Ro 51 is a potent, dual P2X3 and P2X2/3 antagonist (IC50 values are 2 and 5 nM for rP2X3 and hP2X2/3 respectively). Selective for P2X3 and P2X2/3 over other P2X receptors (IC50 values are > 10 μM for P2X1, P2X2, P2X4, P2X5, and P2X7). Cell permeable.

| Body Surface Area (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km factor | 3 | 6 | 12 | 8 | 5 | 20 |
| 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.
