The design and synthesis of new molecular hybrids composed of protoporphyrin IX (PPIX) and vitamin B12via copper catalyzed alkyne azide cycloaddition reaction is described. New, clickable aminoazide and aminoalkyne linkers were prepared and subsequently attached to PPIX (via vinyl group) and to vitamin B12giving desired building blocks. Preliminary results showed that respective water soluble hybrids were formed under CuAAC reaction. Gratifyingly, Cu incorporation into the PPIX core was avoided, which was important for further biological studies.
本文介绍了通过铜催化炔吖啶环加成反应设计和合成由原卟啉 IX(PPIX)和维生素 B12 组成的新分子杂化物。研究人员制备了新的、可点击的氨基吖啶和氨基炔连接体,随后将其连接到 PPIX(通过乙烯基)和维生素 B12 上,得到了所需的构建模块。初步结果表明,在 CuAAC 反应中形成了各自的水溶性混合物。令人欣慰的是,Cu 并入 PPIX 核心的情况得以避免,这对进一步的生物研究非常重要。
