[11C]GSK2126458 and [18F]GSK2126458, the first radiosynthesis of new potential PET agents for imaging of PI3K and mTOR in cancers
摘要:
GSK2126458 is a highly potent inhibitor of phosphoinositide 3-kinase (PI3K) and mammalian target of rapamycin (mTOR) with low picomolar to subnanomolar activity. [C-11]GSK2126458 and [F-18]GSK212 6458, new potential PET agents for imaging of PI3K and mTOR in cancer, were first designed and synthesized in 40-50% and 20-30% decay corrected radiochemical yield, and 370-740 and 37-222 GBq/lmol specific activity at end of bombardment (EOB), respectively.

Condensations of o-halo-substituted benzenesulfonylchlorides with 3-aminoazoles give the corresponding azolo[c][1,2,4]benzothiadiazine S,S-dioxides. o-Fluorobenzenesulfonyl chlorides and o-bromobenzenesulfonyl chlorides bearing a nitro group are reactive enough to give the desired azolo[c][1,2,4]benzothiadiazine S,S-dioxides in a one-pot, base-promoted reaction. In all other cases, open-chain sulfonylated
