How does Alectinib, a kinase inhibitor, achieve high-affinity binding to complement protein C1q?

PARTIALLY ADDRESSED

The abstract reports that Alectinib binds C1q with high affinity, but this is mechanistically unexpected since Alectinib is designed as a kinase inhibitor while C1q is a complement protein. Understanding this binding mechanism could reveal new drug-target interaction principles and inform rational design of complement modulators.
