Receptors are proteins found on the surface of cells or within cells that bind to specific molecules, such as hormones, neurotransmitters, or drugs. When a molecule binds to a receptor, it triggers a series of biochemical reactions within the cell that can lead to a variety of physiological effects.
Receptors are important targets for drug discovery because they play a critical role in regulating many physiological processes, such as metabolism, inflammation, and neurotransmission. By targeting specific receptors with drugs, it is possible to modulate their activity and affect the underlying physiological processes in a therapeutic way.
There are many different types of receptors, and each type has its own unique structure and function. For example, G protein-coupled receptors (GPCRs) are a large family of receptors that are involved in a wide range of physiological processes, including sensory perception, hormone signaling, and neurotransmission. Many drugs, including antihistamines, beta-blockers, and antidepressants, target GPCRs.
Ion channels are another important class of receptors that are involved in a wide range of physiological processes, including neuronal signaling, muscle contraction, and cell proliferation. Many drugs that target ion channels are used to treat diseases such as epilepsy, hypertension, and arrhythmias.
In recent years, advances in technology, such as high-throughput screening and computational modeling, have greatly accelerated the discovery of new drugs that target receptors. These approaches allow researchers to screen large numbers of compounds for their ability to bind to specific receptors and identify potential drug candidates.
Overall, targeting receptors is an important approach for drug discovery and has led to the development of many important drugs that are used to treat a wide range of diseases.
The use of receptors as a target for drug discovery is a rapidly growing field in the pharmaceutical industry. Receptors are proteins found on the surface or within cells that bind to specific molecules, such as hormones or neurotransmitters, to initiate a cellular response.
The global market for receptor-targeted drug discovery is expected to grow significantly over the next few years. According to a report by Market Research Future, the market is expected to reach a value of USD 2.7 billion by 2023, with a CAGR of 7.8% during the forecast period (2017-2023).
Factors driving the growth of the market include the increasing prevalence of chronic diseases, such as cancer and diabetes, and the need for more effective and targeted therapies. In addition, advancements in technology, such as high-throughput screening and virtual screening, have facilitated the discovery of new drugs targeting receptors.
The market is segmented by receptor type, therapeutic area, and region. By receptor type, the market is divided into G protein-coupled receptors (GPCRs), ligand-gated ion channels (LGICs), nuclear receptors, and others. GPCRs are the most commonly targeted receptors, as they are involved in a wide range of physiological processes and are the targets of many drugs already on the market.
By therapeutic area, the market is segmented into oncology, neurology, cardiovascular, respiratory, and others. Oncology is the largest segment, accounting for the highest market share due to the high demand for targeted therapies in cancer treatment.
Geographically, North America is the largest market, followed by Europe and Asia-Pacific. The presence of major pharmaceutical companies and research institutions, as well as favorable government initiatives and funding, are driving the growth of the market in North America and Europe.
Overall, the receptor-targeted drug discovery market is expected to continue its growth trajectory in the coming years, driven by advancements in technology and an increasing need for targeted therapies in the treatment of various diseases.
