New discoveries in chemical research and development in 2021. The transformation of simple hydrocarbons into more complex and valuable products has revolutionised modern synthetic chemistry. In an article, author is Labib, Madlen B., once mentioned the application of 540-36-3, Product Details of 540-36-3, Name is 1,4-Difluorobenzene, molecular formula is C6H4F2, molecular weight is 114.0928, category is benzoxazole. Now introduce a scientific discovery about this category.
In this research, three series of azole-hydrazone derivatives namely, benzimidazole, benzoxazole and benzothiazole were designed and synthesized. Their structures were confirmed by elemental analysis and spectroscopic techniques. Stereochemical configuration of the synthesized compounds (Z/E) was determined. The new derivatives were tested in vitro against both human breast adenocarcinoma (MCF-7) and human hepatic adenocarcinoma (HepG2) cell lines. The most active compounds 3h (IC50 = 0.067 mu M against MCF-7) and 3l (IC50 = 0.027 mu M against HepG2) were further tested for Epidermal Growth Factor Receptor (EGFR) inhibitory activity. The most active 3h on EGFR was then screened for HER2 and VEGFR enzymes. Caspase-3/9 protein level expression were measured for the two compounds 3h and 3l. Cell cycle analysis showed pre G1 apoptosis and cell cycle arrest at G2/M phase. Up-regulation of Bax and down-regulation of Bcl-2 protein expression level confirmed apoptosis. Molecular docking analysis was performed for all the synthesized compounds inside the active site of EGFR. (C) 2017 Elsevier Inc. All rights reserved.
