This paper describes the Heck cross-coupling reaction of 3-iodoindazoles with methyl 2-(acetylamino)acrylate as a general route to new dehydro 2-azatryptophans and protected amino acid derivatives after catalytic hydrogenation.
Design, synthesis, and Structure–Activity Relationships (SAR) of 3-vinylindazole derivatives as new selective tropomyosin receptor kinases (Trk) inhibitors
by the US FDA approval of small molecular Trk inhibitors Larotrectinib (1, LOXO-101) and Entrectinib (2). However, gene mutation mediated resistance becomes a major challenge for Trk inhibitor therapies. Herein, we report the design, synthesis and Structure–ActivityRelationship investigation of a series of 3-vinylindazole derivatives as new Trk inhibitors with low nanomolar potencies.

神经营养受体酪氨酸激酶(NTRK)融合是多种成年和小儿肿瘤的致癌驱动因子,已通过美国FDA批准的小分子Trk抑制剂Larotrectinib(1,LOXO-101)和ENTrectinib(2)验证。然而,基因突变介导的耐药性成为Trk抑制剂治疗的主要挑战。在本文中,我们报告了一系列3-乙烯基吲唑衍生物作为新型Trk抑制剂的设计,合成和结构-活性关系研究,该抑制剂具有低纳摩尔浓度。有代表性的化合物,7MB,结合与TrkA / B / C与ķ d 1.6,3.1和4.9纳米的值,并抑制它们的激酶功能与IC 50值分别为1.6、2.9和2.0 nM,但在KINOMEscan选择性研究中,对于大多数403种野生型激酶的大多数而言,其效价显然较低。该化合物还有效地抑制了BaF3细胞用NTRK融合与IC稳定转化的面板的增殖50在低nM范围内的值。此外,该化合物对具有NTRK1-G667C或NTRK3-G696A突变且IC

The present invention is directed to indazole compounds which are potent inhibitors of LRRK2 kinase and useful in the treatment or prevention of diseases in which the LRRK2 kinase is involved, such as Parkinson's Disease. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases in which LRRK2 kinase is involved.

Leucine Rich Repeat Protein Kinase 2 gene (LRRK2) are the most common genetic causes of Parkinson's Disease (PD). The G2019S mutation is the most common inherited LRRK2 mutation, occurs in the kinase domain, and results in increased kinase activity. We report the discovery and development of compound 38, an indazole-based, G2019S-selective (>2000-fold vs. WT) LRRK2 inhibitor capable of entering rodent

The present invention provides indazole derivatives or their pharmaceutically acceptable salts or stereoisomers having the structure shown in formula (I), and their pharmaceutical compositions and applications thereof. Such compounds can be used as protein kinase inhibitors, which can effectively inhibit the activity of tropomyosin receptor kinase (TRK) protein kinase and can inhibit the proliferation, migration and invasion of a variety of tumor cells.
