背景说明 |
Cardamonin是hTRPA1阳离子通道拮抗剂,也是NF-kB抑制剂。 |
生物活性 |
(E)-Cardamonin ((E)-Cardamomin) is a novel antagonist of hTRPA1 cation channel with an IC50 of 454 nM.[1-2] |
IC50 |
IC50: 454 nM (hTRPA1 cation channel)[1] |
In Vitro |
(E)-Cardamonin ((E)-Cardamomin) selectively blocksTRPA1 activation (IC50=454 nM) while does not interact with TRPV1 nor TRPV4 channel. Docking analysis of cardamonin demonstrates a compatible interaction with A-967079-binding site of TRPA1. (E)-Cardamonin ((E)-Cardamomin) does not significantly reduce HEK293 cell viability, nor does it impair cardiomyocyte constriction[1]. (E)-Cardamonin ((E)-Cardamomin) suppresses the expression of Tgase-2, cyclooxygenase-2 (COX-2), and p65 (nuclear factor-κB) in a concentration-dependent manner, and restores the expression of IκB in MG63 and Raw264.7 cells[2]. |
In Vivo |
(E)-Cardamonin ((E)-Cardamomin) (3-30 mg/kg, orally administered) significantly inhibits PBQ-induced writhing. CDN also produces a significant, dose-dependent increase in the withdrawal response latencies in carrageenan-induced hyperalgesia[2]. |
细胞实验 |
HEK293 cells are treated with (E)-Cardamonin ((E)-Cardamomin) (0-90 μM). The cells treated in the absence of the test compound are the negative control. After incubated for 24 h, Cell Titer-Glo reagent is added to the cells and Luminescence is acquired on the plate reader[1]. |
动物实验 |
Rats: The rats are divided into groups of six according to their nociceptive pressure thresholds, after which carrageenan (0.1 mL, 1%) is injected into the plantar surface of the left hind paw. The rats received vehicle or (E)-Cardamonin ((E)-Cardamomin) (3-30 mg/kg) or indomethacin (3 mg/kg) orally 2 h after carrageenan injection and are evaluated for paw hyperalgesia 0, 1 and 2 h after administration of compounds. Indomethacin is used as a positive control[2]. Mice: Acute pain is induced by an intraperitoneal injection of 0.2 mL of 0.02% PBQ 54 min after oral administration of (E)-Cardamonin ((E)-Cardamomin). Six minutes after the PBQ injection, the total number of writhes is counted for 6 min. The control animals received an appropriate volume of dosing vehicle (80% saline, 10% ethanol and 10% Tween 80). Indomethacin is used as a positive control[2]. |
