Slow tight binding inhibitors
Webb21 feb. 1997 · The slow onset of inhibition by 1400W showed saturation kinetics with a maximal rate constant of 0.028 s −1 and a binding constant of 2.0 μ M. Inhibition was dependent on the cofactor NADPH. L -Arginine was a competitive inhibitor of 1400W binding with a Ks value of 3.0 μ M. Inhibited enzyme did not recover activity after 2 h.

WebbUncompetitive inhibitors bind to the enzyme–substrate complex at high concentrations of substrate, but do not bind at very low concentrations. This could suggest that the binding site for the inhibitor is available only when the enzyme–substrate complex has been formed. ... Slow, Tight-Binding Inhibitors ... Webb4 maj 1990 · The peptide is a slow, tight-binding inhibitor, specific for factor Xa ( Ki = 0.588 ± 0.054 n M ).

WebbHere we show that a benzamide HDAC inhibitor, a pimelic diphenylamide (106), is a class I HDAC inhibitor, demonstrating no activity against class II HDACs. 106 is a slow, tight-binding inhibitor of HDACs 1, 2, and 3, although inhibition for these enzymes occurs through different mechanisms. Webb15 aug. 2024 · In our previous study, benzamide-based HDAC inhibitor 106 and MS275 shows slow and tight binding to HDAC enzyme, while compound 4 exhibits reversible binding with fast-on/fast-off profile. Therefore, the enzymatic binding profile of bezamide-based inhibitors is not only dependent ZBG, but also rely on the cap and linker.
