ZT-12-037-01 is a specific and ATP-competitive STK19 inhibitor with IC50s of 23.96 nM and 27.94 nM for STK19 (WT) and STK19 (D89N), respectively. It displays extremely high kinase selectivity using KINOMEscan against a panel of 468 diverse kinases using an in vitro ATP-site competition binding assay at 1 μM.
ZT-12-037-01 treatment efficiently inhibits phosphorylation of NRAS in a dose- and time-dependent manner. Furthermore, with increasing ATP concentrations, the IC50 of ZT-12-037-01 against STK19 accordingly increased, indicating that ZT-12-037-01 is an ATP-competitive inhibitor for STK19. ZT-12-037-01 treatment significantly inhibits mutant NRAS-STK19-driven melanocyte colony formation, proliferation, and tumor formation. Pro-apoptotic effect of ZT-12-037-01 is dramatically enhanced in cells expressing oncogenic NRAS[1].
ZT-12-037-01 is a highly potent STK19 inhibitor with low in vivo toxicity. Its treatment also inhibits growth of SK-MEL-2 xenograft melanoma (with NRASQ61R) in a dose-dependent manner[1].

Pharmacological Targeting of STK19 Inhibits Oncogenic NRAS-Driven Melanomagenesis
Cell 2019 Feb 21;176(5):1113-1127.e16.PMID:30712867DOI:10.1016/j.cell.2019.01.002
Activating mutations in NRAS account for 20%-30% of melanoma, but despite decades of research and in contrast to BRAF, no effective anti-NRAS therapies have been forthcoming. Here, we identify a previously uncharacterized serine/threonine kinase STK19 as a novel NRAS activator. STK19 phosphorylates NRAS to enhance its binding to its downstream effectors and promotes oncogenic NRAS-mediated melanocyte malignant transformation. A recurrent D89N substitution in STK19 whose alterations were identified in 25% of human melanomas represents a gain-of-function mutation that interacts better with NRAS to enhance melanocyte transformation. STK19D89N knockin leads to skin hyperpigmentation and promotes NRASQ61R-driven melanomagenesis in vivo. Finally, we developed ZT-12-037-01 (1a) as a specific STK19-targeted inhibitor and showed that it effectively blocks oncogenic NRAS-driven melanocyte malignant transformation and melanoma growth in vitro and in vivo. Together, our findings provide a new and viable therapeutic strategy for melanomas harboring NRAS mutations.
