Biological aspects of nitrogen heterocycles for amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS) is a rare, cumulative neurological deteriorating disease that disturbs the neurons (nerve cells) that control voluntary muscle movement (those muscles we choose to move). Currently, the Food and Drug Administration (FDA) approved drugs such as Radicava, Rilutek, Tiglutik, Exservan, and Nuedexta to treat ALS. Given the wide range of pharmaceutical applications of heterocyclic compounds, especially those containing the nitrogen ring systems such as pyridine, pyrimidine, and indole. These molecular frameworks have piqued the interest of medicinal chemists for further investigation in a variety of diseases. We have found several review works done on this research topic. Until now, no reviews published on the nitrogen heterocycles for treating ALS. This review examines the major causes of ALS, a brief history of medications that have been used to treat it so far, and the most recent breakthroughs in nitrogen ring systems for treating ALS. The novelty of this study provides insights on several effective synthetic techniques for nitrogen-based heterocyclic medications that operate as potent anti-inflammatory treatments and guard against ALS. KEY POINTS: • Pharmacological activity of heterocyclic compounds. • Neurodegenerative diseases and their drawbacks are discussed in detail. • Recent survey of nitrogen heterocycles in treating ALS disease are highlighted.
