Chemo informatics is designed, create, organize, manage, search, analyze, disseminate, visualize, and use the chemical information of certain compound. It is basically used to identify target molecules, either genes or proteins that may be therapeutics for disease (gene/protein analysis). Since one of the major applications of cheminformatics in research is drug discovery and development, cheminformatics can greatly improve this process. Many techniques are available to accomplish this, and the use of software to calculate and visualize structures is of great importance. Artificial intelligence is major application of the chemo informatics. Artificial Intelligence (AI) applied to drug discovery has been used to design compounds in medicinal chemistry since the 1960s. Machine learning tools such as quantitative structure-activity relationship modelling (QSAR) have identified potential target molecules from millions of candidate compounds. Computational chemistry should set relevant selection criteria. Compounds of interest for synthesis and assay. Affinity prediction accuracy.
Current methodologies are approaching accuracy sufficient to use. Cheminformatics provides advanced high-throughput screening drug discovery, including identification of drug targets and compounds active against these targets, HTS data mining, and prediction of bioactivity and absorption, distribution, metabolism, excretion and toxicity (ADMET) properties. It plays many roles in research of lead compounds. Generating virtual libraries. There are many chemical libraries and databases available, but cheminformatics allows researchers to create libraries that are not limited to compounds that can be purchased or created, or even compounds that exist in current databases. Diversity, ADMET properties, and synthetic accessibility are important considerations when generating these libraries. These libraries are often designed to track HTS hits and are used to study structure-activity relationships and ADMET properties of hits and structurally similar molecules.
Virtual HTS. Virtual HTS using a cheminformatics approach has become an important tool for lead identification in drug discovery. Virtual HTS can be used to filter out unwanted compounds from libraries based on criteria such as solubility and ADMET properties. It can also be used to screen large insilico libraries to identify compounds with desired propertiesand to gather preliminary information for experimental HTS. Virtual HTS methods include docking calculations when the target structure is known, structural similarity searches when the ligand is known but the target structure is unknown, and quantitative structure-activity relationships when both structures are unknown (QSAR) modelling included.
Bioactivity prediction: His traditional HTS drug discovery workflow often used in vivo and in vitro tests, and ultimately clinical trials, to determine the biological activity of potential drugs. However, predicting biological activity prior to these steps has been shown to reduce drug failure rates in clinical trials. QSAR can be used to relate chemical structure to biological activity and predict the activity of new compounds based on experimental data.
In silico ADMET. Considering ADMET characteristics is very important in drug discovery, as 40% of drug candidates fail due to his poor ADMET prospects. Cheminformatics allowed us to predict the ADMET properties of large pools of compounds prior to HTS, saving time and money. In silico predictions and models enable a better understanding of drug physical and chemical properties related to compound absorption, distribution, metabolism, excretion and toxicology.
Volume of database: The volume of HTS data and chemical database entries has created a need to integrate chemin for matics into high-throughput drug discovery workflows. Chemin for matics enables management, understanding, and visualization of chemical data in support of HTS efforts.
The primary cheminformatics approaches used in HTS drug discovery are descriptor computation, structural similarity search, and classification algorithms. A descriptor is a mathematical representation of information associated with a particular molecule. This allows quantification of molecular properties such as the number of individual atomic species, number of rotatable bonds, log P values, and polarizability. Structural similarity searching is based on the principle that structurally similar molecules behave similarly. Classification algorithms use machine learning to classify compounds as active or inactive and predict unknown properties. Machine learningtechniques include artificial neural networks, support vector machines, and decision tree-based models.
