117570-53-3 Usage
Description
5,6-Dimethylxantheonone-4-acetic acid (DMXAA) is a flavone acetic acid derivative that acts as a vascular disrupting agent (VDA). It is a STING (Stimulator of Interferon Genes) agonist selective for mouse STING. DMXAA has the ability to damage tumor vasculature and stimulate an anti-tumor immune response, leading to hemorrhagic necrosis.
Uses
Used in Anticancer Applications:
5,6-Dimethylxantheonone-4-acetic acid is used as an anticancer agent for inducing tumor regression and complete rejection in mouse xenografts. It works by disrupting tumor vasculature, releasing chemokines, and triggering the recruitment of immune cells. Additionally, DMXAA induces the expression of IFN-β, resulting in a significant expansion of leukemia-specific T cells and extending survival in acute myeloid leukemia models.
Used in Immune Response Stimulation:
5,6-Dimethylxantheonone-4-acetic acid is used as an immune response stimulator for activating the immune adaptor protein STING in mice. This activation leads to a cascade of cellular events that contribute to the anti-tumor immune response and tumor regression.
Used in Drug Development:
5,6-Dimethylxantheonone-4-acetic acid is used as a compound in drug development for its potential applications in cancer treatment. Its vascular-disrupting activity and immune-stimulating properties make it a promising candidate for further research and development in the pharmaceutical industry.
Biochem/physiol Actions
DMXAA is an apoptosis inducer; anti-vascular.

Check Digit Verification of cas no
The CAS Registry Mumber 117570-53-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,5,7 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 117570-53:
(8*1)+(7*1)+(6*7)+(5*5)+(4*7)+(3*0)+(2*5)+(1*3)=123
123 % 10 = 3
So 117570-53-3 is a valid CAS Registry Number.
