In order to explore a new type of anti-diabetic molecules, dipeptide derivatives containing uracil structural units were designed. The key intermediate S-thymine-L-cysteine (IM-2) was obtained from uracil, paraformaldehyde and cysteine through two step reactions, and then 16 dipeptide derivatives were successfully synthesized through amino protection, carboxylation and amino acid coupling. All new compounds have been characterized by 1H NMR, 13C NMR and HRMS, and the peroxisome proliferator response element (PPRE) activated activity, α-glucosidase-rat inhibitory activity and dipeptidyl peptidase-4 (DPP-4) inhibitory activity were screened for all target molecules. The results showed that these molecules had weak above-mentioned activities, meanwhile the change trend of α-glucosidase-rat inhibitory activity of these molecules is opposite to that of PPRE agonistic activity and DPP-4 inhibitory activity. It maybe provides an idea for the research of designing novel polypeptide multi-target drugs.

Key words: diabetes, uracil, dipeptide derivative, peroxisome proliferator response element (PPRE), α-glucosidase-rat inhibitory activity, dipeptidyl peptidase-4 inhibitory activity
