Four oxazolidinone analogues(6, 7, 8, 9), which are isosters of 5, were synthesized by the reaction of 2-chloroalkyl-3,5-dimethyl-4-methoxypyridine with the corresponding benzox azolidinone or oxazolidinone, respectively, and were evaluated for their inhibitory activities toward proton pump enzyme under in vitro condition. Isosteric substitution of the benzothiazolidine moiety in 5 with benzoxazolidinone rendered the molecule relatively inactive.

Several oxazolidinones, a new class of synthetic antibacterial agents, have shown biological activity against multidrug-resistant gram positive organisms such as staphylococci, streptococci, and enterococci. Previous results of our studies with benzoxazolidinone phosphonate derivatives have demonstrated very low antibacterial activity. In the course of our studies directed towards the discovery of noble antibacterial agents, we have synthesized several new derivatives of oxazolidinone phosphonates prepared efficiently from commercially available amino acids. These compounds are tested for in vitro antibacterial activity and one of the compounds showed promising results allowing us to pursue further studies.
