摘要:
This invention provides methods and compositions for inducing weight loss and maintaining optimum weight comprising administering an agent that stimulates carnitine palmitoyl transferase-1 (CPT-1) activity to the patient in need, including human patients. These methods do not require inhibition of fatty acid synthesis. In particular, this invention provides methods for development of therapeutics that selectively enhance fatty acid oxidation, increase energy production, and reduce adiposity while preserving lean mass, through the pharmacological stimulation of CPT-1 activity. In a preferred mode, the agent is administered in an amount sufficient to increase fatty acid oxidation. In another preferred mode, the agent is administered in an amount sufficient to antagonize malonyl CoA inhibition of CPT-1. In yet another preferred mode, the agent is administered in an amount sufficient to increase malonyl CoA level.

This invention provides a method for inducing weight loss in an animal by administering to the animal a compound which reduces the expression and/or secretion of neuropeptide Y (NPY). The effect may be accomplished directly, indirectly, or humorally. Preferably, administration of this compound has the effect of increasing malonyl CoA levels in the animal. Compounds administered according to this invention may be inhibitors of fatty acid synthase (FAS), including substituted α-methylene-β-carboxyl-γ-butyrolactones, or inhibitors of malonyl Coenzyme A decarboxylase (MCD). Preferably, the compound is administered in an amount sufficient to reduce the amount and/or duration of expression and/or secretion of NPY to levels at or below those observed for lean animals. In another preferred embodiment, the administration will reduce expression and/or secretion to levels observed for fed or satiated animals; more preferably, administration will reduce the level of NPY below that of fed animals. In a particular embodiment, this invention provides a method for inducing weight loss in an animal by administering a compound which inhibits feeding behavior in the animal. The method is particularly useful for inducing weight loss in animals deficient in expression of the hormone leptin or animals resistant to the action of leptin.

摘要:
The invention relates to methods of screening to find compounds that are cytotoxic to tumor cells and methods of treating tumor cells using these compounds. In particular, the invention relates to methods of screening for compounds that inhibit mammalian mitochondrial fatty acid synthase (mmFAS) and methods of treating tumor cells using mmFAS inhibitors. This invention also provides methods for inhibiting or preventing cancer cell survival by the administration of mitochondrial fatty acid synthase (FAS) inhibitors. Specifically, this invention describes a method for prohibiting or delaying the development of cancer, the growth of cancer or invasion of cancer from pre-malignant (noninvasive) lesions, or metastasis of cancer based upon the findings that this method compromises energy balance in cancer cells, in turn compromising their basic functions and causing their cell death. Compositions of matter containing mitochondrial FAS inhibition activity are also provided, as well as applications based upon the requisite role of mitochondrial FAS in cancer cell homeostasis.
