Effect of whey protein-derived decapeptide on mood status and blood variables in healthy adults: a randomized, double-blind, placebo-controlled cross-over trial.

Purpose: The importance of maintaining good mental health with overall well-being has recently drawn attention from various fields. Functional peptides found from various protein sources reportedly reduce mental health problems. We found a new decapeptide (AJI-801) from whey proteins, which can possibly improve mood status and increase blood acetyl-L-carnitine (ALC) and fibroblast growth factor 21 (FGF21) levels.

One-step construction of ferritin encapsulation drugs for cancer chemotherapy.

Conventionally, a disassembly and reassembly method has been used for encapsulation of drug molecules in ferritin protein nano-cages. However, clinical applications of ferritin have been greatly restricted by its limited drug-loading capacity and process complexity. Here, we establish a simple high yield process for preparing high drug-loaded ferritin nanomedicine for industrial production.

Facile and Efficient Chemoenzymatic Semisynthesis of Fc-Fusion Compounds for Half-Life Extension of Pharmaceutical Components.

The formation of Fc-fusions, in which biologically active molecules and the Fc fragment of antibodies are linked to each other, is one of the most efficient and successful half-life extension technologies to be developed and applied to peptide and protein pharmaceuticals thus far. Fc-fusion compounds are generally produced by recombinant methods. However, these cannot be applied to artificial middle molecules, such as peptides with non-natural amino acids, unnatural cyclic peptides, or pharmaceutical oligonucleotides.

AJS1669, a novel small-molecule muscle glycogen synthase activator, improves glucose metabolism and reduces body fat mass in mice.

Impaired glycogen synthesis and turnover are common in insulin resistance and type 2 diabetes. As glycogen synthase (GS) is a key enzyme involved in the synthetic process, it presents a promising therapeutic target for the treatment of type 2 diabetes. In the present study, we identified a novel, potent and orally available GS activator AJS1669 {sodium 2-[[5-[[4-(4,5-difluoro-2-methylsulfanyl-phenyl)phenoxy] methyl]furan-2-carbonyl]-(2-furylmethyl)amino] acetate}.
