Background

5-fluoro 203 (5F-203) is an antitumor agent and cytotoxic compound that acts as a potent AhR agonist [1][2][3].

The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor involved in regulating xenobiotic-metabolizing enzymes such as cytochrome P450.

5-fluoro 203 (5F-203) is an antitumor agent that acts as a potent AhR agonist. In MCF-7 breast cancer cell, 5-fluoro 203 inhibited cell growth in part by activating the aryl hydrocarbon receptor (AhR) signaling pathway. 5-fluoro 203 increased protein-DNA complex formation on the NF-kB-responsive element and also increased NF-kB-dependent transcriptional activity [1]. In sensitive MCF-7 cells, 1.0 μM 5F-203 induced CYP1A1 gene expression [2]. In IGROV-1 cells, 5F203 induced enhanced CYP1A1 expression, AhR translocation and ROS formation, accompanied by JNK, ERK and P38 MAPK phosphorylation, DNA damage and cell cycle arres. In cells isolated from ovarian cancer ascites, 5F203 also induced CYP1A1 expression, AhR translocation and ROS formation [3].

In nude mice bearing human tumor xenografts, 5F-203 induced CYP1A1 gene expression, which was correlated with in vivo sensitivity. Therefore, induction of CYP1A1 mRNA in response to 5F-203 treatments may provide a possible surrogate marker for determination of drug-sensitive tumors in patients [2].

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.
