摘要:Processes for the enzyme-catalyzed synthesis of triglycerides containing polyunsaturated fatty acids in which the synthesis is preceded by a pre-hydrolysis in which (a) C 1-4 alkyl esters of polyunsaturated fatty acids are completely or partly hydrolyzed in vacuo with continuous addition of water or are partly hydrolyzed in several stages without vacuum, (b) after the hydrolysis, the water is removed by separation or distillation and (c) the synthesis of the polyunsaturated fatty acids with glycerol in vacuo in the presence of an enzyme to form their triglycerides is carried out under low-water conditions, (d) the enzymes are removed from the triglyceride by separation or filtration and (e) the remaining fatty acids and/or possible residues of C 1-4 alkyl esters are removed from the triglyceride by distillation or refining; the pre-hydrolysis and the subsequent synthesis preferably being carried out as a one-pot process in the same reactor and in the presence of the same enzyme.

摘要:The invention relates to the fields of fatty substance chemistry, specifically of the ceramide-type compound synthesis. The invention resides substantially in the synthesis of ceramide-type compounds. Specifically, the aim of the invention is a new enzymatic synthesis method, comprising at least one amidification step and one esterification step, achieved through lipases, among fatty acids and/or esters thereof and amino alcohols. The resulting ceramide-type compounds can be used as cosmetic and/or pharmaceutical compositions, in particular as dermatological compositions in conjunction or in admixture with one or more suitable cosmetic and/or pharmaceutical excipients or carriers. The method has an interest particularly in the synthesis of active compounds useful in the fields of cosmetology and/or pharmacology and specifically of dermatology.

摘要:A SEDDS or SMEDDS or SNEDDS formulation for drug delivery of a lipophilic therapeutic agent, providing enhanced modulation of solubility, stability, absorption, metabolism, and/or pharmacokinetic profile of the therapeutic agent by formulation with a lipophilic surfactant, a hydrophilic surfactant, one or more solubilizers and, optionally, digestible oils, resulting in higher bioavailability of the therapeutic agent administered to a subject in need of such therapeutic agent. Also described are pharmaceutical compositions containing the formulations and methods of making and methods of using the formulations and pharmaceutical compositions. Formulations of the disclosure can be constituted to minimize the synthesis of dihydrotestosterone when the therapeutic agent includes testosterone or testosterone esters.
