There are several drug targets which are reported to control the severe level of AD; notably, acetylcholinesterase, β-Secretase and glycogen synthase kinase enzymes are approached as a good drug targets for AD. Hence, the present study mainly focused to discover newly synthesized molecule (7-propyl-6H-pyrano[3,2-c:5,6-c']dichromene-6,8(7H)-dione) as a potential triplet acting drug for above said enzymes through the analysis of X-ray crystallography, molecular docking, molecular dynamics and quantum chemical calculation. The target drug molecule was crystallized in the monoclinic crystal structure with P21/n space group. The structure was solved by SHELXS and refined by SHELXL. The crystal packing is stabilized by C − H···O type of interactions. Further, the induced fit docking shows that the molecule has high docking score, glide energy, favorable hydrogen bonding and hydrophobic interactions on the protein targets. The molecular dynamics simulation was performed to understand the stability of the molecule in the presence of active site environment. Finally, quantum chemical calculation has been carried out for the molecule in gas phase and for the corresponding molecule lifted from the active site region. The structural comparison between gas phase and active site helps to understand the conformational modification of the molecule in the active site. </p> <p>Communicated by Ramaswamy H.
