Chemical Properties
Beige to brownish crystalline powder
Uses
Quinazoline was used to study the electrochemical behaviour of quinazoline using modern polarographic and voltammetric methods. It is the basic structural unit of pharmaceuticals and plays an important role in modern synthesis of antitumor drugs.
Definition
ChEBI: A mancude organic heterobicyclic parent that is naphthalene in which the carbon atoms at positions 1 and 3 have been replaced by nitrogen atoms.
General Description
Quinazolines has applications in medicinal chemistry due to their antibacterial, antifungal, anticonvulsant, anti-inflammatory and antitumor activities. It is the basic structural unit of pharmaceuticals and plays an important role in modern synthesis of antitumor drugs.
Biochem/physiol Actions
Genotoxicity of quinazoline was established by bacterial SOS Chromotest (Escherichia Coli).
Purification Methods
Purify quinazoline by passage through an activated alumina column in *C6H6 or pet ether (b 40-60o). Distil it under reduced pressure, sublime it under vacuum and crystallise it from pet ether. The picrate has m 188-189o (from MeOH).
