hypothesized that transient activation of c-Abl kinase via displacement of the N-terminal autoinhibitory "myristoyl latch", may lead to an increased hematopoietic stem cell differentiation. This would increase the numbers of circulating neutrophils and so be an effective treatment for chemotherapy-induced neutropenia. This paper describes the discovery and optimization of a thiazole series of novel small molecule
Abelson激酶(c-Abl)是一种普遍表达的非受体酪氨酸激酶,在细胞分化和存活中起关键作用。据推测,通过N-末端自抑制“肉豆蔻酰闩锁”的移位,瞬时激活c-Abl激酶可能导致造血干细胞分化增加。这将增加循环中性粒细胞的数量,因此是化疗诱发的中性粒细胞减少症的有效治疗方法。本文介绍了噻唑系列新型小分子c-Abl激活剂的发现和优化,该试剂最初通过高通量筛选得以鉴定。随后,利用片段筛选筛选方法开发的二氢吡唑类似物的改善的理化特性,进行了脚手架跳,并提供了有效的,可溶的,具有细胞活性的c-Abl活化剂,
