Phenotypic screening combined with industry-preferenced target-based approaches that drive the development of innovative chemical biology techniques can facilitate the identification of new therapeutic targets and accelerate drug discovery. A chemical genomic library is a collection of selective small molecule drugs, and whether such a combination is a hit in phenotypic screening. This indicates that the target of the annotation, or the target of the drug, may be included in an observable phenotype that is interfering.
In January 2017, Nature Reviews Drug Discovery published a review that identified the screening opportunities offered by the chemical genome, which greatly accelerated the drug discovery method based on the conversion of phenotypic screening projects into drug targets. The review also discusses other applications, including drug repositioning, predicting toxicology, and discovering new pharmacological approaches.
Chemical genomics appeared in the early 21st century, using family-directed chemical libraries for cell analysis to accelerate drug development. For example, the development of a novel inhibitor of the target kinase can be initiated by screening with a library containing a kinase inhibitor, or it can be based on a kinase constructed from a small molecule that contains a purine analog that is more likely to bind to the ATP binding site. Library start. Over time, the chemical genome now represents the use of pharmacologically regulated all gene products that have evolved to complement existing chemical biology target recognition technologies.
Chemical genomic library screening program
A typical chemical genomic library screening procedure is shown: phenotypic screening of a chemical genomics library (parallel counting screens or broader cytotoxicity and complex fluorescence) can provide biological targets. Pathway analysis of the entire data set results in the generation of causal hypotheses that can identify specific candidate therapeutic targets, which needs to be validated using experiments using complementary techniques. Some methods such as whole genome siRNA or CRISPR–Cas9 screening can perform accelerated target recognition in parallel. Target verification data can be used to improve computer path analysis and generate new assumptions. Ultimately, these efforts may lead to important insights into the phenotype of the survey, new therapeutic targets, or opportunities to reposition the drug.

Examples of chemical genomic library screening collections
This article lists some examples of chemical genomic libraries and describes the issues that need to be addressed when successfully using these collections in phenotypic screening. Libraries of some chemical genomes have been reported in the literature, although the details of the selection criteria for which compounds are included in the collection are sometimes lacking, but the gene families and targets covered by these libraries are described. As a result, the differences between these libraries, their potential advantages and limitations are evident.
