A novel series of potent and selective IKK2 inhibitors
摘要:
A novel series of ammopyrimidine IKK2 inhibitors have been developed which show excellent in vitro inhibition of this enzyme and good selectivity over the IKK1 isoform. The relative potency and selectivity of these compounds has been rationalized using QSAR and structure-based modelling. (C) 2003 Elsevier Ltd. All rights reserved.

facile access to a diverse set of analogs from common late stage intermediates. Detailed examination of the amine substituents at the C2' position of the pyrimidine and C7 position of the core pyrazolopyridine is described. The antiviral data suggests that non-polar amines are preferred for optimal activity. Additionally, the 2' position has been shown to require an NH group to retain activity levels similar
n-4-yl)pyridines undergo C–H activation at the phenyl ring in the ortho position to the amine nitrogen atom when reacted with (PhCN)2PdCl2 and finally form N,N,C-coordinated palladium(II) complexes in high yields. Five differently substituted complexes were synthesized and characterized by spectroscopy and X-ray structure analysis. The reaction mechanism for the formation of these complexes was elucidated
2-(2-Phenylaminopyrimidin-4-yl) 吡啶与 (PhCN)2PdCl2 反应时,在苯环胺氮原子邻位发生 C-H 活化,最终形成 N,N,C 配位钯 (II) ) 高产率的配合物。合成了五种不同取代的配合物,并通过光谱学和 X 射线结构分析对其进行了表征。通过动力学实验阐明了形成这些配合物的反应机理,从而可以计算出配合物形成的活化参数。

To develop multikinase inhibitors with dual PLK1/VEGF-R2 inhibitory activity, the d-annulated 1-benzazepin-2-one scaffold present in the paullone family of kinase inhibitors was investigated as a general structure template suitable for anchoring annulated heterocycles at the hinge region of the ATP binding site. For this purpose, the indole substructure of the paullones was replaced by other nitrogen containing heteroaromatics. The designed scaffolds were synthesized and tested on the indicated kinases. The 2-anilino-5.7-dihydro-6H-pyrimido[5,4-d][1]benzazepin-6-ones were found to be VEGF-R2 inhibitors with selectivity against the insulin receptor kinase. The attachment of a methoxy group to the 9-position of the scaffold led to additional PLK1 inhibitory activity, which was explained by an alternative binding mode of the 9-methoxy derivatives. Selected members of the compound class inhibited the VEGF-R2 autophosphorylation in human umbilical vein endothelial cells, the sprouting of human umbilical vein endothelial cell speroids, and the proliferation of diverse cancer cell lines.

inhibitors of Aurora A kinase and VEGF receptor kinases. Crystal structures of two representatives of the new chemotype in complex with Aurora A showed the ligand orientation in the ATP binding pocket and provided the basis for rational structural modifications. Congeners with attached sulfamide substituents retained Aurora A inhibitoryactivity. In vitro screening of two members of the newkinase inhibitor
