Small Molecule Reversible Inhibitors of Bruton’s Tyrosine Kinase (BTK): Structure–Activity Relationships Leading to the Identification of 7-(2-Hydroxypropan-2-yl)-4-[2-methyl-3-(4-oxo-3,4-dihydroquinazolin-3-yl)phenyl]-9H-carbazole-1-carboxamide (BMS-935177)
摘要:
Bruton's tyrosine,kinase (BTK) belongs to the TEC family of nonreceptor tyrosine kinases and plays a critical role in multiple cell types responsible for numerous auto-immune diseases. This article will detail the structure-activity relationships (SARs) leading to a novel second generation series of potent and, selective reversible carbazole inhibitors of BTK. With an excellent pharmacokinetic profile as well as demonstrated in vivo activity and an acceptable safety profile, 7-(2-hydroxypropan-2-yl)-4-[2-methyl-3-(4-oXo-3,4-dihydroquinazdlin-3-yl)phenyl]-9H-carbazole-1-carboxarnide 6 (BMS-935177) was selected:to advance into clinical development.

The use of amide carbonylgroups of substrates as weakly coordinating directinggroups has received a significant amount of attention. Recently, difluoromethylene alkynes have been successfully used in fluorination reactions, resulting in the preparation of various fluorine-containing compounds. This work describes a [4+2] annulation method for creating a range of fluorinated quinolino[2,1-b]quinazolinone
使用底物的酰胺羰基作为弱配位导向基团已受到广泛关注。近年来,二氟亚甲基炔已成功用于氟化反应,从而制备了各种含氟化合物。这项工作描述了一种 [4+2] 成环方法,用于制备一系列氟化喹啉并[2,1- b ]喹唑啉酮衍生物。该衍生物是通过 Rh(III) 催化的 3-苯基喹唑啉酮和偕二氟亚甲基炔的级联环化形成的。
