●外观以及性质:
IR-808 alkyne含有IR和炔烃基团,近红外区域吲哚花菁素IR可连接修饰alkyne基团,炔烃(alkyne)是常用生物标记基团。通过铜催化点击化学反应(Copper-catalyzed azide–alkyne cycloaddition,CuAAC),炔烃可以和叠氮(azide)生成稳定的生物链接(bioconjugate)。
近红外吲哚类花菁染料IR-808可被tumour细胞高选择性摄取,并在近红外光射下,展现出对tumour细胞的显著光敏毒性,与传统的光敏剂相比,该光敏剂只需些近红外光照射,不但可大大降低组织对光的吸牧,增强其光敏作用。
IR-808 alkyne contains IR and alkyne groups. Indocyanine IR in the near-infrared region can connect and modify alkyne groups. Alkyne is a common biomarker group. Through copper-catalyzed azide – alkyne cycloaddition (CuAAC), alkynes can form stable biological links with azide.
The near-infrared indole cyanine dye IR-808 can be highly selectively absorbed by tumour cells, and under near-infrared light, it shows significant photosensitivity toxicity to tumour cells. Compared with traditional photosensitizers, this photosensitizer only needs some near-infrared light irradiation, which can not only greatly reduce the light absorption of tissues, but also enhance its photosensitivity.
