The cholesterol pathway is an essential biochemical process aimed at the synthesis of bioactive molecules involved in multiple crucial cellular functions. The end products of this pathway are sterols, such as cholesterol, which are essential components of cell membranes, precursors of steroid hormones, bile acids and other molecules such as ubiquinone. Several diseases are caused by defects in this metabolic pathway: the most severe forms of which cause neurological involvement (psychomotor retardation and cerebellar ataxia) as a result of a variety of cellular impairments, including mitochondrial dysfunction. These pathologies are induced by convergent mechanisms in which the mitochondrial unit plays a pivotal role contributing to defective apoptosis, autophagy and mitophagy processes. Unraveling these mechanisms would contribute to the development of effective drug treatments for these disorders. In addition, the development of biochemical models could have a substantial impact on the understanding of the mechanism of action of drugs that act on this pathway in multifactor disorders. In this review we will focus in particular on inhibitors of cholesterol synthesis, mitochondria-targeted drugs and inhibitors of the inflammasome.
胆固醇途径是一个重要的生化过程,旨在合成参与多种关键细胞功能的生物活性分子。该途径的终产物是固醇类物质,如胆固醇,它们是细胞膜的重要组成成分、类固醇激素、胆汁酸以及其他分子(如泛醌)的前体。几种疾病是由该代谢途径的缺陷引起的:其中最严重的形式会由于包括线粒体功能障碍在内的多种细胞损伤而导致神经受累(精神运动发育迟缓及小脑共济失调)。这些病症是由多种汇聚机制诱导产生的,其中线粒体单元在导致凋亡、自噬和线粒体自噬过程缺陷方面起着关键作用。阐明这些机制将有助于开发针对这些疾病的有效药物治疗方法。此外,生化模型的开发可能会对理解在多因素疾病中作用于该途径的药物的作用机制产生重大影响。在本综述中,我们将特别关注胆固醇合成抑制剂、线粒体靶向药物和炎性小体抑制剂。
