生物活性

製品説明 3'-Hydroxypterostilbene (3'-HPT) is one of the active constituents of Sphaerophysa salsula and Pterocarpus marsupium which may be useful in treating different types of haematological malignancies.
in vitro 3'-Hydroxypterostilbene decreases cell growth in cultured human colon cancer cells (COLO 205, HCT-116, and HT-29) in a dose-dependent manner, with IC50 values of 9.0, 40.2, and 70.9 µM, respectively. 3'-Hydroxypterostilbene effectively inhibits the growth of human colon cancer cells by inducing apoptosis and autophagy. Treatment with HPSB causes reduction of mitochondrial membrane potential and induction of caspase-3 and caspage-9, which is associated with the degradation of DFF-45 and PARP, precedes the onset of apoptosis. It significantly down-regulates phosphatidylinositol 3-kinase (PI3K)/Akt and mitogen-activated protein kinases (MAPKs) signalings including decreased the phosphorylation of mammalian target of rapamycin (mTOR)[1].
in vivo 3'-Hydroxypterostilbene by i.p. injection has anti-tumor efficacy gainst colon cancer through the inhibition of inflammation, metastasis, and angiogenesis as well as through the induction of apoptosis[1].

実験の流れ

For sub-G1 cell population analysis, COLO 205 cells (2×105 cells/mL) are cultured in 12 well and treatment with various concentrations of pterostilbene or 3′-hydroxypterostilbene for 24 h. The cells are then harvested, washed with PBS, resuspended in 200 µL of PBS, and fixed in 800 µL of iced 100% ethanol at -20°C. After being left to stand overnight, the cell pellets are collected by centrifugation, resuspended in 1 mL of hypotonic buffer (0.5% Triton X-100 in PBS and 0.5 µg/mL RNase) with PI (50 µg/mL) and incubated at 37°C in the dark for 30 min. Fluorescence emitted from the PI-DNA complex is quantitated after excitation of the fluorescent dye.
