Research Background
How the Human Gut Microbiota Influences Drug Metabolism
Characteristics of the Gut Microbiota: Composed of diverse microorganisms that vary significantly between individuals, capable of producing different metabolites.
Interactions Between Gut Microbiota and Drugs:
- Interacts with drugs, altering their effects.
- Metabolizes many drugs, with varying activity between individuals.
- Plays a role in drug inactivation, activation, detoxification, or re-toxification.
Therefore, the application of gut microbiota must consider diet, genetics, and personalized microbiota-based medical interventions. To predict these interventions, it is crucial to understand the distribution and stoichiometry of drug transformation reactions among different human microbial groups.

Discussion Questions
- AGORA2 covers 7,302 strains, yet the human gut contains even more microbial species. What are the key trade-offs between model coverage and model accuracy, and how would you decide which strains to prioritize for reconstruction?
- How would you design an experiment to validate the model’s predictions about drug metabolism by a specific gut microbe? What in vitro or in vivo approaches would be most appropriate?
