Chemistry Heterocyclic Building Blocks Quinazolines

Quinazolines

Quinazoline is a bicyclic aromatic heterocycle comprised of two fused six-membered rings, a benzene ring and a pyrimidine ring, and has the molecular formula C8H6N2.

Quinazoline is a heterobicyclic organic compound that can be considered as the parent compound of molecules containing a fused two-ring system. It is derived from naphthalene by replacing the carbon atoms at positions 1 and 3 with nitrogen atoms.

Quinazoline, which is a benzo-fused pyrimidine, can also be referred to as benzo[d]pyrimidine according to the fusion nomenclature or as 1,3-diazanaphthalene using the replacement nomenclature.

Quinazoline, which consists of two fused six-membered aromatic rings, exhibits hypotensive and anticancer properties. Quinazoline-derived drugs such as prazosin, doxazosin, and terazosin act as α1-adrenergic receptor blockers.

While the parent quinazoline molecule is not frequently referred to in technical literature, its substituted derivatives have been created for medicinal uses like as antimalarial and anticancer agents.
