Description

General description

A cell-permeable imidazolium compound that inhibits the activity of bacterial histidine kinases (EnvZ, PhoQ, BvgS, and EvgS) and eukaryotic eEF-2 (elongation factor 2) kinase/CaMKIII (IC₅₀ = 60 nM), while exhibiting much lower potency against PKC, PKA, and CaMKII (IC₅₀ = 7.5, 80, and >100 µM, respectively). NIH125 is a known P-gp substrate, which limits its in vivo efficacy as an anticancer and antimicrobial agent.

Biochem/physiol Actions

Primary Target
