1,9-Dimethylmethylene blue is a photosensitizer, virus inactivator and hemoglobin oxidant derived from methylene blue. When activated, 1,9-Dimethylmethylene blue generates reactive oxygen species including singlet oxygen, and acts as a metachromatic dye. When activated in monomeric or dimeric form, 1,9-Dimethylmethylene blue induces photoinactivation of R17 phage and vesicular stomatitis virus and oxidizes hemoglobin via non-singlet oxygen reactive oxygen species or singlet oxygen-mediated pathways, respectively. The monomeric form, with higher nucleic acid affinity, achieves virus inactivation under specific conditions without forming methemoglobin. 1,9-Dimethylmethylene blue binds to substances such as glycosaminoglycans to produce color changes. Although it is susceptible to interference from non-glycosaminoglycan components in urine, it is still applicable to spectrophotometric analysis for glycosaminoglycan quantification. With these unique photochemical and binding properties, 1,9-Dimethylmethylene blue is widely used in studies of viral infections and related biochemical analyses .

626 compounds

Cosmetics are complex mixtures formulated through the rational blending and processing of various natural, synthetic, or extracted raw materials. The ingredients used in cosmetics are diverse in type and functionality. Based on their properties and applications, cosmetic ingredients can generally be classified into two main categories: base materials and auxiliary ingredients. The former constitutes the primary component of cosmetics, accounting for a significant proportion in formulations and serving as the key functional substances. Auxiliary ingredients, on the other hand, play roles in shaping the product, ensuring stability, or imparting color, fragrance, and other specific characteristics.Establishing a systematic ingredient database is of great significance for cosmetic research and development. By analyzing the physicochemical properties (such as oil-water partition coefficients and molecular weight distribution), biological activity mechanisms (such as antioxidant pathways and cellular signaling regulation), and compatibility of ingredients, the database can provide precise guidance for formulation design. This approach helps shorten the development cycle of cosmetic/skincare products and reduces trial-and-error costs.

MCE offers 626 types of cosmetic ingredient compounds, including antioxidants, humectants, emulsifiers, film-forming agents, and more.

Viruses are much simpler organisms than bacteria, and they are made from protein substances and nucleic acid. Despite the fact that the exact mechanism of infection is extremely specific to each type of virus, the general scheme of infection can be represented in the following manner: A virus is absorbed at the surface of a host cell and then permeates through the membrane, where it releases nucleic acid from its protein protection. Then the viral nucleic acid begins to replicate, and transcription of the viral genome takes place either in the cytoplasm, or in the nucleus of the host cell. As a result of these events, a large amount of viral nucleic acid and protein are made to make new generations of virions. Therefore, one mechanism of action of antiviral drugs is to interfere with the ability of a virus to get into a target cell. A second mechanism of action is to target the processes that synthesize virus components after a virus invades a cell, such as nucleotide or nucleoside analogs.

MCE designs a unique collection of 1,237 anti-virus compounds that target several viruses, including SARS-CoV, HBV, HCV, HIV, HSV and Influenza Virus. It’s an effective tool for anti-virus drug discovery.

Macrophages are effector cells of the innate immune system, engulfing bacteria and secreting pro-inflammatory and antibacterial mediators. They are an important component of the first line defense against pathogens and tumor cells. In addition, macrophages play an important role in eliminating damaged cells through programmed cell death. Like all immune cells, macrophages originate from pluripotent hematopoietic stem cells in the bone marrow. Macrophages play key functions in many physiological processes beyond homeostasis and innate immunity, including metabolic function, cell debris clearance, tissue repair, and remodeling. In order to fulfill their different functional roles, macrophages can polarize into a series of phenotypes, including classic (pro inflammatory, M1) and alternative (anti-inflammatory, healing promoting, M2) activation states, as well as a wide range of regulatory phenotypes and subtypes. Macrophages exist in all vertebrate tissues and have a dual function in host protection and tissue damage, maintaining a good balance.

MCE designs a unique collection of 276 macrophage related compounds. It is a good tool to be used for research on Inflammation, cancer and other diseases.

Flavors and fragrances serve as indispensable enhancing elements in modern industries, playing multidimensional roles in the fields of food, cosmetics, and pharmaceutical development. In the food industry, flavors and fragrances are not only used to compensate for flavor loss during processing but also to create novel sensory experiences and enhance product appeal. Natural flavors such as vanilla and citrus oils impart rich, layered aromas to foods, while synthetic flavors can precisely replicate specific tastes, meeting the demands of standardized production and extending the flavor stability of food products. In the cosmetics sector, flavors and fragrances are key to emotional design. They enhance product recognition and elevate the pleasure of use through pleasant scents. In pharmaceutical development, the application of flavors and fragrances focuses on improving compliance. Especially in formulations such as oral liquids and chewable tablets, the addition of mint, fruit, and other flavoring components effectively masks the bitter or irritating taste of medications, increasing patient acceptance. Additionally, some natural flavors may themselves possess auxiliary therapeutic benefits.

MCE contains 495 kinds of flavors and fragrances, which can be used in fields such as food, cosmetics and drug development.

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.
