Embodiment 1

[0046] Example 1. Principle of Screening Model

[0047] Filovirus entry into host cells is the first step in virus infection, and inhibiting virus entry can effectively block virus infection. The glycoprotein (Glycoprotein, GP) on the surface of the filovirus envelope is a key protein in the process of filovirus entry.

[0048] We synthesized the envelope GP gene of Zaire type Ebola virus (EBOV-GP, Gene Accession No.L11365), the envelope GP gene of Sudan type Ebola virus (SUDV-GP, Gene Accession No.FJ968794.1) , Tai Forest type Ebola virus envelope GP gene (TAFV-GP, Gene Accession No.FJ217162.1), Marburg virus envelope GP gene (Marburg-GP, Gene Accession No.NC_001608.3) and Cueva virus Envelope GP gene (Cueva-GP, Gene Accession No. JF828358). Expression of GP protein plasmid and pNL4-3-Luc-R by co-transfection - E. - , Filovirus GP can be obtained as a filovirus recombinant virus HIV / Filovirus-GP that coats the HIV core[Chen Q,Tang K,Zhang X,Chen P,Guo Y.Establishment of p...

[0049] Example 2. Inhibition of Sclareol and Sclareolide to Filamentous Recombinant Virus Infection

[0050] In the present invention, Zaire type Ebola virus (EBOV, Gene Accession No.L11365), Sudan type Ebola virus (SUDV, Gene Accession No.FJ968794.1), Tai Forest type Ebola virus ( Anti-filovirus infection of TAFV, Gene Accession No.FJ217162.1), Marburg virus (Gene Accession No.NC_001608.3) and Cueva virus (Gene Accession No.JF828358) to sclareol and sclareolide Action for pharmacological activity evaluation:

Abstract

The invention discloses the application of sclareol and sclareolide in anti-filovirus infection. The present invention includes the application of sclareol or / and sclareolide in the prevention or treatment of filovirus infection or combined application with other antiviral drugs.

Description

technical field [0001] The invention relates to the application of sclareol and sclareolide in resisting filovirus infection, and belongs to the technical field of medicine. The present invention includes the single or combined application of sclareol and sclareolide in preventing or treating filovirus infection. Background technique [0002] Filoviruses belong to the Filoviridae family, also known as Filoviruses, which are divided into three genera, namely Ebolavirus, Marburgvirus and Cuevavirus. Viruses (Cuevavirus). Ebola virus disease (EVD), caused by Ebola virus, is a major and severe infectious disease that seriously endangers public safety and human health, with a fatality rate as high as 25%-90% [Sanchez, A.; Geisbert, TW .; Feldmann, H. Filoviridae: Marburg and Ebola viruses. In: Knipe, DM.; Howley, PM., editors. Fields virology. Philadelphia: Lippincott Williams & Wilkins; 2006.1409-1448.]. Marburg virus is also fatal, with a fatality rate of 50-80% [Nonfatal ca...
