PRMT5-IN-11 demonstrates potent structure-dependent inhibition against the protein methyltransferase PRMT5:MEP50 complex at submicromolar concentrations.
PRMT5-IN-19 (Compound 41) is a potent orally active PRMT5 inhibitor, exhibiting selectivity towards the SAM-binding pocket of PRMT5 with IC50 values of 23.9 nM (radioactive biochemical assay) and 47 nM (AlphaLISA assay). It effectively blocks methyltransferase activity and demonstrates high specificity against other PRMTs and PKMTs. PRMT5-IN-19 exerts anti-proliferative effects through the induction of apoptosis and holds potential in cancer-related research [1].
