Disitertide (P144) diammonium is a polypeptide inhibitor of transforming growth factor TGFβ1, specifically blocking its interaction with the receptor. Disitertide diammonium was also an inhibitor of PI3K and an inducer of apoptosis.

| CAS Number | 272105-42-7 (free base) |
| Solubility (25°C) | DMSO 10 mg/mL Water 5 mg/mL (ultrasonic and adjust pH with NH3·H2O) |

| 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.
