体外研究
(In Vitro)

diABZI STING agonist-1 is a selective stimulator of interferon genes (STING) receptor agonist, with EC50s of 130, 186 nM for human and mouse, respectively. At a concentration of 1 μM, diABZI STING agonist-1 (compound 3) demonstrates high selectivity against more than 350 kinases tested[1].

体内研究
(In Vivo)

diABZI STING agonist-1 trihydrochloride (subcutaneous injection; 2.5 mg/kg) induces STING-dependent activation of type-I interferon and pro-inflammatory cytokines in vivo[1].
diABZI STING agonist-1 trihydrochloride (intravenous injection; 3 mg/kg) exhibits systemic exposure with a half-life of 1.4 h and achieves systemic concentrations greater than the half-maximal effective concentration (EC50) for mouse STING (200 ng/ml)[1].
diABZI STING agonist-1 trihydrochloride (intravenous injection; 1.5 mg/kg; days 1, 4 and 8; 43 days) results in significant tumour growth inhibition and significantly improves survival (P < 0.001) with 8 out of 10 mice remaining tumor free at the end of the study on day 43[1].
