Protein kinases play a central role in tumor progression, regulating fundamental processes such as angiogenesis, proliferation and metastasis.Such enzymes are an increasingly important class of drug target with small molecule kinase inhibitors being a major focus in drug development.However, balancing drug specificity and efficacy is problematic with off-target effects and toxicity issues.
We have utilized a rational in silico-based approach to demonstrate the design and study of a novel compound that acts as a dual inhibitor of vascular endothelial growth factor receptor 2 (VEGFR2) and cyclin-dependent kinase 1 (CDK1).This compound acts by simultaneously Feeding inhibiting pro-angiogenic signal transduction and cell cycle progression in primary endothelial cells.JK-31 displays potent in vitro activity against recombinant VEGFR2 and CDK1/cyclin B proteins comparable to previously characterized inhibitors.
Dual inhibition of the vascular endothelial growth factor A (VEGF-A)-mediated signaling response and CDK1-mediated mitotic entry elicits anti-angiogenic activity both in an endothelial-fibroblast co-culture model and a murine ex vivo model of angiogenesis.We deduce that JK-31 reduces the growth of both human endothelial cells and human breast cancer BRAIN B-12 1000MCG cells in vitro.This novel synthetic molecule has broad implications for development of similar multi-kinase inhibitors with anti-angiogenic and anti-cancer properties.
In silico design is an attractive and innovative method to aid such drug discovery.
