Compstatinis is a 13-residue cyclic peptide, binds to complement component C3 and inhibits complement activation with IC50 of 12 μM. Compstatin features a high selectivity for human and primate C3. Compstatin completely inhibits in vivo heparin/protamine-induced complement activation without adverse effects on heart rate or systemic arterial, central venous, and pulmonary arterial pressures. Compstatin exhibits exclusive specificity for primate C3s and does not bind either to C3s from lower mammalian species or to two structural homologs of C3, human C4 and C5.

| 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.
