Modular, Gold-Catalyzed Approach to the Synthesis of Lead-like Piperazine Scaffolds
摘要:
Ring-opening of cyclic sulfamidates with propargylic sulfonamides yielded substrates for a gold-catalyzed cyclization to yield tetrahydropyrazines. Manipulation of the tetrahydropyrazines, by reduction or using multicomponent reactions, yielded piperazine scaffolds in which substitution of the carbon atoms was varied. Such scaffolds may have value in the synthesis of novel screening compounds with lead-like molecular properties.

Agents and methods for chemoprevention and treatment of neoplasia are described, the agents including a selective inhibitor of inducible nitric oxide synthase and a combination of a selective inhibitor of inducible nitric oxide synthase and an inhibitor of cylcooxygenase-2 in a pharmaceutical composition. The agents and methods are used for chemoprevention and treatment of neoplasia including colorectal cancer and other cancers affecting epithelial cells throughout the body. The agents can also be used to treat the fibrosis that occurs with radiation therapy, as well as adenomatous polyps, including those with familial adenomatous polyposis (FAP).

Opticallyactive 1-substituted taurines, a type of important sulfur analogues of naturally occurring amino acids, and their N-benzyloxycarbonyl-protected derivatives were synthesized from the corresponding opticallyactive β-amino secondary alcohols in three steps via N-protection with benzyl chloroformate, substitution with thiolacetic acid under Mitsunobu conditions, and oxidation with performic
