In this work, we report the synthesis of an alternate nucleo-alpha,epsilon-peptide based on L: -lysine moieties, an in vitro study of its biological activity, and spectroscopical binding studies between the novel nucleopeptide and Moloney murine leukemia virus reverse transcriptase as well as RNA. An alternate homothymine hexamer was synthesized by a straightforward solid phase route starting from commercial materials, purified by RP-HPLC and characterized by ESI-MS. The efficiency of the novel nucleo-alpha,epsilon-peptide in interfering with the reverse transcription of eukaryotic mRNA and the noteworthy enzymatic resistance demonstrated by specific assays are in favor of the employment of this nucleopeptide in novel biomedical strategies.

UI MeSH Term Description Entries
D008979 Moloney murine leukemia virus A strain of Murine leukemia virus (LEUKEMIA VIRUS, MURINE) arising during the propagation of S37 mouse sarcoma, and causing lymphoid leukemia in mice. It also infects rats and newborn hamsters. It is apparently transmitted to embryos in utero and to newborns through mother's milk. Moloney Leukemia Virus,Leukemia Virus, Moloney,Virus, Moloney Leukemia
D010455 Peptides Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS. Peptide,Polypeptide,Polypeptides
