Novel benzofuran-3-one indole inhibitors of PI3 kinase-α and the mammalian target of rapamycin: Hit to lead studies
摘要:
A series of benzofuran-3-one indole phosphatidylinositol-3-kinases (PI3K) inhibitors identified via HTS has been prepared. The optimized inhibitors possess single digit nanomolar activity against p110 alpha (PI3K-alpha), good pharmaceutical properties, selectivity versus p110 gamma (PI3K-gamma), and tunable selectivity versus the mammalian target of rapamycin ( mTOR). Modeling of compounds 9 and 32 in homology models of PI3K-alpha and mTOR supports the proposed rationale for selectivity. Compounds show activity in multiple cellular proliferation assays with signaling through the PI3K pathway confirmed via phospho-Akt inhibition in PC-3 cells. (C) 2010 Elsevier Ltd.

3-乙烯基吲哚对吡啶并[2,3- a ]-,吡啶并[4,3- a ]-和噻吩并[2,3- a ]-咔唑的光化学电环化:设计,合成,DNA结合和抗肿瘤细胞毒性
摘要:
在DNA配体的设计和合成过程中,合成了一些新的戊烯退火的咔唑。作为铅结构,考虑了插入的四环体系吡啶并[2,3- a ]-和吡啶并[4,3- a ]-咔唑,在一种情况下考虑了噻吩并[2,3- a ]-咔唑。将二烷基氨基酰胺链引入平面发色体系,目的是产生较小的凹槽结合性能。通过NCI抗肿瘤筛选检查了某些化合物的细胞毒性。此外,进行了生物物理和生化研究,以便获得有关此新系列分子的DNA结合特性和对DNA相关功能酶的抑制作用的一些信息。

atroposelective synthesis of macrocyclic planar-chiral indoles via NHC-catalyzed intramolecular macrocyclization is reported. In addition, the indole-based macrocycles bearing both planar and axial chirality have also been constructed via kinetic resolution. Importantly, these obtained planar-chiral macrocycles provide additional possibilities to develop novel catalysts or ligands, as well as newreactions.

The present invention is directed to a method for the synthesis of a bi-functional complex comprising a molecule part and an identifier oligonucleotide part identifying the molecule part. A part of the synthesis method according to the present invention is preferably conducted in one or more organic solvents when a nascent bi-functional complex comprising an optionally protected tag or oligonucleotide identifier is linked to a solid support, and another part of the synthesis method is preferably conducted under conditions suitable for enzymatic addition of an oligonucleotide tag to a nascent bi-functional complex in solution.
Creation of New Promoters for Plant’s Root Growth: Its Application for the Syntheses of Vulcanine and Borreline, and for Combating Desertification at Gobi Desert in Inner Mongolia
Various new 2-substituted indole-3-carbaldehydes are prepared. Structurally related alkaloids, vulcanine and borreline, are synthesized as well. Among the compounds, 2-haloindole-3-carbaldehydes are found to be potent promoters of plant's root growth. Its successful preliminary application is reported for making Gobi desert in Inner Mongolia full of plant.
