[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.

A newly developed C–S bond formation nucleophilic aromaticsubstitution (SNAr) reaction in aqueous Triton X-100 (TX100) micelles has been disclosed. This chemistry, in which odorless, cheap and stable thiourea in place of thiols is used as the sulfur reagent, provides an efficient approach for the generation of nitroarylthioethers, which are useful structural units of many bioactive molecules, rendering
hitherto unknown isomeric fluoronitrobenzenesulfonyl chlorides is described. The compounds are prepared from difluoronitrobenzenes by a two-step procedure. In the first step the starting compounds undergo a regioselective reaction with phenylmethanethiol giving rise to the corresponding thioethers. The oxidative cleavage of the latter with chlorine results in the sulfonyl chlorides in good yields. One
