用于心力衰竭的一类新型治疗药物,高效和选择性的GRK2抑制剂,在体外研究中表现出增强的β-肾上腺素信号传导能力。HTS将衍生物5和1,2,4-三唑衍生物24a鉴定为命中化合物。新一代的脚手架和所有部分的SAR研究都产生了带有N-苄基羧酰胺部分的4-甲基-1,2,4-三唑衍生物,对GRK2的活性很高,对其他激酶的选择性更高。在亚型选择性方面,这些化合物对GRK1、5、6和7表现出足够的选择性,并且对GRK3具有几乎相同的抑制作用。我们的药物化学努力导致发现了115h(GRK2 IC 50= 18 nM),获得了与人GRK2和GRK2抑制剂的共晶体结构,该抑制剂增强了β-肾上腺素能受体(βAR)介导的cAMP积累,并防止了用异丙肾上腺素处理过的表达β2AR的HEK293细胞中βAR的内在化。因此,115h似乎是心力衰竭治疗的一种新型疗法。

The present invention provides a compound of formula (I) or a pharmaceutically acceptable salt thereof wherein A is hydrogen, C1-4alkyl, C3-6cycloalkyl, C1-3alkoxy, C1-3alkoxy C1-4alkyl, C1-2fluoroalkyl, halogen, NR6 R7, optionally substituted heteroaryl (Het), or optionally substituted phenyl, and R1, R2, R3, R4, R5, R6 and R7 are as defined in the description. The compounds or salts are thought to modulate P2X7 receptor function and to be capable of antagonizing the effects of ATP at the P2X7 receptor. The invention also provides the use of the compound or salt in the treatment or prophylaxis of, for example, inflammatory pain, neuropathic pain, visceral pain, rheumatoid arthritis, osteoarthritis or neurodegenerative disorders.

Isoniazid (INH) remains a cornerstone for treatment of drug susceptible tuberculosis (TB), yet the quantitative structure-activity relationships for INH are not well documented in the literature. In this paper, we have evaluated a systematic series of INH analogs against contemporary Mycobacterium tuberculosis strains from different lineages and a few non-tuberculous mycobacteria (NTM).

The present invention relates to new compounds of formula I, to processes for their preparation, to pharmaceutical formulations containing such compounds and to their use in therapy. Such compounds find particular use in the treatment and/or prevention of conditions or diseases which are affected by over-activation of signaling in the Wnt pathway. For example, these may be used in preventing and/or retarding proliferation of tumor cells, for example carcinomas such as colon carcinomas.

The synthesis, SAR, and preclinical characterization of a series of substituted 6,7-dihydro[1,2,4]triazolo[4,3]pyrazin-8(5H)-one P2X7 receptorantagonists are described. Optimized leads from this series comprise some of the most potent human P2X7R antagonists reported to date (IC50s<1nM). They also exhibit sufficient potency and oral bioavailability in rat to enable extensive in vivo profiling. Although
