标题 :Method for the catalysed synthesis of carboxamides from carboxylic acids and an amine
发明人：HEITMANN DENNIS; APPEL JÖRG; GRÄF INGO
权利人:CLARIANT INT LTD
摘要:The invention relates to a method for producing carboxamides of formula (1) by reacting at least one alkyl phenyl carboxylic acid of formula (2) with at least one secondary amine of formula (3), where R 1 represents an alkyl group having 1 to 20 carbon atoms, R 2 represents C 1 -C 24 -alkyl, and R 3 represents C 1 -C 24 -alkyl, in the presence of orthophosphoric acid as a catalyst, wherein the reactants are mixed in a molar ratio of 1:0.5 to 1:100, the catalyst is added in a quantity of 0.1 to 15.0 mol.% (in relation to the alkyl phenyl carboxylic acid), and the reaction mixture is heated to a temperature of 160°C to 300°C, at a pressure of 1 bar(a) to 20 bar(a). The purification of the reaction mixture is achieved via subsequent washing with water, phase separation and then a distillation of the organic product phase.

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.
