Anti-Inflammatory Peptides From Insect, Spider, and Scorpion Venoms: A Systematic Review
A systematic review of 171 studies found that peptides from arthropod venoms — including those from bees, scorpions, spiders, and crabs — have significant anti-inflammatory activity, primarily by reducing pro-inflammatory cytokines.
Quick Facts
What This Study Found
From 171 reviewed studies, arthropod-derived peptides from 9 animal groups demonstrated anti-inflammatory activity, primarily by decreasing pro-inflammatory cytokines in vitro and in vivo, with some also exhibiting anticancer properties.
Key Numbers
171 studies; 9 peptide families; sources: ants, bees, wasps, shrimp, crabs, scorpions, spiders, ticks, centipedes
How They Did This
Systematic review following PRISMA guidelines. PubMed, Scopus, Web of Science, and Google Scholar searched with no publication date limit. 171 studies met inclusion/exclusion criteria for data extraction.
Why This Research Matters
Current anti-inflammatory drugs often have significant side effects. Arthropod venom peptides offer a diverse library of natural anti-inflammatory molecules that could lead to new, more targeted treatments with fewer adverse effects.
The Bigger Picture
Venom-derived peptides are an expanding frontier in drug discovery. Nature has optimized these molecules over millions of years of evolution, creating potent and selective bioactive compounds. This review highlights their under-explored potential for treating inflammatory and neoplastic diseases.
What This Study Doesn't Tell Us
Systematic review with no new experimental data. Most included studies used in vitro or animal models. Clinical translation of venom peptides faces significant challenges including toxicity, stability, and manufacturing. Human safety data is largely absent.
Questions This Raises
- ?Which arthropod venom peptides are closest to clinical development as anti-inflammatory drugs?
- ?Can synthetic versions of these peptides retain anti-inflammatory activity while eliminating toxicity?
- ?Could venom peptides with dual anti-inflammatory and anticancer properties address inflammatory cancers?

Evidence Hierarchy
Frequently Asked Questions
How can venomous animal peptides be anti-inflammatory?
Venom peptides evolved to modulate the victim's immune and nervous systems. Some components suppress inflammation — a property that, when isolated and refined, could be repurposed as targeted anti-inflammatory drugs without the full venom's toxic effects.
Are any venom-based drugs already in use?
Yes — examples include ziconotide (from cone snail venom) for pain and exenatide (from Gila monster saliva) for diabetes. The anti-inflammatory venom peptides reviewed here are earlier in development but follow the same drug-discovery approach.
