Spectral studies of 2-pyrazoline derivatives: Structural elucidation through single crystal XRD and DFT calculations
A series of biologically active N-thiocarbamoyl pyrazoline derivatives have been synthesized using anhydrous potassium carbonate as the catalyst. All the synthesized compounds were characterized by FT-IR, H-1 NMR, C-13 NMR spectral studies, LCMS, CHN Analysis and X-ray diffraction analysis (compound 7). In order to supplement the XRD parameters, molecular modelling was carried out by Gaussian 03W. From the optimized structure, the energy, dipolemoment and HOMO-LUMO energies of all the systems were calculated. (C) 2013 Elsevier B.V. All rights reserved.

A series of new 2-pyrazoline derivatives has been synthesized by reacting 3-(substituted-phenyl)-1-pyridin-2-yl-propenones using two routes one using thiosemicarbazide and the other by hydrazine hydrate. The chemical structures were established by IR, Mass, H-1-NMR, C-13-NMR spectroscopic data, and elemental analysis. The anticonvulsant activity of the synthesized compounds was evaluated by the "maximal electroshock seizure" (MES) test and pentylenetetrazole (PTZ) test using male albino mice. Compounds 2e, 5-(naphthalene-1-yl)-3-(pyridine-2-yl)-4,5-dihydro-1H-pyrazole-1-carbothioic acid amide, and 3c, N-ethyl-5-(naphthalene-1-yl)-3-(pyridine-2-yl)-4,5-dihydro-1H-pyrazole-1-carbothioamide showed appreciable activity in the MES as well as PTZ test at all the evaluated doses.
EGFR/HER-2 inhibitors: synthesis, biological evaluation and 3D-QSAR analysis of dihydropyridine-containing thiazolinone derivatives
A series of dihydropyridin containing thiazolinone derivatives (4a–4r) have been designed, synthesized and their biological activities were also evaluated as potential EGFR and HER-2 kinase inhibitors and tumor cell antiproliferation.
