SYNTHESIS AND BILOGICAL SIGNIFICANCE OF

ABSRTACT

Due to the challenge posed by microbial resistance to broad spectrum of antibiotics, there has been a great need to synthesize of a novel compound which has a different mechanism of action on microbial activity. 1,2,4-oxadiaxolidin-5-One constitute an important class of compound with tremendous potential as pharmaceutical and otherwise biologically relevance substance due to the fact that its five member ring is a configurationally stable building block. This unit is found in other compound like alkaloids, with vast medical application. This study describes the synthesis of 1,2,4-oxadiaxolidin-5-one in two-step procedure using nitroethane and benzaldehyde as starting materials to produce nitrone, which in turn undergoes 1,3- dipolar cycloaddition with phenyl isocyanate to give 1,2,4-oxadiaxolidin-5-one. The product was characterized using proton NMR and GC-MS. There is an ongoing investigation on the summary of some important inhibitory activity against class A β-lactamase by 1,2,4-oxadiaxolidin-5-one heterocyclic core structure to provide effective antimicrobial β-lactamase inhibitors, hence, solving the problem of microbial resistance to currently used antimicrobial drugs.
