Synthesis and in vitro/in vivo antibacterial activity of oxazolidinones having thiocarbamate at C-5 on the A-ring and an amide- or urea-substituted [1,2,5]triazepane or [1,2,5]oxadiazepane as the C-ring
摘要:
Oxazolidinones bearing a seven-membered [1,2,51triazepane or [1,2,51oxadiazepane heterocycle substituted with an amide or urea functionality as the C-ring and having a [1,2,3]triazole, a thiocarbamate, an isoxazole-3-ylamino, or a thioacetamide C-5 side chain unit on the A-ring instead of the typical acetamide were synthesized and their in vitro antibacterial activities towards various pathogens were evaluated. Several derivatives exhibited potent in vitro antibacterial activity toward not only Grampositive, but also Gram-negative and linezolid-resistant pathogens. The in vivo therapeutic effects of amide 11a and ureas 16e, 17a were 2- to 3-fold greater than that of linezolid in a systemic mouse infection model treated by intravenous administration. Furthermore, compounds 11a and 17a showed lower monoamine oxidase (MAO)-inhibitory activity than our previously reported potent oxazolidinone antibacterials 3a and 3b. (C) 2013 Elsevier Masson SAS.
