摘要:
Novel cyclic CRF agonist peptides have the amino acid sequence: (cyclo 30-33)Ac-Pro-Pro-Ile-Ser-Leu-Asp-Leu-Thr-D-Phe-His-Leu-Leu-Arg-Glu-Val-Leu-Glu-Nle-Ala-Arg-Ala-Glu-Gln-Leu-Ala-Gln-R30-Ala-R32-R33-Asn-Arg-Lys-Leu-Nle-Glu-Ile-Ile-NH2 wherein R30 is Glu or Cys; R32 is His or a D-amino acid such as D-His, D-Arg or similar; R33 is Lys, Orn or Cys. The N-terminus may be extended by Ser-Glu-Glu. Lys may be substituted for Arg23, and its side chain connected by a lactam bridge to Glu20 to form a bicyclic peptide. Certain disclosed CRF agonists include: (cyclo 30-33)[Ac-Pro?4, D-Phe12, Nle21,38, D-His32, Glu30, Lys33¿]r/hCRF(4-41), (cyclo 30-33)[Ac-Pro?4, D-Phe12, Nle21,38, D-His32, Glu30, Orn33¿]r/hCRF(4-41), (cyclo 30-33)[Ac-Pro?4, D-Phe12, Nle21,38, Cys30,33, D-His32¿]r/hCRF(4-41), (bicyclo 20-23, 30-33)[Ac-Pro¿4?, D-Phe?12, Nle21,38, Lys23,33, Glu30, D-His32¿]-r/hCRF(4-41), (cyclo 30-33)[Ac-Pro¿4?, D-Phe?12, Nle21,38, CML27, Glu30¿, imBzlD-His?32, Lys33¿]r/hCRF(4-41) and (cyclo 30-33)[Ac-Pro?4, D-Phe12, Nle21,38, Glu30, D-Arg32, Lys33¿]r/hCRF(4-41). Labelled agonists such as (cyclo 30-33)[I?125Tyr0, D-Phe12, Nle21,38, Glu30, D-His32, Lys33¿]r/hCRF and (cyclo 30-33)[I?125D-Tyr3, D-Phe12, Nle21,38, Glu30, D-His32, Lys33¿]r/hCRF(3-41) are useful in screening for more potent agonists.
摘要:
A permucous composition characterized by comprising Antago-3 or a physiologically acceptable salt thereof and a sucrose/fatty acid ester. The composition can serve as a pharmaceutical preparation which has the high permucous absorbability of physiologically active peptide Antago-3 and is unstimulative and stable for long.
摘要:
Peptides capable of inhibiting complement activation are provided. Methods of inhibiting complement activation and complement-mediated tissue injury using these peptides are also provided. In addition, a method of producing compositions capable of inhibiting complement activation using these peptides is provided, along with the peptide analogs and peptidomimetics produced by the method.
摘要:
A hepatitis B vaccine containing a peptide with an amino acid chain of at least six consecutive amino acids within the pre-S gene coded region of the envelope of hepatitis B virus. The vaccine being free of an amino acid sequence corresponding to the naturally occurring envelope proteins of hepatitis B virus and a physiologically acceptable diluent. The peptide being free or linked to a carrier. The carrier being a conventional carrier or a novel carrier including a lipid vesicle stabilized by cross-linking and having covalently bonded active sites on the outer surface thereon. Such novel carrier being useful not only to link the novel peptide containing an amino acid chain with amino acids within the pre-S gene coded region of the surface antigen of hepatitis B virus, but can also be used to bind synthetic peptide analogues of other viral proteins, as well as bacterial, allergen and parasitic proteins of man and animals. The peptides of the invention can be utilized in diagnostics for the detection of antigens and antibodies.
摘要:
The present invention contemplates a cyclic peptide that inhibits the binding between the VLA-4 receptor expressed on inflammatory leukocytes and the fibronectin CS-1 peptide expressed on endothelial cells that are involved in immunoinflammatory disease states. Pharmaceutical compositions containing a contemplated cyclic peptide and processes for treating immunoinflammatory conditions using a binding-inhibitory cyclic peptide are also disclosed.
摘要:
The oxytocin antagonist represented by formula (I) wherein (S-Pmp IS β,β-(3-thiapentamethylene)-β-mercaptopropionic acid, D-Trp is the D form of tryptophan, and Ile, Gln, Asn, Pen (Pen = penicillamine), Pro, and Arg are the L forms of isoleucine, glutamine, asparagine, proline and arginine, respectively. This compound can be administered to pregnant women to arrest premature labor while avoiding unwanted side effects due to antagonism of the antidiuretic hormone, vasopressin.
