resources

At the forefront of innovative drug discovery, every medicinal chemist faces the challenge of rapidly identifying high-quality hit compounds from vast repositories of chemical resources.

The MCE Natural Product Diversity Scaffold Library is the result of a streamlined optimization process built upon our existing natural product collection. Adhering to the rigorous selection principle of "retaining only one representative compound per BMS scaffold", we have concentrated the diversity of thousands of compounds into a high-value, low-redundancy core set containing 2,260 compounds. All compounds are derived from natural sources, inheriting their inherent advantages of structural complexity and drug-likeness. By eliminating redundancy, the library size is significantly reduced without any compromise to chemical diversity. This approach effectively lowers the cost and time required for primary screening while simplifying downstream data analysis and structure-activity relationship (SAR) studies.

Tibetan medicine, as one of the treasures of traditional Chinese medicine, carries the profound cultural heritage of the Tibetan people and their unique understanding of health. Tibet is the birthplace of Tibetan medicine, and its plateau climate and unique ecological environment have nurtured its rich medicinal resources. Among them, cordyceps, saffron and snow lily are favored by people for their excellent medicinal value and unique growth characteristics. Tibetan medicine, with its profound heritage, plays a crucial role in the management of diseases that are unique to high-altitude regions, such as altitude stress. It facilitates a swifter adaptation to high-altitude conditions and mitigates the symptoms of altitude sickness by meticulously recalibrating the internal environment within the human body. For rheumatic diseases, cardiovascular diseases, etc., Tibetan medicine has also shown its remarkable effect.

MCE included 1,132 natural products from Tibetan medicine, including animal, plant and mineral sources.

Miao medicine is an important part of Chinese medicine, which carries the profound cultural heritage and rich life wisdom of the Hmongb people. Miao people live in a concentrated community in the mountainous area of the southwest border of China, which has a unique natural environment. Complex and diverse geology, lush natural vegetation, rich animal and plant species, a large number of mineral resources which provide a wide range of species sources for miao ethnicity medicine. On the other hand, due to the characteristics of the living environment of the Hmongb people, Miao medicine has demonstrated its unique therapeutic effect in the treatment of some endemic diseases, infectious diseases, insect, snake and beast bites, rheumatism and other diseases. With the development of modern science and technology, the research and application of seedling medicine are also deepening. Through the systematic study of the chemical composition and pharmacological action of the seedling medicine, it can provide a new idea and method for modern medicine.

MCE included 1,631 natural products from traditional miao ethnicity medicine, including animal, plant and mineral sources.

Traditional Chinese medicine provides abundant natural resources for medicinal compounds, which are often considered effective and safe for drug discovery. Traditional Chinese medicine is based on the principle of "multiple components, multiple targets, and multiple pathways", and naturally has multiple pharmacological effects. As herbal medicine, the secondary plant metabolites in Chinese herbal medicine play an important role in alleviating many diseases in Traditional medicine and folk use. Therefore, the identification of traditional Chinese medicine derived compounds is also an important process in drug development and a necessary factor in dissecting the overall mechanism of action of traditional Chinese medicine. FDA listed compounds have completed extensive preclinical and clinical studies, exhibiting good biological activity, safety, and bioavailability.

MCE designs a unique collection of 305 FDA/EMA/NMPA/PMDA etc-approved traditional Chinese medicine active compounds, including flavonoids, polyphenols, alkaloids, terpenoids, and other structural types. It is a good tool for drug reuse and screening drugs from traditional Chinese medicine sources.

In the progression of various diseases, metabolic reprogramming has emerged as a key hallmark. Lactate, as an important metabolic signaling molecule, is widely involved in tumorigenesis, immune regulation, and inflammatory responses. Particularly within the tumor microenvironment, the abnormal accumulation of lactate not only affects cellular energy metabolism but also promotes disease progression by modulating immune cell functions and mediating protein lactylation, thereby participating in epigenetic regulation and signaling networks. Therefore, systematic investigation of lactate metabolic pathways and their associated metabolites is of great significance for understanding disease mechanisms and developing novel therapeutic strategies.

The MCE lactic acid metabolite compound library contains 61 compounds and is constructed around key metabolic pathways involving lactate production, transport, and utilization. This library systematically includes core intermediates from glycolysis, the tricarboxylic acid (TCA) cycle, and the lactate cycle. Focusing on disease-associated metabolic reprogramming, it is suitable for research in oncology, inflammation, and metabolic disorders. The library can be used to elucidate the roles of lactate in tumor microenvironment regulation, immune evasion, and epigenetic modifications (such as protein lactylation). In addition, it provides high-quality small-molecule resources for drug screening, facilitating the discovery of potential modulators targeting key enzymes (such as LDH) or transporters (such as MCTs) involved in lactate metabolism.
