Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. Reference of 70918-54-6
Two series of novel 2,3-dihydrobenzo[b][1,4]dioxin-containing 4,5-dihydro-1H-pyrazole derivatives C1-C15 and D1-D15 have been synthesized and evaluated for their B-Raf inhibitory and anti-proliferation activities. Compound C14 ((3-(4-bromophenyl)-5-(2-fluorophenyl)-4,5-dihydro-1H-pyrazol-1-yl)(2,3- dihydrobenzo[b][1,4]dioxin-6-yl)methanone) showed the most potent biological activity against B-RafV600E (IC50 = 0.11 muM) and WM266.4 human melanoma cell line (GI50 = 0.58 muM), being comparable with the positive control Erlotinib and more potent than our previous best compound, while D10 ((2,3-dihydrobenzo[b][1,4]dioxin-2-yl)(5-(3- fluorophenyl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl)methanone) performed the best in the D series (IC50 = 1.70 muM; GI50 = 1.45 muM). The docking simulation was performed to analyze the probable binding models and poses and the QSAR model was built for reasonable design of B-Raf inhibitors in future. The introduction of 2,3-dihydrobenzo[b][1,4]dioxin structure reinforced the combination of our compounds and the receptor, resulting in progress of bioactivity.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.
