摘要:
Linear and cyclic peptides are provided specific to one or melanocortin receptors, and which exhibit agonist, antagonist, or mixed agonist-antagonist activity. In one embodiment, a linear peptide of the following general formula is provided:
摘要:
A cyclic peptide with a C-terminus —OH group. Further provided are compositions and methods for treatment of sexual dysfunction in mammals, including male sexual dysfunction, such as erectile dysfunction, and female sexual dysfunction, by administration of a cyclic peptide including a C-terminus —OH group. Methods of administration include injection, oral, urethral, vaginal, nasal and mucosal administration.
摘要:
Metallopeptide compositions are provided for treatment of sexual dysfunction in mammals, including male sexual dysfunction, such as erectile dysfunction, and female sexual dysfunction. The metallopeptides include at least one, and preferably two, aromatic amino acid side chain moieties, and are further characterized in that the metallopeptides preferably do not bind or significantly bind to a melanocortin receptor.
摘要:
Compositions and methods are described for stabilizing a radio-iodinated monoclonal IgG antibody for up to 17 days against radiolytic decomposition. The stabilized radiolabeled murine antibody binding the CD45 antigen expressed on various forms of lymphomas is useful as a radiotherapeutic and diagnostic agent in the treatment of human malignancies of hematopoietic origin, including lymphomas.
摘要:
A method of making metallopeptide libraries and combinational libraries. The metallopeptide library members name a conformationally constrained global secondary structure obtained upon complexing with a metal ion. The metallopeptides are of the general formula: R1—X—R2 where X is a plurality of amino acids and includes a complexing backbone for complexing metal ions, so that substantially all of the valences of the metal ion are satisfied upon complexation of the metal ion with X, resulting in a specific regional secondary structure forming a part of the global secondary structure; and where R1 and R2 each include from 0 to about 20 amino acids, the amino acids being selected so that upon complexing the metal ion with X at least a portion of either R1 or R2 or both have a structure forming the balance of the conformationally constrained global secondary structure.
摘要:
A thienopyrimidine compound of the formula: wherein R1, R2, R3, and R4 are as defined herein, and methods of use of such compounds for the treatment of melanocortin receptor-associated disorders.
摘要:
Ring-constrained amino acid surrogates of formula I: where R1, R2, R3, R4, R5, R6a, R6b, R7, and y are as defined in the specification, methods for synthesizing ring-constrained amino acid surrogates of formula I, methods of use of ring-constrained amino acid surrogates of formula I, including use in linear or cyclic compounds which include a plurality of amino acid residues and one or more ring-constrained amino acid surrogates of formula I and linear or cyclic compounds which include a plurality of amino acid residues and one or more ring-constrained amino acid surrogates of formula I.
摘要:
Metallopeptides and metallopeptide combinatorial libraries specific for opioids receptors are provided, for use in biological, pharmaceutical and related applications. The metallopeptides and combinatorial libraries are made of peptides, peptidomimetics and peptide-like constructs, in which the peptide, peptidomimetic or construct is conformationally fixed in a biologically active configuration specific for one or more opioid receptors on complexation of a metal ion-binding portion thereof with a metal ion.
摘要:
Cyclic constructs with an N-terminus and a C-terminus which bind to a natriuretic peptide receptor and include a plurality of amino acid residues, at least one amino acid surrogate of formula I: where R, R′, Q, Y, W, Z, J, x and n are as defined in the specification, and optionally at least one prosthetic group, pharmaceutical compositions including such cyclic constructs, and methods of treating congestive heart failure or other conditions, syndromes or diseases for which induction of anti-hypertensive, cardiovascular, renal or endocrine effects are desired.
摘要:
Melanocortin receptor-specific peptide combinatorial libraries for forming metallopeptides and metallopeptide combinatorial libraries are provided for use in biological, pharmaceutical and related applications. The combinatorial libraries are constructed of peptides constructed from naturally occurring amino acids, stereoisomers and modifications of such amino acids, non-protein amino acids, post-translationally modified amino acids, enzymatically modified amino acids, or constructs or structures designed to mimic amino acids, in which the peptides are conformationally fixed on complexation of a metal ion-binding portion thereof with a metal ion.
