The new analogues of ribofuranose fused heterocyclic compounds were synthesized a series of diazotization, cyclization, coupling and hydrolysis reactions and structures were characterized by spectroscopic methods. To explain the spectroscopic properties in detail, such as molecular geometric parameters, vibrational wavenumbers, HOMO-LUMO energies, 1H NMR chemical shift values and electronic transitions, density functional theory (DFT) calculations were used. The structural and spectroscopic data of the molecules in the ground state were calculated by DFT using B3LYP functional with 6-311G(d,p) basis set. Isotropic chemical shifts were calculated using the gauge-invariant atomic orbital (GIAO) method. Furthermore molecular docking (ligand–protein) simulations were performed to obtain antiproliferative activity of the synthesized ribofuranose nucleoside analogues against epidermal growth factor receptor and vascular endothelial growth factor receptor 2. Full fitness score and binding energy length values revealed that studied three compounds can act as potential inhibitor against selected receptors.

Ethyl-2-[diazo(substituted benzene) acetoacetates (2a-h) were treated with benzhydrazide (3) to yield the title compounds pyrazolone derivatives (4a-h). All the new compounds were characterized by IR, 1H-NMR, Mass and elemental analysis. The title compounds were subjected to in-vitro antidiabetic activity by α-amylase and α-glucosidase inhibitory activity. Compounds 4b and 4c showed good antidiabetic activity when compared to the standard drug acarbose.

Inhibitors of alpha-Amylase are targets for the development of novel drugs for the treatment of diabetes and obesity. Alpha amylase is an enzyme which increases the bio availability of glucose in the blood. Hence, the inhibition effects of alpha amylase of 2-[1-(4-isobutylphenyl)ethyl]-5-methyl-4-[2-(aryl- substituted)hydrazinylidene]-2,4-dihydro-3H-pyrazol-3-one (4a-l) were investigated, among them compounds 4d, 4f, 4a, and 4g have displayed good inhibitory activity. The compounds with significant results were further evaluated for their molecular modeling study using in silico method. The new series of compounds were synthesized by solvent-free microwave irradiation method and were characterized by spectral and analytical data.
