摘要:An objective of the present invention is to develop commercially viable methods for the synthesis of 5-[2-phenylsulfony)ethyl]-1H-indole of Formule (II), where R 1 and R 2 are same or different and each independently represent a hydrogen, fluorine, or di(lower alkyl)amino, acyl, or alkoxy carbonyl or chlorine atom, or a lower alkyl, lower alkoxy, nitro, cyano, aminolower alkylamine group Formula (II). Another objective of the present invention is to convert the product Formula (II) to Formula (I) in high yields, where R 1 and R 2 are same or different and each independently represent a hydrogen, fluorine, or di(lower alkyl)amino, acyl, or alkoxy carbonyl or chlorine atom, or a lower alkyl, lower alkoxy, nitro, cyano, aminolower alkylamine group Formula (I). One of the first processes attempted was by reacting the indole derivative of Formula (III) with aryl vinyl sulphones of Formula (V) as shown in Scheme-III. Another process attempted was by reacting the aniline derivative of Formula (VI) with aryl sulphones of Formula (VII) as shown in Scheme-III. Scheme IV.

发明人：GARVEY DAVID S; GASTON RICKY D; LETTS L GORDON; DE TEJADA INIGO SAENZ; TAM SANG WILLIAM; WORCEL MANUEL
权利人:NITROMED INC
摘要:The invention describes novel nitrosated and/or nitrosylated prostaglandins, and novel compositions comprising at least one nitrosated and/or nitrosylated prostaglandin, and, optionally, at least one compound that donates, transfers or releases nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor, stimulates endogenous synthesis of nitric oxide or is a substrate for nitric oxide synthase, and/or at least one vasoactive agent. The invention also provides novel compositions comprising at least one prostaglandin and at least one S-nitrosothiol compound, and, optionally, at least one vasoactive agent. The prostaglandin is preferably a prostaglandin E 1 compound, more preferably alprostadil, and the S-nitrosothiol compound is preferably S-nitrosoglutathione. The invention also provides methods for treating or preventing sexual dysfunctions in males and females, for enhancing sexual responses in males and females, and for treating or preventing cerebrovascular disorders, cardiovascular disorders, benign prostatic hyperplasia (BPH), glaucoma, peptic ulcers or for inducing abortions.

摘要:Engineered articles have a wide variety of applications due to the ability to vary their properties by variations in the functionality of the layers in the article walls and in the material (if any) contained in the core of the article. In particular, articles of this type such as capsules are of significant interest for a number of applications especially in the medical field where they have found to have uses as vehicles for drug and vaccine delivery. In addition the capsules have potential applications as diagnostics and in bio sensing research. The present invention relates to an improved method of forming a film or network on a substrate from contacting said substrate with a polyphenol compound and a metallic cation or a mixture of metallic cations for less than 30 minutes, which method can be utilised for the rapid synthesis of articles of this type.

标 题 :Synthesis of kenyaite-type layered silicate material and pillaring of said material
发明人：VALYOCSIK ERNEST WILLIAM
权利人:MOBIL OIL CORP
摘要:A method for synthesizing a crystalline Kenyaite-type silicate comprises preparing a mixture comprising sources of alkali metal cations (AM), silica, a non-alkali metal (M) of valence n, water and an organic compound (R), selected from an alkylamine, a trialkylamine, a tetraalkylammonium compound and trimethylhexamethylene diamine, said alkyl having 1 to 12 carbon atoms, and said mixture having a composition, in terms of mole ratios, within the following ranges: SiO2/MmOn at least about 40, H2O/SiO2 5 to 200, OH-/SiO2 0 to 5, AM/SiO2 0.05 to 3, R/SiO2 0.01 to 3. The mixture is maintained under sufficient conditions to form crystals of the required silicate and the silicate crystals are then recovered. The invention further includes a method for pillaring the resulting layered silicate.
