UM-200

UM-200 is a covalent STING inhibitor with an EC₅₀ of 1.10 μM. UM-200 covalently modifies the cysteine residues C292 or C309 of STING, thereby blocking its oligomerization and downstream signal transduction. UM-200 inhibits STING-dependent phosphorylation of TBK1 and IRF3. UM-200 inhibits the STING signaling pathway in mouse models. UM-200 can be used for research on STING-driven inflammatory and autoimmune diseases.

体外実験

UM-200 (0.08-40 μM; 1 h pretreatment, 24 h stimulation) potently inhibits STING signaling in THP1-Dual KI-hSTING-R232 cells with an EC₅₀ of 1.10 μM^[1].
UM-200 (1 h pretreatment, 2 h stimulation) inhibits diABZI-induced IFNβ and IL6 gene transcription in immortalized bone marrow-derived macrophages^[1].
UM-200 (1 h pretreatment, 24 h stimulation) inhibits diABZI-induced IFNβ secretion in immortalized bone marrow-derived macrophages^[1].
UM-200 (2.5 μM; 1 h pretreatment, 16 h stimulation) inhibits diABZI-induced IFNβ secretion in primary human CD14+ monocytes when dosed at 2.5 μM^[1].
UM-200 (1 μM; 1 h pretreatment, 30-120 min stimulation) inhibits diABZI-induced phosphorylation of TBK1 and IRF3, and blocks STING oligomerization in wild-type bone marrow-derived macrophages when dosed at 1 μM^[1].
UM-200 (1 μM; up to 45 min) exhibits improved metabolic stability in human liver microsomes with a half-life of 77 min^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
