From: Anthelmintic activity of Piper sylvaticum Roxb. (family: Piperaceae): In vitro and in silico studies
Docking results of Levamisole (standard drug), piperine, piperlonguminine, and N-isobutyl deca-trans-2-trans-4-dienamide with TUBULIN-COLCHICINE enzyme (PDB: 1SAO) for anthelmintic activity. The colors indicate the residue (or species) type: Red-acidic (Asp, Glu), Green-hydrophobic (Ala, Val,Ile, Leu, Tyr, Phe, Trp, Met, Cys, Pro), Purple-basic (Hip, Lys, Arg), Blue-polar (Ser, Thr, Gln, Asn, His, Hie, Hid), Light gray-other (Gly, water), Darker gray-metal atoms. Interactions with the protein are marked with lines between ligand atoms and protein residues: Solid pink—H-bonds to the protein backbone, Dotted pink-H-bonds to protein side chains, Green—pi-pi stacking interactions, Orange-pi-cation interactions. Ligand atoms that are exposed to solvent are marked with gray spheres. The protein “pocket” is displayed with a line around the ligand, colored with the color of the nearest protein residue. The gap in the line shows the opening of the pocket
