Amphibian skin secretions are unique sources of bioactive molecules, particularly bioactive peptides. In this study, the skin secretion of the white-lipped tree frog (Litoria infrafrenata) was obtained to identify peptides with putative therapeutic potential. By utilizing skin secretion-derived mRNA, a cDNA library was constructed, a frenatin gene was cloned and its encoded peptides were deduce...

Scorpions are generally an important source of bioactive components, including toxins and other small peptides as attractive molecules for new drug development. Mesobuthus eupeus, from medically important and widely distributed Buthidae family, is the most abundant species in Iran. Researchers are interesting on the gland of this scorpion due to the complexity of its venom. Here, we have analyz...

A majority of terrestrial and marine organisms use to fend off a wide range of microorganisms, including bacteria and fungi by employing “antimicrobial peptides (AMPs)” that are ribosomally synthesized from proteinogenic amino acids. AMPs are a primary component of innate immune mechanisms in marine invertebrates. In contrast, marine sponges seem to contain no AMPs, but often contain nonribosom...

Insects or products derived from insects are considered as a valuable feed ingredient for aquaculture, poultry, and pigs but also exert possible secondary effects of health stimulators in livestock reported literature. Health benefits attributed to can create additional value the insect chain. Three categories bioactive compounds this desk study: antimicrobial peptides (such ?-helical peptides,...

• Undaria pinnatifida prepared like a soup has phlorotannins and small peptides. Bioactive molecules in U. can inhibit acetylcholinesterase. Aqueous extract inhibits the activity of HMGR, reducing cholesterol biosynthesis. Several changes are induced cell proteome with aqueous extract. is brown alga, largely used as food oriental countries. The purpose this work was to analyze several bioactivi...

Bioactive peptides derived from fish the byproduct protein hydrolysate have wide potential as functional food ingredients. The preparation of bioactive is commonly achieved via enzymatic hydrolysis; this most preferred method because it has high specificity, fewer residual organic solvents in product, and usually carried out mild conditions. use various enzymes such proteases widely practiced i...

In this work, peptides were extracted from Silver carp (SC) scales via protease hydrolysis and separated using two membranes (M1 M2). The results revealed that the water: SC scale ratios of 50.6 mL/g, alkaline 1 (AP1) dose 2313.6 U/mL, pH 8.14 optimal conditions, peptide yield reached 88.77 ± 0.32%. conditions separation clarified: operating pressure M1 (M2) was 0.25 (0.4) MPa, liquid temperatu...

Oral administration of food protein hydrolysate and naturally occurring peptides exert beneficial effects beyond conventional nutritional functions by supplying amino acids for synthesis. These are referred to as food-derived bioactive peptides. The coronavirus disease 2019 (COVID-19) is caused sever acute respiratory syndrome 2 (SARS-CoV-2) infection. Some host viral proteins involved in the e...
