p53-MDM2-IN-6, an LSM-83177 hydrazone analog, acts as an efficacious p53-MDM2 inhibitor with an IC50 of 11.08 µg/mL. This compound inhibits the p53-MDM2 interaction leading to an increase in p-53 levels while concurrently decreasing GST enzyme expression. It halts the cell cycle at the S phase and induces early and late apoptosis (Apoptosis), exhibiting antiproliferative activity against the HT29 cell line with an IC50 of 10.44 µg/mL. p53-MDM2-IN-6 holds promise for research in colorectal cancer.
