Cytokines are a kind of low molecular soluble proteins synthesized and secreted by immunogen, mitogen or other factors. They have functions of regulating innate and adaptive immune responses, promoting hematopoiesis, stimulating cell activation, proliferation and differentiation. The process of releasing a large number of cytokines is also called “Cytokine storm”, which can cause damage to many tissues and organs in the body. Cytokine is involved in the pathogenesis of many human diseases, including cancer, diabetes, chronic inflammatory diseases and so on. Cytokine inhibitors are a class of essential compounds that act by directly inhibiting the synthesis and release of cytokine or blocking the binding of cytokine to their receptors. Cytokine inhibitors are important compounds for the study of tumor and autoimmune diseases.

Autoimmune disease is a pathological disease characterized by inflammatory disorders targeting autoantigens. The routine treatment of autoimmune diseases suppresses general immune function to regulate uncontrolled inflammation. The current targeted immunotherapy suppresses the main pro-inflammatory signaling pathways by blocking inflammatory cytokines, cell surface molecules, and intracellular kinases. As key participants in innate immunity, macrophages and dendritic cells (DCs) are crucial for Ag presentation and pro-inflammatory cytokine production, such as TNF and IL-1 β、 IL-6, IL-23, B cell activating factor (BAFF), and the proliferation-inducing ligand (APRIL, also known as TNFSF13A).

Inflammasomes are classic pattern recognition receptors for natural immune responses. Inflammasomes are polymeric protein complexes that regulate inflammatory responses and pyrolytic cell death, thereby exerting the host's defense against microorganisms. Inflammasomes sensors are associated with adapter proteins, activating inflammatory caspase-1, releasing inflammatory cytokines and inducing cell death, endowing the host with defense against pathogens. NLRP1, NLRP3, NLRC4, AIM2, and pyrin are considered typical inflammasomes because they convert cysteine asparaginase-1 into catalytically active capsaicin-1. In addition to infectious diseases, the importance of inflammasomes is also related to various clinical diseases, such as autoimmune diseases, neurodegeneration and metabolic disorders, and the development of cancer. Therefore, it is necessary to strictly regulate the activation and function of inflammasomes to avoid accidental host tissue damage while inducing pathogens to kill the inflammatory response.

The immune system is a host defense system comprising many biological structures and processes within an organism that protects against disease. To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism's own healthy tissue. Inflammation is also the body's attempt at self-protection to remove harmful stimuli and begin the healing process. It’s part of the body's immune response. The immune system recognizes damaged cells, irritants, and pathogens, and inflammation begins the healing process. Inflammatory abnormalities are a large group of disorders that underlie a vast variety of human diseases. The immune system is often involved with inflammatory disorders, demonstrated in both allergic reactions and some myopathies, with many immune system disorders resulting in abnormal inflammation.

MCE designs a unique collection of 6,825 compounds that are useful tool for Immunology/Inflammation research or autoimmune inflammatory diseases drug discovery.

Programmed cell death pathways, including apoptosis, pyroptosis and necroptosis, are regulated by unique sets of host proteins that coordinate a variety of biological outcomes. Pyroptosis is a highly inflammatory form of programmed cell death that occurs most frequently upon infection with intracellular pathogens and is likely to form part of the antimicrobial response. This process promotes the rapid clearance of various bacterial, viral, fungal and protozoan infections by removing intracellular replication niches and enhancing the host's defensive responses. Pyroptosis has been widely studied in inflammatory and infection disease models. Recently, there are growing evidences that pyroptosis also plays an important role in the development of cancer, cardiovascular diseases and Metabolic disorder, etc.

Macrophages are effector cells of the innate immune system, engulfing bacteria and secreting pro-inflammatory and antibacterial mediators. They are an important component of the first line defense against pathogens and tumor cells. In addition, macrophages play an important role in eliminating damaged cells through programmed cell death. Like all immune cells, macrophages originate from pluripotent hematopoietic stem cells in the bone marrow. Macrophages play key functions in many physiological processes beyond homeostasis and innate immunity, including metabolic function, cell debris clearance, tissue repair, and remodeling. In order to fulfill their different functional roles, macrophages can polarize into a series of phenotypes, including classic (pro inflammatory, M1) and alternative (anti-inflammatory, healing promoting, M2) activation states, as well as a wide range of regulatory phenotypes and subtypes. Macrophages exist in all vertebrate tissues and have a dual function in host protection and tissue damage, maintaining a good balance.

Pain is a kind of distressing feeling caused by the stimulation of tissue damage. According to the International Association for the Study of Pain (IASP), pain is defined as ”An unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage”.

Pain is usually classified according to its location, duration, underlying causes, and intensity. For example, acute and chronic pain, muscle pain, and nerve pain. Pain is the main symptom of most diseases, which seriously affects the quality of life and body function of patients. In the medical treatment of pain, anti-inflammatory drugs and opioid analgesic agents have traditionally been used, but the side effects are serious. In recent years, targeted drugs targeting the ERK/MAPK pathway or other targets have gradually become a research hotspot.

MCE supplies a unique collection of 2,788 compounds targeting key proteins in the pain system. MCE Pain-Related Compound Library is a useful tool for pain related research and anti-pain drug development.

DNA is prone to numerous forms of damage that can injure cells and impair fitness. Cells have developed an array of mechanisms to repair these injuries. Proliferating cells are especially vulnerable to DNA damage due to the added demands of cellular growth and division. Cell cycle checkpoints represent integral components of DNA repair that coordinate cooperation between the machinery of the cell cycle and several biochemical pathways that respond to damage and restore DNA structure. By delaying progression through the cell cycle, checkpoints provide more time for repair before the critical phases of DNA replication, when the genome is replicated, and of mitosis, when the genome is segregated. Loss or attenuation of checkpoint function may increase spontaneous and induced gene mutations and chromosomal aberrations by reducing the efficiency of DNA repair.

MCE owns a unique collection of 2,874 cell cycle/DNA damage-related compounds which can be used in the research of the same.
