Abrégé
The present invention relates to application of gossypol and its optical isomers to preparation of an anti-Coronavirus drug. Specifically disclosed is application of pharmaceutically acceptable salts, solvates, isotopes, stereoisomers, stereoisomer mixtures, and tautomers of the gossypol and its optical isomers to preparation of a drug for preventing and/or treating a disease caused by a Coronavirus. The Coronavirus is MERS-CoV, SARS-CoV, or SARS-CoV-2. It is found in the present invention for the first time that the gossypol and its optical isomers can inhibit the activity of Coronavirus 3CL proteases to achieve an anti-Coronavirus effect. The half maximal inhibitory concentrations of gossypol and (−)-gossypol to SARS-CoV proteases and SARS-CoV-2 3CL proteases are all lower than 10 μM. The anti-Coronavirus 3CL protease effect is good. Therefore, the gossypol and its optical isomers have the potential for use in the preparation of a drug for preventing and/or treating novel Coronavirus infections.

Polygoni Milletii Rhizome compositions and methods of preparing the same
A method of preparing a Polygoni Milletii Rhizome tincture includes: preparing a first mixture; extracting the first mixture with 70-90% ethanol under reflux condition to obtain a first extract solution; preparing a second mixture; extracting the second mixture with 50-70% ethanol to obtain a second extract solution; and mixing the first extract solution with the second extract solution to obtain the polygoni milletii rhizome tincture. A method of preparing a Polygoni Milletii Rhizome poultice includes: reparing a Polygoni Milletii Rhizome mixture; mixing the Polygoni Milletii Rhizome mixture and a skin penetration enhancer in water; mixing a moisturizing agent and a binder in water; adding a thickener in water; mixing methylparaben and ethylparaben in 90% ethanol; mixing all solutions to form a mixture; and applying the mixture on a non-woven fabric cloth and drying to form the Polygoni Milletii Rhizome poultice.
