2,256 compounds

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 2,256 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.

1,237 compounds

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.

2,787 compounds

Seven-membered rings are privileged medium-sized scaffolds with distinct twist-chair conformations and greater 3D diversity than five- and six-membered rings. Their flexible conformations allow induced-fit protein binding and precise pharmacophore positioning. They also modulate Fsp³, pKa and logP to enhance solubility and permeability. Azepanes, oxepanes and benzodiazepines serve as bioisosteres for hit discovery against GPCRs, ion channels and kinases.

Widely found in plant and microbial alkaloids, seven-membered heterocycles show excellent biocompatibility and target affinity. They underpin many approved drugs for CNS, cancer and infectious diseases, including diazepam, imipramine and carbamazepine. Clinical candidates further highlight their unique value. However, high transannular strain and synthetic difficulty limit their availability, leaving them rare in standard screening libraries.

MCE 7 Membered Scaffold Library contains 2,792 structurally diverse, lead-like molecules covering azepanes, oxepanes, benzodiazepines and dibenzazepines. With varied substitutions, chiral centers and synthetic accessibility, it fills the shortage of medium-ring scaffolds. Ideal for HTS, virtual screening and SAR studies, these novel, patent-clear compounds offer a distinctive starting point for drug discovery in CNS disorders, oncology, antivirals and challenging targets such as PPIs.
