PharmacoMicrobiomics: The Drug-Microbiome Portal

How Bugs Modulate Drugs?

Launched on 11/11/11; Current Release 1.3 (21 March 15)

Welcome To PharmacoMicrobiomics!

The PharmacoMicrobiomics web portal is a part of an initiative to explore the interactions between human-associated microbes (human microbiome) and drugs by building a knowledgebase that allows interested students and investigators "to predict the behavior of untested members of drug classes or unstudied microbial species, and to design laboratory experiments for testing these predictions. (More in BMC Bioinformatics 2011, 12(Suppl 7):A10)

What to Find Here?

You will be able to find different types of information mostly related to the effect of microbes on drugs (more specifically on the effect of human microbiota on drug disposition or pharmacokinetics). In the future, there may be more information about more complex drug-microbe interactions, and about microbes as drugs, drug factories, or drug-delivery vehicles.

You now can find several entries in the database, including:

You can also find more entries still in "draft" format (mostly Google Docs) that describe a long reading/task list for our current or future curators, and also for those community volunteers who are willing to join our efforts.

Random Interaction

chlorogenic acid (1794427)
unknown (0)
affect metabolic processing
Gut microbiota metabolize chlorogenic acid in to 3- hydroxy cinnamic acid and 3-(hydroxyl phenyl) propionic acid which are subject to phase II conjugation followed by excretion in urine. In absence of gut microbiota, chlorogenic acid is metabolized to benzoic acid which in turn is conjugated with glycine yielding hippuric acid. This has been verified by the absence of these metabolites upon administration of antibiotics and in germ free rats. Gonthier et al reported that the bioavailability of chlorogenic relies on its metabolism by gut microbiota. Variation in the concentrations of chlorogenic acid metabolites was found among rat population. H1NMR spectroscopy showed that elevated concentration of the metabolites in urine was accompanied by low hippuric acid concentration in a rat subpopulation that is similar in terms of species, genetic background and conditions of maintenance to the other group of rats (Gavaghan et al, 2001). This suggests the difference in gut microbiota between the two rats populations. Based on the results retrieved by Gonthier et al, the elevated concentration of the metabolites will result in turn in increased bioavailability and thereby augmented efficacy. (See record)
