is the ubiquitous and hypoxia‐induced isoform of PFK‐2, are reported. X‐ray crystallography and docking were instrumental in the design and optimisation of a series of N‐aryl6‐aminoquinoxalines. The most potent representative, N‐(4‐methanesulfonylpyridin‐3‐yl)‐8‐(3‐methyl‐1‐benzothiophen‐5‐yl)quinoxalin‐6‐amine, displayed an IC50 of 14 nm for the target and an IC50 of 0.49 μm for fructose‐2,6‐biphosphate
癌细胞的能量和生物质生产在很大程度上被有氧糖酵解所支持,这就是所谓的Warburg效应。该过程受关键酶的调节,其中磷酸果糖激酶PFK-2通过产生果糖-2,6-二磷酸而起重要作用。磷酸果糖激酶PFK-1执行的最有效的糖酵解限速步骤激活剂。本文介绍了6-磷酸果糖-2-激酶/果糖-2,6-二磷酸酯酶3(PFKFB3)的新型抑制剂的合成,生物学评估以及其结构与活性之间的关系,PFKFB3是一种普遍存在且由低氧引起的PFK-2亚型,被报道。X射线晶体学和对接有助于设计和优化一系列N-芳基6-氨基喹喔啉。最有力的代表,N-(4-甲磺酰基吡啶-3-基)-8-(3-甲基-1-苯并噻吩-5-基)喹喔啉-6-胺,目标物的IC 50为14 n m,0.4的IC 50为0.49μm m为人类结肠癌HCT116细胞中果糖2,6-二磷酸的产生。这项工作为PFKFB3抑制剂领域的发展提供了新的机会。

A practical and mild set of conditions for the Sonogashirareaction utilizing CsF-mediated in situ TMS-alkyne desilylation followed by Sonogashira coupling has been developed for the synthesis of a variety of alkynyl benzenes and heteroarenes in good to excellent yields. This methodology demonstrates excellent functional group tolerance and simple purification, which allows large-scale industrial applications
