Abstract: Provided are a GLP-1(7-37) polypeptide analogue, a fatty acid-modified derivative of the analogue, and a medicament comprising the derivative. Further, also provided are a preparation method of the derivative, and use of the same in the preparation of a medicament.

Abstract: Provided are an interleukin 29 (IL29) mutant protein, and a fusion protein, a conjugate, a pharmaceutical composition, a product and a kit which comprises the mutant protein. The provided IL29 mutant protein has good activity and stability, and can effectively prevent and/or treat viral infectious diseases, tumors and other diseases needing to regulate the body immune function.

Abstract: Disclosed in the present application is a crystal polymorph of potassium N-[8-(2-hydroxybenzoyl)amino]octanoate, wherein the crystal polymorph of potassium N-[8-(2-hydroxybenzoyl)amino]octanoate is crystal Form I, and the crystal Form I has at least an X-ray powder diffraction pattern with characteristic peaks represented by 2?° of 7.83±0.2, 26.64±0.2 and 18.89±0.2. The crystal polymorph of potassium N-[8-(2-hydroxybenzoyl)amino]octanoate provided by the present application has four crystal forms, has high solubility and strong stability, can deliver drugs more effectively, increases the permeability of the delivered drugs in the gastrointestinal tract, and is beneficial to the preparation of oral preparations, such that preventive and/or therapeutic drugs can be better delivered into the body to achieve the effect of improving the bioavailability.

Abstract: Provided are a GLP-1(7-37) polypeptide analogue, a fatty acid-modified derivative of the analogue, and a medicament comprising the derivative. Further, also provided are a preparation method of the derivative, and use of the same in the preparation of a medicament.
