Abstract: A polypeptide-coupled small molecule compound and its antiviral applications are provided. The polypeptide-coupled small molecule compound is obtained by linking a polypeptide with a sequence X?nLXGG and a small molecule compound capable of inhibiting activity of papain-like protease (PLpro) of coronavirus through a chemical bond. The polypeptide with the sequence X?nLXGG is a polypeptide with a sequence LXGG at its carboxyl terminal, X and X? are independently any amino acid, and n is an integer between 1-50. The structure of the small molecule compound capable of inhibiting the activity of PLpro contains an amino group or a hydroxyl group. The polypeptide-coupled small molecule compound can inhibit the PLpro of SARS-CoV-2 in a targeted manner, thereby inhibiting the polyprotein cleavage of coronavirus in the host, and achieving the purpose of inhibiting the replication of coronavirus in the host. It has the advantages of synergistic inhibition, low cytotoxicity and favorable solubility.

Abstract: Provided are a method for predicting a risk of deterioration of a pathogenic condition of a patient suffering a coronavirus disease (COVID-19), especially a severe patient suffering a COVID-19 and a kit thereof. The method of the present application may effectively predict the deterioration of the pathogenic condition of the patient suffering a COVID-19, thereby carrying out clinical intervention in advance, to improve prognosis of the patient suffering a COVID-19. The present application finds for the first time that the level of a heparin-binding protein (HBP) can be used as a significant indicator for early predicting relapse of the patient suffering a COVID-19, expression time of an HBP indicator is around 5 days earlier than that of a series of other clinical indicators, and thus the HBP indicator particularly has a clinical value.

Abstract: The present invention relates to a new application of Fructus schisandrae total polysaccharides in preparation of medicine or nutraceuticals for treating coughing, and more specifically to a new application of Fructus schisandrae total polysaccharides in preparation of medicine or nutraceuticals for preventing and relieving coughing and eliminating airway inflammation. Experiments demonstrate that the Fructus schisandrae total polysaccharides can remarkably reduce the coughing times of a guinea pig with increased cough sensitivity induced by cigarette smoke and an acute cough guinea pig induced by citric acid smoke, prolong the latent period of cough, and significantly reduce the airway inflammation of the guinea pig with increased cough susceptibility induced by cigarette smoke, so that the Fructus schisandrae total polysaccharides can be used for preparing drugs for preventing cough, relieving cough and eliminating airway inflammation.
