Area of Science:

  • Virology
  • Pharmacology
  • Molecular Biology

Background:

  • Enterovirus 71 (EV71) poses a significant global health risk.
  • Currently, no approved antiviral drugs exist for EV71-induced diseases.
  • Corydaline is known for antiallergic and antinociceptive effects, but its antiviral properties are unexplored.

Purpose of the Study:

  • To investigate the potential anti-EV71 activity of corydaline.
  • To elucidate the mechanism underlying corydaline's effect on EV71 replication.

Main Methods:

  • In vitro assessment of corydaline's impact on EV71 structural and non-structural proteins.
  • Analysis of EV71 replication inhibition.
  • Evaluation of corydaline's effect on COX-2 expression and MAPK signaling pathways (JNK, P38, ERK).
Keywords:

Main Results:

  • Corydaline significantly suppressed the expression of EV71 viral proteins.
  • Corydaline inhibited EV71 replication in vitro.
  • The antiviral mechanism involves the suppression of COX-2 expression and the phosphorylation of JNK MAPK and P38 MAPK, but not ERK MAPK.

Conclusions:

  • Corydaline demonstrates promising antiviral activity against EV71.
  • Corydaline's mechanism involves modulation of COX-2 and MAPK signaling pathways.
  • Corydaline represents a potential lead compound or supplement for developing novel anti-EV71 therapeutics.
