UM-259

• 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].
