A simple and efficient catalytic synthesis of new 1H-pyrazole-1-carbothioamide derivatives through a one-pot reaction of hydrazine hydrate, arylidene malononitrile and isothiocyanates in the presence of HAp/ZnCl2 nano-flakes at 60-70°C has been described. The protocol's main advantages include high yields of products, a wide range of substrates, simple procedure, and short reaction time. Molecular docking studies of the designed compounds were accomplished as COX-2 inhibitors and showed that compounds 3d, 3e, 3h, and 3n give promising results compared with celecoxib as a reference drug.

AbstractTwo pyrazol-4-carboxamides, 3-(difluoromethyl)-N-(mesitylcarbamoyl)-1-methyl-1H-pyrazole-4-carboxa-mide (7a) and 3-(difluoromethyl)-N-((3,5-dimethylphenyl) carbamoyl)-1-methyl-1H-pyrazole-4-carboxamide (7b) were synthesized and their structures were confirmed by the aid of 1H NMR and HRMS analyses. The structure of the pyrazole-4-carboxamide, 7a was also determined by X-ray diffraction. The preliminary activity results demonstrate that these two compounds exhibit good inhibitory activity against Botrytis cinerea. Further docking results indicated that the key active group is difluoromethyl pyrazole moiety.

Present study was an attempt to investigate the bioactive components present in the leaves of Guaiacum officinale using gas chromatography-mass spectroscopy (GC-MS) analysis and study the antiinflammatory potential of those constituents using molecular docking studies. GC-MS analysis was done by standard protocol using the equipment JEOL GC MATE II. The identification of components was based on NIST (National Institute of Standards and Technology) Version-11 library as well as comparison of their retention indices. The molecular docking studies were done using the commercial docking software MCULE, 1-click docking. GC-MS analysis of the alcoholic extract showed the presence of ten compounds at different retention times. The phytoconstituent 8,11,14-eicosatrienoic acid was present at high concentration with % peak area of 43.3 at a retention time of 19.43 min followed by 5,7-dihydroxy-8-methoxy flavone (Wogonin) at a retention time of 17.73. All 10 compounds obtained from GC-MS analysis and diclofenac were used as the ligands in this study, with cyclooxygenase-2 (COX-2), phospholipase A2 and interleukin receptor as the molecular targets. in silico Docking studies revealed that the flavanoid Wogonin is having highest binding potential indicated by least docking score of -8.2, -8 and -6.9 kcal/mol on COX-2, phospholipase A2 and interleukin receptor respectively.
