Abstract

A pentadecanucleotide was prepared from 1-alpha-arabinofuranosylthymine. This novel oligonucleotide was found to hybridize to oligodeoxyadenylate, although not a s strongly as pentadecathymidylate. It formed duplex hybrids with both DNA and RNA complements, and triplex structures with a duplex containing a (dT)15-(dA)15 tract within a more complex strand. The Tm of the duplex with polyadenylate was almost the same as that of (dT)15 and polyadenylate, while its Tm with (dA)15 was substantially lower than that of the natural counterpart. A selective benzoylation of the 2'-O of a 5'-blocked alpha-ara-thymine was developed to greatly simplify the preparation of suitable blocked material for use in preparation of oligonucleotides on the automated DNA synthesizer.
