Microbiome Metabolite Mimics Accelerate Drug Discovery

A recent study by Dvořak et al. supports metabolite mimicry as a drug development strategy. A potent agonist of the human pregnane X receptor (hPXR) was designed from two ligands that are products of the microbial catabolism of tryptophan. Its validity was demonstrated in cellular assays and a murine colitis model expressing hPXR by a significant reduction in inflammation biomarkers.
