Biological Activity

Description Esculetin (Cichorigenin, Aesculetin) is a coumarin derivative found in various natural plant products with various biological and pharmaceutical properties including anti-edema, anti-inflammatory and anti-tumour effects. It inhibits lipoxygenases (LOs).
Targets
lipoxygenase [2]
In vitro

Esculetin decreases cell proliferation by inducing G1 phase cell cycle arrest, which is associated with the down-regulation of cyclin D1/CDK4 and cyclin E/CDK2 complexes by the activation of p27KIP[2]. Esculetin significantly inhibits proliferation of HCC cells in a concentration- and time-dependent manner and with an IC50 value of 2.24 mM. It blocks the cell cycle at S phase and induces apoptosis in SMMC-7721 cells with significant elevation of caspase-3 and caspase-9 activity, but does not affect caspase-8 activity. Esculetin treatment results in the collapse of mitochondrial membrane potential in vitro and in vivo accompanied by increased Bax expression and decreased Bcl-2 expression at both transcriptional and translational levels. Esculetin exerts in vitro and in vivo antiproliferative activity in hepatocellular carcinoma, and its mechanisms involved initiation of a mitochondrial-mediated, caspase-dependent apoptosis pathway[3].

In vivo Esculetin significantly decreases tumor growth in mice bearing Hepa1-6 cells. Tumor weight is decreased by 20.33, 40.37, and 55.42% with increasing doses of esculetin. Of note, esculetin has no obvious toxicity in this animal study[3]. In a rat experimental model of inflammatory bowel disease induced by trinitrobenzenesulfonic acid, esculetin at the dose of 5 mg/kg displays intestinal anti-inflammatory activity[4].

Protocol (from reference)

Cell Research:[1]
  • Cell lines: 3T3-L1 mouse embryo fibroblasts
  • Concentrations: 0, 50, 100, 200, 400, 800 μM
  • Incubation Time: 6, 12, 24, or 48 hours
  • Method: Tests are performed in 96-well plates. For mature adipocytes, cells are seeded (5000 cells/well), grown to confluency, induced to differentiate, and grown to maturation. For preadipocytes, a seeding density of 2500 cells/well is used, and cells are cultured overnight before treatment. Cells are incubated with either DMSO or increasing concentrations of esculetin for 6, 12, 24, or 48 hours. For the post-confluent preadipocytes, a seeding density of 2500 cells/well is used, and cells are grown to confluency before treatment. Esculetin (100 or 200 μM) in 0.01% DMSO carrier is added with the induction medium for Days 0 to 2, 2 to 4, and 4 to 6 of adipogenesis. Medium is changed every 2 days. Before assay for cell viability, cells are washed with DMEM/10% FBS three times, and 100 μL of DMEM/10% FBS medium is added to each well before treatment with 20 μL MTS assay solution per well. Cells are incubated for 1 hour at 37 °C; then 25 μL of 10% sodium dodecyl sulfate is added to each well. The absorbance is measured at 490 nm in a plate reader to determine the formazan concentration, which is proportional to the number of live cells.

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.
