Product Introduction

Bioactivity

Description	Chrexanthomycin A is a marine natural product with notable biological activity and oral bioavailability. It exhibits binding affinities to DNA (G4C2)4G4 and RNA (G4C2)2G4 with Kd values of 2.2 mM and 3.0 mM, respectively. Chrexanthomycin A can be utilized for research on neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS).
In vitro	Chrexanthomycin A (Compounds cA) effectively binds to DNA (G4C2) 4 G4 and RNA (G4C2) 2 G4, with dissociation constants (K d) of 2.2 mM and 3.0 mM, respectively. It demonstrates high cell permeability and low cytotoxicity. At 1.61 μM, Chrexanthomycin A rescues G4C2 EHR-related cellular pathologies. It selectively interacts with G4C2 G4 structures in both DNA and RNA. In a concentration range of 0-100 μM, it significantly reduces cell death induced by G4C2 EHR, diminishes RNA foci in (G4C2)29-expressing Neuro2a cells, and effectively reduces reactive oxygen species (ROS) in HT22 cells. In a Cell Cytotoxicity Assay on HEK293T cells at concentrations of 0.16, 1.61, and 16.13 μM for 24 hours, it showed no cytotoxicity up to 10 μg/mL.
In vivo	Chrexanthomycin A (Compounds cA) at a concentration of 100 μM, administered through feeding, effectively mitigates eye degeneration and enhances locomotor performance in subjects expressing (G4C2)29.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments

and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent

10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO TargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO TargetMol | reagent stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH₂O TargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.

This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.

All co-solvents required for this protocol, includingDMSO, PEG300/PEG400, Tween 80, SBE-β-CD, and Corn oil, are available for purchase on the TargetMol website.
