The p53 stabilizing agent CP-31398 and multi-kinase inhibitors. Designing, synthesizing and screening of styrylquinazoline series
摘要:
Quinazoline derivatives constitute a large family of small-molecule inhibitors of tyrosine kinases. In the current study, the p53 protein reactivator CP-31398 was tested against a panel of kinases on the assumption that it was structurally similar to other active inhibitors. Although it was found to be active in the enzyme-based assay, this compound did not block the proliferation of cancer cells at a feasible concentration level. The styrylquinazoline was used to design new structures that might be potential multitarget inhibitors. Subsequently, a series of compounds was obtained and characterized. Their inhibitory activity in a panel of tyrosine kinases had an antiproliferative effect against several cancer cell lines that have different expression levels of those proteins. The mode of protein interaction was tested for the most active compound in docking experiments. (C) 2018 Elsevier Masson SAS. All rights reserved.
In this study, series of ring-substituted 2-styrylquinazolin-4(3H)-one and 4-chloro-2-styrylquinazoline derivatives were prepared. The syntheses of the discussed compounds are presented. The compounds were analyzed by RP-HPLC to determine lipophilicity. They were tested for their inhibitory activity on photosynthetic electron transport (PET) in spinach (Spinacia oleracea L.) chloroplasts. Primary in vitro screening of the synthesized compounds was also performed against four mycobacterial strains and against eight fungal strains. Several compounds showed biological activity comparable with or higher than that of the standard isoniazid. It was found that the electronic properties of the R substituent, and not the total lipophilicity of the compound, were decisive for the photosynthesis-inhibiting activity of tested compounds.

A group of styrylazanaphthalenes and azanaphthalenediones were synthesized and tested for their anti-proliferative activity. Most of the compounds were obtained with the use of microwave-assisted synthesis. The lipophilicity of the compounds was measured by RP-HPLC and their anti-proliferative activity was assayed against the human SK-N-MC neuroepithelioma and HCT116 human colon carcinoma cell lines. Active compounds were also tested in clonogenity and comet assays. Several quinazolinone and styrylquinazoline analogues were found to have markedly greater anti-proliferative activity than desferoxamine and cis-platin. (C) 2010 Elsevier Ltd. All rights reserved.
