Triazole refers to a heterocyclic compound with the molecular formula C2H3N3, which has a five-membered ring consisting of two carbon atoms and three nitrogen atoms. Neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease already affect many people around the world, and these numbers are increasing rapidly. Treatment for these disorders is often aimed at relieving symptoms and has no cure. Research on new molecules is underway, and heterocyclic compounds have important pharmacological implications. Triazoles and tetrazoles are emerging as new molecules in this field.
Thiazolidine is a heterocyclic organic compound, which is a five-membered saturated ring with a thioether group and an amine group. It is the sulfur analog of oxazolidine. Thiazolidine derivatives have many uses and have a broad spectrum of biological activities. For example, the drug pioglitazone contains a thiazolidine ring. Thiazolidine has three isomers, 2-, 3-, and 4-. Derivatives with a 2-thiazoline ring are the most common.
