Abstract	4-[18F]flouro-3-nitro-N-2-propyn-1-yl-benzamide ([18F]FNPB) was developed as a new stable aromatic prosthetic group for more efficient click labeling of peptides. A new aromatic precursor 3,4-dinitro-N-2-propyn-1-yl-benzamide was radiofluorinated using [18F]KF/K2.2.2 followed by HPLC purification to obtain the desired product [18F]FNPB. [18F]FNPB was synthesized with a 58% radiochemical yield, a specific activity?>?350?GBq/mu mol, and radiochemical purity was exceeded 98% in 40?min. The in vitro stability studies showed no detectable radiodefluorination over 2?h in mouse plasma. The click labeling yield of three different peptides with [18F]FNPB were all above 87%. The in vitro study suggests that [18F]FNPB may be stable?in vivo and could have general application in labeling peptides with high radiochemical yield for positron emission tomography applications.
