  Novel Class of Benzoic Acid Ester Derivatives as Potent PDE4 Inhibitors for Inhaled Administration in the Treatment of Respiratory Diseases

  摘要：

  The first steps in the selection process of a new anti-inflammatory drug for the inhaled treatment of asthma and chronic obstructive pulmonary disease are herein described. A series of novel ester derivatives of 1-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-2-(3,5-di-chloropyriclin-4-yl) ethanol have been synthesized and evaluated for inhibitory activity toward cAMP-specific phosphodiesterase-4 (PDE4). In particular, esters of variously substituted benzoic acids were extensively explored, and structural modification of the alcoholic and benzoic moieties were performed to maximize the inhibitory potency. Several compounds with high activity in cell-free and cell-based assays were obtained. Through the evaluation of opportune in vitro ADME properties, a potential candidate suitable for inhaled administration in respiratory diseases was identified and tested in an in vivo model of pulmonary inflammation, proving its efficacy.

  identification of novel classes of potent PDE4 inhibitors suitable for pulmonary administration. Starting from a previous series of benzoic acid esters, we explored the chemical space in the solvent-exposed region of the enzyme catalytic binding pocket. Extensive structural modifications led to the discovery of a number of heterocycloalkyl esters as potent in vitro PDE4 inhibitors. (S*,S**)-18e and

  磷酸二酯酶4（PDE4）是一种参与炎症性疾病发病机理的关键cAMP代谢酶，其药理学抑制作用已显示出可在慢性阻塞性肺疾病（COPD）中发挥治疗作用。在本文中，我们描述了一种旨在发现适用于肺部给药的新型新型强效PDE4抑制剂的药物开发程序。从先前的苯甲酸酯系列开始，我们探索了酶催化结合口袋中溶剂暴露区域的化学空间。广泛的结构修饰导致发现许多杂环烷基酯作为有效的体外PDE4抑制剂。（S *，S **）- 18e和（S *，特别地，S **）- 22e在实验动物模型中表现出最佳的体外ADME和药代动力学性质，并剂量依赖性地抵消了急性肺嗜酸性粒细胞增多。最佳的生物学特性以及出色的固态特性表明，这两种化合物都有可能成为治疗呼吸道炎性疾病的有效局部药物。
