Environmental pollution refers to the process where human activities release harmful chemicals or energy (such as industrial waste, pesticides, and plastic particles) into the natural environment at a rate that exceeds the ecosystem's capacity for self-purification, leading to deterioration in the composition or state of the atmosphere, water bodies, and soil. Environmental pollution is not only a direct threat to biodiversity but also ultimately impacts human health through the bioaccumulation effect of the food chain. Therefore, the accurate identification and dynamic monitoring of pollutants constitute the scientific cornerstone for formulating environmental policies, assessing ecological risks, and promoting green chemistry transformation.

MCE features a collection of 869 environmental pollutants, covering categories such as air pollutants, water pollutants, and pesticides, for research in the field of environmental chemistry.

Vitamins are a category of trace organic compounds essential for maintaining normal physiological functions in living organisms. They are classified into fat-soluble and water-soluble vitamins. Fat-soluble vitamins play a role in maintaining vision, bone health, reproductive functions, and blood coagulation. Water-soluble vitamins are involved in energy metabolism, nervous system function, and cellular repair processes. Most vitamins cannot be synthesized by the organism and must be obtained through diet. In recent years, vitamins and their derivatives have become increasingly important in the field of drug development due to their extensive physiological activities. Additionally, vitamins and their derivatives can be used to construct research platforms for vitamin metabolism, which helps to delve into the metabolic pathways and dynamic changes of vitamins within the body and aids in identifying new biomarkers for certain diseases.

MCE included 135 vitamins and their derivatives, including Vitamin A, Vitamin B, Vitamin D, etc., which is a good tool for studying vitamin metabolism.

A parasite is an organism that lives on or in a host organism and gets its food from or at the expense of its host. Parasites of humans include protozoans, helminths, and ecto-parasites (organisms that live on the external surface of a host). They are responsible for many diseases and are transmitted to their hosts most often through the ingestion of contaminated food, water or through the bite of an arthropod (e.g., a fly or tick), which can act as an intermediate host and as a vector. Parasitic diseases of humans are a major global health problem causing significant morbidity and mortality, especially in developing countries. Each year there are hundreds of millions of people infected with disease-causing parasites, particularly in tropical and subtropical regions of the world, resulting in an estimated one million deaths. Therefore, there is a dire need of novel anti-parasitic drugs.

MCE has a unique collection of 649 compounds with validated anti-parasitic activity which offer researchers an opportunity to screen novel anti-parasitic targets.

Cancer is a multi-step process which involves initiation, promotion and progression. Chemical carcinogens can alter any of these processes to induce their carcinogenic effects. People are continuously exposed exogenously to varying amounts of chemicals that have been shown to have carcinogenic or mutagenic properties in experimental systems. Exposure can occur exogenously when these agents are present in food, air or water, and also endogenously when they are products of metabolism or pathophysiologic states such as inflammation. The administration of chemical carcinogens is one of the most commonly used methods to induce tumors in several organs in laboratory animals in order to study oncologic diseases of humans. MCE offers a unique collection of 144 chemical carcinogens which have been identified with carcinogenic activity either in humans or in animal models. MCE Tumorigenesis-Related Compound Library is a powerful tool for studying oncologic diseases of humans. Standard opration based on safety data sheet will not cause harm to the body.

The majority of hypertensive patients have primary (or essential) hypertension, that is, hypertension in which secondary causes are not present. Management aims to control arterial pressure, prevent end-organ damage (cerebrovascular, cardiovascular, and renal), and reduce the risk of premature death.

Antihypertensive drugs may be divided into two broad groups, the first group being those which directly or indirectly block the renin–angiotensin system (RAS), for example, ACEIs, angiotensin receptor antagonists (ARAs), direct renin inhibitors (DRIs), and to a lesser extent β-blockers. The second group of drugs works by increasing water and sodium excretion, thereby reducing intravascular volume, or by causing vasodilatation through non-RAS pathways, for example, diuretics and calcium channel blockers (CCBs).

MCE offers a unique collection of 900 compounds with identified and potential antihypertensive activity. MCE Antihypertensive Compound Library is critical for antihypertensive drug discovery and development.

Diarrhea is a disease symptom, and the pathophysiologic basis of diarrhea is a disturbance in intestinal water and electrolyte balance, which may be due to increased secretion of osmotically active electrolytes (secretory diarrhea) or increased intake of osmotically active substances (osmotic diarrhea). Food poisoning, pathogenic bacterial infections, and intestinal-related diseases can all contribute to the development of diarrhea. Traditional Chinese Medicine (TCM) considers diarrhea to be a symptom of an imbalance in the body's systems, particularly related to the functions of the spleen and stomach. Spleen qi deficiency, dampness-heat, liver and spleen disharmony are closely related to diarrhea. Many types of Chinese herbs regulate the function of diarrhea, such as: Dysosmae Verspiellis Rhixoma Et Radix, Ginkgo Semen, Forsythiae Fructus, and Campsis Flos.

MCE can provide 2,465 active monomers that can be obtained from TCM herbs with diarrhea-regulating functions, which can be applied to drug development and disease mechanism research.

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