovafloxacin zwitterion 1 can be liberated with base treatment. Zwitterion l can also be prepared directly from 16 tosylate salt and naphthyridone-2-carboxylic acid 26. The Royal Society of Chemistry 2000.

4-Oxo-1,8-naphthyridine- and 4-oxoquinoline-3-carboxylic acids (2a, b and 3a-l) possessing a 1-aminocyclopropyl group at the 7-position have been synthesized and evaluated for in vitro antibacterial activities. The three quinolones (3d, h, i) exhibited potent antibacterial activities against both gram-positive and gram-negative bacteria, which are comparable to those of ciprofloxacin (CPFX) and ofloxacin (OFLX). Among the three compounds, the best pharmacological and pharmacokinetic profile was obtained with 3i, an OFLX analogue, which was considerably less toxic than three reference quinolones (1, CPFX, and OFLX).

Rifamycin derivatives having antimicrobial activities, including activities against drug-resistant microorganisms are claimed in this invention. The inventive rifamycin derivatives are uniquely designed in that they have a rifamycin moiety covalently linked to a linker group through the C-3 carbon of the rifamycin moiety and the linker is, in turn covalently linked to a therapeutic moiety or antibacterial agent/pharmacophore. The therapeutic moiety can be a quinolone, an oxazolidinone, a macrolide, an aminoglycoside, a tetracycline core or a structure/pharmacophore associated with an antibacterial agent.

The bactericidal activities of monotherapy with trovafloxacin (-0.37 ¡À 0.15 Deltalog10 CFU/ml ¡¤ h), vancomycin (-0.32 ¡À 0.12 Deltalog10 CFU/ml ¡¤ h), and ceftriaxone (-0.36 ¡À 0.19 Deltalog10 CFU/ml ¡¤ h) for the treatment of experimental meningitis in rabbits due to a clinical penicillin-resistant pneumococcal strain (MIC, 4 mg/liter) were similar. The combination of ceftriaxone with trovafloxacin considerably improved the killing rates (-0.67 ¡À 0.16 Deltalog10 CFU/ml ¡¤ h) and was slightly superior to ceftriaxone with vancomycin (killing rate, -0.53 ¡À 0.22 Deltalog10 CFU/ml ¡¤ h), the regimen most commonly used in clinical practice. In vitro, synergy was demonstrated between ceftriaxone and trovafloxacin by the checkerboard method (fractional inhibitory concentration index, 0.5) and by time-killing assays over 8 h.
