PPADS tetrasodium salt is a non-selective P2 purinergic antagonist blocking recombinant P2X1, P2X2, P2X3, P2X5 with IC50 of 1-2.6 μM, native P2Y2-like with IC50 of ~ 0.9 mM, and recombinant P2Y4 receptors with IC50 of ~ 15 mM.
| Molecular Weight | 599.3 |
| Formula | C14H10N3Na4O12PS2 |
| CAS Number | 149017-66-3 |
| Solubility (25°C) | Water 6 mg/mL |
| Storage | -20°C, dry, sealed |
| Species | Mouse | Rat | Rabbit | Guinea pig | Hamster | Dog |
| Weight (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| 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.
