MSA-2 dimer is an oral non-nucleotide STING agonist with nanomolar affinity (Kd = 145 μM). It binds to STING as a non-covalent dimer and has long-term antitumor and immunogenic activity. MSA-2 dimer has higher permeability than cyclic dinucleotide, making it a promising candidate for cancer immunotherapy.
