The synthesis and antibacterial activity of 1,3,4-thiadiazole phenyl oxazolidinone analogues.

ABSTRACT

Replacement of the morpholine C-ring of linezolid 1 with a 1,3,4-thiadiazolyl ring leads to oxazolidinone analogues 5 having potent antibacterial activity against both gram-positive and gram-negative organisms. Conversion of the C5 acetamide group to a thioacetamide further increases the potency of these compounds.
