  The present disclosure relates to bifunctional compounds, ULM— L—PTM, which find utility as modulators of Rapidly Accelerated Fibrosarcoma (RAF, such as c-RAF, A- RAF and/or B-RAF; the target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a Von Hippel-Lindau, cereblon, Inhibitors of Apotosis Proteins or mouse double-minute homolog 2 ligand which binds to the respective E3 ubiquitin ligase and on the other end a moiety which binds the target protein RAF, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aggregation or accumulation of the target protein, or the constitutive activation of the target protein, are treated or prevented with compounds and compositions of the present disclosure.

  cells. To date, many small molecule approaches are under investigation to target CRAF, yet kinase-selective and cellular potent inhibitors remain challenging to identify. Herein, we describe 14 (RAF709) [Aversa, Biaryl amide compounds as kinase inhibitors and their preparation. WO 2014151616, 2014], a selective B/C RAF inhibitor, which was developed through a hypothesis-driven approach focusing on drug-like

  RAS致癌基因已涉及超过30％的人类癌症，均代表高度未满足的医疗需求。在基因工程小鼠模型和人类肿瘤细胞中已经建立了对KRAS突变肿瘤中对CRAF激酶的精确依赖性。迄今为止，许多针对CRAF的小分子方法正在研究中，但是激酶选择性抑制剂和细胞有效抑制剂的鉴定仍然具有挑战性。在此，我们描述14（RAF709）[Aversa，联芳酰胺化合物作为激酶抑制剂及其制备方法。WO 2014151616， [2014]，一种选择性的B / C RAF抑制剂，通过假设驱动的方法开发，该方法侧重于药物样特性。在药物化学研究中遇到的一个关键挑战是在KRAS突变肿瘤细胞系中保持良好的溶解度和有效的细胞活性（pMEK的抑制和增殖）之间的平衡。我们研究了铅分子7的小分子晶体结构，并假设破坏晶体堆积会提高溶解度，从而导致从N-甲基吡啶酮转变为四氢吡喃基氧基-吡啶衍生物。在KRAS突变异种移植模型中，有14种被证明是可溶的，激酶选择性的和有效的。
