生物活性

Mavatrep (JNJ-39439335) is an orally active, selective and potent TRPV1 antagonist with high affinity for hTRPV1 channels (Ki=6.5 nM). Mavatrep antagonizes capsaicin-induced Ca influx with an IC50 value of 4.6 nM. Mavatrep can be used in some studies of neuropathic pain.

Solid

体外研究(In Vitro)

Mavatrep (series of decreasing concentrations from 1 μM; 25 min) inhibits capsaicin-induced Ca influx in HEK293 cells expressing TRPV1 channels.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.
