Benzazulenones have higher IC50 with less change over time as compared to OphA. Change of effective CaM-binding affinity over time of OphA and formyl aminobenzazulenones (A) and aminobenzazulenones (B) as measured in the fluorescence polarization assay using F-PMCA peptide as the fluorescent probe. Data represent mean values ± SD, n = 2. Binding curves are plotted in Supplementary Figures 2A,B. Derived rate analysis plots are in Supplementary Figures 2G,H.
