點(diǎn)擊反應(yīng)是一類具有定量、快速、高效、立體選擇性、很少甚至沒有副產(chǎn)物生成、反應(yīng)條件溫和等特點(diǎn)的化學(xué)反應(yīng)。傳統(tǒng)的點(diǎn)擊反應(yīng)是指銅(I)催化的疊氮化物和端炔的1,3-偶極環(huán)加成反應(yīng))。 眾所周知,銅(I)具有細(xì)胞毒性,可損傷紅細(xì)胞,使傳統(tǒng)的點(diǎn)擊反應(yīng)在生物醫(yī)學(xué)應(yīng)用中受到限制。
早在1961年,Witting在“ZurExistenz NiedergliedrigerCycloalkine,I和II”中就提到苯基疊氮與環(huán)辛炔能夠發(fā)生無銅催化的點(diǎn)擊反應(yīng)。然而,大多數(shù)環(huán)辛炔試劑又不具有良好的水溶性,限制了它們在生物醫(yī)藥中的應(yīng)用。
鍵凱科技擁有一系列聚乙二醇-環(huán)辛炔衍生物的專利(發(fā)明專利,專利號:ZL201310300951.6),這些環(huán)辛炔衍生物可以在無銅的條件下與疊氮化物反應(yīng),從而使后處理非常簡單,消除了傳統(tǒng)點(diǎn)擊化學(xué)的細(xì)胞毒性問題。鍵凱科技PEG-環(huán)辛炔衍生物具有良好的水溶性和生物相容性。聚乙二醇衍生物廣泛應(yīng)用于多肽、蛋白質(zhì)和藥物傳遞中,以延長半衰期,降低免疫原性和毒性,也可與藥物分子通過PEG化結(jié)合,作為水凝膠的一部分。
新型PEG環(huán)新炔衍生物的優(yōu)點(diǎn):
無銅條件下與疊氮化物進(jìn)行點(diǎn)擊反應(yīng)
與傳統(tǒng)的點(diǎn)擊化學(xué)相比,沒有細(xì)胞毒性問題,
良好的水溶性和生物相容性
在藥物輸送中的應(yīng)用,可以延長半衰期,降低藥物免疫原性和毒性
多臂PEG環(huán)辛炔衍生物可用于形成水凝膠
