3'-Hydroxypterostilbene

Catalog No.S3940 Synonyms: 3'-HPT

For research use only.

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. 3'-Hydroxypterostilbene, a natural pterostilbene analogue, effectively inhibits the growth of human colon cancer cells (IC50s of 9.0, 40.2, and 70.9 µM for COLO 205, HCT-116, and HT-29 cells, respectively) by inducing apoptosis and autophagy. 3'-Hydroxypterostilbene inhibits the PI3K/Akt/mTOR/p70S6K, and p38MAPK pathways and activates the ERK1/2, JNK1/2 MAPK pathways.

Description 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. 3'-Hydroxypterostilbene, a natural pterostilbene analogue, effectively inhibits the growth of human colon cancer cells (IC50s of 9.0, 40.2, and 70.9 µM for COLO 205, HCT-116, and HT-29 cells, respectively) by inducing apoptosis and autophagy. 3'-Hydroxypterostilbene inhibits the PI3K/Akt/mTOR/p70S6K, and p38MAPK pathways and activates the ERK1/2, JNK1/2 MAPK pathways.

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].

Protocol (from reference)

Cell Research:

[1]

  • Cell lines: COLO 205 cells
  • Concentrations: 5-100 µM
  • Incubation Time: 24 h
  • Method:

    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.

Animal Research:

  • Animal Models: nude mice bearing COLO 205 tumor xenografts
  • Dosages: 10 mg/kg
  • Administration: i.p.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
