In the present study, the synthesis of diethylene triamine supported on cellulose biopolymer as a biodegradable solid basic heterogeneous catalyst was suggested. Then, the applicability of the synthesized catalyst cellulose bonded N-propyl diethylene triamine (CBPDETA) was tested for the synthesis of oxindole derivatives, an important class of potentially bioactive compounds. A various series o...

<p>In silico study by molecular docking, drug discovery, and virtual screening are useful for obtaining compounds with promising biological activity. The force fields energy minimization in docking is the overall process to produce better geometry estimation ligand-receptor affinity. In this study, divide conquer algorithm based on Mikowski matrix MarvinSketch conjugate gradient of Open B...

A novel magnetically immobilized polyethyleneimine (PEI) fabricated by covalently anchoring on silica coated Fe3O4 nanoparticles (PEI@Si-MNPs) was prepared. The synthesized catalyst was characterized by Fourier transform infrared (FT-IR), thermogravimetric analysis (TGA), X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and vibrating sample magnetometry (VSM). The immobili...
