Biological Activity

α-CHCA is a classic monocarboxylate transporters (MCT) inhibitor. In the sensitive U251 cells, CHCA is able to inhibit cell proliferation and induce cell death, having a cytotoxic effect; however, in the less sensitive SW1088 cells, CHCA only inhibits cell proliferation but did not induce cell death. Transport by MCT1, 2, and 4 is competitively inhibited by CHCA whereas transport by MCT3 is insensitive to α-cyano-4-hydroxy-cinnamic acid.

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.
