Description
Compstatin binds to and inhibits complement activation with IC50 of 12 μM.
Targets
| complement component C3 [4] |
| 12 μM |
In vitro
Compstatin binds to native C3 and inhibits its cleavage by C3 convertase. Binding of Compstatin to native C3 is a multistep reaction that is preferred over its binding to the C3 fragments C3b and C3c. N-acetylation of Compstatin provides stability against enzymatic degradation.Compstatin features a high selectivity for human and primate C3. While binding to C3 from baboons and other primates shows comparable interaction profiles as its human counterpart, no binding is detected for C3 from lower mammalian species such as mice, rats, guinea pigs, rabbits, or pigs.
