Abstract
In this study, the effect of Douchi extract (DWE) on α-glucosidase and angiotensin-converting enzymes (ACE) were investigated, and several novel peptides with inhibitory activity against α-glucosidase and ACE were identified using peptidomics approach based on UPLC-MS/MS. The average inhibition rates of DWE on α-glucosidase and ACE were 73.75-78.10% and 4.56-27.07%, respectively. In the DWE, a total of 710 peptides were detected. Two novel peptides with potential inhibitory activity against α-glucosidase were identified using the correlation analysis, database alignment and molecular docking methods. They were DVFRAIPSEVL and DRPSINGLAGAN, with the IC50 values of 0.121 and 0.128 mg/mL, respectively. Also, four novel peptides with potential inhibitory activity against ACE were identified: PSSPFTDLWD, EEQDERQFPF, PVPVPVQQAFPF and PSSPFTDL, with IC50 values of 1.388, 0.041, 0.761 and 0.097 mg/mL, respectively. These results indicated that combining peptidomics and molecular docking is an effective alternative strategy for rapidly screening numbers of novel bioactive peptides from foods.

Abstract
The use of natural antimicrobial peptides (AMPs) is limited. Modifications of peptides by in silico predictions and computational methods can lead to more accurate designs and reducing their high synthesis costs, instability, and cytotoxicity. In this study, the antifungal properties of CecropinA-Magenin2 (CE-MA) hybrid peptide and its truncated derivatives were evaluated. Eleven C-terminal-truncated derivatives were designed and three of them with 10, 8 and 6 residues namely CMt1, CMt2 and CMt3 were selected through an initial screening based on the prediction of antimicrobial and antifungal activities, toxicity and physicochemical properties. These derivatives and the parental CE-MA peptide were synthesized. Then, based on molecular docking studies, antimicrobial tests and cytotoxicity assays, CMt1 peptide was selected for further studies such as time of killing, combinatorial effects with other drugs and the mechanism of action. The results showed that CE-MA is a weak antifungal peptide but its truncated derivative, CMt1 showed a strong antifungal activity with less toxicity. The results of the ergosterol assay, confocal microscopy and FE-SEM studies indicated that invasion to cell wall and membrane components were the main antifungal mechanisms of CMt1 peptide. Altogether, here we introduce a new truncated peptide with a strong antifungal activity with less toxicity which can be a good candidate for further in vivo and clinical studies to be used as an antifungal drug.
