It is an object of the present invention to provide a method for highly selectively releasing a molecule of interest such as an agent at a desired site while suppressing the influence of catabolic enzymes existing in vivo. The present invention provides a method for releasing a molecule of interest, which comprises steps of: hybridizing each of an "electron donor-first nucleic acid probe" molecule formed by binding an electron donor structure to a first nucleic acid probe having a nucleotide sequence complementary to a portion of a target nucleic acid sequence and a "molecule of interest-electron acceptor-second nucleic acid probe" molecule formed by binding an electron acceptor structure having a molecule of interest and an azide group to a second nucleic acid probe that has a nucleotide sequence complementary to said target nucleic acid sequence and differing from that of said first nucleic acid probe, to said target nucleic acid sequence; and allowing said "electron donor-first nucleic acid probe" molecule to act on said "molecule of interest-electron acceptor-second nucleic acid probe" molecule, so as to release said molecule of interest.
本发明的目的是提供一种高度选择性地在所需位置释放感兴趣的分子(如药物),同时抑制体内存在的分解酶的影响的方法。本发明提供了一种释放感兴趣分子的方法,包括以下步骤:将电子给体结构与具有与目标核酸序列部分互补的第一核酸探针结合形成的“电子给体-第一核酸探针”分子和将具有感兴趣分子和
叠氮基团的电子受体结构与具有与目标核酸序列互补且与第一核酸探针不同的第二核酸探针结合形成的“感兴趣分子-电子受体-第二核酸探针”分子与目标核酸序列杂交;并使“电子给体-第一核酸探针”分子作用于“感兴趣分子-电子受体-第二核酸探针”分子,以释放所述感兴趣分子。
