Oxazolidinones represent a new and promising class of antibacterial agents. Current, research in this area is mainly concentrated on improving the safety profile and the antibacterial spectrum. Many oxazolidinones, including linezolid (marketed as 2 Zyvox), are inhibitors of monoamine oxidase A (MAO-A), which presents an undesired side effect. Recently, it was found that the 1,2,3-triazole is a good replacement for the conventional acetamide functionality found in oxazolidinones. We now disclose the finding that 1,2.3-triazoles bearing, a substituent like methyl, small substituted methyl, bromo, or a linear (sp-hybridized) group at the 4 position (compounds such as 5, 16, 19, and 21) are good antibacterials with reduced or no activity.. within the detection limit of the assay, against MAO-A. The results are especially promising for the development of oxazolidinones with an improved safety profile. The MAO-A SAR can be rationalized on the basis of docking studies to a MAO-A/MAO-B homolog; model.
