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 generally to novel substituted oxindole compounds and compositions. Such compounds and compositions have utility as pharmacological agents in treating diseases or conditions alleviated by the inhibition or antagonism of protein kinase activated signalling pathways. In particular, the present invention relates to a series of substituted oxindole compounds, which exhibit protein tyrosine kinase and protein serine/threonine kinase inhibition, and which are useful in inhibiting tumor growth via inhibition of such kinases as well as protecting a patient undergoing chemotherapy from chemotherapy induced alopecia.
A compound represented by the formula (I):
wherein each symbol is as described in the SPECIFICATION, or a salt thereof has a PDE2A inhibitory action, and is useful as a prophylactic or therapeutic drug for schizophrenia, Alzheimer's disease and the like.
Substituted aza-oxindole derivatives useful as cyclin dependent kinase 11 inhibitors, for preventing/reducing the severity of epithelial cytotoxicity side-effects (e.g., alopecia, plantar-palmar syndrome, mucositis) induced by chemoptherapy and/or radiation therapy in a patient receiving such therapy.
The present invention relates generally to novel amine substituted oxindole compounds and compositions. Such compounds and compositions have utility as pharmacological agents in treating diseases or conditions alleviated by the inhibition or antagonism of protein kinase activated signalling pathways in general, and in particular in the pathological processes which involve aberrant cellular proliferation, such as tumor growth. In particular, the present invention relates to a series of substituted oxindole compounds, which exhibit protein tyrosine kinase and protein serine/threonine kinase inhibition, and which are useful in inhibiting tumor growth via inhibition of tumor-related angiogenesis.
Compounds of the invention are useful in inhibiting thrombin and associated thrombotic occlusions having the following structure:
1
or a pharmaceutically acceptable salt thereof.
