By using in silico molecular docking, we predicted a high potential of mangiferin to inhibit transthyretin amyloidogenesis. Subsequently, we tested this prediction in an in vitro system. The study involved testing effect of mangiferrin in a system that included isolated and purified recombinant transthyretin under fibrillogenesis conditions and a detection assay based on the fluorescent dye thioflavin T, characteristic of amyloid fibrils. The conditions for fibrillogenesis of this protein at neutral pH values were established. Using the developed test system, it was shown that mangiferin is able to inhibit abnormal transthyretin fibrillogenesis.
