Triterpenes from Poria cocos suppress growth and invasiveness of pancreatic cancer cells through the downregulation of MMP-7.[Pubmed: 23588713]
Poria cocos is a medicinal mushroom that is widely used in traditional Asian medicine.
METHODS AND RESULTS:
Here, we show that a characterized mixture of triterpenes extracted from P. cocos (PTE) and three purified triterpenes: pachymic acid (PA), Dehydropachymic acid (DPA) and polyporenic acid C (PPAC) suppress the proliferation of the human pancreatic cancer cell lines Panc-1, MiaPaca-2, AsPc-1 and BxPc-3. Moreover, the most effective compound, PA, only slightly affects the proliferation of HPDE-6 normal pancreatic duct epithelial cells. The anti-proliferative effects of PTE on BxPc-3 cells are mediated by the cell cycle arrest at G0/G1 phase. DNA microarray analysis demonstrated that PTE significantly downregulates the expression of KRAS and matrix metalloproteinase-7 (MMP-7) in BxPc-3 cells. In addition, PTE and PA suppress the invasive behavior of BxPc-3 cells. The inhibition of invasiveness by PTE and PA was associated with the reduction of MMP-7 at the protein level and the role of MMP-7 further confirmed by the gene silencing of MMP-7 which also suppressed the invasiveness of BxPc-3 cells.
CONCLUSIONS:
In conclusion, triterpenes from P. cocos demonstrate anticancer and anti-invasive effects on human pancreatic cancer cells and can be considered as new therapeutic agents in the treatment of pancreatic cancer.

Dehydropachymic acid decreases bafilomycin A1 induced β-Amyloid accumulation in PC12 cells[Pubmed: 28077330]
Abstract Ethnopharmacological relevance: Fuling, the sclerotium of Poria cocos, was frequently used in traditional Chinese medicine (TCM) formulae for Alzheimer's disease (AD) intervention over the past 10 centuries. And its extracts exhibited significant effects in both cellular and animal models of AD in previous studies. However, its mechanisms on prevention and treatment of AD have not been well elucidated yet. Aim of the study: To investigate the effect and corresponding mechanisms of Dehydropachymic acid, which is one of the major triterpenes in P. cocos, on the clearance of β-amyloid accumulation in bafilomycin A1 induced PC12 cells. Materials and methods: MTT assay was used to examine the DPA effect on the viability of PC12 cells stable transfected with pCB6-APP (PC12-APP). PC12-APP cells were treated with DPA at the concentration of 6.25, 12.5, 25μg/mL for 4h, and then co-treated with 50nmol/L bafilomycin A1 for 48h except the controls. The Aβ1-42 content in culture medium was determined by ELISA. The intracellular amount of APP, Aβ1-42, LC3, cathepsin D was measured by Western blotting and normalized to GAPDH loading control. The PC12 cells stable transfected with pSelect-LC3-GFP (PC12-LC3-GFP) was used in the fluorescence microscopy estimation of autophagosomes accumulation. The internal pH in lysosome was detected by LysoTracker Red staining. Results: DPA had no significant effect on the cell viability but could significantly decrease Aβ1-42 content in culture medium and eliminate the intracellular accumulation of APP and Aβ1-42 in bafilomycin A1 induced PC12-APP cells. Furthermore, DPA lowered the LC3-II/LC3-I ratio and reduced the GFP-labeled LC3 puncta which were elevated by bafilomycin A1. And the increase in internal pH of lysosome and decrease in mCatD amount in Bafilomycin A1 induced PC12-APP cells were restored by DPA treatment. These results indicated that DPA could restore the lysosomal acidification and recover the autophgic flux which is impaired by bafilomycin A1. Conclusions: DPA could effectively clear the accumulation of Aβ1-42 in bafilomycin A1 impaired PC12 cells through restoring the lysosomal acidification and recovering the autophgic flux. And these results highlight its therapeutic potential for AD treatment.

Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
Storage: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Triterpenes from the fungus Poria cocos and their inhibitory activity on nitric oxide production in mouse macrophages via blockade of activating protein-1 pathway.[Pubmed: 22083926]
Two new triterpenes, 29-hydroxydehydrotumulosic acid (1) and 29-hydroxyDehydropachymic acid (2), together with six known compounds, Dehydropachymic acid (3), dehydrotumulosic acid (4), 29-hydroxypolyporenic acid C (5), polyporenic acid C (6), tumulosic acid (7), and pachymic acid (8), were isolated from the dried sclerotia of Poria cocos.
METHODS AND RESULTS:
In the in vitro bioassays, these isolated compounds reduced, in a dose-dependent manner, nitric oxide (NO) production from lipopolysaccharide (LPS)-induced RAW 264.7 cells, with compounds 5 and 6, the IC(50) values of which were 16.8±2.7 and 18.2±3.3 μM, respectively, exhibiting the greatest inhibition activity. Further Western blot analysis conducted on cells pre-treated with compounds 5 and 6, and luciferase assays on activator protein 1-dependent gene expression revealed that the inhibited NO release was attributed to the reduced expression of iNOs (=inducible NO synthase) enzymes, which might be regulated via the blockade of activator protein-1 signaling pathway.
