channel activity

Membrane receptors, also known cell surface receptors or transmembrane receptors, are transmembrane proteins embedded into the plasma membrane which play an essential role in maintaining communication between the internal processes within the cell and various types of extracellular signals. They act in cell signaling by receiving (binding to) extracellular molecules, which are also called ligands. These extracellular molecules include hormones, cytokines, growth factors, neurotransmitters, lipophilic signaling molecules such as prostaglandins, and cell recognition molecules.

There are three kinds of membrane receptors: ion channel-linked receptors, enzyme-linked receptors and G-protein-linked receptors. They play important roles in keeping human normal physiologic processes. GPCRs and ion channels are important drug targets in drug discovery.

MCE provides a unique collection of 4,892 compounds targeting a variety of membrane receptors. MCE Membrane reeptor-targeted Compound Library can be used for membrane receptor-focused screening and drug discovery.

Neurodegenerative diseases are characterised by progressive dysfunction and death of neurons, such as Alzheimer’s disease, Parkinson’s disease, and multiple sclerosis (MS). Neuroprotection is an approach to preserve neurons so that neurons cannot be hurt by different pathological factors in neurodegenerative diseases. Neuroprotectors are some agonists and antagonists targeting some key targets in neuroprotactive signal pathways, such as calcium and sodium channel blockers, GABA receptor agonists, NMDA receptor Antagonists, etc. Current neuroprotectors cannot reverse existing damage, but they may protect against further nerve damage and slow down any degeneration of the central nervous system (CNS) and still play important roles in the treatment of neurodegenerative diseases.

MCE offers a unique collection of 1,133 compounds with potential neuroprotective activities. These compounds mainly act on some key targets in neuroprotetive signal pathways, such as calcium channel, sodium channel, adenosine A1 receptor, etc. MCE Neuroprotective Compopund Library is a useful tool in neuroprotective drug discovery.

A membrane protein is a protein molecule that is attached to or associated with the membrane of a cell or an organelle. Membrane proteins can be classified into two groups based on how the protein is associated with the membrane: integral membrane proteins and peripheral membrane proteins. In humans, about 30% genome encodes membrane proteins. Membrane proteins perform a variety of functions vital to the survival of organisms, for example, signal transduction, molecules or ion transportation, enzymatic catalysis, and intercellular communication. Membrane proteins also play important roles in drug discovery. As reported, more than 60% of current drug targets are membrane proteins.

MCE supplies a unique collection of 7,194 compounds targeting a variety of membrane proteins. MCE Membrane Protein-targeted Compound Library can be used for membrane protein-focused screening and drug discovery.

Agonistic drugs activate or stimulate their receptors, triggering responses that increase or decrease cell activity. The highly selective activators can act on specific biological or molecular targets, while non-selective activators may interfere with multiple targets or targets simultaneously. The highly selective activators reduce the likelihood of these non-specific effects by targeting specific targets, making research more precise and reliable. The Highly Selective Activators Library contains 1,510 compounds, covering multiple targets and subtypes, such as GPCR protein family, Ion channel, multiple kinases, etc. The Highly Selective Activators Library is an effective tool for screening different phenotypes.

Cardiovascular diseases (CVDs) are a group of disorders of the heart and blood vessels which include coronary heart disease, cerebrovascular disease, peripheral arterial disease, rheumatic heart disease, etc. CVDs are the number 1 cause of death globally. Smoking, unhealthy nutrition, aging population, lack of physical activity, arterial hypertension, or diabetes can promote cardiovascular disease like myocardial infarction or stroke. It is multifactorial and encompasses a multitude of mechanisms, such as eNOS uncoupling, reactive oxygen species formation, chronic inflammatory disorders and abnormal calcium homeostasis. Antioxidant, anti-inflammatory and anti-diabetes agents may reduce the cardiovascular disease risk.

MCE supplies a unique collection of 1,669 compounds with confirmed anti-cardiovascular activity. These compounds mainly target metabolic enzyme, membrane transporter, ion channel, inflammation related signaling pathways. MCE Anti-Cardiovascular Disease Compound Library can be used for cardiovascular diseases related research and high throughput and high content screening for new drugs.

The majority of hypertensive patients have primary (or essential) hypertension, that is, hypertension in which secondary causes are not present. Management aims to control arterial pressure, prevent end-organ damage (cerebrovascular, cardiovascular, and renal), and reduce the risk of premature death.

Antihypertensive drugs may be divided into two broad groups, the first group being those which directly or indirectly block the renin–angiotensin system (RAS), for example, ACEIs, angiotensin receptor antagonists (ARAs), direct renin inhibitors (DRIs), and to a lesser extent β-blockers. The second group of drugs works by increasing water and sodium excretion, thereby reducing intravascular volume, or by causing vasodilatation through non-RAS pathways, for example, diuretics and calcium channel blockers (CCBs).

MCE offers a unique collection of 639 compounds with identified and potential antihypertensive activity. MCE Antihypertensive Compound Library is critical for antihypertensive drug discovery and development.
