    New Nucleoside−Sugar Conjugates:  6-N-Glycosyloxyphosphorylated Adenosine Derivatives as Partial Structures of Agrocin 84
    摘要:
    We report the first successful synthesis of 6-N-[(glucofuranos-1-yloxy)phosphoryl]adenosine as a partial structure of Agrocin 84 via a two-step phosphorylation of 2',3',5'-tri-O-benzoyladenosine with a 2,3,5,6-tetra-O-acetylglucofuranoside 1-O-phosphoramidite derivative that has a 2-(trimethylsilyl)ethyl group as the phosphate protecting group. A similar nucleoside-sugar conjugate, 6-N-[(ribofuranos-1-yloxy)phosphoryl]ade was also synthesized. The stabilities of these 6-N-[(glycos-1-yloxy)phosphoryl] adeno sine derivatives under acidic, basic, and thermal conditions are described. In particular, we found that the P-O bond of these sugar-nucleoside conjugates was selectively cleaved by treatment with 0.1 M NaOH to give 6-N-phosphoryladenosine, while acidic treatment gave directly adenosine with cleavage of the P-N bond.

  • Synthesis and Properties of Aminoacylamido-AMP:  Chemical Optimization for the Construction of an <i>N</i>-Acyl Phosphoramidate Linkage

    This paper describes the design and synthesis of a new type of aminoacyl-adenylate analogue (aa-AMPN) having an N-acyl phosphoramidate linkage where the oxygen atom of the mixed anhydride bond of aminoacyl-adenylate (aa-AMP) is replaced by an amino group. This new type of aa-AMP analogue is expected to be useful as material for studies on the recognition mechanism of the aminoacylation of tRNA and
    本文介绍了具有N-酰基氨基磷酸酯键的新型氨基酰基-腺苷酸类似物(aa-AMPN)的设计和合成,其中氨基酰基-腺苷酸(aa-AMP)的混合酸酐键的氧原子被氨基。这种新型的aa-AMP类似物有望用作研究tRNA氨基酰化和其他生化反应识别机制的材料。羧酰胺的亚磷酰胺衍生物与核苷衍生物的缩合失败,因为活化的亚磷酰胺衍生物不仅与羟基反应,而且与另一种反应性物质反应。通过5'-O-亚磷酰胺基腺苷衍生物与羧酰胺衍生物的反应研究了另一种方法。选择TBTr和TSE基团分别用于保护氨基酸酰胺的氨基和磷酸基。详细研究表明,使用5-(3,5-二硝基苯基)-1H-四唑作为亚磷酰胺的活化催化剂可在10分钟内迅速缩合,从而得到完全保护的aa-AMPN衍生物。没有发生副反应。通过两步程序对这些产物进行脱保护,得到高产率的aa-AMPN衍生物。还证明由此获得的aa-AMPN在酸性和碱性条件下均是稳定的,例如0.1M HCl(pH

    An oligonucleotide protected with N-(trimethylsilyloxycarbonyl) (Teoc) and P-(trimethylsilylethanol) (Tse) groups was synthesized and deprotected by a single ZnBr2 treatment. Finally it was released from the solid support by cleavage of a disulfide linkage with TCEP. The oligonucleotide was obtained without any basic treatment.

The successful synthesis of phosmidosine was achieved by use of a tert-butoxycarbonyl (Boc) group, which was found to be selectively introduced into the 7-NH function of 8-oxoadenosine and to serve as a pseudo-protecting group due to its steric effect in such manner that the unmasked 6-amino group was not phosphitylated. Final coupling reaction of the

The NMR analysis suggests that this cyclouridylic acid derivative has exclusively the C3'-endo conformation that is in favor of duplex formation with RNA. Two oligonucleotides ¿pc3Um(pT)(9) and pc3Um(pU)(9) incorporating this cyclouridylic acid unit at the 5'-terminal site were synthesized by using the fully protected
