Identification of novel, selective and potent Chk2 inhibitors
摘要:
A series of isothiazole carboxamidine compounds were synthesized and discovered as novel and selective inhibitors for Chk2. They are not active against the related Chk1 kinase. The structure-activity relationship studies were performed on the scaffold, and enzymatic kinetic analysis showed they are simple ATP competitive inhibitors with K-i values as low as 11 nM for Chk2. Computer modeling studies were employed to comprehend the mechanism of action and SAR of these compounds. (c) 2006 Elsevier Ltd. All rights reserved.
Die Erfindung betrifft die Verwendung von Genveränderungen im humanen Gen CHK2 (CHEK2), das für die Checkpointkinase 2 kodiert, zur Vorhersage des Risikos und des Verlaufs von Krebserkrankungen und zur Vorhersage des Ansprechens auf pharmakologische oder nicht-pharmakologische Therapiemaßnahmen zur Behandlung von Krebserkrankungen sowie zur Vorhersage unerwünschter Arzneimittelwirkungen. Ferner betrifft die Erfindung die Bereitstellung von einzelnen Genvarianten, mit deren Hilfe weitere für die oben genannten Zwecke verwendbaren Genveränderungen detektiert und validiert werden können. Solche Genveränderungen können darin bestehen, dass im Promotor von CHK2 an Position -7161 eine Substitution von Guanin zu Adenin vorliegt, an Position -7235 eine Substitution von Cytosin zu Guanin, an Position -10532 eine Substitution von Guanin zu Adenin vorliegt oder an Position -10621 bis -10649 eine Deletion von 29 Basenpaaren vorliegt.

This invention provides compounds of Formula I
which are inhibitors of Chk2 and are useful as a radiation protection agents in anticancer radiotherapy. A method of modulating Chk2 in vitro includes treating a substrate with Chk2 in the presence of compounds of formula I. A method of making a compound of formula I includes: a) forming a biaryl amine having an amino (NH
2
) group; b) converting the amino group to an isothiocyanate group; c) adding a cyanoacetamide to said isothiocyanate group to form a thioamide adduct; d) cyclizing said thioamide adduct to form an isothiazole having a cyano group; and e) adding an amine to said cyano group to form a carboxamidine group.

The invention relates to the use of gene modifications in the human gene CHK2 (CHEK2), which encodes the checkpoint kinase 2, for predicting the risk and progression of cancer diseases, for predicting the response to pharmacological or non-pharmacological therapeutic measures for treating cancer diseases, and for predicting undesired effects of drugs. The invention further relates to the provision of individual gene variants with the help of which further gene modifications that can be used for the aforementioned purposes can be detected and validated. Such gene modifications can comprise a substitution of adenine for guanine in position -7161 in the promoter of CHK2, a substitution of guanine for cytosine in position -7235, a substitution of adenine for guanine in position -10532, or a deletion of 29 base pairs in positions -10621 to -10649.
