Jul - Aug 2006 Convenient Synthesis of Some 1057 2 - Substituted 4 ( 3 H ) - Quinazolinone Derivatives
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, piriqualo...

In the present work, a series of new N’-[{5-(4-aryl) 1,3-thiazol-2yl}carbohydrazide-methyl]- 3(4-arylimino) indol-2-one analogs (5a-g) had heen synthesized from 3-(4-arylimino)-2-oxo- 1-indole-acetylthiosemicarbazide (4a-g) in ethanol, in the presence of phenacyl bromide or substituted phenacyl bromides. The compound 5e was characterized by its elemental analysis, IR, 1 HNMR and Mass Spectrosco...
متن کاملMicrowave assisted synthesis and antimicrobial activity of 2-quinoxalinone-3-hydrazone derivatives.
A simple and efficient method has been developed for the synthesis of various 2-quinoxalinone-3-hydrazone derivatives using microwave irradiation technique. The series of 2-quinoxalinone-3-hydrazone derivatives synthesized, were structurally confirmed by analytical and spectral data and evaluated for their antimicrobial activities. The results showed that this skeletal framework exhibited marke...
متن کاملSynthesis and Antimicrobial Study of Pyrimidinone Substituted 4(3H)-Quinazolinone Derivatives
Heterocyclic scaffold has been under discovery due to their considerable therapeutic and medicinal importance. One of such heterocycles 2-pyrimidinone, while not naturally occurring, are receiving increased attention because of their wide-ranging biological activity like, an efficient inhibitor of DNA synthesis in E. coli, inhibitors of the enzyme cytidinedeaminase, and as metaphase inhibitors....
