چکیده

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 type of activity does not seem confined to pyridine derivatives of 4(3H)-quinazolinone [10]. Febrifugine 6 and isofebrifugine 7 were known as potent but toxic antimalarial agents long before their initial isolation [11] and recent chemical studies [12-15].

Synthesis of some new tricyclic 4(3H)-quinazolinone derivatives

Quinazolinones are interesting molecules with a wide range of biological activities. We prepared a number of quinazolinone derivatives by the condensation of 5-bromo- or 5-nitro-substituted anthranilic acids with chloro-acyl chlorides. Anthranilic acid derivatives were treated with either 3-chloro-propionyl chloride or 4-chloro-butyryl chloride to yield the corresponding N-acyl-anthranilic acid...
