Pyrrolidine dithiocarbamate and nordihydroguaiaretic acid show promise for treating influenza. These compounds reduce viral load and toxic superoxide production, suggesting potential as chemotherapy drugs.
Area of Science:
- Virology
- Immunology
- Pharmacology
Background:
- Influenza virus infection triggers apoptosis and pro-inflammatory responses.
- Macrophages produce toxic superoxide, contributing to influenza pathogenesis.
Purpose of the Study:
- To investigate the potential of pyrrolidine dithiocarbamate and nordihydroguaiaretic acid as influenza therapeutics.
- To assess their effects on viral proliferation and superoxide production.
Main Methods:
- Treatment of influenza virus-infected cells with pyrrolidine dithiocarbamate and nordihydroguaiaretic acid.
- Measurement of viral proliferation and superoxide levels.
Main Results:
- Both compounds inhibited influenza virus proliferation.
- Pyrrolidine dithiocarbamate and nordihydroguaiaretic acid scavenged toxic superoxide.
Conclusions:
- Pyrrolidine dithiocarbamate and nordihydroguaiaretic acid demonstrate antiviral activity against influenza.
- These compounds are potential candidates for influenza chemotherapy due to their ability to inhibit viral replication and reduce oxidative stress.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
