  activities. In the present study, we report the synthesis and biological activities (Pim kinase inhibition and in vitro antiproliferative potency) of new 4-substituted pyrrolo[2,3-a]carbazoles. The results demonstrated that the Pim kinase inhibitory potency (especially Pim-3) can be conserved for pyrrolo[2,3-a]carbazoles bearing a methoxycarbonyl group at the 4-position without a formyl at the 3-position. Moreover

  to prepare aryl and heteroaryl iodides by sequential C–H borylation and iodination is reported. The regioselectivity of this process is controlled by steric effects on the C–H borylation step and is complementary to existing methods to form aryl iodides. The iodination of boronic esters has potential for the synthesis of radiolabeled aryl iodides, as demonstrated by the concise synthesis of a potential

  is viewed as a therapeutic target for the treatment of the disease. Accordingly, the search for small-molecule inhibitors of CDK8 is being intensified. Capitalising on our initial discovery of AU1-100, a potent CDK8 inhibitor yet with a limited degree of kinase selectivity, a structure-based optimisation was carried out, with a series of new multi-substituted pyridines rationally designed, chemically

  CDK8 在多种类型的人类癌症中失调，被视为治疗该疾病的治疗靶点。因此，正在加紧寻找 CDK8 的小分子抑制剂。利用我们最初发现的 AU1-100，一种有效的 CDK8 抑制剂，但激酶选择性有限，我们进行了基于结构的优化，对一系列新的多取代吡啶进行了合理设计、化学制备和生物学评估。这种努力最终确定了42，这是一种更有效的 CDK8 抑制剂，具有优异的运动学选择性和口服生物利用度。42抗增殖作用的机制对 MV4-11 细胞进行了研究，表明该化合物可以阻止 G1 细胞周期并引发细胞凋亡。估计42的肝毒性和心脏毒性的风险较低。这些发现值得进一步研究42作为靶向癌症治疗剂。
