Abstract: Provided are an improved cell-permeable (iCP)-SOCS3 recombinant protein and uses thereof. Suppressor of cytokine signaling-3 (SOCS3) is an endogenous protein inhibitor of JAK/STAT pathway, and an aberrant expression of SOCS3 protein was observed in human solid tumors including gastric, colorectal and breast cancer, and glioblastoma. The iCP-SOCS3 recombinant protein provided herein may be used as protein-based anti-lung cancer agent by utilizing the platform technology for macromolecule intracellular transduction.

Abstract: The present invention provides a modified atrial natriuretic peptide that exhibits prolonged duration in blood and maintains cGMP elevating activity. The present invention provides a modified peptide in which at least one sugar substance is linked directly through a glycosidic bond or via a linker structure to at least one hANP peptide, or a pharmaceutically acceptable salt thereof, a medicament comprising the modified peptide or the salt thereof as an active ingredient, etc.
Abstract: The present invention relates to the fields of chemistry, pharmacy, biotechnology and medicine. More particularly, the present invention describes: the use of a peptide compound for preparing an anticonvulsant pharmaceutical composition; and a therapeutic method. The peptide compound of the claimed pharmaceutical composition binds to and/or modulates the activity of cannabinoid receptors (CB), particularly CB1 and/or CB2, and has proven to be extremely useful as an anticonvulsant. In one embodiment, the claimed pharmaceutical composition provides excellent anticonvulsant results when administered orally to a mammal, and, in addition to other advantages and technical effects, does not entail the drawbacks arising from the use of cannabinoid substances such as cannabidiol, and provides a stronger therapeutic effect in smaller dosages and with fewer side effects.

Abstract: Provided are methods for linking polypeptides (including peptides and proteins) to other moieties using radical imitated thiol-ene chemistries, for example, modifying a polypeptide by introducing reactive thiol groups and reacting the thiol groups with olefin-containing reagents or alkyne-containing reagents under conditions that support radical thiol-ene or thiol-yne reactions. The reactive thiol groups have greater activity for radical thiol-ene reactions that a cysteine thiol group, including thiol groups that are separated from the peptide backbone by at least two carbon atoms, for example, the thiol group of a homocysteine residue. Also provided are compositions and biomaterials containing the linked polypeptides, for example, peptide and protein conjugates, and thiol-ene based biocompatible hydrogel polymers, and their uses in the medical field.
