The synthesis of novel functionalized fullerene derivatives is
reported: a DNA minor groove binder such as trimethoxy-
indole-2-carboxylate (TMI) and an oligonucleotide chain have been
covalently linked to C60 with the aim of duplicating DNA
interactions for increasing sequence selectivity.

The synthesis of novel functionalized fullerene derivatives containing DNA minor groove binders is reported. In order to construct sequence-specific probes for DNA photomodification, the compounds were attached to a triplehelixformingoligonucleotide, and the formation of triplexes was monitored. The triplex formation was demonstrated, but the presence of fullerene moieties gives rise to a high degree
报道了含有 DNA 小沟结合剂的新型功能化富勒烯衍生物的合成。为了构建用于 DNA 光修饰的序列特异性探针,将化合物连接到形成三螺旋的寡核苷酸上,并监测三链的形成。证明了三链体的形成,但富勒烯部分的存在导致高度的不稳定性。对这些超分子结构的分子建模研究为当前的研究和未来的发展提供了有用的信息。
