Receptor-based Pharmacophore Model Service
Wolber et al. created multiple pharmacophore models based on the protein crystal structures of STI-571 and its homologs (1iep, 1fpu, 1opj). The LigandScout software can be used to merge the pharmacophore models. As shown in the figure, the resulting pharmacophore model contains 4 hydrophobic aromatic groups, 2 aliphatic hydrophobic groups, 2 hydrogen bond donor groups, 1 hydrogen bond acceptor group, and 8 repulsion groups volume group.
Method
The structural information of protein receptors is known, but there is no active ligand. In this case, the putative pharmacophore model can be constructed by analyzing the chemical nature of the target binding site. There are several different calculation methods that can directly convert the 3D atomic structure of the protein binding site into a pharmacophore model. The interactive graphics of the de novo drug design tool LUDI can be used to create pharmacophore queries. HS-Pharm is a knowledge-based method that uses machine learning algorithms to determine the priority of the most interesting interacting atoms and generate interaction maps within the binding sites. The interaction diagram is then converted to pharmacophore characteristics.

Receptor-based pharmacophore model service
- Pharmacological model verification service
Our pharmacological model validation service is to screen the PDB database based on the pharmacophore model. The database contains 2765 drug-like compounds. The screening results of the PDB database indicate that the pharmacophore can find all STI-571 structures without false positive results.
- Virtual screening based on pharmacophore
By screening the Maybridge database, the database contains 59 million compounds. Finally, an active compound was obtained.

In addition to the above services, we can also provide
- 2D or 3D pharmacophore model construction.
- Virtual screening of high-performance computing based on pharmaceutics.
- Advanced machine learning algorithm with pharmacophore fingerprint of target ligand binding pocket.
