A new series of hydrazino thiazolyl-2-azetidinone 4(a-i) derivatives were synthesized efficiently using benzylidene hydrazinyl thiazole derivatives 3(a-i). The precursors, benzylidene hydrazinyl thiazoles were prepared by reacting 4- fluoro phenacyl bromide with thiosemicarbazones 2(a-i). All the structures of the synthesized compounds were ascertained by IR, NMR and mass spectral analysis

ORTEP drawings of compounds 8g, 8h and 9f provide strong evidence of the structure of aromatic thiazole derivatives 8a-h and 9a-h. Undoubtedly, the structure of compounds 3e-h and 4e-h synthesized by the reaction of 3-aryl-4-formylsydnone thiosemicarbazones 1e-h with cyclization reagents 2a and 2b in the previous work should have the thiazole moiety, and not the thiazoline moiety. Both the new thiazole

adenosine A3 receptors. Molecular modeling study of conformation search and receptor docking experiments to investigate the dramatic differences of binding affinities between two regioisomers of thiadiazole analogues, (39) and (42), suggested possible binding mechanisms in the binding pockets of adenosine receptors.

density functional theory (TD-DFT) was performed to simulate the electronic spectra of the complex 1 with the help of Polarizable Continuum Model (PCM) model. Complex 1 acts as functional models. The catalytic property has been evaluated from Lineweaver-Burk plot using the Michaelis-Menten approach of enzyme catalysis with a kcat value of the order of 708 h-1.
