Abstract: The present invention relates to a method for preventing or treating a coronavirus infectious disease, comprising administering to a patient in need thereof a therapeutically or prophylactically effective amount of a compound represented by formula (I) or pharmaceutically acceptable salts thereof. The compound represented by formula (I) is used for treating patients with novel coronavirus pneumonia, and shows obvious advantages in all of the clearance rate by viral nucleic acid test, the course of clearance, and the cure and discharge time.

Abstract: This application relates generally to certain substituted pyrrolizine compounds, and pharmaceutical compositions which inhibit HBV replication, and methods of making and using them.

Abstract: The present invention discloses a crystal form, a preparation method and an application of a 4?-substituted nucleoside compound I having the following structure, including salts, prodrugs, and compositions thereof. Animal pharmacokinetic studies demonstrated that the effective drug concentrations of Compound Ia and Compound Ig in HIV target cells, peripheral blood mononuclear cells (PBMC), were effective in inhibiting HIV replication after 7 and 5 days, respectively. Therefore, Compound I can be used as a long-acting drug for preventing and treating AIDS. R is selected from ethynyl, azide, and cyano groups, X is selected from hydrogen and fluorine, and B is selected from B1 and B2.
