of RET kinase has been found in several neoplastic diseases, like medullary thyroid carcinoma, multiple endocrine neoplasia, papillary thyroid carcinoma, and non-small-cell lung cancer. Currently approved RETinhibitors were not originally designed to be RETinhibitors, and their potency against RET kinase has not been optimized. Hence, novel compounds able to inhibit both wild-type RET (wtRET) and
RET激酶的致癌激活已在多种肿瘤疾病中发现,如甲状腺髓样癌,多发性内分泌肿瘤,甲状腺乳头状癌和非小细胞肺癌。目前批准的RET抑制剂最初并未设计为RET抑制剂,而且它们对RET激酶的效能尚未优化。因此,需要能够抑制野生型RET(wt RET)及其突变体(例如V804M RET)的新型化合物。本文中,我们介绍了新型亚微摩尔wt RET / V804M RET抑制剂N-(2-氟-5-三氟甲基苯基)-N'-4'-[(2''-苯甲酰胺基)吡啶的开发和初步评估从我们先前鉴定的4-苯胺基嘧啶命中化合物开始,具有4-苯胺基吡啶结构的-4”-基氨基]苯基}脲(69)。

A highly site-selective amidation reaction of substituted 2,4-dichloroazines is reported. Palladium acetate/1,1′-bis(diphenylphosphino)ferrocene (dppf) was identified as the optimal catalyst system, producing >99:1 C-2/C-4 selectivity for most examples. The generality of this transformation was demonstrated through a survey of a diverse amide/substituted 2,4-dichloroazine scope, leading to the preparation
