专利号:WO-0054773-A1 优先权日:1999-03-12 标题:Dopamine agonists in combination with nitric oxide donors, compositions and methods of use 发明人:GARVEY DAVID S 权利人:NITROMED INC; GARVEY DAVID S 摘要:The present invention is directed to novel compositions comprising at least one dopamine agonist in combination with at least one nitric oxide donor (i.e. compounds that donate, transfer or release nitric oxide, elevate endogenous levels of endothelium-derived relaxing factor, stimulate endogenous synthesis of nitric oxide or are substrates for nitric oxide synthase). The novel compositions may optionally comprise at least one therapeutic agent, such as, a vasoactive agent, an antimetic agent, and mixtures thereof. The dopamine agonist is preferably apomorphine. The present invention is also directed to methods for treating and/or preventing sexual dysfunctions and/or enhancing sexual responses in patients. In other embodiments, the present invention is directed to methods treating or preventing neurodegenerative diseases, mitochondrial diseases, spinal cord injury, central or psychostimulant addiction, senile dementia, circulatory disorders, cardiovascular disorders, hyperprolactinaemia or myopia. The compounds and/or compositions of the present invention can also be provided in the form of a pharmaceutical kit.
专利号:US-3679655-A 优先权日:1968-06-28 标 题:N,n-disubstituted aminoethylcarbamyl protecting groups for cysteine 发明人:JAGER GEORG; GEIGER ROLF 权利人:HOECHST AG 摘要:A METHOD OF PROTECTING THE SULFUR ATOM OF CYSTEINE N PEPTIDE SYNTHESIS BY REACTION WITH B-(N,N-DISUBSTITUTED)AMINOETHYL ISOCYANATE IN WHICH ONE SUBSTITUENT IS METHYL OR EHTYL AND THE OTHER IS BENZYLOXYCARBONYL, T-BUTYLOXYCARBONYL, OR ADAMANTYLOXYCARBONYL. FOR REMOVAL OF THE PROTECTIVE GROUP, THE PEPTIDE IS TREATED WITH A STRONG ACID TO FORM THE ACID SALT OF THE CORRESPONDING MONOSUBSTITUTED N-ETHYL OR N-METHYL AMINO COMPOUND AND THEN MADE ALKALINE TO LIBERATE THE AMINE. THE PROTECTIVE GROUP CLEAVES INTRAMOLECULARLY WITH FORMATION OF A METHYL OR ETHYL-SUBSTITUTED IMIDAZOLONE AND THE PEPTIDE IN WHICH THE CYSTEINE SULFUR ATOM IS PRESENT AS SULFHYDRYL.
