Background

Thiazole antibiotic thiostrepton is an inhibitor of Forkhead box M1 (FOXM1), which effectively reduces cancer cell growth through downregulation of FOXM1. FOXM1 is a transcription factors that regulate expression of genes involved in maintenance of genomic stability and cell cycle progression.

In vitro: Thiostrepton inhibits the transcriptional activity and FOXM1 expression, and induces strong apoptosis in human cancer cells of different origin that correlates with suppression of FOXM1, including leukemia, neuroblastoma, liver cancer, melanoma and prostate cancer cells. Thiostrepton binds FOXM1 on the promoter site to inhibit transcriptional activity of FOXM1 through the FOXM1 autoregulation mechanism [1].

In vivo: Thiostrepton suppressed tumor growth in a human breast cancer xenograft model. Treatment with developed micelle-thiostrepton nanoparticles decreased xenograft tumor growth induced by the human MDA-MB-231 breast and HepG2 liver cancer cell lines. These apoptosis activities in drug-treated tumors were correlated with in vivo suppression of oncogenic FOXM1 [1].

Clinical trial: So far, no clinical study has been conducted.

Calculation results:

Working concentration: mg/ml;

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.
3. All of the above co-solvents are available for purchase on the GlpBio website.
