Lipopolysaccharides, from S. enterica serotype minnesota LPS, from Salmonella enterica (Serotype minnesota)	Toll-like Receptor (TLR)	Inflammation/Immunology
Lipopolysaccharides (LPS) are specific endotoxins and one of the major components of the cell wall of Gram-negative bacteria. Lipopolysaccharides consist of three parts: lipid A, core oligosaccharide, and O-specific polysaccharide. Lipopolysaccharides are powerful immune stimulants that can activate the host immune system, particularly by binding to Toll-like receptor 4 (TLR4) on the surface of immune cells, triggering an inflammatory response. The LPS of most Salmonella serotypes has a complex O-antigen (OAg) structure, with the number of OAg units in the core polysaccharide varying between 16 and over 100 repeats. Mutations in OAg-regulating factors that alter the OAg structure can change the interaction between Salmonella and epithelial cells. Strains with long OAg have increased SPI1-T3SS effector protein translocation and invasion. Strains completely lacking OAg exhibit increased invasiveness and higher adhesiveness. This product is derived from Salmonella enterica serotype Minnesota. Lipopolysaccharides, from S. enterica serotype minnesota, can be used to study host immune system activation and its role in inflammation and immune regulation .

Endoplasmic Reticulum Stress Compound Library	235 compounds
Endoplasmic reticulum (ER) contributes to the production and folding of approximately one third of cellular proteins, and is thus inextricably linked to the maintenance of cellular homeostasis and the fine balance between health and disease. However, some adverse factors negatively impact ER functions and protein synthesis, resulting in the activation of Endoplasmic reticulum stress (ER stress, ERS) and unfolded protein response (UPR) signaling pathways. The UPR is triggered when ER protein folding capacity is overwhelmed by cellular demand and the UPR initially aims to restore ER homeostasis and normal cellular functions. However, if this fails, then the UPR triggers cell death. Chronic ER stress and defects in UPR signaling are emerging as key contributors to a growing list of human diseases, including diabetes, neurodegeneration and cancer. MCE Endoplasmic Reticulum Stress Compound Library contains 235 ER stress-related compounds that mainly target PERK, IRE1, ATF6, etc. MCE ER stress library is a useful tool for researching ER stress and related diseases.

Anti-Breast Cancer Compound Library	2,238 compounds
Breast cancer is the most frequent cancer among women, impacting 2.1 million women each year, and also causes the greatest number of cancer-related deaths among women. Surgery is usually the first type of treatment for breast cancer, which is usually followed by chemotherapy or radiotherapy or, in some cases, hormone or targeted therapies, especially for metastatic breast cancer (MBC). Breast cancer is a heterogeneous disease, which is categorized into 3 major subtypes based on the presence or absence of molecular markers for estrogen or progesterone receptors and human epidermal growth factor 2 (ERBB2; formerly HER2): hormone receptor positive/ERBB2 negative (70% of patients), ERBB2 positive (15%-20%), and triple-negative (tumors lacking all 3 standard molecular markers; 15%). Different intrinsic subtypes exhibit different tumor behavior with different prognoses, and may require specific targeted therapies to maximize treatment effectiveness. Otherwise, some signaling pathways also play important roles in the development of breast cancer, such as NF-κB Signaling Pathway, TGF-beta Signaling Pathway, PI3K/AKT/mTOR signaling pathway and Notch Signaling Pathway. These signaling pathways offer ideal targets for development of new targeted therapies for breast cancer. MCE supplies a unique collection of 2,238 compounds with identified and potential anti-breast cancer activity. MCE Anti-Breast Cancer Compound Library is a useful tool for anti-breast cancer drugs screening.
