anticancer drug design. A novel series of pyrimidylpyrrole ERK inhibitors has been identified. Discovery of a conformational change for lead compound 2, when bound to ERK2 relative to antitarget GSK3, enabled structure-guided selectivity optimization, which led to the discovery of 11e, a potent, selective, and orallybioavailableinhibitor of ERK.
Compounds having the formula I wherein R
2
, X and Z as defined herein are inhibitors of ERK kinase. Also disclosed are compositions and methods for treating hyperproliferative disorders.

adenylyltransferase inhibitors (PPAT, CoaD). Following several rounds of optimization two promising lead compounds were identified: triazolopyrimidinone 3 and 4-azabenzimidazole 4. Here we disclose our efforts to further optimize these two leads for on-target potency and Gram-negative cellular activity. Enabled by a robust X-ray crystallography system, our structure-based inhibitor design approach delivered
在前面的手稿中[Moreau et al。2018,10.1021 / acs.jmedchem.7b01691]我们描述了一个成功的基于片段的铅发现(FBLD)策略用于细菌磷酸泛酰腺苷酰转移酶抑制剂(PPAT,COAD)的发现。经过几轮优化,确定了两个有前途的先导化合物:三唑并嘧啶酮3和4-氮杂苯并咪唑4。在这里,我们公开了我们的工作,以进一步优化针对靶点效力和革兰氏阴性细胞活性的这两种线索。借助强大的X射线晶体学系统,我们基于结构的抑制剂设计方法可提供具有比其各自片段起始点大4–5个数量级的生化潜能的化合物。通过对细菌渗透性和理化性质的观察指导其他优化,这最终导致鉴定出具有针对野生型大肠杆菌的细胞活性的PPAT抑制剂。

developed. Indole nucleophiles prepared with MeMgCl in the presence of CuCl reacted with chiral cyclic sulfamidates almost exclusively at the C3-position of indole to form a variety of α- and/or β-substituted chiral tryptamines in good yield with excellent regioselectivity. The utility of this simple alkylation process has been demonstrated with the practical synthesis of two biologically active targets
The invention provides novel quinazoline carboxamide azetidine compounds according to Formula (I) and use for the treatment of hyperproliferative diseases, such as cancer.
