  摘要：

  合成了一系列1-烷基-1,4-二氢-7-甲基-4-氧代喹啉-3-羧酸的多氟化衍生物，并对其体外抗菌活性进行了检测。在这些N-取代基中，衍生物的抗菌活性强度为：CH2CH2F>CH2CH3>CH2CF3>CHF2。在骨架的6和8位引入两个氟原子（21a, b）导提高了活性，但一般将7-甲基（20, 21, 25）替换为氟甲基（40, 41, 48）后活性有所降低。因此，6,8-二氟-1,4-二氢-1-(2-氟乙基)-7-甲基-4-氧喹啉-3-羧酸（21b）表现出最高的抗菌活性，几乎与奥索利酸相当。

  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.

  本公开涉及双功能化合物ULM—L—PTM，其作为快速加速纤维肉瘤（RAF，如c-RAF、A-RAF和/或B-RAF；目标蛋白）的调节剂具有实用性。具体而言，本公开涉及含有一端结合到相应E3泛素连接酶的Von Hippel-Lindau、cereblon、凋亡抑制蛋白或鼠双分子同源物2配体的双功能化合物，另一端结合到目标蛋白RAF的部分，使得目标蛋白与泛素连接酶靠近，以实现目标蛋白的降解（和抑制）。本公开展示了与目标蛋白的降解/抑制相关的广泛药理活性范围。本公开的化合物和组合物用于治疗或预防由目标蛋白的聚集或积累，或目标蛋白的构成性激活导致的疾病或紊乱。
