3-溴-5-氟三氟甲苯在常温常压下呈现无色或浅黄色液体的状态。其苯环上的溴单元可以通过Suzuki偶联反应连接一个芳基;也可以将溴转换为硼单元,进一步通过多种硼化学转化来衍生化该化合物。
用途3-溴-5-氟三氟甲苯是一种烃类衍生物,广泛用作药物分子和有机合成的中间体。
合成方法首先,将苯胺的前体化合物与6M HCl 10 mL 放入200 mL 烧杯中,并加热5分钟(使用热风枪)。然后,在-5 °C 下,向反应混合物中滴加NaNO2 (393 mg, 5.7 mmol) 在3 mL 水中的溶液。将所得澄清溶液小心倒入含有NaI(2.43 g,16.2 mmol)溶解在20 mL 水中的溶液中,并在室温下搅拌反应混合物10小时。用CH2Cl2 萃取反应混合物,然后依次用10% NaHSO3 溶液、2M NaOH 溶液和盐水洗涤合并的有机层。最后,使用Na2SO4 干燥并浓缩合并后的有机层。
The efficacy and side-effects of drugs do not just reflect the biochemical and pharmacodynamic properties of the parent compound, but often comprise of cooperative effects between the properties of the parent and active metabolites. Metabolites of imatinib, nilotinib and midostaurin have been synthesised and evaluated in assays to compare their properties as protein kinase inhibitors with the parent drugs. The N-desmethyl-metabolite of imatinib is substantially less active than imatinib as a BCR-ABL1 kinase inhibitor, thus providing an explanation as to why patients producing high levels of this metabolite show a relatively low response rate in chronic myeloid leukaemia (CML) treatment. The hydroxymethylphenyl and N-oxide metabolites of imatinib and nilotinib are only weakly active as BCR-ABL1 inhibitors and are unlikely to play a role in the efficacy of either drug in CML. The 3-(R)-HO-metabolite of midostaurin shows appreciable accumulation following chronic drug administration and, in addition to mutant forms of FLT3, potently inhibits the PDPK1 and VEGFR2 kinases (IC50 values
