Abstract

The invention discloses a thiazole (piperazine) azululanone azasugar derivative, and provides a synthesis method of the derivative and application of the derivative to preparation of an anti-HIV (Human Immunodeficiency Virus) medicinal preparation. A compound has high anti-HIV activity, and more administration options can be provided for clinical treatment of AIDS.

Description

technical field [0001] The present invention relates to an azasaccharide derivative compound and its synthesis method and its application in pharmaceutical preparations, in particular to thiazolyl (oxazin) alkanone azasaccharides, its synthesis method and its application in pharmaceutical preparations. Background technique: [0002] AIDS is acquired immunodeficiency syndrome (Acquired Immunodeficiency Syndrome, AIDS), is caused by human immunodeficiency virus (Human Immunodeficiency Virus, HIV) infection. There are three main classes of drugs currently used to treat AIDS: nucleoside reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors, and protease inhibitors. Because HIV has a very strong ability to mutate rapidly, patients will develop drug resistance shortly after taking certain anti-HIV drugs. For this reason, clinicians often use more than three different anti-HIV drugs in combination. Even so, patients will still develop obstinate drug re...
