  Synthesis and biological evaluation of novel 5-(hydroxamic acid)methyl oxazolidinone derivatives

  摘要：

  Research activities on the oxazolidinone antibacterial class of compounds continue to focus on developing newer derivatives with improved potency, broad-spectrum activity and safety profiles superior to linezolid. Among the safety concerns with the oxazolidinone antibacterial agents is inhibition of monoamine oxidases (MAO) resulting from their structural similarity with toloxatone, a known MAO inhibitor. Diverse substitution patterns at the C-5 position of the oxazolidinone ring have been shown to significantly affect both antibacterial activity and MAO inhibition to varying degrees. Also, the antibacterial activity of compounds containing iron-chelating functionalities, such as the hydroxamic acids, 8-hydroxyquinolines and catechols have been correlated to their ability to alter iron intake and/or metabolism. Hence a series of novel 5-(hydroxamic acid)methyl oxazolidinone derivatives were synthesized and evaluated for their antibacterial and MAO-A and -B inhibitory activities. The compounds were devoid of significant antibacterial activity but most demonstrated moderate MAO-A and -B inhibitory activities. Computer modeling studies revealed that the lack of potent antibacterial activity was due to significant steric interaction between the hydroxamic acid N-OH oxygen atom and one of the G2540 5'-phosphate oxygen atoms at the bacterial ribosomal binding site. Therefore, the replacement of the 5-acetamidomethyl group of linezolid with the 5-(N-hydroxyacetamido)methyl group present in the hydroxamic acid oxazolidinone derivatives was concluded to be detrimental to antibacterial activity. Furthermore, the 5-(hydroxamic acid)methyl oxazolidinone derivatives were also less active as MAO-A and -B inhibitors compared with linezolid and the selective inhibitors clorgyline and pargyline. In general, the 5-(hydroxamic acid)methyl oxazolidinone derivatives demonstrated moderate but selective MAO-B inhibitory activity. (C) 2015 Elsevier Masson SAS. All rights reserved.

  The oxazolidinone class of antimicrobial agents represents a promising advance in the fight against resistant Gram-positive bacterial infections. To improve antibacterial activity and expand the spectrum of activity including Gram-negative bacteria, a series of novel 5-acetylthiomethyl oxazolidinone analogs were designed and synthesized based on the structure–activity relationship studies.
