administration

An inactive ingredient is any component of a drug product other than the active ingredient. Inactive ingredients are added during the manufacturing process of pharmaceutical products such as tablets, capsules, suppositories, and injections. In new drug development, once an inactive ingredient has appeared in an approved drug product for a particular route of administration, the inactive ingredient is not considered new and may require a less extensive review the next time it is included in a new drug product.

MCE offers a unique collection of 174 inactive ingredients, which only contain inactive ingredients of the final dosage forms of the drug. MCE Inactive Ingredient library is a powerful tool for aiding in the development of the drug and saving unnecessary time.

Natural products are characterized by enormous scaffold diversity and structural complexity, because of which, natural products do show a wide range of biological activities. Medicinal plants have been the major source of medicines over many centuries. About a quarter of all Food and Drug Administration (FDA) and/or the European Medical Agency (EMA) approved drugs are plant based, with well-known drugs such as Paclitaxel and Aspirin having been isolated from plants.

MCE provides a unique collection of 2,929 plant-sourced natural products. MCE Plant-Sourced Natural Product Library is a useful tool for drug discovery that can be used for high throughput screening (HTS) and high content screening (HCS).

Nuclear receptors (NR) are proteins found in cells that sense androgen and thyroid hormones and certain other molecules. They are ligand-activated transcription factors that participate in many aspects of human physiology and pathology, and regulate the expression of various important genes.

Nuclear receptors have become one of the main targets in the development of new drug strategies, providing a unique type of receptors for studying a variety of human diseases, such as breast cancers, skin disorders and diabetes. 13% of U.S. Food and Drug Administration (FDA) approved drugs target nuclear receptors.

MCE supplies a unique collection of 674 nuclear receptor inhibitors and activators, all of which have the identified inhibitory or activated effect on nuclear receptor. MCE Nuclear Receptor Library is a useful tool for drugs research related to cancer, skin disease and diabetes.

Most of the drugs that are available in the marketplace are administered via the oral route, which is a convenient and cost effective route of administration. Thus, oral bioavailability is one of the key considerations in drug design and development. A high oral bioavailability reduces the amount of an administered drug necessary to achieve a desired pharmacological effect and therefore could reduce the risk of side-effects and toxicity. A poor oral bioavailability can result in low efficacy and higher inter-individual variability and therefore can lead to unpredictable response to a drug. Low oral bioavailability in clinical trials is a major reason for drug candidates failing to reach the market.

MCE offers a unique collection of 3,666 compounds with confirmed high oral bioavailability. MCE Orally Active Compound Library is a useful tool for discovering new drugs with oral bioavailability.

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 136 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.

From target identification to clinical research, traditional drug discovery and development is a time-consuming and costly process, which also bears high risk. Compared with traditional drug discovery, drug repositioning or repurposing, also known as old drugs for new uses can greatly shorten the development cycle and reduce development cost, which has become a new trend of drug development. After undergoing clinical trials, approved drugs have identified bioactivities, good pharmacokinetic characteristics and safety, which can greatly improve the success rate of drug discovery. A number of successes have been achieved, such as metformin for type 2 diabetes and thalidomide for leprosy and multiple myeloma, etc.

MCE provides a unique collection of 1,412 China NMPA (National Medical Products Administration) approved compounds, which have undergone extensive preclinical and clinical studies and have well-characterized bioactivities, safety and bioavailability properties. MCE NMPA-Approved Drug Library is a good tool for drug repurposing which could dramatically accelerate drug development.
