  Discovery of a Novel Class of Potent Coumarin Monoamine Oxidase B Inhibitors: Development and Biopharmacological Profiling of 7-[(3-Chlorobenzyl)oxy]-4-[(methylamino)methyl]-2H-chromen-2-one Methanesulfonate (NW-1772) as a Highly Potent, Selective, Reversible, and Orally Active Monoamine Oxidase B Inhibitor

  摘要：

  In an effort to discover novel selective monoamine oxidase (MAO) B inhibitors with favorable physicochemical and pharmacokinetic profiles, 7-[m-halogeno)benzyloxy]coumarins bearing properly selected polar substituents at position 4 were designed, synthesized, and evaluated as MAO inhibitors. Several compounds with MAO-B inhibitory activity in the nanomolar range and excellent MAO-B selectivity (selectivity index SI > 400) were identified. Structure-affinity relationships and docking simulations provided valuable insights into the enzyme-inhibitor binding interactions at position 4, which has been poorly explored. Furthermore, computational and experimental studies led to the identification and biopharmacological characterization of 7-[(3-chlorobenzyl)oxy]-4-[(methylamino)methyl]-2H-chromen-2-one methanesulfonate 22b (NW-1772) as an in vitro and in vivo potent and selective MAO-B inhibitor, with rapid blood-brain barrier penetration, short-acting and reversible inhibitory activity, slight inhibition of selected cytochrome P450s, and low in vitro toxicity. On the basis of this preliminary preclinical profile, inhibitor 22b might be viewed as a promising clinical candidate for the treatment of neurodegenerative diseases.

  Structures of human monoamine oxidase B (MAO B) in complex with safinamide and two coumarin derivatives, all sharing a common benzyloxy substituent, were determined by X-ray crystallography. These compounds competitively inhibit MAO B with Ki values in the 0.1-0.5 microM range that are 30-700-fold lower than those observed with MAO A. The inhibitors bind noncovalently to MAO B, occupying both the entrance

  The effects on the inhibition potencies of monoamine oxidase isoforms A (MAO-A) and B (MAO-B) depending upon changes in the physicochemical properties (size, shape, H-bonding, lipophilicity, etc.) of substituents at the C4 position of 2H-chromen-2-one derivatives were extensively investigated, and the results significantly added to our knowledge on this class of MAO inhibitors. All the 67 examined compounds showed high MAO-B selectivity, some of them achieving potency in the low nanomolar range. In particular, the 7-metachlorobenzyloxy-4-oxyacetamido-211-chromen-2-one (entry 62) showed single digit nanomolar MAO-B potency (IC50 = 3.1 nM) and high selectivity over the MAO-A isoform (selectivity ratio = 7244). The great variety of the investigated substituents at C4 of the 2H-chromen-2-one nucleus, combined with binding models generated from docking studies carried out on selected compounds, allowed us to shed light on the main molecular requirements for potent and selective MAO-B inhibition, highlighting the dominant role of the steric effects. Interestingly, many of the designed substituents could be metabolically related to each other (e.g., CH3/CH2OH/CHO/COOH; NH2/NHCH3, NHAc), and therefore the results obtained may help in predicting the in vivo activity of some putative metabolites of lead MAO-B inhibitors.
