UORSY Screening Compounds Library contains about 680,000 compounds. The library has extensively developed a polymerization synthesis method that provides a highly diverse chemical structure. More than 85% of the compounds in the library have drug-like physicochemical properties, and more than 35% of the compounds have lead-like properties.
Diversity-based screening continues to be a vital tool for drug discovery. Efficiency and productivity can be improved by using screening libraries that offer maximum diversity whilst retaining drug-like properties. Chemspace Scaffold derived set composes 10,119 compounds, which including 3,373 scaffolds, 3 compounds per each. This library has exceptional coverage of drug-like chemical space.
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。
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.
The incidence and significance of central nervous system diseases are increasing at an alarming rate all over the world. Although substantial research efforts have been applied to develop new CNS-active drugs, only a few CNS disorders are addressed satisfactorily, while the remaining ones pose significant clinical challenges. Blood-brain barrier (BBB) permeability is one of the most important limiting factors in the design and development of novel CNS-targeted pharmaceuticals for the treatment of neurological disorders.
Carefully selected from the HTS Compound Collection to meet the parameters optimized for high BBB-permeability, our CNS Focused Screening Library comprising over 30,300 structurally-diverse and potentially CNS-active screening compounds. This original Screening Compound Library is aimed at supporting CNS drug design projects and HTS efforts in search for novel neurotherapeutics.
A specially synthesized set of 2 compounds able to mimic glycosides and their interaction with proteins. The main emphasis of library design was made on drug-like compounds enriched with H-bond donors (possess at least two H-bond donors) and bearing nature-like Fsp3–rich scaffolds with diverse spatial orientation of H-bond donors and different 3D-shapes.
Life Chemicals Collection of small organic molecules for high-throughput screening currently contains 503,810 off-the-shelf products. The Collection is being permanently replenished with de novo designed products having optimal physicochemical parameters for drug discovery.
Macrocycles are promising scaffolds for the design of novel RNA targeting molecules. This collection of macrocycles for RNA consists of very diverse, drug-like molecules which incorporate certain known RNA-recognition elements (e.g. nucleobase ring systems and analogs) distributed within macrocyclic rings or peripheral fragments. As macrocyclic molecules tend to be larger than traditional screening molecules, it is vital to carefully assess and control their physicochemical properties. All macrocycles have been tested for aqueous and DMSO solubility with cutoffs applied at 10 mM in DMSO and 50 µM in PBS (pH 7.4); PAMPA permeability has also been tested for representative set of macrocycles.
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).
InterBioScreen Synthetic Compounds Library contains about 485,000 immediately available compounds. The library is generated by very rigorously selecting the most interesting classes of compounds that are most likely to become new drugs or plant protection agents or veterinary preparations.
Maybridge Screening Collection is a highly diverse set of over 53 hit-like and lead-like molecules widely acknowledged as a critical tool in screening campaigns.
