临床候选N -((1 S)-1-(3-氟-4-(三氟甲氧基)苯基)-2-甲氧基乙基)-7-甲氧基-2-氧代-2,3-二氢吡啶基的发现[2,3- b ] pyrazine-4(1 H)-羧酰胺(TAK-915):一种用于治疗认知障碍的强效,选择性和脑穿透性磷酸二酯酶2A抑制剂。
摘要:
磷酸二酯酶(PDE)2A抑制剂已成为一种新型机制,具有潜在的治疗选择,可通过上调大脑中的环核苷酸来改善精神分裂症或阿尔茨海默氏病的认知功能障碍,从而增强环核苷酸信号通路的作用。本文详细介绍了我们最近公开的吡唑并[1,5- a ]嘧啶前导化合物4b的加速优化过程,从而发现了临床候选药物36(TAK-915),这证明了药效,PDE选择性和有利性的适当组合药代动力学(PK)特性,包括脑部渗透。成功鉴定出36通过应用基于结构的药物设计(SBDD)进一步提高效能和PDE选择性,以及侧重于理化特性以实现大脑渗透的前瞻性设计,实现了这一目标。口服给药36表明,小鼠脑中3',5'-环鸟苷单磷酸(cGMP)水平显着升高,并且在大鼠的新物体识别任务中改善了认知能力。因此,化合物36进入了人类临床试验。

The present invention relates to bifunctional compounds, which find utility as modulators of targeted ubiquitination, especially inhibitors of a variety of polypeptides and other proteins which are degraded and/or otherwise inhibited by bifunctional compounds according to the present invention. In particular, the present invention is directed to compounds, which contain on one end a VHL ligand which binds to the ubiquitin ligase and on the other end a moiety which binds a target protein such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of that protein. The present invention exhibits a broad range of pharmacological activities associated with compounds according to the present invention, consistent with the degradation/inhibition of targeted polypeptides.
In its many embodiments, the present invention relates to a novel class of phenylmorpholine and phenylthiomorpholine compounds useful as α2C adrenergic receptor agonists, pharmaceutical compositions containing the compounds, and methods of treatment, prevention, inhibition, or amelioration of one or more diseases associated with the α2C adrenergic receptor agonists using such compounds or pharmaceutical compositions.

The description relates to cereblon E3 ligase binding compounds, including bifunctional compounds comprising the same, which find utility as modulators of targeted ubiquitination, especially inhibitors of a variety of polypeptides and other proteins which are degraded and/or otherwise inhibited by bifunctional compounds according to the present disclosure. In particular, the description provides compounds, which contain on one end a ligand which binds to the cereblon E3 ubiquitin ligase and on the other end a moiety which binds a target protein such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of that protein. Compounds can be synthesized that exhibit a broad range of pharmacological activities consistent with the degradation/inhibition of targeted polypeptides of nearly any type.
