Docking studies of compound 7 with AChE and MAO-B.
(A) Proposed docked pose of 7 in the active site of AChE
(PDB-ID: 1B41). Compound 7 is rendered with cyan sticks. The side-chain
conformations of active site amino acids are shown, including the
mobile residues of Trp86, Tyr72, Asp74, Tyr124, Trp286, Tyr337, and
Tyr341. The catalytic triad is colored in green, the oxyanion hole
in magenta, the CAS and the acyl-binding pocket in orange, and the
PAS in light blue. (B) Binding mode prediction of compound 7 in the active site of MAO-B (PDB-ID: 2V5Z). Compound 7 is rendered
with yellow sticks. The amino acid residues that are involved in inhibitor
binding are shown. The FAD cofactor and the six water molecules as
an integral part of the MAO-B structure model are displayed as orange
sticks and light red balls, respectively. Intermolecular interactions
are shown as dashed lines according to their type: green, hydrogen
bond; blue, hydrogen bond to water; purple, π–π
T-shaped interaction; pink, π–alkyl and alkyl–alkyl
contacts.
