structural properties of coordination polymers (COPs), together with the huge variety of metal ions and organic linkers to choose from, make COPs potential precursors for fabricating carbon-encapsulated metal and metal oxide nanoparticles (NPs). Herein, we have studied the role of the COP structural assembly, prepared through making subtle changes to the ligand structure, on the formation of NPs in

unclear. A medium throughput screen led to the identification of N-(2(-9H-carbazol-1-yl)phenyl)acetamide (GeA-69, 1) as a novel allosteric PARP14 MD2 (second MD of PARP14) inhibitor. We herein report medicinal chemistry around this novel chemotype to afford a sub-micromolar PARP14 MD2 inhibitor. This chemical series provides a novel starting point for further development of PARP14 chemical probes.

DFT calculations provided a predictive model, which states that substrates containing a C(sp3)–H bond with a sufficiently low pKa value should readily undergo arylation. The DFT prediction was confirmed through experimental testing of nearly a dozen substrates containing activated C(sp3)–H bonds. This arylation method was also used in a one-pot protocol to synthesize over twenty compounds containing
已开发出一种无过渡金属的脱氢方法,用于直接活化多种活化的C(sp 3)-H键。这种操作简单且对环境友好的好氧芳构化反应使用叔-BuOK为基础,硝基芳烃为亲电子试剂,可制备多达克数量的结构多样的α-芳基化酯,酰胺,腈,砜和三芳基甲烷(超过60个实例)。DFT计算提供了一个预测模型,该模型指出,含有C(sp 3)-H键且p K a值足够低的底物应易于芳构化。通过对包含活化C(sp 3)– H键。这种芳基化方法还用于一锅法操作,以合成超过20种包含全碳四元中心的化合物。
