标 题 :Optimized synthesis of pregabalin and 4-aminobutane acid using an improved method for producing conjugated nitroalkenes
发明人：STUMPF MARCUS
权利人:K H S PHARMA HOLDING GMBH
摘要:The invention relates to an optimized synthesis of pregabalin and additional 4-aminobutane acids using an improved method for producing conjugated nitroalkenes. This is achieved by a nitro-aldol reaction of an aliphatic aldehyde with a nitroalkane in the presence of a suitable diamine directly followed by an elimination of the conjugated nitroalkene by adding an acid, a subsequent catalyzed asymmetrical 1,4-Michael addition of a suitable nucleophile, and a subsequent retro-Claisen reaction or a hydrolosis and decarboxylation with a concluding reduction to 4-aminobutane acid.

标题:Topical administration of catecholamines and related compounds to subcutaneous muscle tissue using percutaneous penetration enhancers
发明人：PERRICONE NICHOLAS V
摘要:Compositions for the topical treatment of sagging subcutaneous muscle and overlying cutaneous tissue contain an active ingredient exhibiting or producing catecholamine activity such as catecholamines and/or related compounds in a dermatologically acceptable carrier that contains at least one percutaneous penetration enhancer. Examplary catecholamines include adrenaline, norepinepherine, dopamine and their precursors; catecholamine precursors such as tyrosine and phenylalanine are preferred. Many embodiments, particularly those employing tyrosine and/or phenylalanine as a catecholamine precursor, further contain a neurotransmitter synthesis enhancer such as dimethylaminoethanol, and other co-factors such as vitamin B 6 and pantothenic acid or calcium pantothenate are included in the composition to enhance the action of the active ingredients. Other compounds that scavenge free radicals and antioxidants may also be added.
