  • Patent number: 6479668
    Abstract: A method for producing pyrrolidine derivatives such as 3,4-epoxypyrrolodines, 3-pyrrolidols and the like, by oxidizing 3-pyrrolines with at least one peroxide in the presence of at least one acid is disclosed. The 3-pyrrolines are produced by deriving cis-2-butene compounds from cis-2-butene-1,4-diols and performing a cyclization between the cis-2-butene derivatives and at least one primary amine. The method may be performed as a one-pot synthesis and may be performed as a continuous reaction.

  • Patent number: 6458758
    Abstract: Compositions and processes to alleviate free radical toxicity are disclosed based on the use of nitroxides in association with physiologically compatible macromolecules. In particular, hemoglobin-based red cell substitutes are described featuring stable nitroxide free radicals for use in cell-free hemoglobin solutions, encapsulated hemoglobin solutions, stabilized hemoglobin solutions, polymerized hemoglobin solutions, conjugated hemoglobin solutions, nitroxide-labelled albumin, and nitroxide-labelled immunoglobulin. Formulations are described herein that interact with free radicals, acting as antioxidant enzyme-mimics, which preserve nitroxides in their active form in vivo. Applications are described including blood substitutes, radioprotective agents, imaging agents, agents to protect against ischemia and reperfusion injury, particularly in cerebral ischemia in stroke, and in vivo enzyme mimics among others.
