β-thujaplicin

Synonyms: Hinokitiol, 4-Isopropyltropolone

β-Thujaplicin (β-TH, Hinokitiol, 4-Isopropyltropolone) is a toxic tropolone derivative present in the heartwood of western red cedar (Thuja plicata) and is used as a preservative and antimicrobial additive in a number of commercial goods. Hinokitiol is a component of essential oils isolated from Chymacyparis obtusa, reduces Nrf2 expression, and decreases DNMT1 and UHRF1 mRNA and protein expression, with anti-infective, anti-oxidative, and anti-tumor activities.

Description β-Thujaplicin (β-TH, Hinokitiol, 4-Isopropyltropolone) is a toxic tropolone derivative present in the heartwood of western red cedar (Thuja plicata) and is used as a preservative and antimicrobial additive in a number of commercial goods. Hinokitiol is a component of essential oils isolated from Chymacyparis obtusa, reduces Nrf2 expression, and decreases DNMT1 and UHRF1 mRNA and protein expression, with anti-infective, anti-oxidative, and anti-tumor activities.
In vitro
In vitro In lung cancer cells, hinokitiol inhibits cell proliferation by inducing the p53-independent DNA damage response, autophagy (not apoptosis), S-phase cell cycle arrest, and senescence. Hinokitiol induces autophagy in lung adenocarcinoma cells but not in human lung stromal fibroblasts. It induces cellular senescence in both human lung cancer cells and lung stromal fibroblasts[1]. Treatment with hinokitiol reveals a concentration-dependent inhibition of migration of B16-F10 melanoma cells. It appears to achieve this effect by reducing the expression of MMP-1 and by suppressing the phosphorylation of mitogen- activated protein kinase (MAPK) signaling molecules such as extracellular signal-regulated kinase (ERK) 1/2, p38 MAPK and c-Jun N-terminal kinases (JNK). On the other hand, hinokitiol treatment reverses IκB-α degradation and inhibits the phosphorylation of p65 nuclear factor kappa B (NF-κB) and cJun in B16-F10 cells. In addition, hinokitiol suppresses the translocation of p65 NF-κB from the cytosol to the nucleus, suggesting reduced NF-κB activation[2].
Cell Research Cell lines A549 cells
Concentrations 0.3125-10 µM
Incubation Time 24, 48, and 72 h
Method For trypan blue staining, 2×104 cells are cultured in 12-well plates overnight and then incubated with 0.3125-10 µM hinokitiol for 24, 48, and 72 h. At the indicated times, the cells are trypsinized and stained with trypan blue. The viable cells that excluded trypan blue are counted in a counting chamber.
In Vivo
In vivo Hinokitiol reduces tumor growth, potentially through the attenuation of tumorigenicity, and induces DNA damage and autophagy to suppress tumor progression[1]. In vivo study demonstrates that hinokitiol treatment significantly reduces the total number of mouse lung metastatic nodules and improves histological alterations in B16-F10 injected C57BL/6 mice[2].

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.
