In recent years, evidence for the anti-cancer activity of lichen secondary metabolites has been rapidly increasing. In this study, we synthesised analogues of diffractaic acid, a lichen secondary metabolite, and evaluated their ability to suppress colorectal cancer stem potential. Among the 10 compounds after H/CH₃/benzylation of the diffractaic acid structure or modifications in an aromatic hydrophobic domain, TU3 has a more inhibition effect on the stem potential of colorectal cancer compared to other compounds.

However, the mechanism underlying the anticancer effect of UA remains to be clarified. In this study, the target protein of UA was identified using a UA-linker-Affi-Gel molecule, which showed that UA binds to the 14-3-3 protein.

To screen for novel lichen secondary metabolites that inhibit the stemness potential of colorectal cancer cells, we tested acetone extracts of 11 lichen samples collected in Chile. Tumidulin, isolated from sp.
