Quinazolinone derivatives of the formula, ##SPC1## Wherein R is a polyalicyclic hydrocarbon group; R.sup.1 and R.sup.2 are independently a hydrogen atom, a nitro group, a trifluoromethyl group or a methylsulfonyl group; R.sup.3 is a phenyl group, a substituted phenyl group, a pyridyl group or a thienyl group; and n is 0 or an integer of 1 to 3, have potent antiviral activity with low toxicities. These compounds can be prepared using a variety of processes analogous to known methods, for example, by oxidizing a 3,4-dihydro-2(1H)-quinazolinone having a polyalicyclic hydrocarbon group bonded through an alkylene group at the 1 position.
公式为##SPC1##的喹唑啉酮衍生物,其中R为多环烃基;R.sup.1和R.sup.2分别为氢原子、硝基、三氟甲基或甲磺酰基;R.sup.3为苯基、取代苯基、吡啶基或噻吩基;n为0或1至3的整数,具有强效的抗病毒活性和低毒性。这些化合物可以使用类似已知方法的各种过程制备,例如通过氧化在1位通过烷基链与多环烃基键合的3,4-二氢-2(1H)-喹唑啉酮。
