标 题:Peptidic compounds, compositions comprising them and uses of said compounds, in particular cosmetic uses
发明人:PESCHARD OLIVIER; DOUCET ANNE; LEROUX RICHARD; MONDON PHILIPPE
权利人:SEDERMA SA
摘要:The peptidic compound comprises at least an aminoacid which is lysine, ornithine, diaminopropionic acid or diaminobutyric acid or a derivative of these aminoacids, on which a carboxylic acid is grafted via a peptidic bound on the nitrogen of the lateral chain, said carboxylic acid comprising a (poly)cycle or (poly)heterocycle. Preferably, the grafted carboxylic acid is an aminoacid or a derivative, in particular selected from, a proline, a hydroxyproline or pyroglutamic acid.The peptidic compound can stimulate the synthesis of the main molecules constituting the extracellular matrix of the skin, especially collagen 1 and 4 and elastin. It can be used for topical cosmetic treatment such as a global anti-aging treatment, or for specific activities, including anti-wrinkles, moisturizing, to improve the mechanical properties of the skin, firmness/tone/elasticity/flexibility, to increase density and volume of the skin, improve skin radiance, for a restructuring effect and/or to fight stretch marks.

摘要:A process for the preparation of a radionuclide imaging agent includes providing an imaging agent including a chelated place-holder metal; loading the imaging agent onto an acid stable stationary phase; replacing the chelated place-holder metal of the imaging agent loaded on the stationary phase with a replacement radioactive metal under mild reaction conditions; and eluting the imaging agent including the chelated replacement radioactive metal from the stationary phase to provide a radionuclide imaging agent suitable for positron emission tomography (PET) or single-photon emission computed tomography (SPECT). The imaging agent can include a targeting agent that is directly conjugated to the imaging agent or by means of a linker. The process may also apply to other metals that are non-radioactive but used as diluent metals or other metals that are strongly bound to DOTA.

标 题 :Solid-phase synthesis of novel 14-membered macroycles for high throughput screening
发明人:LANTER CAROLINA L; GUILES JOSEPH W; RIVERO RALPH A
权利人:ORTHO MCNEIL PHARM INC
摘要:The preparation of 14-membered macrocycles from a resin-bound orthogonally protected lysine residue is described. Reductive alkylation of the a-nitrogen followed by acylation with an Fmoc-aminoacid provides a protected dipeptide precursor. Removal of the Fmoc-group, acylation with a succinic anhydride, methyltrityl-group removal and macrocyclization provides the desired macrocycles, after TFA cleavage, in excellent yield and purity.
