MAPK-IN-3

MAPK-IN-3 (Compound 4a) is an anti-proliferative agent that shows particularly strong inhibitory effects on KYSE 30, HCT 116, and HGC 27, with IC₅₀ values of 0.57 μM, 3.27 μM, and 2.28 μM, respectively. MAPK-IN-3 blocks the cell cycle via a p53-dependent mechanism and induces cell apoptosis through a p53-independent mechanism. MAPK-IN-3 downregulates the expression of cell cycle-related proteins like Cyclin D1 and cyclin B1, upregulates pro-apoptotic proteins such as cleaved PARP, cleaved caspase-7, and cleaved caspase-9, and reduces the expression of anti-apoptotic proteins like Bcl-2. Additionally, MAPK-IN-3 increases the intracellular level of ROS in KYSE 30 cells and upregulates the expression of members of the MAPK signaling pathway associated with ROS, such as p-ERK, p-p38 and p-JNK.
