TfR-T12 is a transferrin receptor (TfR) binding peptide that can penetrate the blood-brain barrier (BBB), exhibiting a high binding affinity within the nanomolar (nM) range.
Hydroxy-PEG12-t-butyl ester is a PEG derivative containing a hydroxyl group and a t-butyl ester. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. Under acidic conditions, the t-butyl protected carbox
Azido-PEG12-t-butyl ester is a PEG derivative containing an azide group and a t-butyl ester. The hydrophilic PEG spacer increases solubility in aqueous media. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole
STING agonist 12b is an agonist of stimulator of interferon genes (STING).1It binds to STING (Kd= 26.4 μM) and induces interferon reporter gene expression in cells expressing human or mouse STING (EC50s = 7.45 and 10.23 μM, respectively). STING agonist 12b (40 μM) induces expression of TNF-a, IL-6, IP-10, and IL-1b in THP-1 cells. 1.Hou, S., Lan, X.-j., Li, W., et al.Design, synthesis and biological evaluation of acridone analogues as novel STING receptor agonistsBioorg.
