Figure 5.

Pharmacophore model and fitting compound. (A) shows the pharmacophore model. (B) Shows the compound and its pharmacophoric features. (C) Shows a superposition of the compound and the pharmacophore, showing that the compound matches four sites in the pharmacophore. The hydrogen bond acceptor, hydrogen bond donor, and aromatic and negative ionizable features are shown in red, blue, and orange and red, respectively. The arrows in the hydrogen bond acceptor and hydrogen bond donor features indicate the direction of the hydrogen bond. This figure was obtained with Maestro [33].
