摘要:
A process for preparing N-hydroxyalkylaminomethylphosphonic acid or salts thereof which comprises contacting an alkanolamine, formaldehyde and a dialkyl phosphite in the presence of an alcohol under suitable reaction conditions to produce a reaction mixture, and hydrolyzing the reaction mixture under acidic or basic conditions. In one embodiment, the N-hydroxyalkylaminomethylphosphonic acid or salts thereof is catalytically oxidized to produce an N-phosphonomethylaminocarboxylic acid or salts thereof.
摘要:
Compositions containing certain indole-2-carboxylate compounds and derivatives are described as being therapeutically effective in treatment of CNS disorders resulting from neurotoxic damage or neurodegenerative diseases, particularly those CNS disorders resulting from ischemic events. Preferred compounds are of the formula ##STR1## wherein each of R.sup.5 and R.sup.6 is independently selected from hydrido, bromo, chloro and fluoro, and wherein each of R.sup.10 and R.sup.12 is independently selected from hydrido and lower alkyl, and pharmaceutically-acceptable salts thereof.
摘要:
An enteric coating composition including about 0.01% to about 10% resin and about 0.01% to about 10% polymer. The enteric coating composition may be applied to a substrate, such as a pharmaceutical, nutraceutical, fruit, vegetable, agricultural product, or industrial product, to form an enteric coating on the substrate. Also provided is a multiple-component system having a first component including a resin and a second component including a polymer, wherein mixing the first component and the second component forms an enteric coating composition having about 0.01% to about 10% resin and about 0.01% to about 10% polymer. Methods for coating a substrate with the enteric coating compositions are also provided.
摘要:
An improved process for synthesizing opiate or opioid analgesics and anesthetics, and intermediates thereof is provided. In particular, processes of synthesizing intermediates for use in the preparation of synthetic opiate or opioid compounds such as, for example, remifentanil, carfentanil, sufentanil, fentanyl, and alfentanil are disclosed. The preparation process requires fewer steps, and results in reduced costs and higher efficiency than processes known in the art for producing remifentanil and carfentanil.

摘要:
A film coating composition comprising a cellulosic polymer, an opacifying agent, and a fatty acid is disclosed herein. Also disclosed is a film coating composition comprising a cellulosic polymer, an opacifying agent, a plasticizing agent, and a polyol. The disclosed film coating compositions may be mixed with a solvent to produce a film coating suspension. The film coating suspension can be applied to a substrate, such as a nutritional supplement, pharmaceutical, tablet, capsule, softgel, granule, particle, food confectionary form, agricultural seed, and the like to form a film coating on the substrate. Methods of coating a substrate with the film coating suspensions are also provided.
摘要:
A process for preparing N-hydroxyalkylaminomethyl-phosphonic acid or salts thereof which comprises contacting an alkanolamine, formaldehyde and a trialkyl phosphite under suitable reaction conditions to produce a reaction mixture, and hydrolyzing the reaction mixture under neutral, acidic or basic conditions. In one embodiment, the N-hydroxyalkylaminomethylphosphonic acid or salts thereof is catalytically oxidized to produce an N-phosphonomethylaminocarboxylic acid or salts thereof.
