Product Data:
Biological target: Echinatin is a chalcone isolated from the Chinese herbal medicine Gancao with hepatoprotective and anti-inflammatory effects.
In vitro activity: Ech (Echinatin) significantly inhibited growth of ESCC cells in a dose- and time- dependent manner compared to control (Figure 1b–f). The concentration for inhibiting 50% of cell growth (IC50) of Ech was 15 µM for KYSE 30, 15 µM for KYSE 70, 6 µM for KYSE 410, 13 µM for KYSE 450, and 10 µM for KYSE 510. In the three-dimensional culture of ESCC cells, colony numbers and sizes were decreased by treatment with Ech in KYSE 30 and KYSE 450 cells (Figure 1g).

In vivo activity: This study pretreated mice with echinatin or MCC950, a best-studied selective inhibitor of NLRP3, and then conducted i.p. injection of LPS. Proinflammatory cytokines and neutrophils in peritoneal lavage fluids were measured. The data show that echinatin effectively attenuated LPS-induced IL-1β and TNF-α production, which was equivalent to the inhibitory effect of MCC950 (Figure 5, A and B). Moreover, consistent with the inhibitory effects of echinatin on proinflammatory cytokines, the proportion and the number of neutrophils in peritoneal lavage cells from mice pretreated with echinatin was also reduced (Figure 5, C and D).
