Pristimerin

Research use only, not for human use.

Pristimerin has anticancer activity, treatment with Pristimerin may be a potential strategy for the suppression of hypoxia-induced metastasis through the reversal of hypoxia-induced stem cell characteristics and EMT in cancer cells.

Pristimerin has anticancer activity , treatment with Pristimerin may be a potential strategy for the suppression of hypoxia-induced metastasis through the reversal of hypoxia-induced stem cell characteristics and EMT in cancer cells. Pristimerin down-regulates the expression of pro-inflammatory mediators through blocking of NF-κB activation by inhibiting interconnected ROS/IKK/NF-κB signaling pathways, can effectively inhibit both arthritic inflammation and cartilage and bone damage in the joints.

Pristimerin inhibits the activity of purified MGL with an IC50 of 93±8 nM and that of non-purified MGL (cell lysates of MGL-transfected HeLa cells) with an IC50 of 398±68 nM. Pristimerin inhibits MGL through a mechanism that is rapid, reversible and non-competitive. The binding of pristimerin to MGL might be strengthened by formation of a polar interaction with a regulatory cysteine, possibly Cys208. Pristimerin inhibits HFLS-RA and HUVEC cell viability in a dose- and time-dependent manner. Pristimerin decreases VEGF-induced autophosphorylation of VEGFR2 and attenuates the activation of the VEGF-induced VEGFR2-mediated signaling pathway .

Pristimerin inhibits inflammation and tumor angiogenesis. Pristimerin significantly reduces vessel density in synovial membrane tissues of inflamed joints and reduces the expression of pro-angiogenic factors in sera, including TNF-α, Ang-1, and MMP-9.
