Recently the insuline-like growth factor receptor (IGF-1R) emerged as a promising target structure for the development of novel anti-cancer agents. IGF-1R plays a central role in both tumour progression and resistance development against anti-cancer drugs. We discovered 1-aza-9-oxafluorene derivatives as novel lead structures with submicromolar activities against IGF-1R. Structure-activity relationships (SARs) on a series of related receptor tyrosine kinases (RTKs) are discussed in the context of available crystal structures. A preliminary selectivity-profiling is demonstrated for the first compound series. Anti-proliferative tumour cell line screening studies yielded one candidate as a promising cytostatic agent without significant toxic effects. (C) 2010 Elsevier Ltd. All rights reserved.
Discovery of dually acting small-molecule inhibitors of cancer-resistance relevant receptor tyrosine kinases EGFR and IGF-1R
and pyrrolo[2,3-b]pyridines with a 4-benzylamine substitution have been evaluated as inhibitors of the epidermal growth factor receptor (EGFR). Substituent effects on the determined proteinkinase affinity have been discussed based on varied benzylamine residues at the differently substituted molecular scaffolds. Docking studies were carried out in order to explore the potential binding modes of the
