2-Phenyl-4(3H)-quinazolones bearing a urethane or thiourethane group on the 2-phenyl substituent, a second urethane or thiourethane group on the benzo ring of the quinazolone nucleus and an alkyl, cycloalkyl or phenyl group in the 3-position are prepared by treating the corresponding bis-amino compound with an acid derivative or the corresponding bis(isocyanate) or bis(isothiocyanate) with an alcohol. The compounds, of which 2-[3'-(methoxycarbonylamino)-phenyl]-3-phenyl-6-methoxycarbonylamino-4-(3H )-quinazolone is a typical embodiment, are cytostatic agents.
含有尿素或硫脲基团的2-苯基-4(3H)-喹唑酮衍生物,其2-苯基取代基上有一个尿素或硫脲基团,喹唑酮核上的苯环上有第二个尿素或硫脲基团,3-位上有烷基、环烷基或苯基。通过用酸衍生物或相应的双(异)氰酸酯或双(异)硫氰酸酯与相应的双氨基化合物或醇反应制备这些化合物,其中2-[3'-(甲氧羰基氨基)-苯基]-3-苯基-6-甲氧羰基氨基-4-(3H)-喹唑酮是一个典型的实施例,是细胞毒素剂。
