The designed compounds were primarily screened for their ability to inhibit pancreatic α-amylase enzyme using in silico molecular docking approach. The compounds with good binding energies (−8.0 to −6.9 kcal/mol) when compared with standard drug, acarbose (−8.0 kcal/mol) were prompted for the synthesis. The structures of the newly prepared compounds were confirmed by their spectroscopic analyses. They were further screened in vitro for their inhibition toward α-amylase enzyme using acarbose as standard drug. All compounds exhibited moderate to good inhibition potential with IC50 values in the range of 54.14 ± 0.35 to 185.04 ± 0.53 µg/mL when compared with the standard drug (IC50, 50.47 ± 0.28 µg/mL).

These complexes crystallize in three crystal systems: monoclinic (8 examples), triclinic (4 examples) and orthorhombic (4 examples). Distorted square-planar environments about the Pt(II) atoms are built up by combination of homobi-P,P with two monodentate Si donor ligands; homobi-PP with homo-Si,Si donor ligands, or heterobi-P,Si donor ligands. The chelating ligands create metallacycles with the following angles: 65.0° (SiOSi) < 83.1° (SiC2Si) < 85.2° (PC2P) < 88.8° (SiSi2Si)). The mean Pt-P and Pt-Si bond distances in Pt(η2-P2L)·(SiL)2 complexes are 2.319 and 2.365 Å; in Pt(η2-P2L)(η2-Si2L) the values are 2.316 and 2.360 Å. The complex [Pt{η2-Me2P(C2B10H10)SiMe2}2] exists in two isomeric forms, a monoclinic cis- and a triclinic trans-isomer. The structural data are compared and discussed with the complexes of inner coordination spheres: Pt(η2-P2L)(XL)2 (X = O, N, CN, BL, Cl, SL, SeL, Br, or I) and Pt(η2-P2L)(η2-X2L) (X = OL, NL, SL or SeL).

The HSCNs were prepared by using SiO2 as a hard template. The chemical structure, porosity, morphology and electronic property of the prepared catalysts were investigated using XRD, SEM, N2-absorption isotherm and XPS. The results indicated that the modified HSCN show prominent absorption in the visible light range and decrease the band gap. The greatly enhanced photocatalytic activity of obtained CuCN-X have been shown by the degradation of Rhodamine B (RhB), reduction of CO2 and production of photocatalytic hydrogen under visible light irradiation. More significantly, CuCN-15 has shown significantly improved photocatalytic performance at 4.5, 3.5 and 3.3 times higher that of than HSCN for the degradation of RhB, reduction of CO2 and production of photocatalytic hydrogen, respectively. Furthermore, the mechanism for the enhanced photocatalytic activity of CuCN-X is proposed to be due to the formation of heterojunction. The electrons can be rapidly transferred from HSCN to HPW11Cu, in which facilitate charge separation and charge transfer.
