Abstract

The invention belongs to the field of antivirus in medical chemistry, and relates to preparation of non-cyclic nucleotide phosphoamides and salts thereof and application of the non-cyclic nucleotide phosphoamides and salts thereof in treating human immunodeficiency virus (HIV), hepatitis B, hepatitis B virus (HBV) and other virus infection diseases. The non-cyclic nucleotide phosphoamides, and isomers, pharmaceutically acceptable salts, hydrates, solvates or crystals thereof have the general formula I of which the structure is disclosed in the specification. The invention also provides a pharmaceutical composition containing the compounds and isomers, pharmaceutically acceptable salts, hydrates, solvates or crystals thereof, and application of the compounds or composition in treating and / or preventing HIV and HBV infection. The compounds provided by the invention have the advantages of favorable anti-HIV and HBV activities, low oral dosage and low toxicity.

Description

technical field [0001] The invention belongs to the field of medicinal chemistry and anti-virus, and in particular relates to a new class of deuterated acyclic nucleotide phosphoramide compounds or their isomers and compounds containing deuterated acyclic nucleotide phosphoramide compounds or their isomers Combination medicine is used as an antiviral application, especially for treating HIV-infected or / and HBV-infected patients. Background technique [0002] Human immunodeficiency virus type 1 (HIV-1, AIDS) remains one of the most contagious diseases in the world. Although humans have developed a variety of drugs and methods for prevention and treatment, the current situation is that HIV-1 infection is still in a pandemic state. An estimated 39 million people worldwide are infected with AIDS, and about 4 million die each year. In 2009 alone, there were approximately 2.7 million new HIV infections. There are currently 22 drugs approved by the FDA for the treatment of AIDS,...
