  A novel and efficient NHC-catalyzed [3+3] annulation of enals with pyrrol-4-ones was developed, thus providing the dihydropyrano[3,2-b]pyrrol-5-one core structures with broad scope and good to excellent enantioselectivities. Notably, this strategy could also expand to the synthesis of axially chiral compounds and polysubstituted indoles.

  we report on a new chemical class of 5-heteroaryl-3-carboxamido-2-substituted pyrroles (1A) that offers advantages of chemistry diversification and synthetic simplification. This work led to the identification of compound 18, with biochemical data and ADME profile similar to those of compound 1 but characterized by superior efficacy in an in vivo model. Derivative 18 represents a new lead compound worthy

  Cdc7丝氨酸/苏氨酸激酶是真核生物中DNA合成的关键调节剂。通过si RNA或原型小分子对Cdc7的抑制在肿瘤细胞中引起p53独立凋亡，同时可逆地阻止初级成纤维细胞的细胞周期进程。这暗示着Cdc7激酶可以被认为是抗癌治疗的潜在靶标。我们先前曾报道吡咯并吡啶并酮（例如1）是Cdc7激酶的有效和选择性抑制剂，具有良好的细胞效力和体外ADME特性，但药代动力学不理想。在这里我们报告了一种新的化学类别的5-杂芳基-3-羧酰胺基-2-取代的吡咯（1A）具有化学多样化和合成简化的优势。这项工作导致了化合物18的鉴定，其生化数据和ADME谱与化合物1相似，但在体内模型中具有优越的功效。衍生物18代表一种新的先导化合物，值得进一步研究，以最终确定出临床候选药物。
