The present invention provides gapped oligomeric compounds comprising from 1 to about 3 internucleoside linkages having one of formulas I to XVI. In certain embodiments, inclusion of from 1 to about 3 internucleoside linkages of one of formulas I to XVI, improves selectivity for a target RNA relative to an off target RNA. In certain embodiments, the improved selectivity also provides an improved toxicity profile. Certain such oligomeric compounds are useful for hybridizing to a complementary nucleic acid, including but not limited, to nucleic acids in a cell. In certain embodiments, hybridization results in modulation of the amount of activity or expression of the target nucleic acid in a cell.
本发明提供了包含从1到大约3个核苷酸间连接的间隙寡聚合物化合物,其中所述核苷酸间连接具有I至XVI式中的一种。在某些实施例中,包含I至XVI式中的一种核苷酸间连接,可以提高与目标RNA相对于非靶RNA的选择性。在某些实施例中,提高的选择性还提供了改进的毒性概况。某些这样的寡聚合物化合物适用于与互补核酸杂交,包括但不限于细胞中的核酸。在某些实施例中,杂交导致细胞中目标核酸的活性或表达量的调节。
