摘要:
Biologically active derivatives of norepinephrine are disclosed. Such derivatives are catecholamines wherein isoproterenol is modified by extending the isopropyl functional grouping to an alkyl, aryl, or alkyl-aryl chain of variable length where said chain terminates in a carboxylic acid functional group, or in a substituted amide functional group. Such derivatives are .beta.-adrenergic and a number of such derivatives e.g., 6-(.beta.-3,4-dihydroxyphenyl-.beta.-hydroxy)-ethylamino heptanoic acid p-toluide, 6-(.beta.-3,4-dihydroxyphenyl-.beta.-hydroxy)-ethylamino heptanoic acid para-n-butyl anilide; 6-(.beta.,3,4-dihydroxyphenyl-.beta.-hydroxy)-ethylamino heptanoic acid para-methoxy anilide; 6-(.beta.-3,4-dihydroxyphenyl-.beta.-hydroxy)-ethylamino heptanoic acid paratrifluoromethyl anilide; and 6-(.beta.-3,4-dihydroxyphenyl-.beta.-hydroxy)-ethylamino heptanoic acid N-methyl para-toluide display a .beta.-adrenergic activity at least several orders of magnitude greater than isoproterenol itself. Several methods of producing such active derivatives are also disclosed.

摘要:
Synthetic collagen in triple helical conformation and comprising amino acid chains of repeating trimers of highly populated collagen sequences as well as those sequences wherein the proline or hydroxyproline residue is replaced with a peptoid residue. The invention includes methods of preparing synthetic collagen structures having the triple helix conformation present in collagen from collagen-type polypeptides and poly(peptide-peptoid residue) chains by means of a helix-inducing template.
摘要:
The present invention provides histamine derivatives and methods for using histamine derivatives as immunomodulators and in immunotherapeutics. More specifically the present invention provides methods for inhibiting at least a portion of an an antigen specific antibody response and/or a portion of a T-cell proliferative response by the immune system of a mammal comprising administering to said mammal an effective amount of a composition comprising at least one histamine derivative having binding specificity for at least one histamine receptor.
