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.

原卟啉 IX(P
PIX)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 P
PIX(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 Cu
