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.
Protein protein interactions (PPI) have pivotal roles in life processes. The studies showed that aberrant PPI are associated with various diseases. However, the design of modulators targeting PPI still faces tremendous challenges, such the difficult PPI interfaces for the drug design, lack of ligands reference, lack of guidance rules for the PPI modulators development and high-resolution PPI proteins structures.
The PPI Library comprises molecules of various sizes, frameworks, and shapes ranging from fragment-like entities to macrocyclic derivatives designed as secondary structure mimetics or as epitope mimetics. The designs cover β-turn / loop mimetics and α-helix mimetics. Since helices present at the interface in 62% of all protein-protein interactions. This library focused on designs including mimics with the substitution geometry of an a-helices, as well as designs that mimic the location of “hot-spot” side chains in helix-mediated PPIs.
Sodium Ion Channel Library contains about 5,440 compounds, and designed for discovery of new Nav1.7 channel blockers. Sodium voltage-gated ion channel is considered to be an important component in nociception. Therefore, selective Nav1.7 channel blockers are considered as important novel analgesics. The Sodium Ion Channel Library is rich in compounds bearing saturated backbones that can be often seen in structures of other ion-channel blockers.
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).
MCE 3D 多样片段库由 5,400 个非平面片段分子组成（平均 Fsp3 值为 0.58），超过4,700个片段至少包含一个手性中心。本库设计的关键元素是 3D 结构、多样性、生物反应性等。另，库中化合物在保证高sp3中心和 3D 结构优势的同时，还有效提高了片段潜在生物活性，为基于片段的药物发现提供了更高的片段命中优化概率，增加了找到创新命中的可能性。
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.
