Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	STING
In vitro	In human PBMCs, compound 3 induces dose-dependent activation of STING and secretion of IFNβ with an EC50^app of 130 nM.
In vivo	Compound 3 activates secretion of IFNβ, IL-6, TNF, and KC/GROα (also known as CXCL1) in wild-type but not Sting^−/− mice. In BALB/c mice administrated 3 mg/kg compound 3 via intravenous injection, compound 3 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). In mice bearing subcutaneous CT-26 tumours, treatment with compound 3 results in significant tumour growth inhibition as measured by tumour volume AUC analysis (P<0.001), and significantly improves survival (P<0.001) with 8 out of 10 mice remaining tumour free at the end of the study on day 43.
