  4. SRI-42127

SRI-42127 is a HuR translocation inhibitor. HuR is an RNA regulator that binds to AREs, and HuR translocations promote the production of inflammatory cytokines in glial cells. However, SRI-42127 can destroy mRNA stability and inhibit gene promoter activation. SRI-42127 also inhibits microglial cell activation and attenuates recruitment/chemotaxis of neutrophils and monocytes.

Description

SRI-42127 is a HuR translocation inhibitor. HuR is an RNA regulator that binds to AREs, and HuR translocations promote the production of inflammatory cytokines in glial cells. However, SRI-42127 can destroy mRNA stability and inhibit gene promoter activation. SRI-42127 also inhibits microglial cell activation and attenuates recruitment/chemotaxis of neutrophils and monocytes[1].

IC50 & Target

HuR[1]
In Vitro

SRI-42127 (0.05-1 μM; 24 h) blocks HuR cytoplasmic translocation stimulated by LPS (1 μg/mL) in primary microglia[1].
SRI-42127 (0.05-1 μM; 24 h) suppresses inflammatory cytokine and chemokine mRNA in activated Primary microglia cells (PMG)[1].
SRI-42127 (0.5 μM and 1 μM; 24 h) blocks glial-produced chemoattraction/migration signals for neutrophils and monocytes[1].

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.
