Figure 2From: Cystathionine-β-Synthase Inhibition for Colon Cancer: Enhancement of the Efficacy of Aminooxyacetic Acid via the Prodrug ApproachEffect of AOAA and YD0171 on the H2S-synthesizing activity of human recombinant full-length CBS enzyme. AOAA concentration dependently inhibited H2S production (detected by the AzMC method) with an IC50 of ∼2 µmol/L, while YD0171 was a substantially weaker direct inhibitor of recombinant CBS activity (IC50: ∼300 µmol/L). Data shown as mean ± SEM; n = 3.Back to article page
