4-(3H)-quinazolinones N-3 substituted with a five membered heterocycle: A promising scaffold towards bioactive molecules

The quinazolinone nucleus represents, among the class of fused heterocycles, a very important scaffold to obtain molecules with biological activities. A review literature revealed how such kind coming from natural or synthetic source, are associated wide range This is mainly directed towards 4-(3H)-quinazolinones N-3 substituted five membered heterocycle in which all possible combinations nitrogen, sulfur and oxygen atoms present.
