- Synthesis of Novel Pyrimidin-4-One Bearing Piperazine Ring-Based Amides as Glycogen Synthase Kinase-3β Inhibitors with Antidepressant Activity
-
Novel pyrimidin-4-one derivatives have been synthesized using EDC coupling and evaluated as glycogen synthase kinase-3β (GSK-3β) inhibitors. Among all the synthesized compounds, compound 5 (3-methyl-6-phenyl-2-(piperazin-1-yl)-3,4-dihydropyrimidin-4-one) exhibited the most potent inhibitory activity against GSK-3β with IC50 value of 74 nm. The molecular docking studies were performed to elucidate the binding modes of the compounds with the target, and a crucial interaction involving hydrogen bond formation with Val-135 to the active site of GSK-3β was observed. Furthermore, the synthesized compounds were subjected to in vivo evaluation of their antidepressant activity, and compound 5 showing highest inhibition of GSK-3β was also found to significantly reduce the duration of immobility at 50 mg/kg, when compared with fluoxetine, a known antidepressant drug. The results of our study suggest that compound 5 may serve as a valuable template for the design and development of inhibitors of GSK-3β with antidepressant activity.

- Highly Regioselective Synthesis of 3,6-Disubstituted 2-(Methylsulfanyl)pyrimidin-4(3 H)-ones
-
This study reports a simple and highly regioselective synthesis of a new series of 3,6-disubstituted 2-(methylsulfanyl)pyrimidin-4(3H)-ones, in which the 6-substituents are methyl or aryl groups and the 3-substituents are alkyl, allyl, phenyl, benzyl, or 2-phenylethyl groups. The products are obtained in good yields by cyclocondensation of the appropriate 4-substituted 4-methoxy-1,1,1-trichloroalk-3-en-2-ones with nonsymmetric 1-substituted 2-methylisothiourea sulfates under mild basic conditions.
