Autoimmune Disease Compound Library	966 compounds
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). MCE designs a unique collection of 966 autoimmune disease-related compounds, covering multiple targets and subtypes, such as TNF Receptor, IFNAR, JAK, Btk, TLR, IL-6, IL-17, IL-23, etc. It is a useful tool for screening autoimmune disease drugs.

Pattern Recognition Receptors Library	314 compounds
Pattern Recognition Receptors (PRRs) are a crucial class of protein molecules expressed in cells of the innate immune system. The core function of Pattern Recognition Receptors is to recognize Pathogen-Associated Molecular Patterns (PAMPs) and Damage-Associated Molecular Patterns (DAMPs). Upon recognizing and binding to PAMPs or DAMPs, PRRs rapidly initiate intracellular signaling pathways (such as the NF-κB, IRF, and inflammasome pathways). This triggers the production of inflammatory factors, chemokines, and type I interferons, thereby initiating inflammatory responses to eliminate pathogens or repair damage. PRRs represent the body's first line of defense against infection, and the rapidity and broad specificity of their response are crucial for host survival. However, aberrant activation of PRR signaling is also a cause of many chronic inflammatory diseases, autoimmune disorders, and neurodegenerative diseases. Therefore, precisely regulating PRR activity has become a key therapeutic strategy for these conditions. MCE has cataloged 314 inhibitors targeting key PRRs, such as NLRs, TLRs, C-type Lectin Receptors (CLRs), and cGAS, to support drug discovery efforts for chronic inflammatory diseases.
