Abstract:
Two conjugates of an anti-HIV oligonucleotide (ODN) with different high molecular weight monomethoxy polyethylene glycols (MPEGs) have been tested for their activity as substrate towards RNase H. The MPEG does not impede the formation of the regular hybrid duplex with the target RNA sequence as pointed out by the persistence of the RNase H activity; thus, these derivatives stimulate the hydrolysis of RNA by the enzyme at the same site and with the same extent of cleavage as the native sequence.
