  Novel Potent BRAF Inhibitors: Toward 1 nM Compounds through Optimization of the Central Phenyl Ring

  摘要：

  BRAF, a serine/threonine specific protein kinase that is part of the MAPK pathway and acts as a downstream effector of RAS, is a potential therapeutic target in melanoma. We have developed a series of small-molecule BRAF inhibitors based on a 1H-imidazo[4,5-b]pyridine-2(3H)-one scaffold (ring A) as the hinge binding moiety and a number Of Substituted phenyl rings C that interact with the allosteric binding site. The introduction of various groups on the central phenyl ring B combined with appropriate A- and C-ring modifications afford very potent compounds that inhibit (V600E)BRAF kinase activity in vitro and oncogqnic BRAF signaling in melanoma cells. Substitution on the central phenyl ring of a 3-fluoro, a naphthyl, or a 3-thiomethyl group improves activity to yield compounds with an IC50 of 1 nM for purified (V600E)BRAF and nanomolar activity in cells.

  We describe the design, synthesis, and optimization of a series of new inhibitors of V-RAF murine sarcoma viral oncogene homologue B1 (BRAF), a kinase whose mutant form (V600E) is implicated in several types of cancer, with a particularly high frequency in melanoma. Our previously described inhibitors with a tripartite A−B−C system (where A is a hinge binding pyrido[4,5-b]imidazolone system, B is an

  我们描述了一系列新型V-RAF鼠肉瘤病毒癌基因同源物B1（BRAF）抑制剂的设计，合成和优化，该激酶的突变体形式（V600E）与几种类型的癌症有关，发生频率特别高在黑色素瘤中。我们先前所述的具有三方A-B-C系统的抑制剂（其中A是铰链结合吡啶并[4,5- b ]咪唑啉酮系统，B是芳基间隔基团，C是杂芳族基团）对纯化的V600E有效体外进行BRAF，但在伴随的细胞测定中效力较弱。本文评估将不同的芳族杂环取代为基于苯基的C环，作为提高这些抑制剂细胞效价的潜在手段。取代的吡唑，尤其是3-叔丁基-丁基-1-芳基-1 H-吡唑类可增加细胞效能，而对分离的V600E BRAF的效能无不利影响。因此，已经合成了以低纳摩尔浓度抑制V600E BRAF，其在细胞中的下游信号传导的化合物（如通过细胞外调节激酶（ERK）磷酸化的减少来测量）以及突变型BRAF依赖性细胞的增殖。伴随的好处是良好的口服生物利用度和体内高血浆浓度。
