Coagulation, also known as clotting, is the process in which blood changes from a liquid to a solid gel to form a blood clot. Thrombin, which is accurately and evenly generated in the injured part of blood vessels, is a key effector enzyme of the blood coagulation system and participates in many important biological processes, such as platelet activation, fibrinogen conversion to fibrin network, coagulation feedback amplification, etc. At the same time, to avoid the accidental formation of thrombus in the body, there is also an anticoagulant mechanism that inhibits blood coagulation.
Normal coagulation mechanism represents a balance between the pro-coagulant pathway in the injured site and anti-coagulant pathway beyond it. The blood coagulation system may be out of balance during the perioperative period or critical illness, which may lead to thrombosis or excessive bleeding. Therefore, the physiological study of coagulation balance is an important basis for clinical diagnosis and treatment of the abnormal coagulation process.
MCE supplies a unique collection of 1,525 compounds targeting key proteins in coagulation and anti-coagulation system. MCE Coagulation and Anti-coagulation Compound Library is a useful tool for study the mechanism of coagulation and anticoagulation.

Ion channel is a membrane-binding enzyme whose catalytic site is an ion conduction pore, which is opened and closed in response to specific environmental stimuli (voltage, ligand concentration, membrane tension, temperature, etc.). Ion channel provide pores for the passive diffusion of ions on the biofilm. Due to their high selectivity for ion, ion channel are generally classified as sodium (Na+ ), potassium (K+ ), calcium (Ca2+ ), chloride (Cl- ), and non-specific cation channel. Ion channel is an important contributor to cell signal transduction and homeostasis. In addition to electrical signal transduction, ion channel also have many functions: regulating vascular smooth muscle contraction, maintaining normal cell volume, regulating glandular secretion, protein kinase activation, etc. Therefore, dysfunction of ion channel can lead to many diseases, and its mechanism research is particularly important.

Bile acids are a class of amphiphilic molecules derived from the metabolic breakdown of cholesterol, primarily synthesized in the liver, and play a crucial role in the intestines. Based on their structural characteristics, bile acids are mainly divided into two categories: free bile acids (including Cholic acid, Deoxycholic acid, Chenodeoxycholic acid) and conjugated bile acids (including Glycocholic acid, Glycochenodeoxycholic acid, Taurocholic acid, etc.). Bile acids play a significant role in the pathophysiological research of liver and gastrointestinal diseases and are closely associated with the occurrence of metabolic diseases such as obesity, type II diabetes, non-alcoholic fatty liver disease, and atherosclerosis. Bile acids maintain metabolic balance within the body by regulating sugar metabolism, lipid metabolism, and amino acid metabolism, and they influence the activity of metabolism-related enzymes and transporters. In addition, Bile acids can also be used to construct a bile acid metabolism research platform, which helps to delve into the metabolic pathways and dynamic changes of bile acids in living organisms and aids in identifying new biomarkers for certain diseases.

Copper is an important co-factor of all biological enzymes, but if the concentration exceeds the threshold of maintaining the homeostasis mechanism, copper will lead to cytotoxicity. This death mechanism has been named "Cuproptosis".
The mechanism of cuproptosis distinct from all other known mechanisms of regulated cell death, including apoptosis, pyroptosis, necroptosis, and ferroptosis.
Copper combine with the lipoylated components of the tricarboxylic acid cycle (TCA), leading to lipoylated protein aggregation and subsequent loss of iron-sulfur cluster proteins, ultimately resulting in protein toxicity stress and cell death. Studies have shown that the necessary factors for cuproptosis include the presence of glutathione, mitochondrial metabolism of galactose and pyruvate, and glutamine metabolism.
Targeted regulation of cuproptosis is a potential choice to treat cancer, rheumatoid arthritis, and other diseases. For example, up-regulation of LIPT1 may inhibit the occurrence and development of tumors by destroying TCA in mitochondria and then inducing cuproptosis.
MCE supplies a unique collection of 446 cuproptosis-related compounds, all of which act on the targets or signaling pathways related to cuproptosis and may have in inhibitory or activated effect on cuproptosis. MCE Cuproptosis Library is a useful tool for drug research related to cancer, rheumatoid arthritis, and other diseases.

Lactic acid metabolism is one of the key metabolic pathways within living organisms. It plays a crucial role not only in cellular energy conversion but is also closely related to a variety of physiological and pathological processes. The production and clearance of lactic acid are important indicators of cellular metabolic balance, and its abnormal regulation may lead to conditions such as lactic acidosis, muscle fatigue, and hereditary metabolic diseases. Moreover, lactic acid is closely related to the malignancy of tumors and is considered a biomarker for malignant tumors and poor prognosis. Lactic acid can serve as a metabolic substrate to support the metabolic needs of tumor cells under hypoxic conditions, and it can also cause acidification of the tumor microenvironment, suppress immune cell function to promote immune evasion, and induce drug resistance in tumor cells. Currently, targeting lactic acid-lactylation and its related metabolic pathways has become a new research avenue for cancer treatment. In-depth exploration of the molecular mechanisms of lactic acid metabolism can help in screening lead compounds that regulate the lactic acid metabolism.
MCE contains 582 small molecule compounds targeting enzymes involved in lactic acid metabolism. This library is of significant value for researching the role of lactate metabolism in the mechanisms of diseases.

Unnatural amino acids (UAAs), also referred to as non-canonical amino acids (ncAAs) or non-proteinogenic amino acids, are a class of amino acids that are distinct from the 20 standard natural amino acids. They can be obtained through chemical synthesis, biosynthesis, and other approaches, with structural diversity far exceeding that of natural amino acids. UAAs are mainly including naturally occurring non-canonical amino acids, chemically synthesized amino acids, and biosynthetic amino acids, which provide a molecular basis for protein function design.
UAAs exhibit significant value in multiple fields. They can optimize the pharmacokinetic properties of peptide drugs and peptidomimetics, modify enzyme functions and endow them with new biological activities, thereby overcoming the limitations of traditional peptide drugs and expanding the chemical space . Meanwhile, UAAs can serve as molecular probes to analyze protein-protein interactions and investigate the regulatory mechanisms of protein functions.
MCE has compiled a UAAs Fragment Library comprising nearly a thousand unnatural amino acid fragments with extensive coverage of chemical space and enhanced structural diversity. This compound library can be widely applied in peptide synthesis, drug design, and protein engineering.

Dopamine receptor (DAR), widely distributed in the brain, plays a key role in regulating motor function, motivation, driving force and cognition. The role of DA is mediated by D1-type (D1, D5) and D2-type receptors (D2S, D2L, D3, D4), which are distributed in presynaptic, postsynaptic and extrasynaptic, projection neurons and interneurons. Each receptor has a different function. D1 and D5 receptors couple with G stimulation sites and activate Adenylyl cyclase. The activation of Adenylyl cyclase leads to the production of the second messenger cAMP, which leads to the production of protein kinase A (PKA), which leads to further transcription in the nucleus. D2 to D4 receptors are coupled to G inhibitory sites to inhibit adenylyl cyclase and activate potassium Ion channel. These receptors utilize phosphorylation cascades or direct membrane interactions to affect the functions of voltage-gated and neurotransmitter-gated channels, cytoplasmic enzymes, and transcription factors. Dopamine receptor plays an important role in daily life.
MCE designs a unique collection of 282 small molecules related to dopamine receptor. It is a good tool for screening drugs from nervous system disease.
