http://www.ichemistry.cn/cas/3-Phenylpropene.htm WebSubsequently, our exploratory study toward the synthesis of pyrazolo[1,5-a]pyrimidine core began with the model reaction between the phenylpropenone (2a) and 5-amino-3-methyl-1H-pyrazole (3a) . We carried out the optimization by varying the temperature, the solvent and testing the effect of conventional heating versus microwave irradiation.
WebThe reaction mixture was refluxed for 24 hours. It was then allowed to cool at room temperature. Subsequently, it was stored in the refrigerator overnight. Filtration of the precipitate, which was formed, afforded (1.38 g, 90 %) of the desired 1-(o-hydroxyphenyl)-3-phenylpropenone -benzoylhydrazone as white crystals.
WebSU4312, initially designed as a multi-target tyrosine kinase inhibitor, is consequently reported to inhibit tumor angiogenesis by blocking VEGFR. However, although SU4312 can penetrate the brain–blood barrier, its potential to inhibit glioma growth is unknown. In this study, we report that SU4312 inhibited glioma cell proliferation and down-regulated yes-associated … Web挥发性有机物voc列表.docx 《挥发性有机物voc列表.docx》由会员分享，可在线阅读，更多相关《挥发性有机物voc列表.docx（14页珍藏版）》请在冰豆网上搜索。
