摘要:
Methods for treating Attention Deficit Disorder, Attention Deficit Hyperactivity Disorder, AIDS Dementia Complex and cognitive decline in HIV-AIDS while minimizing drug hypersensitivity, toxicity, side effects, euphoric effect, and drug abuse potential by administration of d-threo-methylphenidate or pharmaceutically acceptable salts thereof.
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.

In one aspect, the present invention is directed to methods for treating fatigue, neurobehavioral slowing and other cognitive disorders and defects due to cancers and treatments associated with cancers, and similar conditions. In a further aspect, the present invention is directed to methods for treating disorders related to menopause, including executive function defects. The methods involve the administration of a composition comprising D-threo methylphenidate that is substantially free of L-threo methylphenidate and of erythro forms of methylphenidate.

摘要:
Mixtures of enantiomeric D,L-threo 2-amino-3-hydroxy-3-phenylpropionic acids can be stereoisomerically enriched by contacting the mixture with a D-threonine aldolase. In a typical embodiment, D- and L-threo 2-amino-3-hydroxy-3-(4-methylsulfonylphenyl)propionic acid is treated with D-threonine aldolase to produce L-threo 2-amino-3-hydroxy-3-(4-methylsulfonylphenyl)propionic acid with a high ee. The benzaldehyde and amino acid formed from the D-threo isomer can be recycled.

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.
