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.
ASINEX has elaborated a library of diverse macrocycles using an effective tool box of synthetic methods. The resulting scaffolds are novel, tremendously diverse, medchem-relevant, macrocyclic frameworks.
Macrocyles tend to be larger than traditional screening molecules which make them perfect discovery tools for targets with shallow or extended binding sites. At the same time, their unique character based on restricted flexibility and ability to form intra-molecular hydrogen bonds allows for design approaches effectively optimizing properties such asaqueous solubility and membrane permeability. Many of these macrocycles have been tested for aqueous and DMSO solubility with cut-offs applied at 10 mM in DMSO and 50 µM in PBS (pH 7.4) followed by PAMPA permeability assay.
OTAVAchemicals Screening Collection contains about 270,000 re-supply compounds for prompt delivery. All compounds have undergone quality control to confirm their chemical structures.
Vitas-M Screening Compounds Library (stock) contains about 1,400,000 chemical substances. They are synthetic small molecule organic compounds for biological screening and lead optimization. Select any number of items as a "cherry pick".
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.
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。
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).
