The process for developing a pharmacophore model generally involves the following steps: Select a training set of ligands – Choose a structurally diverse set of molecules that will be used for developing the pharmacophore model. As a pharmacophore model should be able to discriminate between molecules with and without bioactivity, the set of ...
The combined use of a pharmacophore model, assembled from highly optimized TRPV1 antagonists, with a homology model of the protein has enhanced understanding of the observed structure–activity relationships of many series of current TRPV1 antagonists, and should be useful in the discovery of new classes of antagonists.

Pharmacophore There are three functional groups that are the most important parts for the bioactivity of ARBs, see figure 1 for details. The first one is the imidazole ring that binds to amino acids in helix 7 (Asn 295). The second group is the biphenyl-methyl group that binds to amino acids in both helices 6 and 7 (Phe 301, Phe 300, Trp 253 ...
LigandScout is computer software that allows creating three-dimensional (3D) pharmacophore models from structural data of macromolecule–ligand complexes, or from training and test sets of organic molecules.
The pharmacophore of 5-HT 3 receptors consists of three components: a carbonyl-containing linking moiety, aromatic/heteroaromatic ring, and a basic center. The carbonyl group is coplanar to the aromatic ring . 5-HT 3 receptor antagonists are more likely to bind in their protonated form. [ 45 ]
Ideally, the structure of a drug target is known, which allows for structure-based pharmacophore modeling. A structure-based model integrates key structural properties of the protein's binding site, such as the spatial distribution of interaction points, with features identified from ligand based pharmacophore models to generate a holistic ...
Pharmacophore models have been made based on key chemical features of compounds with DPP-4 inhibitory activity. These models can provide a hypothetical picture of the primary chemical feature responsible for inhibitory activity. [5] The first DPP-4 inhibitors were reversible inhibitors and came with bad side effects because of low selectivity.
