BI 6901 is a potent, selective CCR10 antagonist (pIC50=9.0). BI 6901 shows high selectivity over other GPCRs, including a number of other chemokine receptors. BI 6901 is efficacious in the murine DNFB model of contact hypersensitivity and can be used for inflammation research[1].
BI-6901 (intraperitoneal injection; 100 mg/kg; bid.) exhibits a dose-dependent anti-inflammatory response against DNFB stimulated ear swelling in sensitized mice. The level of efficacy observed for BI-6901 is similar to that observed with anti-CCL27 antibody in the same model (60-85%)[1].
