- Abstract
Inhibition of biosynthetic pathways of compounds essential for Trypanosoma cruzi is considered as one of the possible action mechanisms of drugs against Chagas disease. Here, we investigated the inhibition of galactonolactone oxidase from T. cruzi (TcGAL), which catalyzes the final step in the synthesis of vitamin C, an antioxidant that T. cruzi is unable to assimilate from outside and must synthesize itself, and identified allylbenzenes from plant sources as a new class of TcGAL inhibitors. Natural APABs (apiol, dillapiol, etc.) inhibited TcGAL with IC50 = 20-130 µM. The non-competitive mechanism of TcGAL inhibition by apiol was established. Conjugation of APABs with triphenylphosphonium, which ensures selective delivery of biologically active substances to the mitochondria, increased the efficiency and/or the maximum percentage of TcGAL inhibition compared to nonmodified APABs.
