Purohit, Ajay published the artcileSynthesis and Biological Evaluation of Pyridazinone Analogues as Potential Cardiac Positron Emission Tomography Tracers, Category: alcohols-buliding-blocks, the main research area is fluorinated pyridazinone preparation cardiac positron emission tomog tracer SAR; mitochondrial complex 1 inhibitor fluorinated pyridazinone preparation SAR; imaging PET tracer fluorinated pyridazinone preparation structure activity relationship.
A series of fluorinated pyridazinone derivatives, e.g. I [R1 = H, R2 = CH2(CH2)2CH2F, O(CH2)2CH2F, CH2CH2CHFCH3, etc.; R1 = D, R2 = CH2OCD2CD2F], with IC50 values ranging from 8 to 4000 nM for the mitochondrial complex 1 (MC1) have been prepared Structure-activity relationship (SAR) assessment indicated preference of the fluorine label to be incorporated on an alkyl side chain rather than directly on the pyridazinone moiety. Tissue distribution studies of a series of analogs ([18F]I) in Sprague-Dawley (SD) rats identified I (R1= H, R2 = CH2OCH2CH218F) (II) as the most promising radiotracer with high uptake in cardiac tissue (3.41%ID/g; 30 min post injection) in addition to favorable heart to nontarget organ distribution ratios. MicroPET images of SD rats and nonhuman primates after II administration allowed easy assessment of the myocardium through 60 min with minimal lung or liver interference.
