describes the synthesis and evaluation of new dihydropyrimidinone (DHPM)-derived selenoesters as potential multi-targeted agents for the treatment of Alzheimer’s disease. A series of DHPM-derived selenoesters were obtained with high structural diversity through a short and modular synthetic route. The antioxidant activity was evaluated by TBARS and iron chelation assays. These compounds were also evaluated

In this paper we report the design, synthesis and evaluation of a series of seleno-dihydropyrimidinones as potential multi-targeted therapeutics for Alzheimer's disease. The compounds show excellent results as acetylcholinesterase inhibitors, being as active as the standard drug. All these compounds also show very good antioxidant activity through different mechanisms of action.

Al2O3/CH3SO3H (AMA) is an efficient catalyst for the three-component condensation reaction of aldehyde, 1,3-dicarbonyl compound, and urea or thiourea to afford the corresponding 3,4-dihydropyrimidin-2-(1H)-ones in high isolated yield via this procedure, which works very effectively regardless of the electronic nature of the substituent on the ring, although electron-donating groups precipitate the rate of reaction. The catalyst is recyclable and stable at room temperature, and the reaction protocol is simple, is cost-effective, and gives good isolated yield with high purity.

Modern organic synthesis is primarily focused on developing environmentally benign synthetic protocols by employing green chemistry principles. Accordingly, in our recent research work, we herein report the use of modified supramolecular host cyclodextrin as an effective solid based green catalyst for accessing structurally diverse and medicinally relevant pyrimidone architectures. The catalyst and the synthesized compounds 4 (a-r) were characterized using FT-IR, NMR and GC-mass spectroscopy. Major highlights of the reported work include the economical atom process, remarkably gentler reaction conditions, ease of operation, high isolated yields, and excellent catalyst turnover numbers. The molecular docking studies suggest that the compound 4n has hydrogen bonding, hydrophobic and π-pair interactions with the active site of the CXT M 15 receptor. Further, the in-vitro antibacterial study as well as the screening of anti-biofilm activity resulted in a BIC value of 76.79 ± 0.785% at a concentration of 10 µg/mL and morphological alterations induced by DHPMs against the ESBL E. coli strain aggregated with a good result.
