High-throughput screening (HTS) is a method for scientific discovery especially used in drug discovery and relevant to the fields of biology, materials science [1] and chemistry. [ 2 ] [ 3 ] Using robotics , data processing/control software, liquid handling devices, and sensitive detectors, high-throughput screening allows a researcher to ...
Compound management in the field of drug discovery refers to the systematic collection, storage, retrieval, and quality control of small molecule chemical compounds used in high-throughput screening and other research activities to identify hits that can be developed into candidate drugs.
In high-throughput screening (HTS), one of the major goals is to select compounds (including small molecules, siRNAs, shRNA, genes, et al.) with a desired size of inhibition or activation effects. A compound with a desired size of effects in an HTS screen is called a hit. The process of selecting hits is called hit selection. [citation needed]
[3] [4] The drug discovery process generally follows the following path that includes a hit to lead stage: Target validation (TV) → Assay development → High-throughput screening (HTS) → Hit to lead (H2L) → Lead optimization (LO) → Preclinical development → Clinical development
As above mentioned, combinatorial chemistry was a key technology enabling the efficient generation of large screening libraries for the needs of high-throughput screening. However, now, after two decades of combinatorial chemistry, it has been pointed out that despite the increased efficiency in chemical synthesis, no increase in lead or drug ...
Chemogenomics Staubli robot retrieves assay plates from incubators. Chemogenomics, or chemical genomics, is the systematic screening of targeted chemical libraries of small molecules against individual drug target families (e.g., GPCRs, nuclear receptors, kinases, proteases, etc.) with the ultimate goal of identification of novel drugs and drug targets. [1]
Unlike high-content analysis, high-content screening implies a level of throughput which is why the term "screening" differentiates HCS from HCA, which may be high in content but low in throughput. In high content screening, cells are first incubated with the substance and after a period of time, structures and molecular components of the cells ...
A high throughput assay can be either an endpoint or a kinetic assay usually done on an automated platform in 96-, 384- or 1536-well microplate formats (High Throughput Screening). Such assays are able to test large number of compounds or analytes or make functional biological readouts in response to a stimuli and/or compounds being tested. [6]
