Biochem/physiol Actions

MRIA9 is an ATP site-targeting, dual salt-inducible kinase (SIK1/2/3 IC50 = 55/48/22 nM; SIK2/3 IC50 = 180/127 nM by cell-based NanoBRET) & p21-activated kinase (PAK2/3 IC50 = 41/140 nM; PAK1 IC50 = 580 nM) inhibitor with excellent selectivity over other kinases. MRIA9 sensitizes ovarian cancer cells to mitotic agent paclitaxel (Pac) treatment in SKOV3 cultures (1 nM Pac plus 0.5-5 µM MRIA9) and HeLa spheroids (2 nM Pac plus 5 µM MRIA9).

Salt-inducible kinases (SIKs) are key metabolic regulators. The imbalance in SIK function is associated with the development of diverse cancers, including breast, gastric, and ovarian cancers. Chemical tools to clarify the roles of SIK in different diseases are, however, sparse
