Novel bioactive compounds as synthetic analogs of the potent herbal medicines can be optimized as potential drug candidates for various neurologic disorders. This study was performed to investigate the newly synthesized dibenzylidene ketone derivatives: (2E,6E)-2,6-dibenzylidene cyclohexanone (A1K1) and (1E,4E)-5-(2,3-dichlorophenyl)-1-(4-methoxyphenyl)-2-methylpenta-1,4-diene-3-one (A2K2) and evaluate its potential anti-Alzheimer's and anti-depressant properties. Both the derivatives are chemically characterized by using HNMR and CNMR techniques. Auto Dock Vina program was used to investigate ligand-protein affinity. Forced swim test, tail suspension test, open field test, Y-maze test, and Morris water maze test (MWM) models were employed to evaluate anti-depressant and anti-Alzheimer's activity of dibenzylidene ketone derivatives in mice. Both A1K1 and A2K2 showed high binding affinities against various proteins involved in depression and Alzheimer's mechanisms like monoamine oxidase B, acetylcholinesterase, norepinephrine transporter 2, serotonin transporter, dopamine receptor, serotonin receptor modulator, and beta-amyloid targets. A1K1 and A2K2 dose-dependently (0.1-1 mg/kg) decreased immobility time, while increased swimming and climbing time of mice in forced swim test (FST). A1K1 and A2K2 decreased animal immobility time in TST. In the open field test, both A1K1 and A2K2 increased the number of ambulations and rearings. A1K1 and A2K2 dose-dependently (0.5-1.0 mg/kg) increased spontaneous alternation behavior (%) and the number of entries of mice in Y-maze test. In the MWM test, A1K1 and A2K2 decreased escape latency time. Overall, both in-silico and in-vivo investigations of A1K1 and A2K2, report their therapeutic potential for antidepressant and anti-Alzheimer properties. Hence, these compounds possess potent neuroprotective properties and may be further evaluated for their therapeutic potential in various neurological disorders.

A computer simulation technique that is used to model the interaction between two molecules. Typically the docking simulation measures the interactions of a small molecule or ligand with a part of a larger molecule such as a protein.
An IBUPROFEN-type anti-inflammatory analgesic and antipyretic. It inhibits prostaglandin synthesis and has been proposed as an anti-arthritic.
Anti-inflammatory agents that are not steroids. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They are used primarily in the treatment of chronic arthritic conditions and certain soft tissue disorders associated with pain and inflammation. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects. Certain NSAIDs also may inhibit lipoxygenase enzymes or TYPE C PHOSPHOLIPASES or may modulate T-cell function. (AMA Drug Evaluations Annual, 1994, p 1814-5)
The molecular designing of drugs for specific purposes (such as DNA-binding, enzyme inhibition, anti-cancer efficacy, etc.) based on knowledge of molecular properties such as activity of functional groups, molecular geometry, and electronic structure, and also on information cataloged on analogous molecules. Drug design is generally computer-assisted molecular modeling and does not include pharmacokinetics, dosage analysis, or drug administration analysis.
