摘要:
Novel peptides having potent natriuretic activity are disclosed with the following amino acid sequence: wherein X is L-Ile, D-Ile, D-Ilo-Ile, L-Met or D-Met, Y is Gly, L-Ala or D-Ala, A is H, Ser, Ser-Ser, Arg-Ser-Ser, Arg-Arg-Ser-Ser, Leu-Arg-Arg-Ser-Ser or Ser-Leu-Arg-Arg-Ser-Ser and B is OH, Asn, Asn-Ser, Asn-Ser-Phe, Asn-Ser-Phe-Arg, or Asn-Ser-Phe-Arg-Tyr, and all optically active amino acid residues may be D or L provided at least one amino acid has D-configuration, and the amides, lower alkyl esters and the physiologically acceptable metal salts and acid addition salts thereof.
wherein G is a dipeptide isostere substituted with a polyether, B an amino acid or analog thereof, and J a small terminal group are described. These compounds are useful in the inhibition of DIV protease, the prevention or treatment of infection by HIV and the treatment of AIDS, either as compounds, pharmaceutically acceptable salts, pharmaceutical composition ingredients, whether or not in combination with other antivirals, immunomodulators, antibiotics or vaccines. Methods of treating AIDS and methods of preventing or treating infection by HIV are also described.

Compounds having a quinazolin-2-one nucleus with a substituted alkynyl or substituted alkenyl at the 4-position are described. These compounds are useful in the inhibition of HIV reverse transcriptase (including its resistant varieties), the prevention or treatment of infection by HIV and the treatment of AIDS, either as compounds, pharmaceutically acceptable salts, pharmaceutical composition ingredients, whether or not in combination with other antivirals, immunomodulators, antibiotics or vaccines. Methods of treating AIDS and methods of preventing or treating infection by HIV are also described.

Compounds of the form, A-G-B-B-J wherein A is an amine protecting group or urethane, G a dipeptide isostere substituted with a basic amine nitrogen, B an amino acid or analog thereof, and J a small terminal group are described. These compounds are useful in the inhibition of HIV protease, the prevention or treatment of infection by HIV and the treatment of AIDS, either as compounds, pharmaceutically acceptable salts, pharmaceutical composition ingredients, whether or not in combination with other antivirals, immunomodulators, antibiotics or vaccines. Methods of treating AIDS and methods of preventing or treating infection by HIV are also described.
摘要:
Novel peptides having potent natriuretic activity are disclosed with the following amino acid sequence: wherein X is Ile or Met, A is the N-terminal group of Cys, Ser, Ser-Ser, Arg-Ser-Ser, Arg-Arg-Ser-Ser, Leu-Arg-Arg-Ser-Ser or Ser-Leu-Arg-Arg-Ser-Ser and B is the C-terminal group of Cys, Asn, Asn-Ser, Asn-Ser-Phe, Asn-Ser-Phe-Arg, or Asn-Ser-Phe-Arg-Tyr, provided one optically active amino acid residue is substituted by Ala or Abu (a-amino-butyric acid), or one Gly is substituted by Abu, and the amides, lower alkyl esters and the physiologically acceptable metal salts and acid addition salts thereof. A disulfide bond between the two cysteine residues may be present or absent. When the amino acid in positions 12 or 28 is other than Cys, the peptide is linear rather than cyclic.
wherein A is an amine protecting group or urethane, G a dipeptide isostere and J a small terminal group are described. They are distinguished by tetrahydrofuryl or tetrahydropyranyl substituents, and the like. These compounds are useful in the inhibition of HIV protease, the prevention or treatment of infection by HIV and the treatment of AIDS, either as compounds, pharmaceutically acceptable salts, pharmaceutical composition ingredients, whether or not in combination with other antivirals, immunomodulators, antibiotics or vaccines. Methods of treating AIDS and methods of preventing or treating infection by HIV are also described.
