Description
OverviewA 5-fluorotryptamine derivative that inhibits myeloperoxidase/MPO activity (IC50 = 18 nM) via direct affinity interaction with enzyme active site heme pyrrole ring D, while exhibiting much reduced affinity toward serotonin reuptake transporter/SERT (Ki = 631 nM). Kinetic studies reveal that the inhibitor acts as a good one-electron donor for the intermediate Compound I "Fe(IV)=O...Por•+", facilitating the formation of Compound II (Fe(IV)-OH...Por) and thereby preventing the reduction of Compound I directly to the resting state "Fe(IV)...Por" via the "halogenation cycle", while, on the other hand, behaves as a poor electron donor for Compound II, thereby preventing the completion of the "peroxidase cycle" by stalling the further reduction of Compound II to the resting state.

Please note that the molecular weight for this compound is batch-specific due to variable water content.

Revision16-August-2013 JSW
Synonyms4-(5-Fluoro-1H-indol-3-yl)butanamide, MPO Inhibitor II
DescriptionA 5-fluorotryptamine derivative that inhibitis the MPO-catalyzed Cl-/chloride-to-OCl-/hypochlorite oxidation in the presence of H2O2 (IC50 = 18 nM by taurine/2-aminoethan-sulfonic acid chlorination assay) as well as MPO-mediated LDL ApoB-100 (ApoB100; apolipoprotein B-100) oxidation (IC50 = 18 nM by ELISA) via direct affinity binding at the myeloperoxidase active site through ϖ-ϖ interaction between its indole and the the enzyme's heme pyrrole ring D, while exhibiting much reduced affinity toward serotonin reuptake transporter/SERT (Ki = 631 nM). Kinetic studies reveal that the inhibitor acts as a good one-electron donor for the intermediate Compound I "Fe(IV)=O...Por•+", facilitating the formation (k3 = 1,6 x 107 M-1 s-1) of Compound II (Fe(IV)-OH...Por) and thereby preventing the reduction of Compound I directly to the resting state "Fe(IV)...Por" via the "halogenation cycle", while, on the other hand, behaves as a poor electron donor for Compound II, thereby preventing the completion of the "peroxidase cycle" by stalling the further reduction of Compound II to the resting state (k4 = 92 M-1 s-1). Toxicology study using Wistar Han male rats reports no signs of adverse effects post single 10 mg/kg i.p. dosage, while signs of adverse effects are observed within the 24 h, but not after, post a higher i.p. dosage at 100 mg/kg.
