Background:

5-A-RU-PABC-Val-Cit-Fmoc is the prodrug of 5-A-RU[1]. 5-A-RU, a precursor of bacterial Riboflavin, is a mucosal-associated invariant T (MAIT) cells activator. 5-A-RU forms potent MAIT-activating antigens via non-enzymatic reactions with small molecules, such as glyoxal and methylglyoxal, which are derived from other metabolic pathways[2][3][4].

When added to MAIT cell cultures, 5-A-RU-PABC-Val-Cit-Fmoc (Compound 10) induces higher levels of mucosal-associated invariant T (MAIT) cell activation than 5-A-RU alone[1].
