Sodium Etidronate (Didronel, EHDP, Etidronic acid) is a non-aminobisphosphonate that exhibits protein tyrosine phosphatase (PTP) inhibitory activity.
Molecular Weight | 249.99 |
Formula | C2H6Na2O7P2 |
CAS Number | 7414-83-7 |
Solubility (25°C) | Water 50 mg/mL |
Storage |
Powder -20°C 3 years ; 4°C 2 years In solvent -80°C 6 months ; -20°C 1 month |
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.
