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 ?M, 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].
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].

3'-Hydroxypterostilbene Inhibits 7,12-Dimethylbenz[a]anthracene (DMBA)/12-O-Tetradecanoylphorbol-13-Acetate (TPA)-Induced Mouse Skin Carcinogenesis
Phytomedicine 2021 Jan;81:153432.PMID:33310310DOI:10.1016/j.phymed.2020.153432.
Background: A natural pterostilbene analogue isolated from the herb Sphaerophysa salsula, 3'-Hydroxypterostilbene (HPSB), exhibits antiproliferative activity in several cancer cell lines; however, the inhibitory effects of HPSB on skin carcinogenesis remains unclear. Purpose: The aim of this study was to evaluate the inhibitory effects of HPSB on two-stage skin carcinogenesis in mice and its potential mechanism. Study design and methods: This study investigated the anti-inflammatory and anti-tumor effects of HPSB in the 12-O-tetradecanoylphorbol-13-acetate (TPA)-stimulated acute skin inflammation and 7,12-dimethylbenz[a]anthracene (DMBA)/TPA-induced two-stage skin carcinogenesis model. In addition, the effects of HPSB on the modulation of the phase I and phase II metabolizing enzymes in the DMBA-induced HaCaT cell model were investigated. Results: The results provide evidence that topical treatment with HPSB significantly inhibits TPA-induced epidermal hyperplasia and leukocyte infiltration through the down-regulation of cyclooxygenase-2 (COX-2), matrix metalloprotein-9 (MMP-9), and ornithine decarboxylase (ODC) protein expression in mouse skin. Furthermore, HPSB suppresses DMBA/TPA-induced skin tumor incidence and multiplicity via the inhibition of proliferating cell nuclear antigen (PCNA), Cyclin B1 and cyclin-dependent kinase 1 (CDK1) expression in the two-stage skin carcinogenesis model. In addition, pretreatment with HPSB markedly reduces DMBA-induced cytochrome P450 1A1 (CYP1A1) and cytochrome P450 1B1 (CYP1B1) gene expression in human keratinocytes; however, HPSB does not significantly affect the gene expression of the phase II enzymes. Conclusion: This is the first study to show that topical treatment with HPSB prevents mouse skin tumorigenesis. Overall, our study suggests that natural HPSB may serve as a novel chemopreventive agent capable of preventing carcinogen activation and inflammation-associated tumorigenesis.
3'-Hydroxypterostilbene Potently Alleviates Obesity Exacerbated Colitis in Mice

Epidemiological surveys show that obesity and the western diet increase the risk of colitis. Studies have also confirmed that the high-fat-diet (HFD) promoted the deterioration of colitis-related indicators in mice. Compared with stilbenoids, the results showed that 3'-Hydroxypterostilbene (HPSB) was found to be the most effective inhibitor for the antiadipogenesis and anti-inflammation. However, its role in ameliorating obesity-promoted colitis is still unknown. We intend to investigate the protective effect and related molecular mechanisms of HPSB on HFD promoted dextran sodium sulfate (DSS)-induced colitis in mice. The results indicate that colitis in the HFD+DSS group tends to be more apparent in the DSS-only group, while feeding 0.025% of HPSB at different stages can improve the colitis induced by HFD+DSS. HPSB significantly reduced the levels of interleukin-6 (IL-6) and monocyte chemoattractant protein-1 (MCP-1) induced by HFD+DSS in mice. Furthermore, the Western blotting revealed that the administration of HPSB significantly downregulated cyclooxygenase-2 (COX-2), plasmalemma vesicle-associated protein-1 (PV-1), and phospho-signal transducer and activator of transcription 3 (p-STAT3) expressions in HFD+DSS treated mice. Presented results reveal that HPSB is a novel functional agent capable of preventing HFD exacerbated colitis.

