Abstract

4 (3H)-Quinazolinones 1 are known for more than a century [1]. Molecules based on quinazoline and quinazolinone exhibit a multitude of interesting pharmacological activities [2], including anticonvulsant, antibacterial and antidiabetic activity [3, 4]. The important natural and synthetic 4 (3H)-quinazolinones include l-vasicinone 2 [5], chrysogine 3 [6], methaquinalon 4 [7]–a sedative, piriqualone 5 [8, 9]–an anticonvulsant, although the latter ...
