4-Iodo-L-phenylalanine may be used in protein engineering as a model unnatural α amino acid to alter primary amino acid composition via the opal (UGA) codon.
The Pd-catalyzed Sonogashira coupling of ferrocene alkyne derivatives as metal probes to iodophenylalanine containing peptides is described. 4-Iodophenylalanine was incorporated into dipeptides and the neuropeptide [Leu5]-enkephalin (Enk) by solid phase peptide synthesis, thereby creating a functional group suitable for the

A variety of unique codons have been employed to expand the genetic code. The use of the opal (UGA) codon is promising, but insufficient information is available about the UGA suppression approach, which facilitates the incorporation of non-natural amino acids

An Escherichia coli suppressor tRNA(Phe) (tRNA(Phe) (CUA)) was misacylated with 4-iodo-L-phenylalanine by using the A294G phenylalanyl-tRNA synthetase mutant (G294-PheRS) from E. coli at a high magnesium-ion concentration. The preacylated tRNA was added to an E. coli cell-free system and a

This work describes the synthesis and the tumor affinity testing of no-carrier-added (n.c.a.) p-[(124)I]iodo-L-phenyalanine ([(124)I]IPA) and n.c.a. p-[(131)I]iodo-l-phenyalanine ([(131)I]IPA) as radiopharmaceuticals for imaging brain tumors with PET and for radionuclid-based therapy, respectively. Parameters for labeling were optimized with regard to

p-[123I]iodo-L-phenylalanine (IPA) is a recently described radiopharmaceutical which is highly accumulated in gliomas. The present investigation was designed to evaluate the feasibility of single photon emission tomography (SPET) with IPA to image brain tumours under routine clinical conditions. Using a
