Biological Activity

CD437 is a retinoic acid receptor (RAR)γ-selective agonist, γ-selective retinoid; potent inducer of apoptosis. It displays RARγ-dependent and -independent effects on differentiation and apoptosis. CD437 reduces the numbers of H460, SK-MES-1, A549, and H292 cells with 50% inhibitory values of approximately 0.5, 0.4, 3, and 0.85 μM, respectively. Treatment for 72 h with CD437 causes a strong dose-dependent growth inhibition in all melanoma cell lines. At a concentration of 5 μM CD437, only about 5 to 25% of the cells remain viable after 3 d. The concentrations of CD437 required for 50% growth inhibition (IC50) range from 10 μM for MeWo to 0.1 μM for SK-Mel-23 showing the highest sensitivity.

In vivo, tumors in CD437-treated mice stop growing, an effect that becomes already statistically significant (P<0.01) at day 13, 3 d after first administration of CD437, and is maintained for more than 3 wk after discontinuation of treatment. Further histologic analysis demonstrates marked c-fos mRNA levels at the tumor-stroma edge in CD437-treated tumors.

Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km

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.
