What are Undruggable targets?

What are Undruggable targets?

Undruggable targets refer to clinically meaningful therapeutic targets that are ‘difficult to drug’ or ‘yet to be drugged’ via traditional approaches.

Where can I find drug targets?

Identification of the target is followed by characterization of the molecular mechanisms addressed by the target. A good target should be efficacious, safe, meet clinical and commercial requirements and be “druggable”.

What are therapeutic targets?

Therapeutic target may refer to: Biological target, a protein or nucleic acid whose activity can be modified by an external stimulus. Therapeutic Targets Database, a database to provide information about the known and explored therapeutic targets. Therapeutic target range, an alternative reference range.

What is the most common target for drugs?

The most common drug targets of currently marketed drugs include:

  • proteins. G protein-coupled receptors (target of 50% of drugs) enzymes (especially protein kinases, proteases, esterases, and phosphatases) ion channels. ligand-gated ion channels. voltage-gated ion channels. nuclear hormone receptors.
  • nucleic acids.

What does Undruggable mean?

The term ‘undruggable’ was coined to describe proteins that could not be targeted pharmacologically. However, progress is being made to ‘drug’ many of these targets, and therefore more appropriate terms might be ‘difficult to drug’ or ‘yet to be drugged’.

Is RNA druggable?

There is currently only a single human-designed and approved drug class that functions by binding RNA alone — the linezolid antibiotics, linezolid and tedizolid (Fig. 2).

How do you identify druggable targets?

Identifying a biological target that is ‘druggable’ – a target is termed ‘druggable’ if its activity (behavior or function) can be modulated by a therapeutic – whether it be a small molecule drug, or biologic. Proteins and nucleic acids are both examples of biological targets.

How do you evaluate a drug target?

In evaluating potential drug targets, several factors must be taken into account: linkage to disease, tractability (the possibility of finding small molecule compounds with high affinity), potential side effects, novelty, as well as the competitiveness in the market ( Figure 1).

How many Undruggable targets are there?

In fact, it’s estimated that out of roughly 4,000 disease-related targets known to us today, only a quarter actually have a medicine that can reach and act on them. Researchers sometimes call these elusive targets “undruggable.”

How many druggable targets are there?

The NMR data set derived from the original publication by Hajduk et al. consists of 10 druggable and 14 undruggable sites, where “druggable” is defined as having a known high-affinity (Kd < 300 nmol/l), nonpeptide, noncovalent inhibitor.
