Bioaccumulation of therapeutic drugs by human gut bacteria: duloxetine accumulation at different concentrations (L.saccharolytica;E.coli assays)


ABSTRACT:

Bacteria in the gut can modulate the availability and efficacy of therapeutic drugs. Interactions at this level have only recently started to being systematically mapped and the main underlying mechanism proposed is chemical transformation of drugs by microbes (biotransformation). Here, we investigated the depletion of 15 structurally diverse drugs by 25 representative gut bacterial strains. This revealed 70 bacteria-drug interactions, 29 of which had not been reported before.

Over half of the new interactions can be ascribed to bioaccumulation, that is bacteria storing the drug without chemically modifying it, and in most cases without their growth being affected. As a case in point, we studied the molecular basis of bioaccumulation of the widely used antidepressant duloxetine by using click-chemistry, thermal proteome profiling and metabolomics. We find that duloxetine binds to several metabolic enzymes and changes metabolite secretion of the respective bacteria. When tested in a defined microbial community of accumulators and non-accumulators, duloxetine markedly altered the community composition through metabolic cross-feeding. We further validated our findings in an animal model, showing that bioaccumulating bacteria attenuate the behavioral response of Caenorhabditis elegans to duloxetine.

Taken together, bioaccumulation by gut bacteria might be a common mechanism that alters drug availability and bacterial metabolism, with implications for microbiota composition, pharmacokinetics, side effects and drug responses, likely in an individual manner.
