In all the living systems, reactive oxygen species (ROS) metabolism provides resistance against internal and external oxidative stresses. Auranofin (AF), an FDA-approved gold [Au(I)]-conjugated drug, is known to selectively target thiol-reductases, key enzymes involved in ROS metabolism. AF has been successfully tested for its inhibitory activity through biochemical studies, both in vitro and in vivo, against a diverse range of pathogens including protozoa, nematodes, bacteria, and so forth. Cocrystal structures of thiol-reductases complexed with AF revealed that Au(I) was coordinately linked to catalytic cysteines, but the mechanism of transfer of Au(I) from AF to catalytic cysteines still remains unknown. In this study, we have employed computational approaches to understand the interaction of AF with thiol-reductases of selected human pathogens. A similar network of interactions of AF was observed in all the studied enzymes. Also, we have shown that tailor-made analogues of AF can be designed against selective thiol-reductases for targeted inhibition. Molecular dynamics studies show that the AF-intermediates, tetraacetylthioglucose (TAG)-gold, and triethylphosphine (TP)-gold, coordinately linked to one of catalytic cysteines, remain stable in the binding pocket of thiol-reductases for and (PfTrxR). This suggests that the TP and TAG moieties of AF may be sequentially eliminated during the transfer of Au(I) to catalytic cysteines of the receptor.
