以2-(2-BOC-氨基乙氧基)乙醇為原料合成(2-(2-溴乙氧基)乙基)氨基甲酸叔丁酯的一般步驟:將2-(2-BOC-氨基乙氧基)乙醇(1.25 g,6.09 mmol)溶解于二氯甲烷(34 mL)中。將溶液冷卻至0℃,隨后向溶液中依次加入甲磺酰氯(MsCl,0.80 mL,10.3 mmol,1.7當量)和三乙胺(Et3N,1.9 mL,13.4 mmol,2.2當量)。反應混合物在室溫下攪拌3小時后,用丙酮(33 mL)稀釋,并加入溴化鋰(LiBr,8.9 g,103 mmol,17當量)。將反應混合物在室溫下攪拌過夜。反應完成后,減壓蒸發(fā)溶劑。粗產物用乙酸乙酯(EtOAc)稀釋,依次用水和鹽水洗滌。有機相用無水硫酸鈉(Na2SO4)干燥。將懸浮液通過棉花過濾,濾液真空濃縮。通過快速柱色譜法純化,使用石油醚/丙酮(85:15→8:2)作為洗脫劑,得到目標產物(2-(2-溴乙氧基)乙基)氨基甲酸叔丁酯(1.60 g,5.95 mmol,產率98%),為無色油狀物。1H-NMR(500 MHz,CDCl3):δ 4.91(s,1H),3.78(t,2H),3.56(t,2H),3.47(t,2H),3.33(d,2H),1.55(s,9H)。

PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker.
