Synthesis and structure–activity relationships of N-benzyl-N-(X-2-hydroxybenzyl)-N′-phenylureas and thioureas as antitumor agents
摘要:
Two series of novel N-benzyl-N-(X-2-hydroxybenzyl)-N'-phenylureas and thioureas (1a-18a; 1b-18b) as potential EGFR and HER-2 kinase inhibitors have been discovered. These compounds displayed good EGFR and HER-2 inhibitory activity and the SARs are also been studied. Especially compound 7b demonstrated significant EGFR and HER-2 inhibitory activity (IC50 = 0.08 mu M for EGFR and IC50 = 0.35 mu M for HER-2). Docking simulation was performed to position compound 7b into the EGFR active site to determine the probable binding conformation and antiproliferative assay results indicating that these series of urea and thioureas own high antiproliferative activity against MCF-7. Above all, thiourea 7b would be a potential anticancer agent deserves further research. (C) 2009 Elsevier Ltd. All rights reserved.

Cross-linked terpolymers made up of phenol, diaminoalkane and formaldehyde monomeric units. The cross-linked terpolymers are synthesized via a Mannich mechanism in n-heptane, characterized with multiple spectroscopic techniques, scanning electron microscopy and powder X-ray diffraction, and are also investigated for their Pb2+ adsorption capacity and thermodynamic properties. A method of removing Pb2+ ions from an aqueous solution or a wastewater sample with these cross-linked terpolymers is also described.
