Abstract:
The present invention relates to compounds such as peptides which act as proteasome inhibitors. The compounds are covalently linked with a signal emitting compound or a precursor thereof, via an ester such as a sulfonic ester group for imaging of the inhibition of the proteasome. The compound is for use in the quantification of proteasomal inhibition, diagnosis and/or prevention and/or treatment of autoimmune diseases, cancer, neurodegenerative diseases, viral infections and/or diseases associated with inflammation. The invention further relates to methods to produce the compounds.
Abstract:
The present disclosure relates to compounds, compositions and methods for the treatment of diseases through inhibiting the activity of the transforming growth factor beta (TGF-&bgr;). More specifically, the disclosed compounds, compositions and methods are useful in the treatment of certain cancers (e.g. multiple myeloma, hematologic malignancies), diseases associated with excessive TGF-&bgr; activity including fibrosis, dermal scarring, immune dysfunction, and bone loss by inhibiting the conversion of latent TGF-&bgr; to active TGF-&bgr;. A method of preventing the activation of TGF-&bgr; in pathology is also provided, comprising administering an amount of the compounds sufficient to inhibit conversion of latent TGF-&bgr; to active TGF-&bgr; by thrombospondin 1 (TSP1), resulting in reduced TGF-&bgr; activity and reduced adverse effects such as fibrosis, bone loss, and immune dysfunction.
Abstract:
본 발명은 NF-κB의 p65 서브유닛으로부터 유래된 작은 펩타이드 단편(small peptide fragments) 및 이를 포함하는 약학 조성물 또는 화장료 조성물을 제공한다. 상기 펩타이드는 NF-κB의 전사 촉진 기능을 조절함으로써 NF-κB 억제 활성을 갖는다. 상기 펩타이드들은 NF-κB 활성에 의해 발현이 유도되는 다양한 염증 매개분자의 발현을 억제하고 백혈구의 혈관외유출을 억제함으로써 항-염증 활성을 갖는다. 특히, 상기 펩타이드들은 피부 염증 및 피부 노화에 대한 우수한 억제활성을 갖는다. 또한, 상기 펩타이드들은 혈관신생 및 암세포의 바닥막 침윤을 억제함으로써 암세포의 성장과 전이에 대한 억제 활성을 갖는다.

Abstract:
La présente invention concerne un peptide bifonctionnel apte à activer la synthèse de collagène et à inhiber la production de métallo-protéinases matricielles, ledit peptide présentant une séquence comportant trois parties peptidigues A, B et C : - la première partie peptidigue A correspondant à un hexapeptide répété au moins trois fois, ladite partie A étant apte à se lier à une protéine récepteur liant l'élastine pour stimuler la synthèse de collagène, la deuxième partie peptidigue B correspondant à un tétrapeptide apte à agir en tant qu'inhibiteur compétitif de la protéase urokinase et à être clivé par ladite protéase, et, la troisième partie peptidigue C correspondant à un tripeptide occupant au moins un site actif des métallo- protéinases matricielles pour permettre une inhibition desdites protéinases. La présente invention concerne encore une composition cosmétique et/ou pharmaceutique incorporant le peptide bifonctionnel -
Abstract:
Synthesis of compounds having varying degrees of conformational rigidity is obtained via a low cost, high yield and efficient synthetic reactions. The library of compounds is structurally diverse, having at least one or more chiral centers and providing large numbers of compounds having building block diversity and substantial scaffold diversity. The compounds further provide a novel method for obtaining candidate therapeutic agents for prevention, treatment or diagnosis of diseases.
