Medchemexpress LLC Tiotropium Bromide | 136310-93-5 | 99.9% | 472.42 | 500 MG

Tiotropium Bromide is a potent muscarinic acetylcholine receptor (mAChR) antagonist. It works by blocking the binding of acetylcholine, which prevents the opening of ligand-gated ion channels. This action leads to the cessation of neuronal signaling and muscle relaxation. As a long-acting, 24-hour anticholinergic bronchodilator, it is widely used in the management of chronic obstructive pulmonary disease and can also alleviate symptoms in cases complicated by chronic heart failure.

D-α-Hydroxyglutaric acid is the primary metabolite accumulating in D-2-hydroxyglutaric aciduria, a neurometabolic disease. It acts as a weak competitive antagonist of α-ketoglutarate (α-KG) and inhibits multiple α-KG-dependent dioxygenases. This compound also enhances reactive oxygen species (ROS) production, binds to and inhibits ATP synthase, and suppresses mTOR signaling. It accumulates in human cancers with specific mutations in IDH1 and IDH2 genes.
