摘要:
The present invention relates to protein nanocages comprising a melanocyte-targeting moiety and pharmaceutical compositions comprising the protein cages as well as methods for treating or diagnosing hyperpigmentation disorders or other melanocyte-related disorders using the protein nanocages or pharmaceutical compositions. In the preferred embodiment, the protein nanocage is composed of Bacillus stearothermophilus E2 protein of pyruvate dehydrogenase multi-enzyme complex (E2), with a skin penetrating and cell permeating SPACE moiety, and a melanocyte-targeting moeity of alpha melanocyte stimulating hormone.
摘要:
ACTH analog compounds of the present invention include compounds comprising an ACTH peptide sequence with one or more structural modifications that can have one or more of the following preferred ACTH analog biological functions: (1) reduction of corticosteroid secretion by adrenal membrane in the presence of the ACTH analog compared to unmodified ACTH, (2) reduction of corticosteroid secretion by adrenal membrane in the presence of endogenous ACTH and (3) increased MC-2R binding affinity with reduced activation of the MC-2R receptor compared to unmodified ACTH binding to the MC-2R melanocortin. The ACTH analog compounds of the present invention are therefore useful for treatment or prevention of diseases and disorders related to ACTH, ACTH receptors or corticosteroid secretion, such as premature labor and Cushing's Disease.
摘要:
The invention relates to an agent for calming the sensation of pain, in particular in chronic inflammatory disorders, by the expression of endogenic, neuroendocrine peptides at the inflammation site. The invention relates in particular to the expression of POMC or CRF from locally injected DNA expression constructs, preferably covalently peptide-modified expression constructs.
摘要:
The present invention is concerned with modified biological peptides providing increased potency, prolonged activity and/or increased half-life thereof. The modification is made via coupling through an amide bond with at least one conformationally rigid substituent, either at the N-terminal of the peptide, the C-terminal of the peptide, on a free amino or carboxyl group along the peptide chain, or at a plurality of these sites. Those peptides exhibit clinical usefulness for example in treating states of insulin resistance associated with pathologies such as type II diabetes.
摘要:
The present invention provides novel cytokine restraining agents, which limit or control the biological activity of cytokines. The invention also provides pharmaceutical compositions comprising a cytokine restraining peptide and methods of administering the pharmaceutical composition to a subject. The invention further provides methods for using the novel peptides to restrain cytokine activity in a subject.

摘要:
Sont décrites des protéines de fusion ayant la formule (I): H2N-Z1-X-(Pro-Y-Gly)n-Pro-Z2-COOH, dans laquelle n 2, X et Y représentent chacun des 20 acides aminés déterminés par le code génétique, Z1 est une séquence d'acides aminés bactériens et Z2 est le peptide cible composé de n'importe quels acides aminés voulus du code génétique. Leur procédé de production et leur clivage enzymatique, afin de former les protéines eucariotiques désirées, sont également décrits.
摘要:
The parenteral administration of 8O-16O µg per kg body weight of substituted or unsubstituted fragments of ACTH (1-39) having formula ACTH (X-Y) wherein X is an integer from 1 to 5 and Y is an integer from 1O to 39 (provided that, when X is 1, Y is not 24) restores the normal blood pressure and respiratory frequence in a patient in serious shock conditions, particularly in hypovolemic shock.
摘要:
Les peptides chimériques décrits sont adaptés pour fournir des agents neuropharmaceutiques tels que des neuropeptides au cerveau par transcytose par l'intermédiaire d'un récepteur au travers de la barrière hémato-encéphalique. Les peptides chimériques comprennent un peptide qui est capable par lui-même de traverser la barrière hémato-encéphalique par transcytose à une vitesse relativement élevée. Le peptide transportable est conjugué à un neuropeptide hydrophyle qui est par lui-même transportable uniquement à une très faible vitesse dans le cerveau au travers de la barrière hémato-encéphalique. Le peptide chimérique résultant est transporté dans le cerveau à une vitesse beaucoup plus élevée que le neuropeptide seul, ceci dans le but de disposer de moyens efficaces pour introduire des neuropeptides hydrophyles dans le cerveau au travers de la barrière hémato-encéphalique.