3'-Hydroxypterostilbene (trans-3,5-dimethoxy-3',4'-hydroxystilbene) presents in Sphaerophysa salsula, Pterocarpus marsupium, and honey bee propolis and has been reported to exhibit several biological activities. Herein, we aimed to explore the chemopreventive effects of dietary 3'-Hydroxypterostilbene and underlying molecular mechanisms on colitis-associated cancer using the azoxymethane (AOM)/dextran sodium sulfate (DSS) model. 3'-Hydroxypterostilbene administration effectively ameliorated the colon shortening and number of tumors in AOM/DSS-treated mice (3.2 ± 1.2 of the high-dose treatment versus 13.8 ± 5.3 of the AOM/DSS group, p < 0.05). Molecular analysis exhibited the anti-inflammatory activity of 3'-Hydroxypterostilbene by a significant decrease in the levels of inducible nitric oxide synthase, cyclooxygenase-2, and interleukin-6 (IL-6) (p < 0.05). Moreover, dietary 3'-Hydroxypterostilbene also significantly diminished IL-6/signal transducer and activator of transcription signaling and restored colonic suppressor of cytokine signaling 3 levels in the colonic tissue of mice (p < 0.05). Collectively, these results demonstrated for the first time the in vivo chemopreventive efficacy and molecular mechanisms of dietary 3'-Hydroxypterostilbene against colitis-associated colonic tumorigenesis.
Biological actions and molecular effects of resveratrol, pterostilbene, and 3'-Hydroxypterostilbene
J Food Drug Anal 2017 Jan;25(1):134-147.PMID:28911531DOI:10.1016/j.jfda.2016.07.004.
Stilbenes are a class of polyphenolic compounds, naturally found in a wide variety of dietary sources such as grapes, berries, peanuts, red wine, and some medicinal plants. There are several well-known stilbenes including trans-resveratrol, pterostilbene, and 3'-Hydroxypterostilbene. The core chemical structure of stilbene compounds is 1,2-diphenylethylene. Recently, stilbenes have attracted extensive attention and interest due to their wide range of health-beneficial effects such as anti-inflammation, -carcinogenic, -diabetes, and -dyslipidemia activities. Moreover, accumulating in vitro and in vivo studies have reported that stilbene compounds act as inducers of multiple cell-death pathways such as apoptosis, cell cycle arrest, and autophagy for chemopreventive and chemotherapeutic agents in several types of cancer cells. The aim of this review is to highlight recent molecular findings and biological actions of trans-resveratrol, pterostilbene, and 3'-Hydroxypterostilbene.
Pterostilbene and Its Derivative 3'-Hydroxypterostilbene Ameliorated Nonalcoholic Fatty Liver Disease Through Synergistic Modulation of the Gut Microbiota and SIRT1/AMPK Signaling Pathway
J Agric Food Chem 2022 Apr 27;70(16):4966-4980.PMID:35416649DOI:10.1021/acs.jafc.2c00641.
Nonalcoholic fatty liver disease (NAFLD) is a recent chronic liver disease common in many developed countries and is closely associated with metabolic syndrome, such as obesity and insulin resistance. The present study was performed to investigate the effects of pterostilbene (Pt) and its derivative 3'-Hydroxypterostilbene (OHPt) on free fatty acids (FFA)-induced lipid accumulation in HepG2 cells and high-fat diet (HFD)-induced NAFLD in C57BL/6J mice. The results showed that Pt and OHPt significantly ameliorated FFA-induced steatosis in HepG2 cells and enhanced lipolysis through the upregulation of SIRT1/AMPK and insulin signaling pathways. In the in vivo study, Pt and OHPt treatment resulted in reduced hepatic lipid droplets accumulation. The data showed that Pt and OHPt upregulated the SIRT1/AMPK pathway and subsequently downregulated the protein expression of SREBP-1 to activate fatty acid (FA) β-oxidation to inhibit FA synthesis. Pt and OHPt administration activated the insulin signaling pathway and further ameliorated the insulin resistance and liver function in the HFD-fed mice. Furthermore, Pt and OHPt markedly increased the numbers of Oscillospira and decreased the numbers of Allobaculum, Phascolarctobacterium, and Staphylococcus compared with those in the HFD group. These robust results indicate that Pt and OHPt are able to possess potential health benefits in improving insulin resistance and hepatic steatosis by promoting healthy populations or abundances of considered vital microbiota. Besides, OHPt is more effective than Pt, which might have promising chemotherapeutic effects for future clinical application.
