Chemical Structure
Tiagabine hydrochloride hydrate
Synonym(s): NO050328 hydrochloride hydrate; NO328 hydrochloride hydrate; TGB hydrochloride hydrate
- CAS No.: 145821-57-4
- Formula:C20H28ClNO3S2
- Molecular Weight:430.02
IUPAC Name: (R)-1-(4,4-bis(3-methylthiophen-2-yl)but-3-en-1-yl)piperidine-3-carboxylic acid hydrochloride hydrate
InChIKey: KOZCGZMZXXVHCF-GGMCWBHBSA-N
SMILES: O=C([C@H]1CN(CC/C=C(C2=C(C)C=CS2)/C3=C(C)C=CS3)CCC1)O.[H]Cl.O
Biological Activity: Tiagabine (NO050328; NO328; TGB) hydrochloride hydrate is an orally active, highly selective, and reversible GAT-1 inhibitor and anticonvulsant that crosses the blood-brain barrier. By blocking the reuptake of GABA in neurons and glial cells, tiagabine increases extracellular GABA levels to enhance inhibitory signal transduction, thereby exerting multiple activities such as anticonvulsant, neuroprotective, and antioxidant effects. Tiagabine hydrochloride hydrate exhibits linear pharmacokinetic properties. Although it is metabolized by CYP3A and has a high protein binding rate, it carries a low risk of cognitive impairment. Tiagabine hydrochloride hydrate is widely used in research on related diseases including epilepsy (including refractory partial seizures), alcohol withdrawal symptoms, and Huntington's disease[1][2][3][4][5][6].
