PROTAC Linkers

Research Areas:  

Cancer

Boc-7-Aminoheptanoic acid can be used as a PROTAC linker in the synthesis of PROTACs and other conjugation applications. Boc-7-Aminoheptanoic acid is an alkane chain with terminal carboxlic acid and Boc-protected amino groups. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. The Boc group can be deprotected under mild acidic conditions to form the free amine.

Cat. No.: HY-Y1091
CAS No.: 923-27-3
D-Lysine is the D-enantiomer of L-Lysine (HY-N0469). D-Lysine is metabolically inert and not utilized for protein synthesis by mammalian ribosomes. D-Lysine blocks renal uptake of 111In/ 90Y-Octreotide (HY-P0036)-based probes without inhibiting uptake by tumor/receptor tissues, and thus acts as a renoprotective agent in diagnostic imaging and peptide receptor radionuclide therapy (PRRT). D-Lysine specifically inhibits the early steps of non-enzymatic glycation by competing with glucose via its free amino group, theoretically, it can serve as a glycation competitor that "does not interfere with protein synthesis" under chronic hyperglycemia in diabetes. D-Lysine can be used in research related to cancer and diabetes .

CAS No.: 616-02-4
Synonyms: Methylmaleic anhydride
Citraconic anhydride (Methylmaleic anhydride) is a derivative of maleic anhydride (HY-Z0060) and novel antigen retrieval solution. Citraconic anhydride reversibly blocks protein amino groups, stabilizing specific enzymes and improving their catalytic performance. Citraconic anhydride reacts with free amino groups on proteins (especially lysine residues), converting positively charged NH3 + into carboxyl groups, thereby disrupting methylene bridge crosslinks caused by Formaldehyde during antigen retrieval. Citraconic anhydride functionalizes Isotactic polypropylene. Citraconic anhydride precisely responds to pH changes to achieve reversible modification. Citraconic anhydride is irritating to skin and eyes .

2,5-Dioxopyrrolidin-1-yl acrylate (N-Succinimidyl acrylate) is a lysine residue modifier and coupling monomer. 2,5-Dioxopyrrolidin-1-yl acrylate covalently modifies the primary amines of lysine residues on monoclonal anti-horseradish peroxidase IgG antibodies, neutralizes positive charges and replaces them with low-affinity acrylate groups. 2,5-Dioxopyrrolidin-1-yl acrylate inhibits the formation of rapid hard coronas on citrate-coated gold nanoparticles, induces antibody unfolding and loss of antigen-binding function, but does not affect the antigen-binding function of antibodies in free solution. 2,5-Dioxopyrrolidin-1-yl acrylate reacts with the ε-amino groups on lysine residues of L-asparaginase, introduces vinyl groups and generates N-hydroxysuccinimide. 2,5-Dioxopyrrolidin-1-yl acrylate regulates the activity of L-asparaginase .
