摘要
一氧化氮(nitricoxide,NO)是一种能调节细胞多种功能的信息分子,它参与心血管、外周和中枢神经以及免疫等系统生理过程和生物信号的调节。体内组织中的NO由NO合酶(Nitricoxidesynthase,NOS)催化左旋精氨酸而合成,合成后的NO迅速跨膜扩散释放。各种调节NO释放的因素均作用于NOS催化的化学反应过程,而体内影响该反应的NOS在各组织的表达不同。特异性NOS抑制剂通过调控NO的合成,对NOS表达相关的各种疾病的预防和治疗具有重要的临床意义。本文对近年来NOS抑制剂的研究进展作一概述。
Nitric oxide (NO) is a ubiquitous, naturally occurring molecule found in a variety of cell types and organ systems. It is a double-edged sword, beneficial as a messenger or modulator and for immunology self-defense, but potentially toxic. The formation and signal function of nitric oxide are mainly modulated by nitric-oxide synthase (NOS). Up to the present, a number of diseases, including circulatory shock, atherosclerosis, cardiac allograft rejection, chronic inflammation, cardiac infarction, cancer and so on, have been demonstrated that their pathogenesis may be involved in the sustained production of large quantities of nitric oxide. Animal studies and human studies have shown that specific inhibitors of inducible nitric-oxide synthase may be useful in the therapy of a variety of diseases associated with induction of nitric-oxide synthase. In this review, we compare and contrast these inhibitors along with examples of their use in the studies of medicine.
