ChEMBL Inhibition of recombinant human complement factor D after 1 hr B 9 pIC50 1 nM IC50 ACS Med Chem Lett (2012) 3: 781-782 [PMID:24900375]
ChEMBL In Vitro Assay: Recombinant human factor D (expressed in E. coli and purified using standard methods) at 10 nM concentration is incubated with test compound at various concentrations for 1 hour at room temperature in 0.1 M Hepes buffer, pH 7.5, containing 1 mM MgCl2, 1 M NaCl and 0.05% CHAPS. A synthetic substrate Z-Lys-thiobenzyl and 2,4-dinitrobenzenesulfonyl-fluoresceine are added to final concentrations of 200 μM and 25 μM, respectively. The increase in fluorescence is recorded at excitation of 485 nm and emission at 535 nm in a microplate spectrofluorimeter. IC50 values are calculated from percentage of inhibition of complement factor D-activity as a function of test compound concentration. B 9 pIC50 1 nM IC50 US-9085555-B2.
