Anti-tubercular agents. Part 6: synthesis and antimycobacterial activity of novel arylsulfonamido conjugated oxazolidinones.


PMID 21272965

Abstract

As a part of investigation of new anti-tubercular agents in this laboratory, herein we describe the synthesis of a new class of arylsulfonamido conjugated oxazolidinones. The in vitro activity of these conjugated (6a-f, 7a-d, 9a-c and 11a-c) molecules against Mycobacterium tuberculosis H(37)Rv by using rifampicin and linezolide as positive controls is discussed, compounds 7c and 9a-c are found to be the most active members in this series. Further, cytotoxicity of the potent conjugates of the series (7c, and 9a-c) was evaluated on human foreskin fibroblast (HFF) cells by using MTT assay. Finally, these studies suggest that compounds 7c and 9a may serve as promising lead scaffolds for further generation of new as anti-TB agents.
