🧪 Zombie Slayers: How Peptoid Antivirals Target and Tear Apart Virus Membranes 🧪

🌟 **Breakthrough:**
- Scientists have developed a peptoid-based antiviral therapy that effectively targets the lipids in virus membranes, mimicking the immune system and offering a promising direction for future antiviral drug development.
- This innovative approach has shown promise against three distinct viruses in laboratory tests by disrupting their membrane lipids.

🔬 **Viral Characteristics and Immune Defense:**
- Viruses are often described as biological “zombies” because they are neither fully living nor nonliving and can only multiply within a host, such as our body’s cells.
- The immune system naturally destroys pathogens with special molecules such as antibodies and antimicrobial peptides.

🌟 **Peptoid Research Advances:**
- Antimicrobial peptides are small protein-like molecules that are part of the immune system’s defense force but are not ideal drug candidates due to their cost, quick elimination from the body, and potential side effects.
- Researchers have developed lab-made molecules called peptoids that mimic the function of antimicrobial peptides but are more economical to produce and not easily degraded by the body.

📊 **Effectiveness of Peptoids:**
- Previous research by Annelise Barron’s team showed that certain peptoids could pierce and destroy the SARS-CoV-2 and herpes viruses.
- In this study, the team, joined by Kent Kirshenbaum and colleagues, tested the peptoids against three enveloped viruses (Zika, Rift Valley fever, and chikungunya virus) and one non-enveloped virus (coxsackie B3).
- The peptoids effectively inactivated the enveloped viruses by targeting the lipid phosphatidylserine (PS) in their membranes, but were ineffective against the non-enveloped virus.

🔬 **Mechanism of Action:**
- The peptoids used in the experiments included three linear peptoids and four new circularized versions with increased antiviral activity.
- The researchers created model virus membranes using common lipids, including PS, and found that the peptoids disrupted the membranes most effectively when PS was present in higher concentrations.
- This suggests that the peptoids specifically target PS, which is distributed differently in viral and human membranes, allowing the antiviral to preferentially attack the invader.

🌟 **Future Potential:**
- Understanding the mechanism of action of these peptoids can inform the design of future peptoid-based antiviral treatments.
- This approach could be used to create drugs already armed against the next emerging viral threat.
