Gossypetin is a hexahydroxylated flavonoid and is a potent mitogen-activated protein kinase kinase (MKK)3 and MKK6 inhibitor with strongly attenuates the MKK3/6-p38 signaling pathway, has various pharmacological activities, including antioxidant, antibacterial and anticancer activities[1].
Gossypetin (20-60 μM; 48 hours; KYSE30, KYSE450 and KYSE510 cells) treatment significantly inhibits anchorage-dependent esophageal cancer cell growth in dose dependent manner. Gossypetin strongly suppresses anchorage-independent cell growth in esophageal cancer cells[1]. Gossypetin (60 μM; 3 hours; KYSE30 and KYSE410 cells) treatment strongly inhibits p38 activity in a dose-dependent manner and confirms that Gossypetin directly suppresses MKK3 or MKK6 activity[1].Gossypetin (20-40 μM; 48 hours; KYSE450 and KYSE510 cells) treatment reduces S phase and induces G2 phase cell cycle arrest in a dose-dependent manner[1].Gossypetin (20-40 μM; 72 hours; esophageal cancer cells) treatment induces intrinsic apoptosis of esophageal cancer cells[1]. Cell Proliferation Assay[1] Cell Line: KYSE30, KYSE450 and KYSE510 cells
Gossypetin (100 mg/kg; oral administration; 5 times per week; for 21 days; severe combined immunodeficiency (SCID) female mice) treatment significantly decreases the volume of esophageal tumor growth and without significant loss of body weight. The expression of Ki67 is significantly decreased by Gossypetin. There are no obvious morphological differences between tissues from treated or untreated mic. The phosphorylation of p38, the direct downstream protein of MKK3/6 strongly inhibited in the Gossypetin-treated group[1]. Animal Model: Severe combined immunodeficiency (SCID) female mice (6-9 weeks old) injection with esophageal cancer tissue[1]

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.
