Abstract: The present invention relates to a heterocyclic compound, a pharmaceutical composition comprising same, and a preparation method for the heterocyclic compound, and further relates to a use of the compound in the preparation of a drug for treating thromboembolic diseases.

Abstract: The invention relates to a polyamide compound and a use thereof. Specifically, the invention relates to a type of polyamide compound (which preferably comprise one or more amide bonds formed by condensation of same or different L-amino acids or D-amino acids), or stereoisomers, crystalline polymorphs, solvates, metabolites, prodrugs or pharmaceutically acceptable salts or esters thereof, or pharmaceutical compositions thereof, as well as a method for preparing the polyamide compound and a use thereof in the prevention or treatment of diseases associated with ?-opioid receptor. The polyamide compound of the invention has excellent ?-opioid receptor agonistic activity and hydrophilicity, thus having a lesser ability of penetrating the blood-brain barrier and a lower capacity for entering the brain.

Abstract: The present invention relates to an azetidine derivative for use as a Janus kinase (JAK) inhibitor, a drug composition comprising same, a preparation method therefor, and a use thereof in the treatment of JAK-related diseases comprising, for example, inflammatory diseases, autoimmune diseases, and cancers.

Abstract: The present application relates to a method for the prevention or treatment of an abnormal cell proliferative disease in a mammal, wherein the method comprises administering to the mammal an effective amount of a 4?-thionucleoside compound or a pharmaceutically acceptable salt, ester, hydrate, solvate thereof, or racemate thereof, or a mixture thereof.

Abstract: The present invention relates to a novel compound of 4?-thionucleoside, a preparation method therefor, a pharmaceutical composition comprising the same and an application thereof. Specifically, the present invention relates to a phosphamide derivative of 4?-thionucleoside, a preparation method therefor, a pharmaceutical composition comprising the same, a use thereof in the preparation of a medicine for preventing or treating abnormal cell proliferation diseases (for example, tumors or cancers and related diseases) or virus infectious diseases, and a method of using the same for preventing or treating abnormal cell proliferation diseases (for example, tumors or cancers and related diseases) or virus infectious diseases.
