Abstract

The present invention provides a 3-position functionalized N(O,S)-heteroindenes derivatives used in the preparation of anti-Zika virus drugs and a pharmaceutical composition, and relates to the technical field of pharmaceutical applications. The 3-position functionalized N(O, S)-heteroindenes derivatives of the present invention have a clear anti-Zika virus effect, and have obvious inhibitory activity on the replication of Zika virus; preliminary toxicity studies show that it has good The druggability shows that this kind of derivatives has a good application prospect as antiviral drugs.

Description

technical field [0001] The invention relates to the technical field of drug application, in particular to the application and pharmaceutical composition of 3-position functionalized N(O,S)-heteroindenyl derivatives in the preparation of anti-Zika virus drugs. Background technique [0002] Zika virus (Zikavirus, ZIKV) was first isolated in 1947 from the serum of monkeys in the Zika Forest of the Victoria River in Uganda. It belongs to the flavivirus genus transmitted by mosquitoes. 11kb, encoding an open reading frame (openreading frame, ORF), which can form a polyprotein. ZIKV infection can cause outbreaks of acute infectious diseases, mainly transmitted by Aedes aegypti mosquitoes. The first recorded case of human infection with Zika virus was in 1952. After a person is infected with Zika virus, the main clinical manifestations are rash, fever, muscle pain, non-suppurative conjunctivitis, and headache. In addition, after the outbreak of the Zika epidemic, more and more e...
