  Design, synthesis, and biological evaluation of novel quinazolinyl-diaryl urea derivatives as potential anticancer agents

  摘要：

  Through a structure-based molecular hybridization approach, a series of novel quinazolinyl-diaryl urea derivatives were designed, synthesized, and screened for their in vitro antiproliferative activities against three cancer cell lines (HepG2, MGC-803, and A549). Six compounds (7g, 7m, 7o, 8e, 8g, and 8m) showed stronger activity against a certain cell line compared with the positive reference drugs sorafenib and gefitinib. Among the six compounds, 8g exhibited the strongest activity. In particular, compound 8g induced A549 apoptosis, arrested cell cycle at the G0/G1 phase, elevated intracellular reactive oxygen species level, and decreased mitochondrial membrane potential. This compound can also effectively regulate the expression of apoptosis- and cell cycle-related proteins, and influence the Raf/MEK/ERK pathway. Molecular docking and structure activity relationship analyses revealed that it can bind well to the active site of the receptor c-Raf, which was consistent with the biological data. Therefore, compound 8g may be a potent antitumor agent, representing a promising lead for further optimization. (C) 2015 Elsevier Masson SAS. All rights reserved.

  Synthesis and in vitro anti-bladder cancer activity evaluation of quinazolinyl-arylurea derivatives

  摘要：

  Based on the structural modification of molecular-targeted agent sorafenib, a series of quinazolinylarylurea derivatives were synthesized and evaluated for their anti-proliferative activities against six human cancer cell lines. Compared with other cell lines tested, T24 was more sensitive to most compounds. Compound 7j exhibited the best profile with lower IC50 value and favorable selectivity. In this study, we focused on 7j-induced death forms of T24 cells and tried to elucidate the reason for its potent proliferative inhibitory activity. Compound 7j treatment could trigger three different cell death forms including apoptosis, ferroptosis, and autophagy; which form would occur depended on the concentrations and incubation time of 7j: (1) Lower concentrations within the initial 8 h of 7j treatment led to apoptosis-dependent death. (2) Ferroptosis and autophagy occurred in the case of higher concentrations combining with extended incubation time through effectively regulating the Sxc(-)/GPx4/ROS and PI3K/ Akt/mTOR/ULK1 pathways, respectively. (3) The above death forms were closely associated with intracellular ROS generation and decreased mitochondrial membrane potential induced by 7j. In molecular docking and structure-activity relationship analyses, 7j could bind well to the active site of the corresponding receptor glutathione peroxidase 4 (GPx4). Compound 7j could be a promising lead for molecular-targeted anti-bladder cancer agents' discovery. (C) 2020 Elsevier Masson SAS. All rights reserved.

  moiety were designed and synthesized, and their structures were fully characterized by 1H NMR, 13C NMR, and HRMS techniques. Among them, the structures of compounds 5A10 and 5B11 were further confirmed through X-ray single-crystal diffraction analyses. The bioassay results indicated that some of the target compounds displayed higher inhibition activities in vitro against the tested phytopathogenic bacteria
