AlCl@ZnO nanostructured material: an efficient green catalyst for the one-pot solvent-free synthesis of 1,4-dihydropyridines.

AlCl-loaded ZnO nanoparticles have been explored as an efficient catalyst for 1,4-dihydropyridine synthesis under ambient temperature and solvent-free conditions. For this purpose, ZnO nanoparticles were synthesized by a simple solution-based precipitation technique using a stoichiometric amount of zinc sulfate and oxalic acid. The AlCl@ZnO nanocrystalline catalyst was prepared by loading 20% AlCl on ZnO nanoparticles by a simple wet-impregnation technique.

ZnCl loaded TiO nanomaterial: an efficient green catalyst to one-pot solvent-free synthesis of propargylamines.

One-pot green synthesis of propargylamines using ZnCl loaded TiO nanomaterial under solvent-free conditions has been effectively accomplished. The aromatic aldehydes, amines, and phenylacetylene were reacted at 100 °C in the presence of the resultant catalyst to form propargylamines. The nanocrystalline TiO was initially synthesized by a sol-gel method from titanium(iv) isopropoxide (TTIP) and further subjected to ZnCl loading by a wet impregnation method.

Nanocrystalline Cu-ZnO as an Green Catalyst for One Pot Synthesis of 4,4'-((phenyl)methylene)bis(3-methyl-1-phenyl-1H-pyrazol-5-ol) Derivatives.

Synthesis of 4,4'-((phenyl)methylene)bis(3-methyl-1-phenyl-1H-pyrazol-5-ol) derivatives was successively carried out using Cu doped ZnO nanomaterials. The nanocrystalline Cu-ZnO was obtained by decomposing as-synthesized copper-zinc oxalate intermediate at 520 °C. The prepared Cu-ZnO nanostructured catalyst was characterized with FTIR, X-ray diffraction, field emission scanning electron microscope and electron diffraction techniques.

Design, synthesis and biological evaluation of novel inosine 5'-monophosphate dehydrogenase (IMPDH) inhibitors.

This study is based on our attempts to further explore the structure-activity relationship (SAR) of VX-148 (3) in an attempt to identify inosine 5'-mono-phosphate dehydrogenase (IMPDH) inhibitors superior to mycophenolic acid. A five-point pharmacophore developed using structurally diverse, known IMPDH inhibitors guided further design of novel analogs of 3. Several conventional as well as novel medicinal chemistry strategies were tried.
