I-191

I-191 is an antagonist of ERK1 used in studies of MAPK / ERK Signaling and GPCR Signaling. In practice, this places the compound in experiments that measure mitogenic kinase cascades, proliferation control, and differentiation-linked signaling and receptor-driven second-messenger signaling and desensitization dynamics in cancer and cell signaling models.

By blocking ERK1, I-191 can be used to examine mitogenic kinase cascades, proliferation control, and differentiation-linked signaling and receptor-driven second-messenger signaling and desensitization dynamics. The kinase annotation adds relevance to biochemical kinase assays, phospho-signaling studies, and selectivity profiling, together with downstream-response mapping in the same experimental setting. In cancer and cell signaling models, these readouts can be combined with viability, reporter, localization, biochemical conversion, or morphology endpoints to refine experimental interpretation.

Research Applications

• Target-focused assays involving ERK1
• Pathway perturbation studies connected to MAPK / ERK Signaling and GPCR Signaling
• Receptor-blockade and ligand-competition studies
• Biochemical kinase assays, phospho-signaling studies, and selectivity profiling

Overall, I-191 is appropriate when a defined chemical perturbant is needed to connect ERK1 with measurable biochemical, transcriptional, electrophysiological, imaging, or phenotypic readouts in cancer and cell signaling models. This profile is suited to mechanistic follow-up, comparative profiling, and assay optimization under defined exposure conditions.
