    摘要: Amines in which the amino group is on a secondary carbon atom which is chirally substituted can be enantiomerically enriched by the action of an omega-amino acid transaminase which has the property of preferentially converting one of the two chiral forms to a ketone. The process can be used to stereoselectively sythesize one chiral form from ketones substantially to the exclusion of the other. An aqueous solution of chiral amines after being brought into contact with an omega-amino acid transaminase and an amino acceptor is treated with a water-immiscible organic solvent, the aqueous and organic phases are separated, and the aqueous phase can be recirculated for further contact with the transaminase.

    摘要: This invention relates to compositions comprising thalidomide and another anti-cancer drug which can be used in the treatment or prevention of cancer. Preferred anti-cancer drugs are topoisomerase inhibitors. A particular composition comprises thalidomide, or a pharmaceutically acceptable salt, solvate, or clathrate thereof, and irinotecan. The invention also relates to methods of treating or preventing cancer which comprise the administration of a thalidomide and another anti-cancer drug to a patient in need of such treatment or prevention. The invention further relates to methods of reducing or avoiding adverse side effects associated with the administration of chemotherapy or radiation therapy which comprise the administration of thalidomide to a patient in need of such reduction or avoidance.
