Mechanism of Action

Targets/IC₅₀/Ki	hTRPA1 ^[1] 454 nM
In vitro	Cardamonin selectively blocks TRPA1 activation while does not interact with TRPV1 nor TRPV4 channel. A concentration-dependent inhibitory effect is observed with IC50 of 454 nM. This compound does not significantly reduce HEK293 cell viability, nor does it impair cardiomyocyte constriction^[1]. In vitro, this chemical (25 and 50 μM) concentration dependently inhibits endothelium permeability and down-regulates phosphorylation of P38 in rat lung microvascular endothelial cells induced by lipopolysaccharide (LPS). In RAW 264.7 macrophage cells, it also shows selective inhibition of P38 phosphorylation induced by LPS^[2]. This compound inhibits the growth of several cancer cell types including breast cancer, glioblastoma, ovarian, prostate, and lung. Treatment of this chemical in CRC cell lines induces cell cycle arrest mostly in the S phase of cell cycle. It activates both apoptosis and induces cell cycle arrest to inhibit the cell proliferation. This natural product is known to inhibit various signaling pathways which play a major role in the process of inflammation and cancer. It inhibits the phosphorylation and translocation of both STAT3 and NF-κB. It also inhibits angiogenesis through downregulation of miR-21 expression^[3].
In vivo	Cardamonin (30 and 100 mg/kg) significantly elevates the survival rate of septic mice, alleviates ALI and lung microvascular leak, and lowers the serum levels of proinflammatory cytokines TNF-α, IL-1β,and IL-6^[2]. This compound inhibits Azoxymethane-induced colorectal cancer (CRC). Its treatment inhibits the tumor incidence, tumor multiplicity, Ki-67 and β-catenin positive cells. The preclinical pharmacokinetics and ADME characterization of this chemical in mice reports that it is highly permeable with an effective permeability value in ileum is (P_eff) 3 × 10⁻⁴ which is highly significant. Within 30 minutes of oral dosing, it is distributed to various tissues^[3].
