Arginine-rich Peptide Mixture, their Application Thereof in Cervical Cancer Therapy, and a Process for Producing same
20180009842 · 2018-01-11 ·

A process for producing an arginine-rich peptide mixture and the application thereof in cervical cancer therapy is provided. The process includes the following steps: A suspension of walnut meal and egg albumin is pretreated with ultrahigh pressure, and then digested by alkaline proteinase and papain in separated steps with the ultrasonic and microwave-assisted extraction. The peptides of interest are isolated from filtration supernatant obtained after the enzyme digestion by reversed phase high-performance liquid chromatography. By using the peptide mixture as a template, acrylic acid and methyl acrylic acid as functional monomers, triethylene glycol dimethacrylate as cross-linking agent, and isopropylthioxanthone in acetone as a photoinitiator, polymerization is induced by ultraviolet light to form a surface imprinted membrane for isolating and enriching the peptides of interest from the supernatant. The arginine content in the peptide mixture is more than 18%. The arginine-rich peptide mixture is able to strongly suppress the proliferation of human cervical cancer Hela cells. The approach is applicable to reduce the cost of production and speed up the commercialization of large-scale production.

Long-acting insulin analogues and derivatives thereof

The present invention relates to long-acting insulin analogues having an increased in vivo half-life in which the amino acid at position 22 of the B-chain of native insulin is substituted and one or more amino acids of the A-chain or B-chain of native insulin are additionally substituted, and to long-acting insulin analogue derivatives having a further increased in vivo half-life in which an albumin-binding domain is additionally fused to the long-acting insulin analogues. The insulin analogues or insulin analogue derivatives according to the present invention have a significantly increased in vivo half-life, and thus can provide convenience to diabetic patients who self-administer insulin by injection.

PURIFICATION METHOD FOR IMIDAZOLE DIPEPTIDES

The objective of the present invention is to provide a method of producing each high purity imidazole dipeptide in large quantities on an industrial scale, regardless of the type of animal extract employed. The objective is achieved by a method of producing a purified imidazole dipeptide composition, including the step (1) of subjecting an animal extract treatment solution containing at least two types of imidazole dipeptides to adsorption treatment carried out by bringing the solution into contact with a hydrophobic adsorption resin to adsorb the imidazole dipeptides onto the hydrophobic adsorption resin; and the step (2) of subjecting the hydrophobic adsorption resin adsorbing the imidazole dipeptides to elution treatment using an aqueous solution to mutually separate and collect the imidazole dipeptides to purify an imidazole dipeptide.
