A team of researchers has identified glycyrrhizin, a compound derived from black licorice, as a potential treatment for inflammatory bowel disease using a novel stem cell-based intestinal model.
The scientists developed a system using human stem cells to recreate intestinal tissue in the laboratory. This approach allowed them to screen thousands of chemical compounds systematically to identify candidates that could reduce inflammation in the gut. Glycyrrhizin emerged from this screen as the most promising compound.
The researchers tested glycyrrhizin in two experimental systems. In lab-grown human intestinal tissue, the compound reduced inflammation and cell death associated with IBD. When tested in mice with IBD-like conditions, glycyrrhizin similarly decreased intestinal damage. The results suggest the compound works by suppressing inflammatory responses in the gut.
Glycyrrhizin occurs naturally in licorice root and has been used in traditional medicine for centuries. The compound's discovery in this IBD context comes from systematic screening rather than folklore-based exploration, lending scientific weight to the finding.
The stem cell-derived intestinal model represents a shift in drug discovery methodology. Rather than relying solely on animal models or clinical trials, researchers can now test compounds on human tissue grown in controlled laboratory settings. This approach potentially accelerates the identification of new treatments while reducing reliance on animal testing.
IBD affects millions worldwide and currently lacks a cure. Existing treatments focus on managing symptoms and suppressing immune responses, but many patients develop resistance or experience side effects. A new compound targeting inflammation could offer an alternative therapeutic pathway.
The next steps involve determining glycyrrhizin's mechanism of action at the molecular level and assessing whether the compound can safely reach the intestine in sufficient concentrations when taken orally. Clinical trials would follow if preclinical data support further development. The researchers note that while black licorice contains glycyrrhizin naturally
