Concentration-response plots for inhibition of human DDAH-1 by 12 (●) and 13 (□). Experiments are done in the presence of competing substrate Nω, Nω-dimethyl-l-arginine (50 µM; 0.53 × the KM value determined using the same assay format) and results are fitted to inhibition parameters for compound 12 (IC50 = 1.4 ± 0.2 mM; Hill = 1.5 ± 0.2) and 13 (IC50 = 2.7 ± 0.5 mM; Hill = 1.0 ± 0.3).
