Abstract
The invention relates to odorrana tiannanensis natural antioxidant peptide reconstructed bodies and a preparation method and application thereof. The reconstructed bodies comprise two types, i.e. OA-OTVC and OA-OTC, which are linear chain small peptides and respectively contain sixteen amino acid residues and fourteen amino acid residues, the molecular weight of the OA-OTVC and the molecular of the OA-OTC are respectively 1688.06Da and 1489.79Da, and the isoelectric points are respectively 9.85 and 9.62. The polypeptide complete sequence primary structure of the OA-OTVC is valine - valine- lysine - cysteine - serine - cysteine - arginine - proline - glycine - serine - proline - alanine - proline - arginine - cysteine - lysine; the polypeptide complete sequence primary structure of the OA-OTC is lysine - cysteine - serine - cysteine - arginine - proline - glycine - serine - proline - alanine - proline - arginine - cysteine - lysine. The reconstructed bodies have the advantages of good antioxidant activity, small molecular weight and simple structure, and can be used for preparing antioxidant drugs, food additives, cosmetics and the like.
Description
Technical field
The invention provides two kinds and derive from transformation body OA-OTVC, OA-OTC of the Natural Antioxidant Peptides of the smelly frog in the southern regions of the Yunnan Province (Odorrana tiannanensis) and preparation method thereof, application, belong to field of biomedicine technology.
Background technology
Free radical refers to any atom that comprises a unpaired electron or atomic group.Organism is mainly active oxygen radical with the free radical that the external world contacts and self produces, and comprises ultra-oxygen anion free radical, hydroxy radical qiao, hydrogen peroxide, lipid peroxy free radical, nitrogen peroxide, nitric oxide free radical, singlet oxygen and ozone.Under higher concentration, cellularstructure, nucleic acid, lipid and the protein of active oxygen radical to biomass cells causes damage.Cause DNA damage, further cause misreplication, genomic instability, transcribe unexpected initial or termination, thereby cause organism variation or disease to occur; Cause cell membrane fluidity and permeability changes, cause cellularstructure and changing function; Cause protein oxidation, cause protein denaturation and inactivation.
Find at present, active oxygen radical is relevant with multiple human diseases, as cancer, cardiovascular and cerebrovascular diseases, ischemical reperfusion injury, rheumatoid arthritis, diabetes, alzheimer's disease, Parkinson's disease and aging etc.In order to resist the infringement of active oxygen radical to body, in very long evolutionary process, organism forms multiple different free radical scavenging system, comprise the small-molecule substance of non-genomic coding, as uric acid, vitamins C, vitamin-E, carotenes, Thioctic Acid and ubiquinone etc.; The macromole antioxidant reductase of genes encoding, as superoxide-dismutase (SOD), catalase, peroxidase, Trx enzyme system and gsh enzyme system; The small molecules anti-oxidation peptide class of genes encoding, as the various small molecules antioxidation polypeptides of finding from batrachians ranid skin.Various dissimilar free-radical scavengerss have great application potential at medicine and cosmetic field, as vitamins C, superoxide-dismutase (SOD) and small molecules antioxidation polypeptide.
China has abundant amphibian animal resource, and it is the important component part of Chinese biological resource, and wherein a lot of species have the value such as edible or medicinal, have very large exploitation potentiality.Amphibians is owing to living in for a long time under the environment that humidity, darkness, microorganism grow in a large number, three cover defense mechanisms in long-term natural evolution process, are formed: (1) physical barriers, mucous gland is secreted a large amount of glycoprotein and proteoglycan, be wrapped in skin appearance face, hinder the intrusion of pathogenic bacteria; (2) acquired immune system, contains IgG antibody in Amphibians skin; (3) innate immune system, is mainly made up of a large amount of antibacterial peptides and anti-oxidation peptide.There is long history in China to the application of batrachians medicine, but the research of its activeconstituents and pharmacological properties is mainly concentrated on to the organic molecules such as alkaloid, and the research of its skin activity peptide matters is also rarely had to report.The smelly frog in the southern regions of the Yunnan Province (Odorrana tiannanensis) belongs to amphibia Anura Ranidae Rana, is Chinese endemic species, is distributed in the ground such as Hainan, Yunnan, moves in the dark mountain stream that The turbulent river crashes its way through more.The type locality of these species is at Hekou, Yunnan Province.Have been reported about the smelly frog form in the southern regions of the Yunnan Province, growth and molecular evolution at present, about the natural antibacterial-anti-oxidant multifunctional polypeptide in smelly frog source, the southern regions of the Yunnan Province, we have been reported in previous work.
Transformation body OA-OTVC, the OA-OTC of the Natural Antioxidant Peptides of the smelly frog in the southern regions of the Yunnan Province of the present invention (Odorrana tiannanensis), molecular weight is little, simple in structure, is linear molecule, facilitates chemosynthesis and preparation.Compare other anti-oxidation peptides of having reported and transformation precursor, the oxidation-resistance of OA-OTVC, OA-OTC is stronger, to DPPH, ABS free radical all has extremely strong reductibility, therefore can become the good template of exploitation anti-oxidation medicine, foodstuff additive, makeup effective constituent.
