activity, in vitro translation inhibition, and polypeptide release triggered by the uncaging of NVOC‐puromycin were equivalent to those of the commercial compound. The quantum yield of photolysis was determined to be 1.1±0.2 % and the NVOC‐puromycin was applied to the detection of newly translated proteins with remarkable spatiotemporal resolution by using two‐photon laser excitation, puromycin immunohistochemistry
抑制蛋白质翻译的抗生素嘌呤霉素被用于广泛的生化应用中。介绍了NVOC-嘌呤霉素的合成,表征和生物学应用,NUVOC-嘌呤霉素是一种被紫外线照射激活的光笼衍生物。笼中的化合物对原核或真核翻译或HEK 293细胞的活力均无影响。此外,在体外未检测到核糖体结合的多肽链的显着释放。照射后,NVOC-嘌呤霉素解笼引发的细胞毒性活性,体外翻译抑制作用和多肽释放与市售化合物相同。测得光解的量子产率为1.1±0。
