以1-疊氮基-2-(2-(2-甲氧基乙氧基)乙氧基)乙烷為原料合成3,6,9-三氧雜-1-氨基癸烷的一般步驟如下:參照?qǐng)D1,采用氫化鋁鋰在乙醚(Et2O)中的還原反應(yīng)或鈀催化的氫化反應(yīng)對(duì)疊氮化物(1c)進(jìn)行還原,得到目標(biāo)產(chǎn)物PEG-胺(1)。具體操作如下:將mPEG-疊氮化物(23.1g,132mmol)溶解于無(wú)水乙醚(250mL)中,室溫下緩慢滴加至LiAlH4(2.19當(dāng)量,10.96g,287.2mmol)的無(wú)水乙醚(150mL)懸浮液中。在氮?dú)獗Wo(hù)下攪拌反應(yīng)1小時(shí)后,將反應(yīng)混合物置于冰水浴中冷卻。首先緩慢加入少量甲醇,隨后在氮?dú)獗Wo(hù)下非常緩慢地加入冰水,直至通過(guò)觀(guān)察氫氣釋放結(jié)束來(lái)判斷反應(yīng)完成。過(guò)濾去除無(wú)機(jī)副產(chǎn)物。向水層中加入固體氯化鈉以降低mPEG-胺在水中的溶解度,隨后用二氯甲烷(CH2Cl2)萃取水層。有機(jī)層經(jīng)無(wú)水硫酸鎂(MgSO4)干燥后,真空濃縮得到淺黃色油狀物1。1H NMR(CDCl3, 500MHz)數(shù)據(jù)如下:δ3.70-3.65(m,6H),3.58(t,2H),3.53(t,2H),3.41(s,3H),2.89(t,2H)。

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.
