I-Quinazoline yinkomfa yendalo kunye nefomula C8H6N2. I-heterocycle enamakha ne-bicyclic isakhiwo esinezikhonkwane ezimbini ezinamakha amanqatha, isandeni ye-benzene kunye ne-pyrimidine ring. Yinto eqinileyo yecreenstalline eqinile enqabileyo emanzini. Eyaziwa nangokuthi i-1,3-diazanaphthalene, i-quinazoline yafumana igama layo ekubeni yi-aza derivative ye-quinoline. Nangona umzali we-quinazoline i-molecule engaqatshelwa ngokungaqhelekanga ngokwayo kwincwadi yezobugcisa, izixhobo ezivela endaweni eziye zenziwe zenzelwe iinjongo zokwelapha ezifana ne-antimalarial kunye ne-antiticancer agents,
Ukuvunyelwa i-afatinib, isilwanyana esikhishwe nguBoehringer Ingelheim.
U-Erlotinib, isilwanyana esenziwe yi-Astellas, ukunyanga izigulane ze-NSCLC ngeesisu ezibangelwa yiinguqu ze-EGFR.
I-lapatinib yeGlaxoSmithKline yayiphatha isigaba esiphambili okanye umdlavuza webele we-metastatic kunye ne-Roche's capecitabine.
