Abstract

2D-NOE and 1H NMR chemical shift data obtained for the title oligonucleotides were compared with similar data previously reported [Broido et al. (1985) Eur. J. Biochem. 150, 117-128] for the unmodified "parent" structure, [d(GGAATTCC)]2. The spectroscopically detectable structural perturbations caused by replacement of phosphate oxygen with sulfur were mostly localized within the GsA moiety, and were greater for the Rp configuration wherein sulfur is oriented into the major groove of the B-helix. UV-derived Tm measurements gave the following order of stability for the duplexes in 0.4 M NaCl: unmodified (33.9 +/- 0.1 degrees C) approximately Sp-Sp (34.1 degrees C) greater than Rp-Rp (31.7 degrees C). The title compounds were prepared by a new and convenient synthetic route which utilized HPLC to separate the diastereomeric O-ethyl phosphorothioate precursors, (Rp)- and (Sp)-d[GG(S,Et)AATTCC], for subsequent de-ethylation by ammonia in water.
