Problems solved by technology

[0007] Under the influence of many factors such as the deterioration of the global environment and warming, the dengue fever epidemic has been expanding in recent years, but there is currently no effective vaccine for preventing the occurrence and prevalence of dengue fever, and there is no effective anti-dengue virus drug available for clinical treatment For dengue fever, the current clinical treatment is mainly intensive supportive therapy, in which maintaining fluid balance is the main means
These limited means cannot cope with the high mortality rate (~5%) of DHF and DSS caused by dengue virus infection, so the drug research on dengue fever disease caused by dengue virus infection is extremely important and urgent

Abstract

The invention discloses use of a dipeptide analogue, and particularly relates to use of compounds in formulas (I) and (II), a stereisomer or a pharmaceutically acceptable salt thereof in pharmaceutical aspects. The compounds shown in the formulas (I) and (II) can be utilized as drugs for treating and preventing a disease caused by a dengue fever virus, and simultaneously can become the drugs for treating and preventing the disease caused by other flaviviruses, such as a yellow fever disease, hepatitis c, Japanese encephalitis, forest encephalitis, a disease caused by west nile virus infection, or aids caused by a human immunodeficiency virus (HIV) and the like.

Description

technical field [0001] The invention belongs to the field of medicinal chemistry, and specifically relates to the application of dipeptide analog compounds, stereoisomers, or pharmaceutically acceptable salts thereof in pharmacy. Background technique [0002] The compound of formula (I) has been used as the substrate of methionine aminopeptidase for drug screening of angiogenesis (Ying Zhou, Xiao-Chuan Guo, Tian Yi, Tadashi Yoshimoto, Dehua Pei Analytical Biochemistry 2000, 280, 159-165. ) [0003] [0004] And formula (II) is the raw material of formula (I) (Ying Zhou, Xiao-Chuan Guo, Tian Yi, Tadashi Yoshimoto, Dehua Pei Analytical Biochemistry 2000, 280, 159–165.) [0005] [0006] Dengue fever disease includes dengue fever (dengue fever, DF), dengue hemorrhagic fever (dengue hemorrhagic fever, DHF) and dengue shock syndrome (dengue shock syndrome, DSS) symptoms, it is caused by the flaviviridae dengue virus (dengue virus, DENV) infection. Dengue fever is mainly ...
