Puromycin dihydrochloride is a protein synthesis inhibitor. Puromycin 2HCl leads to the premature release of polypeptide chains as polypeptidyl purine derivatives. Analog of the 3' end of aminoacyl-tRNA. Puromycin dihydrochloride Inhibits translation in both in vitro and in vivo systems. Puromycin dihydrochloride inhibits the transport of proteins into the mitochondria in vitro. Puromycin inhibits protein import into mitochondria by interfering with an ATP-dependent step in the import process and that the ATP-dependent component in the reaction is located inside the inner mitochondrial membrane.

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.
