Hence, the multi-target approach seems plausible en route to the development of therapeutics targeting Alzheimer's in particular, and other neurological disorders, in general. Among the major factors responsible for AD are acetylcholinesterase and monoamine oxidase enzymes. Acetylcholine is an important neurotransmitter that plays a role in processing memory and learning. Deficiency of this neurotransmitter is observed in patients of AD; this is largely attributed to increased expression of the enzyme acetylcholinesterase (AChE) that is responsible for breakdown of acetylcholine neurotransmitter. Hence, inhibitors of AChE can prevent excessive breakdown of this important neurotransmitter. Monoamine oxidases in the brain are responsible for hydrolyzing important neurotransmitters such as serotonin and dopamine (among others), abnormally rapid hydrolysis of these neurotransmitters via over-activation of monoamine oxidases is associated with several neurodegenerative disorders including anxiety and Parkinson's disease. Herein, we synthesized a focused library of 1,4-dihydropyrimidines (40 compounds) using a deep eutectic solvent and evaluated their potential to inhibit cholinesterase (AChE and BChE) and monoamine oxidase (MAO A and MAO B) enzymes. Several selective and highly potent inhibitors were identified; in silico molecular docking and molecular dynamics simulation studies helped to rationalize the binding site interactions and establish useful structure activity relationship.

Surprisingly, the adsorption energy of nitrogen on C<sub>n</sub>P clusters is generally lower than that on pure carbon clusters, which contradicts conventional expectations based solely on carbon. Intriguingly, instances occur where the adsorption energy on C<sub>n</sub>P clusters exceeds that on pure carbon clusters. Notably, the study reveals that even a pure carbon dimer can completely dissociate dinitrogen, suggesting its potential as a catalyst. Examining various cluster sizes, including dimers, trimers, and tetramers, the research elucidates that how configurations and orientations of adsorbed nitrogen molecules significantly impact adsorption properties. These insights underscore the potential of C<sub>n</sub>P clusters as the efficient catalysts for breaking the strong triple bond of dinitrogen. This research delivers unexpected findings that contribute significantly to the field of cluster catalysis and offers a novel perspective on nitrogen fixation processes.
