Clear solution	5%DMSO 1 Corn oil	2.3mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 46 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O	2.3mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 46 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	Alantolactone, a naturally occurring eudesmane-type sesquiterpene lactone (SL), could induce activin/SMAD3 signaling and disrupt Cripto-1/activin receptor type II A interaction.
in vitro	Alantolactone selectively suppresses STAT3 activation and exhibits potent anticancer activity in MDA-MB-231 cells. Alantolactone effectively suppressed both constitutive and inducible STAT3 activation at tyrosine 705. It decreased STAT3 translocation to the nucleus, its DNA-binding, and STAT3 target gene expression. Alantolactone significantly inhibits STAT3 activation with a marginal effect on MAPKs and on NF-κB transcription; however, this effect is not mediated by inhibiting STAT3 upstream kinases. SHP-1, SHP-2, and PTEN, which are protein tyrosine phosphatases (PTPs) were not affected by alantolactone. Alantolactone treatment resulted in the inhibition of migration, invasion, adhesion, and colony formation^[1]. Alantolactone could induce activin signaling and activin target gene expression. Alantolactone activated the activin signaling pathway in a cancer cell line. It could promote SMAD2/3 nuclear translocation in a very short time^[3].
in vivo	In vivo administration of alantolactone inhibited the growth of human breast xenograft tumors^[1]. Alantolactone exerts no toxic effect on liver and kidneys in vivo, The drug was well tolerated by mice and no mortality or any sign of pharmacotoxicity was found at a dose of 100 mg/kg during all the experimental periods. Alantolactone can cross blood-brain barrier^[2].

細胞アッセイ	細胞株	MDA-MB-231 and MCF-7 cells
	濃度	15 μM
	反応時間	24 h
	実験の流れ	Cell viability was evaluated using MTT assay. The cells were seeded into 96-well plates and maintained at 37 °C for 24 h. The cells were treated with alantolactone for 24 h. The MTT solution (0.5 mg/mL) was added to each well, and the cells were incubated for another 3 h. The MTT formazan crystals were dissolved in DMSO. The results were obtained by measuring the absorbance at a wavelength of 540 nm using a microplate reader.
