Preincubation of the cells with the Na+ ionophore sodium ionophore III not only stimulated caffeate reduction, but completely abolished ATP synthesis. Addition of sodium ionophore III to cells in the steady state of caffeate reduction immediately dissipated the intracellular ATP level. Lactate-sulfate grown cells are insensitive to the Na+ ionophore, ETH2120. Sodium ionophore III ligand is a very effective receptor for the Eu3+ and Am3+ cations and can be considered as a potential extraction agent for nuclear iste treatment.

| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 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 Compound A of 10 mg/kg.
