摘要: 特发性肺纤维化(IPF)是一种进行性并最终致命的慢性间质性肺病,其特征是肺功能进行性下降,且目前治疗选择有限。cAMP是最重要的第二信使之一,在松弛气道平滑肌细胞和减少炎症方面起着关键作用。磷酸二酯酶(PDE)是一种酶超家族,PDE4酶在 11种 PDE超家族酶中占主导地位,并具有4种同工型 ——PDE4A、 PDE4B、PDE4C和 PDE4D,可选择性地水解 cAMP,而 PDE4抑制剂通过阻止 cAMP分解来提高 cAMP水平,从而发挥抗炎、抗重塑作用,为治疗 IPF提供了一个有吸引力的药物靶点。本综述总结了肺纤维化与 PKE4相互关联的知识,以及有关 PDE4抑制剂的新出现的临床前研究和临床试验。

Abstract:

Idiopathic pulmonary fibrosis (IPF) is a progressive and ultimately fatal chronic interstitial lung disease characterized by a progressive decline in lung function, and current treatment options are limited. cAMP is one of the most important second messengers and plays a key role in relaxing airway smooth muscle cells and reducing inflammation. Phosphodiesterase (PDE) is a superfamily of enzymes, and PDE4 enzymes dominate 11 PDE super-family enzymes, available in four isoforms-PDE4A, PDE4B, PDE4C and PDE4D, which selectively decompose cAMP, while PDE4 inhibitors increase cAMP levels by preventing cAMP from breaking down, thereby exerting anti-inflammatory, anti-remodeling effects and providing an attractive drug target for the treatment of IPF. This review summarizes knowledge about the association of pulmonary fibrosis with PKE4, as well as emerging preclin-ical studies and clinical trials regarding PDE4 inhibitors.

Key words: pulmonary fibrosis, cAMP, PDE4, PDE4 inhibitors
