1-NM-PP1 (CAT: I002695), also known as PP1 Analog II, is a cell-permeable compound with significant implications in kinase inhibition. It serves as a potent and selective inhibitor of mutant kinases compared to their wild-type counterparts. Notably, 1-NM-PP1 effectively targets and inhibits the activity of mutant kinases, such as v-Src (IC50 = 28 μM) and v-Src-as1 I338G (IC50 = 4.2 nM). This inhibitor’s selectivity for mutant kinases over wild-type forms underscores its potential importance in cancer research and personalized medicine, where targeting specific kinase mutations can offer innovative therapeutic strategies for disease treatment and intervention.
