Disclosed are thyclotides, which are oligomers, each comprising (a) from about 8 to about 25 monomer units of formula (I) and (b) from 0 to about 24 monomer units of formula (II): wherein B is a nucleobase, which can be the same or different at each occurrence, or a pharmaceutically acceptable salt thereof. The thyclotides are soluble in water, bind strongly to complementary DNA and RNA, and are cell permeable. The thyclotides are useful as reagents for antisense and antigene applications, and as probes in molecular diagnostics and microarrays.
本发明涉及一种称为thyclotides的寡聚体,每个寡聚体包括(a)约8到约25个式(I)的单体单位和(b)约0到约24个式(II)的单体单位:其中B是核碱基,可以在每次出现时相同或不同,或其药学上可接受的盐。这些thyclotides在
水中溶解,能够强烈结合互补的DNA和RNA,并且具有细胞穿透性。这些thyclotides可用作反义和抗
基因应用的试剂,以及分子诊断和微阵列中的探针。
