Abstract

(Z)-2-((1H-Indazol-3-yl)methylene)-6-methoxy-7-(piperazin-1-ylmethyl) benzofuran-3(2H)-one is a potent and selective proviral integration site in moloney murine leukemia virus kinase 1 (PIM1) inhibitor with an IC50 value of 3 nM. (Z)-2-((1H-Indazol-3-yl)methylene)-6-[11C]methoxy-7- (piperazin-1-ylmethyl)benzofuran-3(2H)-one, a new potential PET probe for imaging of the enzyme PIM1, was first designed and synthesized in 20-30% decay corrected radiochemical yield and 370-740 GBq/μmol specific activity at end of bombardment (EOB). The synthetic strategy was to prepare a carbon-11-labeled Boc-protected intermediate followed by a quick acidic de-protection.
