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.

A subject of the present Application is novel derivatives of benzimidazole and imidazopyridine which have a good affinity for certain sub-types of melanocortin receptors, in particular the MC4 receptors. They are particularly useful for treating pathological conditions and diseases in which one or more melanocortin receptors are involved. The invention also relates to pharmaceutical compositions containing said products.

The serine protease urokinase (uPa) has been implicated in the progression of both breast and prostate cancer. Utilizing structure based design, the synthesis of a series of substituted 4-[2-amino- 1,3-thiazolyl]-thiophene-2-carboxamidine is described. Further optimization of this series by substitution of the terminal amine yielded urokinase inhibitors with excellent activities. (C) 2001 Elsevier Science Ltd. All rights reserved.
