Thiazolines are a group of isomeric five-membered heterocyclic compounds containing both sulfur and nitrogen. Thiazoline exists in three isomeric forms namely 2-thiazoline, 3-thiazoline and 4-thiazoline. Oxazolines, oxazoles, thiazolines, and thiazoles form the characteristic heterocyclic building blocks of lissoclinum peptide alkaloids.
Thiazoles are very important functional groups in medicinal chemistry. They act as ligands on a variety of biological matrices. Thiazoles are used in a wide range of therapeutic applications, such as antibacterial, antiretroviral, antifungal, antiallergic, antihypertensive, pain treatment, and to control symptoms of schizophrenia.
