Anti-Brain Cancer Compound Library

2,056 compounds

Although brain cancer only accounts for 2% of all tumors, it has a poor prognosis, high mortality and high recurrence rate. Brain cancer can be divided into primary brain cancer and secondary brain cancer. According to the location of the cancer, brain cancer can also be divided into: brain glioma, pituitary adenoma, schwannoma, craniopharyngioma, meningioma and so on. Glioma is the most common primary brain tumor, accounting for about 1/3 of all brain tumors. At present, brain cancer lacks precision targeted therapeutic drugs, and there is still a great clinical demand that has not been met. With the continuous development of high-throughput screening technology, it may be able to help develop effective anti-brain cancer drugs by screening compounds targeting PKC, PD-1, c-Met, PARP, etc targets.

MCE designs a unique collection of 2,056 small molecules with definite or potential anti-brain cancer activity, which is an important tool for studying the pathological mechanism of brain cancer and developing drugs for brain cancer.

Small Molecule Immuno-Oncology Compound Library

783 compounds

Immuno-Oncology is a type of immunotherapy that has the specific purpose of treating cancer. It works by stimulating our immune system to fight back. Normally, our immune system is able to destroy cancer cells in our body, however sometimes cancer cells can adapt and mutate, effectively hiding from our immune system. This is when tumors can develop and become a threat to our health. Immuno-oncology involves mobilizing lymphocytes to recognize and eliminate cancer cells using the body’s immune system. There are several immuno-oncology treatments available, including Immune cell therapy (CAR-T), monoclonal antibodies (mABs) and checkpoint inhibitors, cytokines and cancer vaccines.

MCE Small Molecule Immuno-Oncology Compound Library offers 783 bioactive tumor immunology compounds that target some important checkpoints such as PD1/PD-L1, CXCR, Sting, IDO, TLR, etc. This library is a useful tool for Immuno-oncology research.

Anti-Gastric Cancer Compound Library

1,122 compounds

Gastric Cancer (GC) is one of the most common malignant tumors in the world, ranking fourth in mortality rate globally. Because the early symptoms of stomach neoplasm are usually not obvious, are diagnosed with gastric cancer at terminal stage, and the relative survival rate within 5 years is very low. With the further understanding of the molecular characteristics of stomach neoplasm, many therapeutic targets for gastric cancer have been identified, and molecular targeted therapies such as CTLA-4, HER2 and immune checkpoint inhibitors have made rapid progress. Although survival rates for patients with gastric neoplasm have improved over the past few decades, the prognosis is still worrying. Therefore, there is an urgent need for new drugs to treat gastric cancer.

MCE designs a unique collection of 1,122 small molecules with definite or potential anti-gastric cancer activity, which is an important tool for studying the pathological mechanism of stomach neoplasm and developing drugs for stomach neoplasm.

Anti-Blood Cancer Compound Library

4,121 compounds

Blood cancers, also called hematologic cancers, occur when abnormal blood cells start growing out of control, interrupting the function of normal blood cells, which fight off infection and produce new blood cells. Most blood cancers start in the bone marrow, which is where blood is produced. There are three main types of blood cancers: leukemia, lymphoma and myeloma, which afflict millions of children and adults every year, and are often deadly.

Some common blood cancer treatments include stem cell transplantation, chemotherapy, radiation therapy, targeted therapy, immunotherapy or a combination thereof. As we begin to understand the key signaling pathways and molecular drivers of malignant transformation in haematological disorders, new treatment strategies will continue to be developed.

MCE offers a unique collection of 4,121 compounds with identified and potential anti-blood cancer activity. These compounds target blood cancer’s major targets and signaling pathways. MCE anti-blood cancer compound library is a useful tool for anti-blood cancer drugs screening and other related research.

Immunology/Inflammation Compound Library

7,846 compounds

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 7,846 compounds that are useful tool for Immunology/Inflammation research or autoimmune inflammatory diseases drug discovery.

Protein-protein Interaction Inhibitor Library

782 compounds

Protein protein interactions (PPI) have pivotal roles in life processes. The studies showed that aberrant PPI are associated with various diseases, including cancer, infectious diseases, and neurodegenerative diseases. The classic drug targets are usually enzymes, ion channels, or receptors, the PPI indicate new potential therapeutic targets. Therefore, targeting PPI is a new direction in treating diseases and an essential strategy for the development of new drugs.

However, the design of modulators targeting PPI still faces tremendous challenges, such the difficult PPI interfaces for the drug design, lack of ligands reference, lack of guidance rules for the PPI modulators development and high-resolution PPI proteins structures.

With the development of high-throughput technology, high-throughput screening is also gradually used for the identification of PPI inhibitors, but the compound library used for conventional target screening is not very effective in screening PPI inhibitors. To improve screening efficiency, MCE carefully selected 782 PPI inhibitors and mainly targeting MDM2-p53, Keap1-Nrf2, PD-1/PD-L1, Myc-Max, etc. MCE Protein-protein Interaction Inhibitor Library is a useful tool for PPI drug discovery and related research.
