In 2018,Rubner, Stefan; Scharow, Andrej; Schubert, Sabine; Berg, Thorsten published 《Selective Degradation of Polo-like Kinase 1 by a Hydrophobically Tagged Inhibitor of the Polo-Box Domain》.Angewandte Chemie, International Edition published the findings.Product Details of 139115-91-6 The information in the text is summarized as follows:
Hydrophobic tagging (HT) of bioactive compounds can induce target degradation via the proteasomal pathway. The first application of hydrophobic tagging to an existing inhibitor of protein-protein interactions is now presented. We developed Poloxin-2HT by fusing an adamantyl tag to Poloxin-2, an inhibitor of the polo-box domain (PBD) of the protein kinase Plk1, which is a target for tumor therapy. Poloxin-2HT selectively reduced the protein levels of Plk1 in HeLa cells and had a significantly stronger effect on cell viability and the induction of apoptosis than the untagged PBD inhibitor Poloxin-2. The change in cellular phenotype associated with the addition of the hydrophobic tag to Poloxin-2 demonstrated that Poloxin-2HT targets Plk1 in living cells. Our data validate hydrophobic tagging of selective inhibitors of protein-protein interactions as a novel strategy to target and destroy disease-relevant proteins.tert-Butyl (2-(2-hydroxyethoxy)ethyl)carbamate(cas: 139115-91-6Product Details of 139115-91-6) was used in this study.
tert-Butyl (2-(2-hydroxyethoxy)ethyl)carbamate(cas: 139115-91-6) belongs to ethers.Ethers do have nonbonding electron pairs on their oxygen atoms, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. Product Details of 139115-91-6 The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.
