Biological Activity

Description D-pinitol (Methylinositol, Pinitol, 3-O-Methyl-D-chiro-inositol, D-(+)-Pinitol, Inzitol) is a naturally occurring compound derived from soy and has significant pharmacological activitites such as inhibition of the T-helpercell-1 response, antiviral, larvicidal, antiinflammatory, antihyperlipidemic, cardioprotective, inhibition of ovalbumin-induced airway inflammation and antioxidant.
In vitro

D-pinitol reduces the migration and the invasion of prostate cancer cells (PC3 and DU145) at noncytotoxic concentrations. Treatment of prostate cancer cells with D-pinitol reduces mRNA and cell surface expression of αvβ3 integrin. In addition, D-pinitol exerts its inhibitory effects by reducing focal adhesion kinase (FAK) phosphorylation, c-Src kinase activity and NF-κB activation[1].

In vivo D-pinitol exerts an acute and chronically-sustained antihyperglycaemic effect in the murine STZ-induced model of hypoinsulinaemic diabetes. The mechanism of action of D-pinitol does not augment the effect of insulin but might involve an interaction with part of a cellular signalling pathway that links insulin with glucose transport[2].

Protocol (from reference)

Cell Research:[1]
  • Cell lines: Human prostate cancer cell lines (PC3 and DU145)
  • Concentrations: 0, 1, 3, 10 and 30 μM
  • Incubation Time: 24 h
  • Method: For invasion assay, filters are precoated with 30 μL Matrigel basement membrane matrix for 30 min. The following procedures are the same for both migration and invasion assays. After the treatment with D-pinitol (0, 1, 3, 10 and 30 μM) for 24 h, cells are harvested and seeded to Transwell at 1 × 104 cells/well in serum-free medium and then incubated for 24 h at 37 °C in 5% CO2. Cells are then fixed in 3.7% formaldehyde for 5 min and stained with 0.05% crystal violet in PBS for 15 min. Cells on the upper side of the filters are removed with cotton-tipped swabs, and the filters are washed with PBS. Cells on the underside of the filters are examined and counted under a microscope.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

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.
