How to use

In Vitro:

Intracellular Ca2+ imaging reveals that menthol induced both intracellular Ca2+ release and store-operated Ca2+ entry, with RQ-00203078 inhibiting each effect. RQ-00203078 (1-10 µM) inhibits HSC3 and HSC4 oral squamous carcinoma cell migration and invasion in vitro.

In Vivo:

RQ-00203078 (compound 36) demonstrates excellent in vivo activity in a dose dependent manner with an ED50 value of 0.65 mg/kg in the Icilin-induced wet-dog shakes model in rats after oral administration. Excellent oral exposure of RQ-00203078 (compound 36) is confirmed independently in rat pharmacokinetics studies at 3 mg/kg (p.o.) administration, with a Cmax value of 2300 ng/mL and 86% bioavailability.
