"Inhibitors of IGF-1R
Due to the similarity of the structures of IGF-1R and the insulin receptor, especially in the regions of the ATP binding site and tyrosine kinase regions, synthesising selective inhibitors of IGF-1R is difficult. Prominent in current research are two main classes of inhibitor: 1) Tyrphostins such as AG538 and AG1024. These are in early pre-clinical testing. They are not thought to be ATP-competitive, although they are when used in EGFR as described in QSAR studies. These show some selectivity towards IGF-1R over IR. 2) Pyrrolo[2,3-d]-pyrimidine derivatives such as NVP-AEW541, which show far greater (100 fold) selectivity towards IFG-1R over IR."
