6-diaminogalactose scaffold was developed for combinatorial syntheses of potential RNA ligands in the solid phase. A set of selectively removable, orthogonally stable protecting groups in combination with a linker stable throughout the synthesis, but selectively cleavable in the detachment process, allows for selective deprotection and introduction of a side chain in each position of this scaffold. A few of
在氨基糖苷类作为 RNA 的有效结合剂的背景下,开发了一种 2,6-二氨基半乳糖支架,用于在固相中组合合成潜在的 RNA 配体。一组选择性可去除、正交稳定的保护基团与在整个合成过程中稳定但在分离过程中可选择性切割的接头组合,允许在该支架的每个位置选择性脱保护和引入侧链。一些合成的化合物在含有 TAR 控制的报告基因的 HeLa 细胞中表现出对 HIV-1 感染的抑制作用。
