The invention belongs to the technical field of medicines, and particularly relates to a dihydropteridine-6 (5H)-ketone skeleton compound as well as a preparation method and application thereof. The dihydropteridine-6 (5H)-ketone skeleton compound disclosed by the invention is an HIV-1 (Human Immunodeficiency Virus-1) non-nucleoside reverse transcriptase inhibitor; the invention also comprises pharmaceutical salts, hydrates, solvates, polycrystals or co-crystals of the compounds, precursors and derivatives with the same biological functions of the compounds, a preparation method of the compounds and application of a composition containing one or more of the compounds in preparation of related drugs for treating AIDS and the like. The result of an in-vitro cellular level anti-HIV-1 activity experiment shows that the micromolecule has relatively strong anti-HIV-1 biological activity, can remarkably inhibit virus replication in MT-4 cells infected by HIV-1 viruses, and has relatively low cytotoxicity.

The present disclosure provides methods for treating HBV infection using combination therapies in patients with serum HBsAg levels below 3000 IU / mL prior to treatment. The components of the combination therapies may include one or more of an anti-HBV antibody; an siRNA that targets an HBV mRNA; interferon-α; and a nucleos(t)ide reverse transcriptase inhibitor (NRTI).

A combination comprising a tricycle compound and use thereof in the preparation of a medicament for treating HBV. The combination is a combination of a compound of formula (I) or a pharmaceutically acceptable salt thereof and any one drug in the following groups a-c: a. a hepatitis B surface antigen inhibitor, b. a reverse transcriptase inhibitor, and c. a hepatitis B surface antigen inhibitor and a reverse transcriptase inhibitor.

The present invention relates to an improved process for the preparation of (((1-(6-amino-9H-purin-9-yl)propan-2-yloxy)methyl)(phenoxy)phosphoryloxy)methyl pivalate Compound (1) or its pharmaceutically acceptable salts thereof. The compound is useful as nucleotide reverse transcriptase inhibitor in therapy for diseases which respond to inhibition of protein kinase activity in humans in need thereof.

The invention belongs to the technical field of medicines, and particularly relates to a dihydropyridino [3, 4-D] pyrimidine compound as well as a preparation method and application thereof. The dihydropyrido [3, 4-D] pyrimidine compound disclosed by the invention is an HIV-1 (human immunodeficiency virus-1) non-nucleoside reverse transcriptase inhibitor. The invention also discloses pharmaceutical salts, hydrates, solvates, polycrystals or co-crystals of the compounds, precursors and derivatives with the same biological functions of the compounds, a preparation method of the compounds and application of a composition containing one or more of the compounds in related medicines for treating AIDS and the like. An in-vitro cellular level anti-HIV-1 activity experiment result shows that the small molecule compound has relatively strong anti-HIV-1 activity, can effectively inhibit the replication of HIV-1 viruses in MT-4 cells infected by the HIV-1 viruses, and has relatively low cytotoxicity.

The invention relates to a carbonyl-substituted pyrimidine derivative as well as a preparation method and application thereof, and belongs to the technical field of organic compound synthesis and medical application. The carbonyl-substituted pyrimidine derivative has a structure as shown in a formula I. The carbonyl-substituted pyrimidine derivative disclosed by the invention is novel in structure and shows good anti-HIV-1 activity as an HIV-1 inhibitor, and the EC50 value of the carbonyl-substituted pyrimidine derivative ranges from 4.28 nM to 274 nM and is obviously superior to that of a drug nevirapine (EC50 = 281 + / -38.7 nM) on the market.
