SARS-CoV-2 Structure
Spike Glycoprotein (S) Get the virus into the cell
M-Protein Virus germination and envelope formation
Hemagglutinin-esterase (HE) May facilitate the
virus to initially adsorb the cell membrane
RNA and N Protein N protein is related to the
formation of nucleocapsid in RNA genome
E-Protein The smallest and most mysterious
Envelope

3
Use existing molecular libraries and databases
to screen for molecules that may have a
therapeutic effect on SARS-CoV-2.
Screen the existing broad-spectrum antiviral
drugs.
Develop specific drugs based on the genomic
information and pathological characteristics of
SARS-CoV-2.

Object of Specific Drugs
3-1. Target to the Host

• Enhance immune response - such as the release of
  interferon.

• Block the signal pathways required for virus
  replication.

• Target viral and cell surface receptor proteins
  (ACE2).

8
Object of Specific Drugs
3-2. Target to SARS-CoV-2

• Block the viruss binding to human cell
  receptors or inhibiting the virusself-assembly
  process - target to the structural proteins of
  the virus.

• Prevent viral RNA synthesis - target to the
  genetic material of the virus.

• Inhibit virus replication - target to key
  enzymes of the virus.

Monoclonal antibody/convalescent plasma for ACE2
Prevent the virus into the host cell.
1
Camostat mesylate Prevent SARS-CoV-2 into the
cell by acting on TMPRSS2.
2
?
Lopinavir-Ritonavir Inhibition of protease
activity of SARS-CoV-2.

Ribavirin- May inhibit mRNA capping.
?
RNA Synthesis Inhibitors Inhibits SARS-CoV-2 RNA
synthesis and replication.
5
RNA Synthesis Inhibitors
?
Neuraminidase Inhibitors (NAIs)-Interfere with
the release of progeny influenza virus from
infected host cells.
