  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.

  This invention is related to novel aminoalkyl- and amidoalkyl-benzopyran derivatives of the following general formula (I) wherein: the group is a substituent in position 6 or 7 wherein: R is an aromatic mono- or bi-cyclic carbocyclic ring or a mono- or bi-cyclic heterocyclic ring radical, said rings being optionally substituted by one or two substituents selected from (C 1 -C 5 ) straight or branched alkyl, (C 1 -C 5 ) straight or branched alkoxy, hydroxy, halogen and trifluoromethyl; m is zero or an integer from 1 to 3; n, p, R 1 and R 2 are as herein indicated and R 3 and R 4 are both hydrogen or taken together represent an oxygen atom, and the pharmaceutically acceptable salts thereof. The compounds that are active as selective and reversible MAO-B inhibitors in vitro and in vivo, are useful as medicaments for the prevention and the treatment of CNS degenerative disorders.

  本发明涉及以下通式（I）的新型氨基烷基和酰胺烷基苯并吡喃衍生物： 其中：基团是6或7位的取代基，其中：R是芳香单环或双环碳环或单环或双环杂环基团，所述环可以选择地由一或两个取代基取代，所述取代基选择自（C1-C5）直链或支链烷基，（C1-C5）直链或支链烷氧基，羟基，卤素和三氟甲基；m为零或1至3的整数；n、p、R1和R2如本文所示，而R3和R4均为氢或一起代表氧原子，以及其药学上可接受的盐。 这些化合物在体外和体内作为选择性和可逆的MAO-B抑制剂具有活性，可用作预防和治疗中枢神经系统退行性疾病的药物。
