Isoalantolactone

Catalog No.S3829

For research use only.

Isoalantolactone, one of the major sesquiterpene lactone compounds, is isolated from the roots of Anula helenium and possesses multiple biological activities including antifungal, anthelmintic, antimicrobial, anti-inflammatory, antitrypanosomal activities and antiproliferative effects on several cancer cell lines, such as colon, melanoma, ovary, prostate, lung, and leukemia. Isoalantolactone is an apoptosis inducer, which also acts as an alkylating agent.

Biological Activity

Description Isoalantolactone, one of the major sesquiterpene lactone compounds, is isolated from the roots of Anula helenium and possesses multiple biological activities including antifungal, anthelmintic, antimicrobial, anti-inflammatory, antitrypanosomal activities and antiproliferative effects on several cancer cell lines, such as colon, melanoma, ovary, prostate, lung, and leukemia. Isoalantolactone is an apoptosis inducer, which also acts as an alkylating agent.
In vitro

Isoalantolactone inhibits growth and induces apoptosis in pancreatic cancer cells. Isoalantolactone increases the expression of phosphorylated p38 MAPK, Bax, and cleaved caspase-3 and decreases the expression of Bcl-2 in a dose-dependent manner[1]. Isoalantolactone treatment in HeLa cancer cells exhibits cytotoxicity in a dose-dependent manner with a low IC50 value of 8.15 ± 1.16 μM[2].

In vivo Isoalantolactone does not induce any acute or chronic toxicity in liver and kidneys of CD1 mice at dose of 100 mg/kg body weight[1]. Isoalantolactone is distributed and eliminated rapidly possibly due to its low-polarity characteristic. A large apparent volume of distribution (138.44 ± 54.14 L) suggests that the lactones may accumulate in certain organs with high concentration after intravenous injection[3].

Protocol (from reference)

Cell Research:[1]
  • Cell lines: PANC-1 cells
  • Concentrations: 20 and 40 µM
  • Incubation Time: 24 h
  • Method: PANC-1 cells are treated with 20 and 40 µM isoalantolactone for 24 h. After treatment, cells are harvested, washed with PBS and fixed with 70% ethanol at 4℃ for overnight. After washing twice with PBS, cells are stained with a solution containing 50 μg/mL PI and 100 μg/mL RNase A for 30 min in the dark at room temperature. The DNA contents for cell cycle phase distribution are analyzed by flow cytometry.

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.
