Benzothiophene is an aromatic organic compound with the molecular formula C8H6S and a naphthalene-like odor. Benzothiophenes are used in research as a starting material for the synthesis of larger, often biologically active structures. It exists in medicinal chemical structures such as raloxifene, zileuton, and sertaconazole, and can also be found in BTCP. It is also used to make dyes such as thioindigo.
Imidazolines are a class of heterocycles derived from imidazoles by reduction of one of the two double bonds. Three isomers are known, 2-imidazoline, 3-imidazoline and 4-imidazoline. 2 and 3-imidazolines contain imine centers, while 4-imidazolines contain alkene groups. The 2-imidazoline group occurs in several drugs. Imidazolines are an important class of compounds found in many natural and medicinal products. These compounds are also used as intermediates in the synthesis of organic molecules. Furthermore, chiral imidazolines are widely used as organic catalysts for the synthesis of various natural and synthetic organic compounds.
The imidazothiazole, consisting of an imidazole ring fused with a thiazole ring, has been reported to have excellent immunostimulating and anti-inflammatory activities. Fused heterocyclic compounds are of great importance and are found in various types of synthetic and naturally occurring biologically important compounds. Imidazothiazoles and imidazopyridines possess a variety of applications such as dyes, pesticides, fungicides, antitumor, antiinflammatory, and analgesic activity.
