从传统中药到现代抗生素的发现,天然产物在药物开发进程中发挥了重要作用。对所有 FDA 批准的药物评估显示,天然产品及其类似物占所有已批准药物的三分之一以上。其中近一半来自哺乳动物,四分之一来自微生物,四分之一来自植物。随着时间的推移,已上市药物中微生物天然产物和天然产物类似物的占比增加了。天然产物在药物开发中具有天然的优势,可以作为药物发现的先导化合物,用于药物鉴定和机制研究。
Natural products are small molecules produced naturally by any organism including primary and secondary metabolites. Nowadays, new drugs based on Natural products are successfully applied to treat tumors, viral and bacterial diseases, and nervous disorders.
In response to the current drug discovery demand, we created this natural product-like compound library with 13,236 in-stock synthetic compounds similar to natural ones. The library was designed by 2D fingerprint similarity filtering, chemical descriptor-based and natural-likeness scoring selection. These compounds are useful tools for high throughput screening (HTS) and high content screening (HCS) programs.
Natural products are an attractive source with varied structures that exhibit potent biological activities, and desirable pharmacological profiles. The core scaffold of a natural product can also provide a biologically validated framework upon which to display diverse functional groups. Inspired by bioactive natural products, natural product-like compounds, occupying the same chemical space, are ideally suited to explore and to facilitate understanding of biological pathways.
MCE 10K Natural Product-like Compound Library consists of 10,000 natural product-like compounds. Each compound has scaffold of natural products or Tanimoto coefficient >0.6 with natural products. The natural-likeness scoring of these compounds is >-2. What’s more, compounds in the library are drug-like and readily available for re-supply, making it a powerful tool for new drug research and development. It can be widely applied in high-throughput screening (HTS) and high-content screening (HCS).
天然产物是自然界中产生的,来自于任何生物体的小分子化合物,其中包括初级代谢物及次级代谢物。天然产物具有潜在的生物活性,可以作为药物发现的先导化合物。数千年来,大自然一直是药物的来源,大量现代药物从自然界中分离得到,许多是基于它们在传统医学中的用途。随着化合物靶点的开发,对筛选化合物多样性的需求越来越大。通过对自然界生物多样性的持续研究,其中许多生物多样性仍有待开发,天然产物将在满足这一需求方面发挥关键作用。类药五原则(Lipinski rule of 5)是用来描述一个分子类似药物的性质,遵守5法则的分子具有更高的药物潜力。MCE 在已有天然产物库的基础之上,筛选出了符合类药五原则的分子,使得药物筛选的效率更高。
A sub-library of GPCR Library designed for the discovery of novel allosteric ligands. Allosteric GPCRs Library is a utile starting point for the drug discovery in the field of allosteric GPCR modulators.
“BioDesign” approach incorporates key structural features of known pharmacologically relevant natural products (e.g. alkaloids and other secondary metabolites) into synthetically feasible medicinal chemistry scaffolds. In order to identify the privileged pharmacophores, ring systems and linkers, we have carried out statistical analysis of structural features of natural products, marketed drugs, and drug candidates.
Saturated, fused ring, spiro, and bridged systems with a tendency towards multiple chiral centers are highly privileged among natural products and marketed drugs yet these structures are very poorly represented in commercial libraries. This library addressed this market need by incorporating these privileged elements into the design of novel synthetic molecules with high molecular framework diversity, multiple stereogenic centers (≥2), and degree of saturation (Fsp3 > 0.5).
This library contains about 439,804 natural and synthetic screening compounds. The information in the database includes logP, H-bond donors, H-bond acceptors, rotable bonds.
A unique collection of 25,361 bioactive compounds including natural products, enzyme inhibitors, receptor ligands, and drugs for high throughput screening (HTS) and high content screening (HCS).
Glycomimetics are designed to mimic the structure of natural carbohydrates and modulate their disease-related functions. Macrocyclic glycomimetics are an extremely interesting class of glycomimetics as they occupy space between small and macro molecules. Macrocyclic glycomimetics are mostly represented by naturally occurring molecules derived from marine microorganisms and bacterial or fungal metabolites.
Antibacterial Library contains about 32,000 compounds, and is designed for discovery of novel antibacterials. The new antibacterial library uses substructure and shape-based searches to select molecules with privileged cores, motifs, and natural product-like scaffolds that are known to be critical for antibacterial activity.
A unique set of molecules containing mild electrophilic moieties that covalently interact with amino acid residues in the target protein. The diversity of our compounds for covalent drug discovery ranges from natural product-like scaffolds to macrocycles, creating multiple opportunities in hit generation for a selected target.
The Chinese National Compound Library (CNCL) composes 1.4 million compounds possessing diversified structures. Coupled with this library will be advanced sample handling, information management and quality control systems. Most compounds in the library are drug-like, conforming to “Lipinski’s Rule of Five”, such as MW < 500, logP < 5, Hydrogen Bond Donors < 5.
2024年5月,Nature杂志在线发表了题为“Dimerization and antidepressant recognition at noradrenaline transporter”的研究论文,该研究成果由中国科学院上海药物研究所完成。该研究破解了重要神经系统疾病靶标——去甲肾上腺素转运体(NET),获得了人源NET同源二聚体分别与转运天然底物去甲肾上腺素NE,以及六种选择性抗抑郁药物的结合模式,为理解NET等单胺类转运体的生理调控机制奠定了重要的理论基础。
