Important pharmacophoric features in (a) S-verapamil representing DRY-DRY probes (DRY: yellow hot spots) two hydrophobic groups at a distance of 12.0-12.40 Å from one another that are contributing positively in the activity while DRY-N1 represents a hydrophobic probe (DRY: yellow hot spots) at a distance of 13.20-13.60Å from a hydrogen bond acceptor (N1: blue hotspots). O–TIP outline a hydrogen bond donor (OH) (O: red hot spots) at a distance of 4.80-5.20Å from the edge contributing negatively in the activity. A hydrogen bond acceptor (-NH) (N: blue hotspots) at a distance of 8.8-9.20Å form hydrogen bond donor (O: red hot spots) is also contributing negatively in the activity, (b) R-verapamil is also depicting similar pharmacophoric features as S-verapamil except the distance of 8.8-9.20Å between a hydrogen bond donor (O: red hot spots) and hydrogen bond acceptor (N1: blue hotspots) is absent in R-verapamil, (c) S-norfluoxetine is showing distance of 13.20-13.60Å between hydrophobic (DRY: yellow hot spots) and hydrogen bond acceptor (N: blue hotspots) probes that is contributing positively in the activity while the distance of 8.8-9.20Å between hydrogen bond donor and hydrogen bond acceptor as well as the distance of 4.80-5.20 Å between hydrogen bond donor (O: red hot spots) and molecular edge (TIP: green probes) are contributing negatively in the activity, (d) R-norfluoxetine is also illustrating similar pharmacophoric features as S-norfluoxetine except the distance of 8.8-9.20Å between a hydrogen bond donor (O: red hot spots) and hydrogen bond acceptor (N1: blue hotspots) is absent in R-norfluoxetine, (e) S-Fluoxetine is showing two negative contributing features a hydrogen bond acceptor (-NH) (N: blue hotspots) at a distance of 8.8-9.20Å form hydrogen bond donor and a distance of 4.80-5.20 Å between molecular edge (TIP: green probes) and hydrogen bond donor (O: red hot spots) in the figure, (f) R-fluoxetine is illustrating pharmacophoric features similar to that of S-fluoxetine, (g) S-dichlobutrazol is depicting three important distances including DRY-DRY probes (DRY: yellow hot spots) two hydrophobic groups at a distance of 12.0-12.40 Å, a hydrogen bond donor (OH) (O: red hot spots) at a distance of 4.80-5.20 Å from the edge (TIP: green probes) contributing negatively in the activity. A hydrogen bond acceptor (-NH) (N: blue hotspots) at a distance of 8.8-9.20Å form hydrogen bond donor is also contributing negatively in the activity, (h) R-dichlobutrazol is Supplementary Material displaying identical distances among similar pharmacophoric groups highlighted in S- dichlobutrazol.</p><p>References</p><p>(Molecular Operating Environment (MOE), 2013.08; Chemical Computing Group Inc., 1010 Sherbooke St. West, Suite #910, Montreal, QC, Canada, H3A 2R7, 2015.49.).</p><p>Cheng, F., W.
