Reduction of Folate by Ti3+

Abstract
Both folate and 7,8-dihydrofolate can be reduced by TiCl3, but the reduction of dihydrofolate requires a temperature above 30°. The reaction of folate with Ti3+ proceeds with rapid formation of a complex between the metal and the pterin coenzyme, with a stoichiometry of 2 Ti: 1 folate. Kinetic experiments have shown that the reduction of folate takes place as a slower reaction, after the formation of the intermediate complex. A possible structure of the intermediate and mechanism for the reduction reactions is presented.
