hexagonal CdS nanocrystals. The TEM studies evidenced that the chlorido precursors produced CdS nanostructures whose morphologies differed from those obtained from the iodido precursors. CdSnanoparticles in the form of cubes/spheres/rods and nanodendrite structures were obtained from CdCl2 and CdI2 thiosemicarbazonecomplexes, respectively. The UV/Vis spectra revealed that the as-synthesized CdS nanoparticles

thiosemicarbazone derivatives. The structure and mechanistic pathways for all products were discussed and proved based on spectral results, in addition to conformational studies. Our aim after the synthesis is to investigate their antimicrobial activity against various types of bacteria and fungi species. Preceeding such an investigation, a molecular docking study was carried out with selected conformers

to afford wide range of bioactive heterocyclic systems as thiazoles and imidazopyrazoles. This research work focused on the synthesis of two new fluorinated hydrazonoyl chlorides and used them in synthesis of novel series of thiazole derivatives and two imidazopyrazole systems. The mechanistic pathways and the structures of all synthesized derivatives were discussed and assured based on the available
Thirty novel pyridine-appended 2-hydrazinylthiazole derivatives have been synthesized and tested for their antimycobacterial activity against Mictrobactrium tuberculosis, H37Rv strain.
