CInQ-03
CInQ-03 is an allosteric inhibitor of MEK1/2, with IC50 values of 5 μM and 10 μM against MEK1 and MEK2, respectively. CInQ-03 inhibits the kinase activity of MEK1/2 and reduces the phosphorylation levels of downstream ERK1/2 and RSK. CInQ-03 suppresses both anchorage-dependent and anchorage-independent growth of colon cancer cells, the activity of AP-1 reporter gene in colon cancer cells, as well as EGF-induced growth, transformation and AP-1 reporter gene activity in HaCaT keratinocytes. CInQ-03 can be used in studies related to colon cancer.

CInQ-03 (5-10 μM; 2 h pre-incubation, then 12-24 h EGF stimulation) suppresses EGF-induced AP-1 promoter activity in HaCaT human keratinocytes in vitro in a dose-dependent manner, with 10 μM causing stronger inhibition than 5 μM for both 12 h 10 ng/mL EGF and 24 h 20 ng/mL EGF stimulation[1].
CInQ-03 reduces ERK phosphorylation in cultured cells, confirming its target engagement in a cellular context[2].
CInQ-03 inhibits MEK1 (IC50 = 5 μM) and MEK2 (IC50 = 10 μM) kinases in vitro, with a binding mode consistent with established MEK inhibitors[3].

Result:Suppressed HCT116 tumor growth by over 70% relative to vehicle-treated controls (P < 0.05).
Markedly decreased Ki-67 expression in tumor tissues, while Ki-67 expression in skin tissues was similar to vehicle-treated controls.
Strongly suppressed phosphorylated ERKs and phosphorylated RSK in tumor tissues.
Showed no overt signs of toxicity or significant body weight loss compared to the vehicle group.
