Tetrahydropalmatine hydrochloride

Catalog No.S3854 Synonyms: Gindarine hydrochloride, 1-Tetrahydropalmitine HCl

For research use only.

Tetrahydropalmatine (THP, Gindarine, 1-Tetrahydropalmitine) is an isoquinoline alkaloid found in several different plant species, mainly in the Corydalis genus (Yan Hu Suo), but also in other plants such as Stephania rotunda. It is a potent muscle relaxant. Tetrahydropalmatine hydrochloride acts through inhibition of amygdaloid release of dopamine to inhibit an epileptic attack in rats.

Biological Activity

Description Tetrahydropalmatine (THP, Gindarine, 1-Tetrahydropalmitine) is an isoquinoline alkaloid found in several different plant species, mainly in the Corydalis genus (Yan Hu Suo), but also in other plants such as Stephania rotunda. It is a potent muscle relaxant. Tetrahydropalmatine hydrochloride acts through inhibition of amygdaloid release of dopamine to inhibit an epileptic attack in rats.
In vitro

Tetrahydropalmatine inhibits the LPSinduced production of COX-2 protein and mRNA in a dose-dependent manner. It suppresses activation of the NF-kB signaling pathway, which results in regulation of IL-8 expression and specifically blocks the ERK1=2 and p38 MAPK signaling pathways[1]. L-THP results in p53 independent apoptosis via down-regulating XIAP protein by inhibiting MDM2 associated with proteasome-dependent pathway and increased sensitivity of EU-4 cells against doxorubicin. L-THP causes activation of caspase and resulted in apoptosis[2]. l-THP possesses a blocking effect on dopamine D1 and D2 receptors and voltage-sensitive Ca2+ channels[3].

In vivo l-THP could attenuate the locomotor-stimulating effects of oxycodone and inhibit the development and expression of oxycodone behavioral sensitization[3].

Protocol (from reference)

Cell Research:[1]
  • Cell lines: THP-1 cells
  • Concentrations: 0.2, 1, or 2 mM
  • Incubation Time: 24 h
  • Method: Cell viability is examined by MTT assay. In brief, THP-1 cells are seeded at a density of 5×104 cells/mL in 96-well plates. Each batch of cells includes a nontreated group as a control. Tetrahydropalmatine (0.2, 1, or 2 mM) and LPS (2 mg/mL) are then added to each well, after which the plates are incubated for 24 hours at 37℃ under 5% CO2. Next, MTT solutions (5 mg/mL) are added to each well, and the samples are then cultured for an additional 4 hours. The supernatant is then discarded, and 100 mL of dimethylsulfoxide is added to each well. Next, the optical density is read at 590 nm.
Animal Research:[3]
  • Animal Models: Kunming mice
  • Dosages: 6.25, 12.5, and 18.75 mg/kg
  • Administration: administered intragastrically

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.
