Several quinazoline derivatives were made as mitochondrial complex I inhibitors. Compound 4 showed an IC50 Of 11.3 nM and was the most potent compound of this series. The F-18 analog of 4, [18F] 4, was injected in the rat and showed high and rapid heart uptake, fast liver clearance, and low blood uptake. Images obtained using a mu PET showed clear delineation of the myocardium in normal rats and perfusion deficit in ischemic rats. In the non-human primate, [18F] 4 showed rapid uptake and clearance from the myocardium and high liver uptake. (C) 2007 Elsevier Ltd. All rights reserved.
