Model investigations for vanadium–protein interactions: first vanadium(III) complexes with dipeptides and their oxovanadium(IV) analogues

Abstract

Reaction of the dipeptides H₂Gly-Tyr and H₂Gly-Phe with VCl₃ and 1,10-phenanthroline affords the compounds [V(Gly-Tyr)(phen)]Cl·3MeOH 1 and [V(Gly-Phe)(phen)]Cl·3MeOH 2; aerial oxidation of the complexes 1 and 2 gives their oxovanadium(IV) analogues [VO(Gly-Tyr)(phen)] 3 and [VO(Gly-Phe(phen)] 4, respectively; the X-ray crystal structure of 3 is reported.
