  • Patent number: 8168656
    Abstract: The presently disclosed subject matter provides derivatives of non-steroidal anti-inflammatory drugs (NSAIDs) that are characterized by substantially reduced cyclooxygenase inhibiting activity, yet retain the ability to interact with and modulate the activities of other polypeptides such as the class of peroxisome proliferators-activated receptors (PPARs) and ?-secretase. Also provided are methods of using the derivatives to treat pathological disorders.

  • Patent number: 8097750
    Abstract: The instability of carbamate-protected alkyl imines has greatly hampered the development of catalytic asymmetric Mannich reactions suitable for the synthesis of optically active carbamate-protected chiral alkyl amines. A highly enantioselective Mannich reaction with in situ generation of carbamate-protected imines from stable ?-amido sulfones catalyzed by an organic catalyst has been developed. This reaction provides a concise and highly enantioselective route converting aromatic and aliphatic aldehydes into optically active aryl and alkyl ?-amino acids.
