  发现具有更高溶解度的有效Pan-Raf抑制剂以克服耐药性

  摘要：

  尽管激酶抑制剂在肿瘤学和炎性疾病中有各种应用，但耐药性的出现仍然仍然是实现癌症治疗中长期缓解的主要障碍。为了克服IIB型BRaf V600E选择性抑制剂vemurafenib诱导的耐药性，并进一步改善其抗增殖活性，设计了一种基于吡咯并[2,3- d ]嘧啶支架的新型IIA Pan-Raf抑制剂Ia – Io，并在这项工作中进行了评估。在本文中，我们试图通过增加目标化合物的溶解度来改善它们的细胞效力。其中，Il，其溶解度为0.107 mg / mL，显示出对维拉非尼耐药性癌细胞（包括BRaf WT表型黑色素瘤SK-MEL-2和BRaf V600E表型结直肠癌HT-29细胞系）具有良好的细胞活性。基于良好的溶解度，与索拉非尼相比，II具有良好的代谢稳定性，并在大鼠中具有良好的药代动力学特征。至于生物学机制研究，II在A375和SK-Mel-2细胞中具有与我们先前的P-2相似的P-ERK激酶抑制

  Herein, we describe the design and characterization of a series of compounds I-01–I-22, based on a pyrimidine scaffold with DFG-out conformation as Pan-Raf inhibitors. Among them, I-15 binds to all Raf protomers with IC50 values of 12.6 nM (BRafV600E), 30.1 nM (ARaf), 19.7 nM (BRafWT) and 17.5 nM (CRaf) and demonstrates cellular activity against BRafWT phenotypic melanoma and BRafV600E phenotypic colorectal

  By combining the scaffolds of UI-125 and Sorafenib, a series of bis-aryl ureas and amides based on 2-amino-3-purinylpyridine moiety were designed and synthesized as novel DFG-out B-Raf(V600E) inhibitors. Among them, 20c-e, 20g and 21h displayed potent antiproliferative activities against melanoma A375 (B-Raf(V600E)) cell lines with IC50 values of 3.190, 2276, 1.856, 1.632 mu M and 1.839 mu M, respectively, comparable with the positive control Vemurafenib (IC50 = 3.32 mu M). Selected compounds were tested for the ERK inhibition in human melanoma A375 (B-Raf(V600E)) and SK-MEL-2 (B-Raf(WT)) cell lines by Western blot. The results revealed that our compounds inhibited the proliferation of melanoma A375 cells (B-Raf(V600E)) through ERK pathway, without paradoxical activation of ERK in melanoma SK-MEL-2 cells (B-Rat(WT)). Eventually, 20g and 21h were selected to confirm their inhibitory effects on tumor growth in A375 xenograft models in mice. Compound 20g exhibited equivalent antitumor efficacy in vivo (T/C = 44.37%), compared to Sorafenib (T/C = 37.35%), by 23-day repetitive administration of a single dose of 50 mg/kg without significant body weight loss.

• Potent Pan-Raf and Receptor Tyrosine Kinase Inhibitors Based on a Cyclopropyl Formamide Fragment Overcome Resistance

  While selective BRaf(V600E) inhibitors have been proven effective clinically, acquired resistance rapidly develops through reactivation of the mitogen-activated protein kinase (MAPK) pathway, Simultaneous targeting of multiple nodes in the pathway offers the prospect of enhanced efficacy as well as reduced potential for acquired resistance. Replacement pyridine group of Y-1 by a cyclopropyl formamide group afforded I-01 as a novel multitargeted kinase inhibitor template. I-01 displayed enzyme potency against Pan-Raf and receptor tyrosine kinases (RTKs). Based on the binding mode of I-01, analogues I-02-1-18 were designed and synthesized. The most promising compound I-16 potently inhibits subtypes of Rafs with IC50 values of 3.49 (BRaf(V600E)), 8.86 (ARaf), 5.78 (BRaf(WT)), and 1.65 nM (CRaf); respectively. I-16 not only exhibit comparable antiproliferative activities with positive control compounds against HepG2, SW579, MV4-11, and COLO205 cell lines, but also suppress the proliferation of melanoma SK-MEL-2 harboring overexpressed BRaf(WT) with IC50 values of 0.93 mu M. The Western blot results for: the ERK inhibition in human melanoma SK-MEL-2 cell lines show that I-16 inhibits the proliferation of SK-MEL-2 cell lines without paradoxical activation of ERK, which support the hypothesis that the inhibition of Pan-Raf and RTKs might be a tractable strategy to overcome the resistance of melanoma induced by the therapy with the current selective BRar(V600E) inhibitors..
