MSA-2 生物活性

描述 MSA-2, a powerful orally available non-nucleotide STING agonist, binds to STING as a noncovalent dimer with nanomolar affinity. It displays EC50 values of 8.3 and 24 μM for human STING isoforms WT and HAQ, respectively. MSA-2 promotes interferon-β secretion in tumors, leads to tumor regression with lasting antitumor immunity, and enhances the effectiveness of anti-PD-1 therapy in syngeneic mouse tumor models[1][2].
体内研究

MSA-2, administered either orally (PO) or subcutaneously (SC), achieves similar levels of exposure in both tumor and plasma. Additionally, MSA-2 demonstrates dose-dependent antitumor effects whether delivered intratumorally (IT), subcutaneously (SC), or orally (PO). Dosing regimens have been established that result in complete tumor regression in 80 to 100% of the animals treated[1].

MSA-2 (PO: 60 mg/kg or SC: 50 mg/kg; single dose) effectively inhibits tumor growth and significantly increases levels of IFN-β, interleukin-6 (IL-6), and TNF-α within the tumor[1].
