The drugs {currently|presently|at present|at the moment} {used|utilized|employed|utilised|applied|made use of} to treat leishmaniasis have limitations {concerning|regarding} {cost|price|expense}, efficacy and {safety|security}, {making|creating|producing|generating} urgent the {search for|look for} new therapeutic approaches. {Here|Right here} we report the antileishmanial activity of 14 gold(I) complexes. We {found|discovered|identified|located} that the complexes {were|had been|have been} active against L. infantum and L. braziliensis intracellular amastigotes with IC50 values ranging from 0.{5|five} to {5|five}.{5|five} μM. All complexes {were|had been|have been} potent inhibitors of trypanothione reductase (TR), with IC50 ranging from 1 to 7.{8|eight} μM. Triethylphosphine-derived complexes enhanced ROS production and decreased mitochondrial respiration {after|following|right after|soon after|immediately after|just after} {2|two} h exposure, indicating that gold(I) complexes {cause|trigger|result in|lead to|bring about} oxidative {stress|tension|anxiety|pressure|strain} by direct ROS production, by causing mitochondrial {damage|harm} or by impairing TR activity and {thus|therefore|hence|as a result} accumulating ROS. There was no cross-resistance to antimony; {in fact|actually|in reality|the truth is|in truth|in actual fact}, SbR (antimony-resistant mutants) strains {were|had been|have been} hypersensitive to {some of|a few of|a number of} the complexes. BALB/c mice infected with luciferase-expressing L. braziliensis or L. amazonensis and treated orally with 12.{5|five} mg/kg/day of AdT Et ({3|three}) or AdO Et ({4|four}) presented {reduced|decreased|lowered} lesion size and parasite burden, as revealed by bioimaging. {Combination|Mixture} of ({3|three}) and miltefosine {allowed|permitted} {for a|to get a|for any} 50 % reduction in miltefosine {treatment|therapy|remedy} time.
