  Identification and Optimization of New Dual Inhibitors of B-Raf and Epidermal Growth Factor Receptor Kinases for Overcoming Resistance against Vemurafenib

  摘要：

  Epidermal growth factor receptor (EGFR) amplification has been demonstrated to be critical for the inherent and/or acquired resistance against current B-Raf(V600E) inhibitor therapy for melanoma and colorectal cancer patients. We describe the discovery and structure-activity relationship study of a series of 1H-pyrazolo[3,4-b]pyridine-5-carboxamide analogues as novel dual inhibitors of EGFR and B-Raf(V600E) mutant. One of the most promising compounds, 6a, potently inhibited both of the kinases with IC50 values of 8.0 and 51 nM, respectively. The compound also strongly suppressed the proliferation of a panel of intrinsic and acquired resistant melanoma and/or colorectal cancer cells harboring overexpressed EGFR with submicromolar IC50 values. Further mechanism investigation revealed that 6a could sustainably inhibit the activation of the MAPK path way in the resistant SK-MEL-28 PR30 melanoma cancer cells and WiDr colorectal cancer cells with EGFR amplification. Our results support the hypothesis that the EGFR/B-Raf(V600E) dual inhibition might be a tractable strategy to overcome the intrinsic and acquired resistance of melanoma and/or colorectal cancers against the current B-Raf(V600E) inhibitor therapy.

  摘要：

  同时靶向所有Raf同工型提供了增强的功效以及降低的抗药性的前景。本文描述了一系列具有强力泛肽抑制剂的具有DFG-out构象的嘧啶支架的发现和表征。其中，具有优异泛泛效能的I-41表现出对BRafWT表型黑素瘤和BRafV600E表型结肠细胞的抑制活性。Western blotting结果显示，人黑素瘤SK-Mel-2细胞系中Erk的抑制作用表明I-41抑制了SK-Mel-2细胞的增殖而没有Erk的反常激活，这支持I-41可能成为良好的候选化合物。克服黑素瘤对当前BRafV600E抑制剂疗法的耐药性。I-41在大鼠中也具有良好的药代动力学特征。合成，SAR，线索选择，

  Signaling via the receptor tyrosine kinase CSF1R is thought to play an important role in recruitment and differentiation of tumor-associated macrophages (TAMs). TAMs play pro-tumorigenic roles, including the suppression of anti-tumor immune response, promotion of angiogenesis and tumor cell metastasis. Because of the role of this signaling pathway in the tumor microenvironment, several small molecule CSF1R kinase inhibitors are undergoing clinical evaluation for cancer therapy, either as a single agent or in combination with other cancer therapies, including immune checkpoint inhibitors. Herein we describe our lead optimization effort that resulted in the identification of a potent, cellular active and orally bioavailable bis-amide CSF1R inhibitor. Docking and biochemical analysis allowed the removal of a metabolically labile and poorly permeable methyl piperazine group from an early lead compound. Optimization led to improved metabolic stability and Caco2 permeability, which in turn resulted in good oral bioavailability in mice. (C) 2017 Elsevier Ltd. All rights reserved.
