受体酪氨酸激酶 Axl 在促进癌症进展、转移和耐药性中发挥重要作用,并已被确定为抗癌治疗的有希望的靶点。我们从低微摩尔效力化合物9开始,使用分子建模辅助结构优化来发现化合物13c ,这是一种高效且可口服生物利用的 Axl 抑制剂。选择性分析表明, 13c可以抑制众所周知的致癌激酶 Met,其抑制 Axl 超家族激酶的效力相同。化合物13c显着抑制细胞Axl和Met信号传导,抑制Axl和Met驱动的细胞增殖,并抑制Gas6/Axl介导的癌细胞迁移或侵袭。此外, 13c在 Axl 驱动和 Met 驱动的肿瘤异种移植模型中表现出显着的抗肿瘤功效,在耐受良好的剂量下导致肿瘤停滞或消退。所有这些有利的数据使13c成为癌症治疗的有前途的候选药物。
1-Oxo-3-aryl-1H-indene-2-carboxylic acid derivatives as selective inhibitors of fibroblast growth factor receptor-1 tyrosine kinase
摘要:
Fibroblast growth factor receptor (FGFr) mediated signal transduction is implicated in vascular proliferative diseases and some cancers. We have identified methyl 1-oxo-3-phenyl-1H-indene-2-carboxylic ester as a small molecule inhibitor of the tyrosine kinase activity of FGFr-1, (IC50 = 5.1 mu M). We report here the synthesis and structure-activity studies about this template core. Additionally, screening of this series against a panel of tyrosine kinases shows selective inhibition of FGFr.

Because of the formidable development of the asymmetric reduction of tetrasubstituted olefins, an effective method is in urgent demand. Herein, through the biomimetic protocol of the coenzyme NAD(P)H, the reduction of tetrasubstituted olefin 2,3-substituted 1H-inden-1-ones has been successfully realized with the catalytic chiral NAD(P)Hmodel CYNAM, which is hard to bring about via the common rhodium
The rhodium(I)-catalyzed reaction of alkynes with 2-bromophenylboronic acids in the presence of paraformaldehyde resulted in a CO gas-free carbonylative cyclization, yielding indenone derivatives. [RhCl(BINAP)]2 and [RhCl(cod)]2 were responsible for the decarbonylation of formaldehyde and the subsequent carbonylation of alkynes with 2-haloboronic acids, respectively, leading to efficient whole carbonylation

This invention discloses methods and agents for modulating the differentiation potential and/or proliferation of preadipocytes. More particularly, the present invention discloses methods and agents for modulating a fibroblast growth factor (FGF) signalling pathway, especially the FGF-1 or FGF-2 signalling pathway, for treating or preventing adiposity-related conditions including, but not limited to, obesity, lipoma and lipomatosis.
reaction of alkynes with 2-bromophenylboronic acids under nitrogen gives naphthalene derivatives, in which two molecules of alkynes are incorporated. A vinylrhodium complex similar to II can also be generated by a different route by employing 2-bromophenyl(trimethylsilyl)acetylene and arylboronic acids in the presence of Rh(I) complex as the catalyst, resulting in the formation of indenones. The reaction
