Background: Type 2 diabetes mellitus (T2DM), which is the epidemic of the 21st century, has affected millions of people worldwide. Traditional methods available for the treatment are associated with various side effects. Among the newer therapies, DPP-4 (Dipeptidyl peptidase-4) inhibition has been a promising therapy for the past decade with the scope of further development, especially in peptidomimetics. Objective: 5(S)-methyl-L-proline containing peptidomimetic compounds were designed in the previous work. The designed compounds were synthesized and characterized by spectral methods, such as mass spectrometry, 1H NMR, and 13C NMR (Nuclear magnetic resonance) spectroscopy. The purity of the final compounds was determined by high-performance liquid chromatography (HPLC). The synthesized compounds were in vitro evaluated for their DPP-4 inhibitory activity. Method: Compounds were peptide in nature and were synthesized using the conventional synthesis approach, where peptide synthesis was done using an acid-amine coupling reagent. They were evaluated through fluorimetric enzyme-based assay using a DPP-4 inhibitor screening kit. Moreover, the CLARIOstar microplate reader instrument was used to measure fluorescence. Results: 5(S)-methyl-L-proline containing 13 compounds were synthesized. All of them were characterized for structural integrity using spectral methods. They had HPLC purity of more than 95% and were evaluated for DPP-4 inhibition. Compounds 001, 007, 010, 011, 014, and 017 were found to have good inhibition than others. These compounds were further evaluated at different concentrations to develop a linear correlation coefficient (R2). Conclusion: Six compounds were found to have good DPP-4 inhibition, hence it further opens the possibility of developing DPP-4 inhibitor-containing 5(S)-methyl-L-proline.

Nowadays kinin is the most effective antimalarial drug and its used as an alternative in malaria treatment. However, toxicity of quinine restrict its use as an antimalarial drug. Lipophilicity and long half-life (t½) of quinine that reach 10-20 hours are responsible for its toxicity. The aim of this research is to obtain more polar quinine derivatives by means of hydrogen peroxide reactions to reduce the toxicity. The reactions using hydrogen peroxyde is performed analogously to the procedures reported in the literature. Extract of pure anhydrous kinin is purified in coloumn chromatography followed by structure elucidation. Synthetic product is tested in vitro against Plasmodium falciparum. The characterization of reaction products is performed with proton (1H) and carbon 13 (13C) nuclear magnetic resonance (NMR) spectroscopy. It showed that the reaction using reagents led to epoxidation of vinyl substituents of chinuclidine ring with 61,08% yields. Antimalarial test against Plasmodium falciparum obtained 1.250-2.500 μg/mL of IC50 value. The IC50 values indicated that the synthesis products were not potential for malaria treatment.
