  • Patent number: 8658695
    Abstract: The inventors have discovered that the disodium salt of certain delivery agents has surprisingly greater efficacy for delivering active agents than the corresponding monosodium salt. Furthermore, the inventors have discovered that the disodium salts of these delivery agents form solvates with ethanol and hydrates with water. Preferred delivery agents include, but are not limited to, N-(5-chlorosalicyloyl)-8-aminocaprylic acid (5-CNAC), N-(10-[2-hydroxybenzoyl]amino)decanoic acid (SNAD), and sodium N-(8-[2-hydroxybenzoyl]amino)caprylate (SNAC). The invention also provides methods of preparing the disodium salt, ethanol solvate, and hydrate and compositions containing the disodium salt, ethanol solvate, and/or hydrate.

  • Publication number: 20130253061
    Abstract: The present application relates to a novel method of preparing L-threo-dihydroxyphenylserine (droxidopa). Specifically, the application is directed to a method of preparing droxidopa via a deprotection step that is an alternative to deprotection steps that have been previously disclosed. The new deprotection strategy is advantageous in that it avoids the need to use hydrogenolysis or hydrazine.
