摘要:
Fusion of the viral envelope, or infected cell membranes with uninfected cell membranes, is an essential step in the viral life cycle. Recent studies involving the human immunodeficiency virus type 1 (HIV-1) demonstrated that synthetic peptides (designated DP-107 and DP-178) derived from potential helical regions of the transmembrane (TM) protein, gp41, were potent inhibitors of viral fusion and infection. A computerized antiviral searching technology (C.A.S.T.) that detects related structural motifs (e.g., ALLMOTI5, 107×178×4, and PLZIP) in other viral proteins was employed to identify similar regions in the respiratory syncytial virus (RSV). Several conserved heptad repeat domains that are predicted to form coiled-coil structures with antiviral activity were identified in the RSV genome. Synthetic peptides of 16 to 39 amino acids derived from these regions were prepared and their antiviral activities assessed in a suitable in vitro screening assay. These peptides proved to be potent inhibitors of RSV fusion. Based upon their structural and functional equivalence to the known HIV-1 inhibitors DP-107 and DP-178, these peptides should provide a novel approach to the development of targeted therapies for the treatment of RSV infections.

摘要:
The invention relates to medicine, specifically, to methods of obtaining biologically active substances with immuno-regulating properties, and can be used in medicine and veterinary science and in experimental biochemistry. The fundamental problem addressed by the invention is that of producing a noval synthetic biologically active peptide with immuno-regulating properties and of the formula: X-Glu-Trp-Y, in which X is H or Gly, Ala, Leu, Ile, Val, NVal, Pro, Tyr, Phe, Trp, D-Ala, D-Leu, D-Ile, D-Val, D-NVal, D-Pro, D-Tyr, D-Phe, D-Trp, .gamma.-aminobutyric acid, .zeta.-aminocapronic acid; Y is Gla, Ala, Leu, Ile, Val, NVal, Pro, Tyr, Phe, Trp, D-Ala, D-Leu, D-Ile, D-Val, D-NVal, D-Pro, D-Tyr, D-Phe, D-Trp, .gamma.-aminobutyric acid .zeta.-aminocapronic acid, --OH, NH.sub.2,N.sub.2 H.sub.3, mono- or di-substituted amide (C.sub.1 -C.sub.3). Peptide synthesis takes place in a solution by successive growth of a chain from the C termination of the molecules, using a strategy of maximum blocking of functional groups, starting from amino acid alkyl ether, using the method of activating the ethers and the method of mixed anhydrides using tributyloxicarbonyl amino acid, with the proviso when X is H, Y is not OH.
