Coelenterazine analogues possessing the adamantylmethyl group at the C2 or C8 position were prepared to study their effects on chemi- and bioluminescence. Stability of the excited state coelenteramide analogues was significantly affected by the substitutions, resulting in a neutral amide emission of chemiluminescence in diglyme-acetate buffer and in a blue-shifted emission of bioluminescence in Tris-HCI
制备了在C2或C8位具有金刚烷基甲基的腔肠素类似物,以研究其对化学发光和生物发光的影响。取代显着影响激发态腔肠酰胺类似物的稳定性,导致在二甘醇二甲醚乙酸酯缓冲液中化学发光的中性酰胺发射和在Tris-HCl缓冲液中蓝光发射的生物发光。在C8位上的金刚烷基甲基取代导致生物发光强度加倍。8-金刚烷基甲基可以用于将腔肠素骨架定向在活性位点的合适位置,以进行有效的生物发光活性。包含8-金刚烷基甲基类似物的半合成AQ以及包含2-苄基和2-甲基类似物的半合成AQ的结果,
