Comparison with other venom peptides
Spider venom peptides share some characteristics with peptides from other venomous animals but differ in important ways. Cone snail venoms, for example, produced ziconotide (Prialt), the only venom-derived peptide currently approved for treating pain. Cone sna

- Spider venom peptides share some characteristics with peptides from other venomous animals but differ in important ways. Cone snail venoms, for example, produced ziconotide (Prialt), the only venom-derived peptide currently approved for treating pain. Cone snail peptides tend to be smaller and more rigid than spider peptides, making them easier to synthesize but potentially limiting their target diversity.
- Snake venoms contain peptides and larger proteins with potent effects on blood clotting and blood pressure. These have yielded drugs like captopril for hypertension. However, snake venom components are often larger and more immunogenic than spider peptides, complicating their therapeutic development.
- Scorpion venoms contain peptides similar to spider venoms in structure and function, which makes sense given the evolutionary relationship between these arachnids. Both scorpion and spider venoms contain numerous ICK peptides targeting ion channels. Research on both venom types often proceeds in parallel, with findings from one informing work on the other.
