Biological Activity
Stomatin, STOML1, STOML2, STOML3[1]
OB-1 (3 h) reduces mechanotransduction currents in in N2a cells with an IC50 of 10 nM[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:C57Bl/6N mice[1]
-
Dosage:250-500 pmol per paw
-
Administration:Subcutaneous injection, once
-
Result:Over 40% of Aβ fibers (19/44) lacked a mechanosensitive receptive field, which was significantly different from that in vehicle-injected controls, where less than 7% (5/69 fibers) were found to be insensitive to mechanical stimuli. Reduced touch perception. Reversed tactile allodynia.

Animal Model:Eight-week-old C57Bl/6 mice, Streptozotocin (HY-13753) model[1]
-
Dosage:250 pmol per paw
-
Administration:Subcutaneous injection, once
-
Result:Substantially reversed the mechanical hypersensitivity 4 h after treatment.
