Target identification is the process of identifying the direct molecular target (e.g., protein or nucleic acid) of a small molecule, which is approached by direct biochemical methods, genetic interactions or computational inference. It has a very important role in small molecule probing and drug discovery, and is required to fully characterize on-target and off-target effects and to understand a drug's mechanism of action.
Generally, there are two scenarios for which you want to perform a drug identification analysis. The first scenario is you "have a drug of efficacy but the target is unknown". The other is you "need to find a target for new drug discovery and development". In either scenario, CD BioSciences offers satisfying solutions grounded in a number of different strategies and technologies to meet your needs.
Our Target Identification Strategies
"Want A Compound"
In a target-based drug discovery process, target identification is also known as target discovery, where a druggable target needs to be established before a drug screening. That is, a gene or a protein with known functions in a disease process is identified to generate drug screening assays.
CD BioSciences offers strategies to identify druggable targets in the "Want A Compound" scenario including but not limited to the following.
Detecting and comparing expressions of genes in normal conditions with those in pathological or diseases conditions by mRNA-seq, microarrays, etc.
Detecting, quantifying and comparing expression levels of proteins in normal conditions with those in pathological or diseases conditions by mass spectrometry, antibody array, etc.
Data mining to identify genetic mutations or polymorphisms associated with disease using bioinformatics.
Identifying genes responsible for a particular phenotype using RNAi or CRISPR screening.
Analyzing disease related signaling pathways and identifying druggable targets.
"Have A Compound"
In a phenotype-based drug discovery process, target identification is also known as target deconvolution, where the determination of the molecular target is after the drug has been proved to exert the desired effect.
CD BioSciences offers strategies to identify drug targets in the "Have A Compound" scenario including but not limited to the following.
Identifying gene manipulations with the ability to reverse drug's effect by RNAi (i.e., shRNA, siRNA library) screening or CRISPR (i.e., CRISPR KO, CRISPRi, CRISPRa) screening.
Identifying proteins after blocked by antibodies can reverse the drug's effects.
In vitro pulldown using the drug (with tag) as bait to capture proteins or other molecules bound to them and identifying with mass spectrometry.
Advantages of Drug Target Identification
- It allows the identification of the drug target and uncovers the drug's mechanism of action (MOA).
- It provides evidence to support the drug's efficacy and safety (e.g., whether it has off-target effects).
- It allows the future discovery of therapeutics that act at the specific target of interest.
