Chemokines, or chemotactic cytokines, are small cytokines or signaling proteins secreted by cells. They are a component of intercellular communication, controlling the directional movement of immune cells especially leukocytes, as well as other cell types, for instance, endothelial and epithelial cells, which are essential to maintain human health and the function of the immune system.

The biological effects of chemokines are achieved by binding to chemokine receptors, which are G protein-coupled receptors found on the surface of leukocytes. Some chemokine receptors are involved in directing tumor metastasis and over-expression by certain tumors. So inhibiting the interaction between chemokine and chemokine receptors on the surface of tumor cells may be a new possible therapeutic approach. Some chemokine receptors are coreceptors for HIV entry, and related inhibitors have been approved by the FDA to treat patients with HIV. Obviously, chemokines and chemokine receptors have become new targets for studying cancer, HIV, inflammation, and other diseases.

MCE supplies a unique collection of 257 chemokine or chemokine receptor inhibitors and activators, all of which have the identified inhibitory or activated effect on chemokine or chemokine receptors. MCE Chemokine Library is a useful tool for drug research related to cancer, AIDS, and wound therapy.

Liposomes are spherical or multilayered spherical vesicles formed by the self-assembly of diacyl chain phospholipids (lipid bilayers) in aqueous solutions, which can be made from natural or synthetic phospholipids and exhibit good biocompatibility and low toxicity. They can serve as delivery carriers for various bioactive substances (such as drugs, proteins, nucleic acids, etc.) and are widely used in biomedical and chemical research. The main advantages of liposomes include 1) Protective effect: Their bilayer structure can protect encapsulated molecules from enzymatic degradation, oxidation, and other influences, extending stability and activity; 2) Active targeting: Surface modifications enable active targeting, enhancing the concentration of drugs or molecules in specific tissues or cells; 3) Customizability: The composition and structure of liposomes can be adjusted according to needs, such as altering phospholipid types or adding targeting ligands. These properties make liposomes highly valuable in developing novel drug delivery systems, serving as nucleic acid carriers for gene transfection, studying cellular uptake mechanisms and drug release kinetics, as well as developing functional food additives to improve the bioavailability of nutritional components.

MCE contains 227 liposome compounds, which is a good tool for drug delivery-related studies.

Mutations in oncogenes and tumor suppressor genes can modify multiple signaling pathways and in turn cell metabolism, which facilitates tumorigenesis. The paramount hallmark of tumor metabolism is “aerobic glycolysis” or the Warburg effect, coined by Otto Warburg in 1926, in which cancer cells produce most of energy from glycolysis pathway regardless of whether in aerobic or anaerobic condition. Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside. The increased uptake of glucose is facilitated by the overexpression of several isoforms of membrane glucose transporters (GLUTs). Likewise, the metabolic pathways of glutamine, amino acid and fat metabolism are also altered. Recent trends in anti-cancer drug discovery suggests that targeting the altered metabolic pathways of cancer cells result in energy crisis inside the cancer cells and can selectively inhibit cancer cell proliferation by delaying or suppressing tumor growth.

MCE provides a unique collection of 3,806 compounds which cover various tumor metabolism-related signaling pathways. These compounds can be used for anti-cancer metabolism targets identification, validation as well anti-cancer drug discovery.

Copper is an important co-factor of all biological enzymes, but if the concentration exceeds the threshold of maintaining the homeostasis mechanism, copper will lead to cytotoxicity. This death mechanism has been named "Cuproptosis".

The mechanism of cuproptosis distinct from all other known mechanisms of regulated cell death, including apoptosis, pyroptosis, necroptosis, and ferroptosis.

Copper combine with the lipoylated components of the tricarboxylic acid cycle (TCA), leading to lipoylated protein aggregation and subsequent loss of iron-sulfur cluster proteins, ultimately resulting in protein toxicity stress and cell death. Studies have shown that the necessary factors for cuproptosis include the presence of glutathione, mitochondrial metabolism of galactose and pyruvate, and glutamine metabolism.

Targeted regulation of cuproptosis is a potential choice to treat cancer, rheumatoid arthritis, and other diseases. For example, up-regulation of LIPT1 may inhibit the occurrence and development of tumors by destroying TCA in mitochondria and then inducing cuproptosis.

MCE supplies a unique collection of 446 cuproptosis-related compounds, all of which act on the targets or signaling pathways related to cuproptosis and may have in inhibitory or activated effect on cuproptosis. MCE Cuproptosis Library is a useful tool for drug research related to cancer, rheumatoid arthritis, and other diseases.

Cancer

PH11 is a novel focal adhesion kinase (FAK) inhibitor that rapidly induces apoptosis in TRAIL-resistant PANC-1 cells when combined with TRAIL, but has no effect on normal human fibroblasts. The study found that PH11 downregulates c-FLIP through inhibition of FAK and phosphatidylinositol-3-kinase (PI3K)/AKT pathways, thereby restoring the TRAIL apoptotic pathway, suggesting that this combination therapy may provide an attractive therapeutic strategy for the safe and effective treatment of pancreatic cancer. PH11 selectively inhibits c-FLIP expression by modulating upstream signaling pathways and may represent an innovative therapeutic strategy. Although further work is needed to fully elucidate the mechanism of PH11-induced TRAIL sensitization, we believe that our results will provide a new approach to target c-FLIP without the risk of interfering with caspase-8 processing, which could potentially lead to TRAIL resistance. This study also suggests a role for the FAK/AKT signaling pathway in regulating c-FLIP expression in TRAIL-induced apoptosis, and this understanding will provide important clues to control the resistance mechanism to optimize the potential of TRAIL-based pancreatic cancer treatment.

Cancer

(R)-OR-S1 is an isomer of OR-S1. The dual ZH1/2 inhibitors OR-S1 and OR-S2 exhibit strong inhibitory activity against both EZH1 and EZH2. OR-S1 and OR-S2 are highly selective methyltransferase inhibitors against EZH1 and EZH2, and they have very similar molecular features. Therefore, we investigated the effect of OR-S1 on acute myeloid leukemia (AML). We found that OR-S1 was able to induce cell differentiation and apoptosis in AML cells. These findings encouraged us to investigate whether functional LT-HSCs could survive PRC2-targeted therapy with OR-S1 or OR-S1 combined with cytarabine. The results showed that OR-S1 did not cause significant myelosuppression, and BM cells treated with the combination therapy were able to undergo normal hematopoiesis even 4 months after treatment. Therefore, temporary inhibition of EZH1 and EZH2 is clinically tolerable, making this combination therapy suitable for AML patients. AML is generally believed to originate from myeloid progenitor cells that inherit a large number of biological properties.
