UM-259 is a STING inhibitor, with an EC50 of 1.50 μM in THP1-Dual cells expressing wild-type STING. UM-259 blocks STING oligomerization and inhibits diABZI-induced phosphorylation of TBK1 and IRF3, thereby suppressing the transcription of IFNβ and IL6 and reducing IFNβ secretion. UM-259 can be used for the study of STING-dependent inflammatory and neurological diseases.

Description

UM-259 is a STING inhibitor, with an EC50 of 1.50 μM in THP1-Dual cells expressing wild-type STING. UM-259 blocks STING oligomerization and inhibits diABZI-induced phosphorylation of TBK1 and IRF3, thereby suppressing the transcription of IFNβ and IL6 and reducing IFNβ secretion. UM-259 can be used for the study of STING-dependent inflammatory and neurological diseases[1].

In Vitro

UM-259 (0.2-5 μM, pretreated for 1 h) exerts potent inhibitory activity on diABZI-induced IFNβ and IL6 gene transcription in iBMDMs[1].
UM-259 (2.5 μM, pretreated for 1 h) displays potent activity in blocking STING-dependent IFNβ secretion in primary human CD14+ monocytes[1].
UM-259 (5 μM, pretreated for 1 h) shows potent inhibitory activity on diABZI-induced phosphorylation of TBK1 and IRF3and exhibits potent activity in inhibiting STING oligomerization in WT BMDMs, effectively blocking STING downstream signal transduction[1].

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

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
