Uses
A sulfhydryl and amino reactive heterobifunctional protein crosslinking reagent. Spacer Arm: 1.5 Angstroms
reaction suitability
reagent type: cross-linking reagent
Biological Activity
SIA Crosslinker is a non-cleavable ADC linker that can be used to synthesize antibody drug conjugates (ADCs).
Synthesis
6066-82-6
64-69-7
39028-27-8
N-hydroxysuccinimide (12.6 mmol) and dicyclohexylcarbodiimide (20.3 mmol) were dissolved in an appropriate amount of solvent at 0 °C, followed by the addition of iodoacetic acid (6 mmol). The reaction mixture was gradually warmed up to room temperature with continuous stirring for 4 hours. For the synthesis of compound VIa, maleic anhydride (10 mmol) was pre-reacted with β-alanine in N,N-dimethylformamide for 1 hour. After completion of the reaction, the solvent was removed by distillation under reduced pressure and the crude product was dissolved in dichloromethane and washed with water. The organic layer was dried with anhydrous magnesium sulfate, filtered and concentrated to dryness. The residue was purified by recrystallization to afford the target product succinimidyl iodoacetate (VIb) in 30% yield. The structure of the product was confirmed by 1H NMR (CDCl3) and 13C NMR (CDCl3): 1H NMR (CDCl3) δppm: 2.87 (2H, s), 3.96 (1H, s); 13C NMR (CDCl3) δppm: -12.47 (1C, s) 25.85 (2C, s) 164.78 (1C, s) 168.78 (2C, s).
in vitro
ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker.
