Description

OB-1 is a stomatin-like protein-3 (STOML3) oligomerization blocker. OB-1 is an effective inhibitor of the self-association of Stomatin, STOML1 and STOML2, but not podocin[1].

IC50 & Target

Stomatin, STOML1, STOML2, STOML3[1]
In Vitro

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.

In Vivo

OB-1 (250-500 pmol per paw; s.c.; once) reversibly reduces the sensitivity of mechanically gated currents in sensory neurons and silence mechanoreceptors in mice[1].
OB-1 (250 pmol per paw; s.c.; once) alleviates painful diabetic neuropathy in mice[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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
