  人组织蛋白酶K的一类新型非肽联芳基抑制剂。

  摘要：

  一种新的非肽联芳基化合物系列被鉴定为组织蛋白酶K的有效抑制剂和可逆抑制剂。已知氨基乙腈二肽1的P2-P3酰胺键被苯环取代，从而形成了与组织蛋白酶相比仍保持效力的联芳基系列K和对其他组织蛋白酶显示出改善的选择性。该系列中的结构修饰导致鉴定了化合物（R）-2，这是一种有效的人组织蛋白酶K抑制剂（IC（50）= 3 nM），相对于组织蛋白酶B（IC（50）= 3950 nM），L（ IC（50）= 3725 nM），S（IC（50）= 2010 nM）。在涉及兔破骨细胞和牛骨的体外测定中，化合物（R）-2以95 nM的IC（50）抑制骨吸收。结果表明，与某些半胱氨酸蛋白酶的肽腈抑制剂不同，组织蛋白酶K不会将（R）-2的腈部分转化为相应的酰胺3。这表明这类非肽腈抑制剂不太可能被半胱氨酸蛋白酶水解。此外，显示化合物（R）-2对组织蛋白酶K的抑制是完全可逆的，并且不是时间依赖性的。为了证明化合物（R）-2在体内的功效，将其以20

  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.
