  • 产品名称:
    MSA-2
  • 别名:
    4-(5,6-Dimethoxybenzo[b]thiophen-2-yl)-4-oxobutanoic acid
  • 产品描述:
    MSA-2 is a new orally available (cell permeable) non-nucleotide STING (STimulator of INterferon Genes) agonist, with EC50s of 8.3 and 24µM for human STING isoforms WT and HAQ. Activation of the STING protein by its natural ligand, cyclic guanosine monophosphate-adenosine monophosphate (cGAMP, a cytosolic double-stranded DNA sensor), triggers signaling responses, inducing the release of type I interferons and other proinflammatory cytokines. STING-controlled interferon production is involved in antiviral defense as well as antitumor immunity. Pharmacological activation of STING is considered a promising therapeutic strategy for cancer. MSA-2 highly induces secretion in vitro of IFN-beta from THP-1 cells and mouse macrophages at concentration of 10-50µM. It shows in vivo antitumor activity in a MC38 mouse model of colon carcinoma in a dose-dependent manner, stimulating IFN-beta secretion in tumors, inducing tumor regression with durable antitumor immunity when administered intratumorally (450µg), subcutaneously (50mg/kg) or orally (50mg/kg), and synergizes with anti-PD-1 therapy. MSA-2 is a small molecule monomer that undergoes reversible, noncovalent dimerization in solution to become a pharmacologically active ligand. MSA-2 monomers cannot bind STING, whereas the noncovalent MSA-2 dimers bind STING with nanomolar affinity. MSA-2, a weak acid, exhibits substantially higher cellular potency in an acidified tumor microenvironment (versus normal tissue), owing to increased cellular entry and retention combined with its inherent mode of interaction with STING.
