Cell Cycle/DNA Damage Compound Library	2,071 compounds
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 2,071 cell cycle/DNA damage-related compounds which can be used in the research of the same.

Anti-Fibrosis Compound Library	863 compounds
Fibrosis is a kind of repair response to long-term tissue damage, which is mainly manifested by excessive deposition of extracellular matrix (ECM) and scar formation. Myofibroblasts are the main generating cells of extracellular matrix, and their activation process is related to various pathological mechanisms including Oxidative stress, chronic inflammation and cytokine secretion. Fibrosis can occur in many organs, such as kidneys, liver, heart, lungs, etc. Continuous fibrosis can lead to the destruction of the normal structure of tissues and organs, and if not controlled in time, may cause organ failure or even life-threatening. MCE contains 863 compounds targeting ant-fibrosis targets such as TGF-β, PI3K, Wnt, MMP, etc. These compounds have clear or potential anti-fibrosis activity and can be used for mechanism research and drug screening of fibrosis diseases.

Antibiotics Library	659 compounds
Antibiotics are types of antimicrobial products used for the treatment and prevention of bacterial infections. Antibiotics can kill or inhibit bacterial growth. Although the target of an antibiotic is bacteria, some antibiotics also attack fungi and protozoans. However, antibiotics rarely have an effect on viruses. The major mechanism underlying antibiotics is the inhibition or regulation of enzymes involved in cell wall biosynthesis, nucleic acid metabolism and repair, protein synthesis, or disruption of membrane structure. Many of these cellular functions targeted by antibiotics are most active in multiplying cells. Since there is often overlap in these functions between prokaryotic bacterial cells and eukaryotic mammalian cells, it is not surprising that some antibiotics have also been found to be useful as anticancer agents. MCE supplies a unique collection of 659 antibiotics, including penicillins, cephalosporins, tetracyclines, macrolides, etc. MCE Antibiotics Library is a useful tool for anti-bacterial or anti-cancer drugs discovery.
