LifeTein’s Synthetic Scorpion Toxin Peptides Helped Scientists Unravel Chronic Pain Mechanisms

LifeTein’s synthetic Wasabi Receptor Toxin, Wasabi Receptor Toxin Mutants, Biotinylated Wasabi Receptor Toxin, and AlexaFluor-488 conjugated Wasabi Receptor Toxin and Mutants helped scientists unravel chronic pain mechanisms.
Researchers at the University of California, San Francisco (UCSF) have identified a scorpion toxin that targets the “wasabi receptor”. The wasabi receptor is an ion channel protein that is responsible for the sinus-clearing or eye-stinging pain experienced when eating wasabi or chopping onions.
It was found that the scorpion toxin, a peptide as the wasabi receptor toxin, or WaTx, activates the wasabi receptor TRPA1 and triggers this pain response to irritants. The WaTx peptide is a novel cell-penetrating peptide and can directly pass through the plasma membrane, without needing to traverse through channel proteins.
The WaTx peptide could be used to study chronic pain and inflammation and may lead to the development of novel non-opioid pain therapies. WaTx produces pain and pain hypersensitivity, but not neurogenic inflammation.

A click chemistry was reported about the formation of azides from primary amines


A click chemistry was reported about the formation of azides from primary amines. This powerful tool enables the reaction of just one equivalent of a simple diazotizing species, and fluorosulfuryl azide (FSO2N3), for the preparation of over 1,200 azides on 96-well plates in a safe and practical manner. This method greatly expands the number of accessible azides and 1,2,3-triazoles because the primary amine is one of the most abundant functional groups in small compounds, proteins and antibodies.
The method opens the door for numerous applications in drug screening and discovery. The cell penetration peptides can be easily introduced to conjugate with any azide containing drugs, compounds, antibodies, or proteins.
The cell penetration peptides (CPPs) are capable of delivering biologically active cargo to the cell interior. The desired therapeutic cargo could be attached to a CPP using the copper free click chemistry and then delivered to an intracellular target, thereby overcoming the entry restrictions set by the plasma membrane.

How to form the fibrillary structure using beta-amyloid peptides?


Aβ-(1–42) was dissolved to 1 mM in 100% hexafluoroisopropanol, hexafluoroisopropanol was removed under vacuum, and the peptide was stored at −20 °C. For the aggregation protocols, the peptide was first resuspended in dry Me2SO (DMSO) to 5 mM. For oligomeric conditions, F-12 (without phenol red) culture media was added to bring the peptide to a final concentration of 100 μM, and the peptide was incubated at 4 °C for 24 h. For fibrillar conditions, 10 mM HCl was added to bring the peptide to a final concentration of 100 μM, and the peptide was incubated for 24 h at 37 °C. ADDLS, amyloid derived diffusible ligands.
