Characterization of the synthetic cathinone-binding affinity of SCA2.1 using ITC. Top panels present raw data showing the heat generated from each titration of (A) (−)-MDPV, (B) (+)-MDPV and (C) (±)-MDPV to SCA2.1, while bottom panels show the integrated heat of each titration after correcting for dilution heat of the titrant. ITC data obtained with (−)-MDPV and (+)-MDPV were fitted using a single-site model, and ITC data obtained with (±)-MDPV were fitted with a modified two-site binding model. All binding parameters are shown in Supplementary Table S4.
