443 compounds
In modern medicinal chemistry and chemical biology research, alkyne (-C≡C-) structures play an important role in click chemistry, bioorthogonal labeling, and the construction of functional molecules due to their unique linear geometry and high reactivity. In particular, driven by the development of copper-catalyzed azide-alkyne cycloaddition (CuAAC) and copper-free click reactions (SPAAC), terminal alkyne groups have become important “chemical handles” for building complex biomolecular systems.
The MCE Alkyne Compound Library contains 443 compounds designed for the construction of click chemistry reaction systems and the development of diverse functional molecules. In drug discovery, these structures serve as key reactive sites that can efficiently undergo click reactions with azide groups, enabling modular assembly of PROTAC molecules, construction of ADC linkers, and rapid synthesis of bioorthogonal labeling probes. In addition, alkyne groups exhibit high stability, mild reaction conditions, and excellent biocompatibility, allowing them to maintain reactivity in complex biological environments. This contributes to improved efficiency and controllability in drug development, making them indispensable chemical building blocks in modern drug design and functional molecular engineering.
Cat. No.: HY-L259
231 compounds
In PROTAC drug development, linkers are often one of the key variables determining drug-likeness and degradation efficiency. Since PROTAC systems must simultaneously satisfy target protein binding, E3 ligase recruitment, and intracellular spatial conformational matching, their structural design is essentially a multi-parameter optimization problem. Differences in linker rigidity, flexibility, and spatial extension can significantly influence the formation pathway and stability of the ternary complex, leading to substantial variations in degradation activity. Therefore, the development of linker systems with modular tunability and high structural expandability has become an important direction in PROTAC optimization.
The MCE Alkyne PROTAC Linker Library contains 231 linkers based on terminal and internal alkyne scaffolds, forming a highly derivatizable linker module system. These linkers serve as standardized building blocks for rapid assembly and iterative optimization of PROTAC molecules, and support efficient conjugation with azide-containing functional groups via click chemistry. In practical drug development, this type of structure not only facilitates the construction of diverse linker space libraries, accelerating lead compound screening, but also enables systematic tuning of molecular geometry and physicochemical properties, thereby improving ternary complex stability and targeted protein degradation efficiency.
