We at Enamine are constantly working on synthesizing new molecules and elaborating new synthetic approaches to facilitate access to the most demanded chemistry and intermediates for the Drug Discovery Community. We carefully designed and synthesized a series of E3 binders with attached linkers of different lengths and natures to support Degrader Research and Development. Our primary focus has been the derivatization of Cereblon (CRBN) binders since they are most frequently used in constructing PROTAC molecules.
The Kits represented here include commonly used CRBN ligands functionalized at C4 and C5 positions to avoid interference with binding affinity. The attached ligands are of variable lengths from 2 to up to 18 heavy atoms in the chain or as a part of a more rigid construction.
Apart from the standard PEG and Carba-linkers, we offer intermediates with rigid/cyclic linkers that have been successfully utilized in the design of bifunctional molecules. Linkers terminal functional groups can be easily modified through the most straightforward reactions – amide coupling or click-chemistry.
