In the design of novel drugs, the formation of hybrid molecules via the combination of several pharmacophores can give rise to compounds with interesting biochemical profiles. A series of novel quinazolin–sulfonamid derivatives (9a–m) were synthesized, characterized and evaluated for their in vitro antidiabetic, anticholinergics, and antiepileptic activity. These synthesized novel quinazolin–sulfonamid derivatives (9a–m) were found to be effective inhibitor molecules for the α-glycosidase, human carbonic anhydrase I and II (hCA I and hCA II), butyrylcholinesterase (BChE) and acetylcholinesterase (AChE) enzyme, with Ki values in the range of 100.62 ± 13.68–327.94 ± 58.21 nM for α-glycosidase, 1.03 ± 0.11–14.87 ± 2.63 nM for hCA I, 1.83 ± 0.24–15.86 ± 2.57 nM for hCA II, 30.12 ± 3.81–102.16 ± 13.87 nM for BChE, and 26.16 ± 3.63–88.52 ± 20.11 nM for AChE, respectively. In the last step, molecular docking calculations were made to compare biological activities of molecules against enzymes which are achethylcholinesterase, butyrylcholinesterase and α-glycosidase.

A new series of quinazolinone-2-thio-metronidazole derivatives 9a-o was designed, synthesized and assayed for their activities against metabolic enzymes human carbonic anhydrase I and II (hCAs I and II), acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and α-glucosidase. The results indicated that all the synthesized compounds exhibited excellent inhibitory activities against mentioned enzymes as compared with standard inhibitors. Representatively, the most potent compound against CA enzymes, 4-fluorophenyl derivative 9i, was 4 and 7-times more potent than standard inhibitor acetazolamide against hCA I and II, respectively; 4-fluorobenzyl derivative 9m as the most potent compound against cholinesterase enzymes, was around 11 and 21-times more potent than standard inhibitor tacrine against AChE and BChE, respectively; the most active α-glucosidase inhibitor 9h with 4-methoxyphenyl moiety was 5-times more active that acarbose as standard inhibitor. Furthermore, in order to study interaction modes of the most potent compounds in the active site of their related enzymes, molecular modeling was performed. Druglikeness, ADME, and toxicity profile of the compounds 9i, 9m, and 9h were also predicted.

Quinazolinone and quinazolinedione derivatives are of considerable interest due to their wide array of pharmacological properties. In this paper we report the synthesis of ten quinazolinediones. The previous isolation of two of these compounds, namely 1-methyl-3-(2′-phenylethyl)-1H,3H-quinazoline-2,4-dione and 1-methyl-3-[2′-(4′-methoxyphenyl)ethyl]-1H,3H-quinazoline-2,4- dione, from the seed husks of Mexican Zanthoxylum species has been reported.
