Biological Activity

NSC 66811 is a potent MDM2 inhibitor with Ki value of 120 nM, which disrupts MDM2-p53 interaction and activates p53 function. NSC-66811 induces p21, p53 and MDM2 accumulation in human colon cancer cells in vitro. NSC 66811 is more potent than the natural p53 peptide to bind with MDM2.

Source Acta Pharmacol Sin (2015). Figure 2. NSC 66811
Method PCR
Cell Lines HepG2 cells
Concentrations 5 and 25 μmol/L
Incubation Time 24 h
Results The p53 mRNA levels were up-regulated by NSC 66811 (Figure 2F) without affecting the CYP expression. NSC 66811 decreased the metabolism of DEM (Figure 2G) and TEST (Figure 2H) in a dose-dependent manner.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
