Belyntic's Peptide Easy Clean (PEC) technology breaks barriers in peptide manufacturing. We designed a catch-and-release methodology based on novel traceless cleavable linker molecules (PEC-Linkers) and activated filter materials for the purification and modification of chemically synthesized peptides.

The most popular linker is the protease cleavable linker that contains a valine-citrulline-para-aminobenzyl-carbamate moiety (vc-PABC). 10 This is a traceless linker that allows the release of amine containing cytotoxins. Oct 14, 2016 · Cleavable linkers. A major class of ADC linkers is the cleavable linker (Fig. 7). Cleavable linkers are designed to be cleaved by responding to an environmental difference between the extracellular and intracellular environments (pH, redox potential, etc.) or by specific lysosomal enzymes. So, ADCs with noncleavable linkers are more dependent on the biology of the target cell compared to cleavable linkers. Moreover, these ADCs have improved therapeutic index due to their greater stability. The most advantage of using non-cleavable linkers is their increased plasma stability when compared to many cleavable linkers. Owing to its slow and variable release, an alternative is urgently required to improve effectiveness. Herein we describe a PEGylated colistin prodrug whereby the PEG is attached via a cleavable linker (col-aaPEG) introducing an acetic acid terminated poly (ethylene glycol) methyl ether (aaPEG) onto the Thr residue of colistin. Relatively few cleavable linkers are available for DNA-directed synthesis and most often they leave an amino group at the organic molecule. Here we have extended the application of aryltriazenes as traceless linkers for DNA-directed synthesis. For example, in a systematic study aimed at identifying the optimal targets and linker–drug combinations for the treatment of non-Hodgkin lymphoma, it was found that ADCs with cleavable or hydrolysable linkers (e.g., disulfides, hydrazones) were efficacious even with antibodies specific to targets that were poorly internalized (e.g., CD20

Cleavable linkers are generally preferred to non-cleavable linkers in ADC research for a number of reasons. 5 First, traceless drug release allows the unmodified payload to perform its intracellular function without an unwanted linker appendage, thereby maximising cytotoxicity.

The hydrazide group is an oxidatively cleavable traceless linker for solid-phase chemistry. This linker technology was used to develop a multistep solid-phase synthesis of an antibiotic that is Releasable conjugation of polymers to proteins 1 Releasable conjugation of polymers to proteins Yuhui Gong1, Jean-Christophe Leroux1, and Marc A.
