The design and synthesis of novel inhibitors of NADH:ubiquinone oxidoreductase
摘要:
Potent new inhibitors of NADH:ubiquinone oxidoreductase (complex 1) have been designed, with the help of molecular modelling, by hybridisation of known complex I inhibitors with inhibitors of cytochrome c oxidoreductase. The most interesting compound was the chromone 7 which was a selective inhibitor of complex I (IC50 15 nM) and showed acaricidal activity against spider mites. (C) 2003 Elsevier Ltd.

Synthesis and Biological Evaluation of the Mitochondrial Complex 1 Inhibitor 2-[4-(4-Fluorobutyl)benzylsulfanyl]-3-methylchromene-4-one as a Potential Cardiac Positron Emission Tomography Tracer
A series of fluorinated chromone analogs with IC50 values ranging from 9 to 133 nM for the mitochondrial complex I (MC-I) has been prepared. A structure -activity relationship (SAR) study of the most potent fluorinated chromone analog 10 demonstrated the linkage heteroatom preference of the side chain region of the molecule while maintaining potent MC-I inhibitory activity. Tissue distribution studies 30 min after [F-18]10 administration to Sprague-Dawley (SD) rats demonstrated high uptake of the radiotracer from the blood pool into the myocardium (2.24% ID/g), kidney (1.93% ID/g), and liver (2.00% ID/g). After 2 h about 66% of the activity in the myocardiurn at 30 min had been retained, whereas -70% had been cleared from the liver and kidney. MicroPET images of SD rats after [F-18]10 administration allowed easy assessment of the myocardium through 60 min with minimal lung or liver interference.
