3,003 compounds

Liver cancer is one of the leading malignancies which occupies the second position in cancer deaths worldwide, becoming serious threat to human health. Hepatocellular carcinoma (HCC), also known as hepatoma is the most common type accounting for approximately 90% of all liver cancers.

Current evidence indicates that during hepatocarcinogenesis, two main pathogenic mechanisms prevail: (1) cirrhosis associated with hepatic regeneration after tissue damage caused by hepatitis infection, toxins or metabolic influences, and (2) mutations occurring in single or multiple oncogenes or tumor suppressor genes. Both mechanisms have been linked with alterations in several important cellular signaling pathways. These include the RAF/MEK/ERK pathway, PI3K/AKT/mTOR pathway, WNT/b-catenin pathway, insulin-like growth factor pathway, c-MET/HGFR pathway , etc.

MCE offers a unique collection of 3,003 compounds with identified and potential anti-liver cancer activity. MCE anti-liver cancer compound library is a useful tool for anti-liver cancer drugs screening and other related research.

Aging is a complex biological process characterized by functional decline of tissues and organs, structural degeneration, and reduced adaptability and resistance, all of which contribute to an increase in morbidity and mortality caused by multiple chronic diseases, such as Alzheimer's disease, cancer, and diabetes. Many theories, which fall into two main categories: programmed and error theories, have been proposed to explain the process of aging, but neither of them appears to be fully satisfactory. The programmed theories imply that aging relies on specific gene regulation, and the error theories emphasize the internal and environmental damages accumulated to living organisms. The damage theories proposed the nine hallmarks that were generally considered to contribute to the aging process: genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis, deregulated nutrient-sensing, mitochondrial dysfunction, cellular senescence, stem cell exhaustion, and altered intercellular communication.

MCE Anti-Aging Compound Library contains 7,771 compounds, mainly targeting Sirtuin, mTOR, IGF-1R, AMPK, p53, Telomerase, Mitophagy, Mitochondrial Metabolism, COX, Cytochrome P450, Oxidase, etc. This library is a useful tool for anti-aging research.

P53/TLR2 modulator-1 (Compound Z9) is a modulator that targets both the P53 pathway and TLR2 simultaneously, exhibiting anti-radiation activity. P53/TLR2 modulator-1 reduces apoptosis by inhibiting the radiation-induced expression of P53 and Bax. At the same time, it activates the TLR2 pathway, upregulates the expression of downstream proteins MyD88 and P65, and promotes the secretion of cytokines such as IL-6, thus exerting an anti-radiation effect. P53/TLR2 modulator-1 shows significant anti-radiation activity against both AHH-1 cells and HUVECs. It can also increase the survival rate of C57BL/6J mice irradiated with a lethal dose of radiation and reduce the damage to their hematopoietic system, the villous structure of the small intestine, and the spleen caused by radiation. P53/TLR2 modulator-1 can be used in the research of radiation injury-related diseases .
