  • Patent number: 11780833
    Abstract: Compounds are provided herein which are emetine derivatives that can be used as prodrugs which selectively undergo activation to release emetine in specific cellular conditions. In one aspect, a blocking group is incorporated onto the emetine molecule by the derivization of the N2?-position with moieties that can be selectively removed by hydrolysis in the cancer/tumor microenvironment. Such compounds are less cytotoxic than emetine and are substantially inactive in non-cancerous cells. In one aspect, the compounds described herein can be used for the treatment of metastatic and non-metastatic cancers, including, for example, breast cancer, prostate cancer, lung cancer, and leukemia.

  • Patent number: 8952156
    Abstract: A process is disclosed for separating the output from the reaction of EDDN or EDMN with hydrogen in the presence of THF, a catalyst, TETA or DETA, water, and optionally organic compounds having higher and lower boiling points than TETA or DETA. Hydrogen is removed, and the output is supplied to a distillation column DK1 in which an azeotrope, optionally comprising organic compounds with a boiling point lower than TETA or DETA, is removed from the top. A product comprising TETA or DETA is removed from the bottom and passed into a distillation column DK2, removing THF. A stream comprising TETA or DETA passes from the bottom of DK2. The DK1 azeotrope is condensed. Phase separation is induced by the addition of an organic solvent essentially immiscible with water, and the mixture is separated. The organic phase is recycled into DK1 and the water phase is discharged.

  • Patent number: 8637709
    Abstract: Preparing a primary amine by alcohol amination of alcohol with ammonia and elimination of water includes reacting, in a homogeneously catalyzed reaction, a mixture of alcohol, ammonia, nonpolar solvent, and catalyst, in a liquid phase, to obtain a product mixture. The process then includes phase separating the product mixture into a polar product phase and a nonpolar product phase, and separating off the nonpolar product phase. At least some of the nonpolar phase returns to the homogenously catalyzed reaction. The process further includes separating off amination product from the polar product phase. At least some of the catalyst is in the nonpolar phase, and the catalyst accumulates in the nonpolar phase.
