Morphiceptin
Morphiceptin is a four amino acid peptide derived from the ß-casomorphin, a protein fragment itself derived from the
digestion of milk protein casein. It is one of the most selective agonist for µ-opoid receptors.

GsMTx4
GsMTx4 has been isolated from the venom of the spider Grammostola rosea. This cationic hydrophobic polypeptide blocks mechanosensitive ion channels such as TRPC1 or TRPC6, without having any effect on whole-cell voltage-sensitive
currents. This toxin acts by perturbing the interface between the channel and the lipid bilayer without necessarily being
in physical contact with the channel. GsMTx4 also demonstrated to active TRPA1 channel at 1µM concentration.

Obtustatin
Obtustatin is a 41 amino acid disintegrin peptide isolated from the venom of the Vipera lebetina obtusa. It is a potent
(IC50 = 2 nM) and selective inhibitor of the binding of α1β1 integrin to collagen IV. Contrary to other known disintegrins, it does not contain the classical RGD sequence. Does not show inhibitory activity toward other integrins, including α2β1,
αIIbβ3, αvβ3, α4β1, α5β1, α6β1, and α9β1, α4β7 integrins. Obtustatin potently inhibits angiogenesis in chicken and in
mouse model and reduces tumor development by half.
