Several experimental treatments have shown promise in animal models . These include inhibitors of oxidosqualene cyclase and squalene synthase , cysteine protease inhibitors , dermaseptins collected from frogs in the genus Phyllomedusa ( P. oreades and P. distincta ) , the sesquiterpene lactone dehydroleucodine ( DhL ) , which affect the growth of cultured epimastigote @-@ phase Trypanosoma cruzi , inhibitors of purine uptake , and inhibitors of enzymes involved in trypanothione metabolism . Hopefully , new drug targets may be revealed following the sequencing of the T. cruzi genome .
