description

The syntheses and first in vitro evaluations for two fluoride bearing sulfonylurea derivatives are reported. Firstly, the tolbutamide derivative 1-[4-(2-[18F]fluoroethoxy)benzenesulfonyl]-3-butyl urea (2-[18F]fluoroethyl-tolbutamide) could be labeled efficiently with [18F]fluoride. Subsequently, the glibenclamid derivative N-(2-(4-(N-((cyclohexylamino)carbonyl)sulfonylamino)phenyl)ethyl) 2-(5-chloro-2-[18F]fluorethoxy)phenyl) formamide (2-[18F]fluoroethyl-glibenclamide) was labeled with [18F]fluoride in high yields. Its ability to induce insuline secretion from rat beta-cells in relation to the original glibenclamide was determined.
