Abstract:
The instant invention relates to a method of phosphorodiamidite production that comprises: (E1 ) preparing a purified solution of a dialkylamine in a polar solvent as follows: - the dialkylamine dissolved in a polar solvent is contacted with a quantity of phosphorus trihalide that is sufficient to react with the alcohol impurities contained in the dialkylamine but sufficiently low to leave a major part of the dialkylamine unreacted, whereby a mixture is obtained that contains the dialkylamine in the polar solvent and reaction products of the impurities with the phosphorous trihalide; - the unreacted dialkylamine and polar solvent present in the mixture obtained in step (E1.1.) are extracted from the solution S by their difference of volatility, typically by distillation, whereby the purified solution of the dialkylamine in the polar solvent is obtained; (E2) the purified solution of dialkylamine in a polar solvent as obtained in step (E1) is reacted with a phosphorus trihalide, whereby an intermediate compound is formed; (E3) the intermediate compound obtained in step (E2) is reacted with a hydroxyalkyl compound in the presence of a non-polar co-solvent.
Abstract:
Provided herein are prodrug compounds, their preparation and their uses, such as treating liver diseases or non-liver diseases via intervening in the molecular pathways in the liver. Novel prodrug compounds of eicosapentaenoic and docosahexaenoic acids, their preparation and their uses are described. Some embodiments are related to novel prodrug compounds that are absorbed in the intestine and taken up via the hepatic portal vein to the liver. Some embodiments are directed to the use of the prodrugs to change eicosapentaenoic and docosahexaenoic acids absorption routes. Another aspect includes the use of prodrugs to treat diseases that benefit from enhanced eicosapentaenoic and docosahexaenoic acids distribution to the liver and like tissues and cells, including but not limited to fatty liver, and metabolic and cardiovascular diseases where the liver is involved in the production and/or the homeostasis control of the biochemical end products, e.g. glucose, cholesterol, fatty acids, triglycerides, lipoproteins, and apolipoproteins.
Abstract:
Described herein are neutral prodrugs of phosphorus-containing inhibitors of farnesyl transferase that include one or more phosphate fragments or analogs of phosphate fragments. Analogs of phosphate fragments include various linkers other than oxygen connecting the phosphate fragment to the remaining portion of the drug, such as but not limited to linkers forming phosphoramidates, phosphonates, difluorophosphonates, phosphordiamidates, and the like.

Abstract:
The disclosure refers to cationic lipothiophosphoramidates for in vitro and in vivo gene delivery, to the use thereof for gene delivery, as well as to liposomes and lipoplexes comprising such cationic lipothiophosphoramidates and to a method for preparing such cationic lipothiophosphoramidates.
Abstract:
This invention provides a novel method for purifying synthetic oligomers comprising capping, polymerizing and separating any failure sequences produced during oligomer synthesis. Either the failure sequence or the full-length oligmer may be polymerized. Optionally, small molecule impurities may also be incorporated into the polymerized material. The invention provides novel capping agents having a polymerizable functional group. The invention also provides kits comprising at least one composition of the present invention.
