Description

Umbellulone is an active constituent of the leaves of Umbellularia californica. Umbellulone stimulates the TRPA1 channel in a subset of peptidergic, nociceptive neurons, activating the trigeminovascular system via this mechanism[1].

IC50 & Target

TRPA1 channel[1]
In Vitro

Umbellulone, from μM to sub-mM concentrations, selectively stimulates transient receptor potential ankyrin 1-expressing HEK293 cells[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Umbellulone Related Antibodies
In Vivo

Umbellulone (50–250?nM/5ul) causes an acute nocioceptive response in a dose-dependent manner in Trpa1+/+ mice[1].
Umbellulone (150?μg/kg; intravenous or intranasal) do not affect systemic blood pressure[1].
Umbellulone (30-150 μg/kg; i.v.) increases meningeal blood flow in a dose-dependent manner[1].

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.
