Publication number: 20100022639Abstract: 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 ?-methylene-?-carboxyl-?-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.Type: ApplicationFiled: September 11, 2009Publication date: January 28, 2010Applicant: The Johns Hopkins University School of Medicine Licensing and Technology DevelopmentInventors: Thomas M.

Publication number: 20090124684Abstract: 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.Type: ApplicationFiled: November 6, 2008Publication date: May 14, 2009Applicant: The Johns Hopkins University School of Medicine Licensing and Technology DevelopmentInventors: Jagan N.

Publication number: 20020187534Abstract: This invention describes a method to kill cancer cells by acute elevation of cellular malonyl Coenzyme A (Malonyl CoA) which leads to apoptosis. Elevation of malonyl CoA may be induced by inhibition of fatty acid synthase (FAS), or by other manipulation of fatty acid metabolism tht does not involve inhibition of FAS. Alternatively, growth of tumor cells may be induced by a combination of effects including FAS inhibition in conjunction with other interventions which affect fatty acid metabolism, including inhibition of carnitine palmitoyltransferase-1 (CPT-1). Any combination of drugs which produces an analogous physiologic effect(s) may be expected to lead to the same effect on susceptible tumor cells. For example, combination therapy with drug(s) that inhibit the fatty acid synthesis by inhibiting acetyl CoA carboxylase (the first enzyme in the fatty acid synthesis pathway) and drug(s) that inhibit CPT-1 may be expected to induce apoptosis in tumor cells.Type: ApplicationFiled: May 10, 2002Publication date: December 12, 2002Inventors: Ellen S.

Patent number: 5981575Abstract: Weight loss was noted in nude mice treated with cerulenin, a non-competitive inhibitor of FAS. Sustained reduction of adipocyte mass in humans without toxicity would significantly impact disease prevention worldwide. Aside from psychological and self-esteem improvement, weight loss via reduction of adipocyte mass may: (1) ameliorate hyperglycemia associated with non-insulin-dependent diabetes mellitus thereby reducing diabetic complications such as arterial disease, blindness, cataracts, etc., (2) reduce hypertension, (3) reduce risk of coronary artery vascular disease and stroke, and (4) reduce the risk of other complications of massive obesity such as osteoarthritis, surgical complications, etc. There is also potential use in livestock and poultry to reduce the saturated fat content of meat products. Therefore FAS inhibitors are disclosed herein as novel agents for weight reduction. A family of compounds (.gamma.-substituted-.alpha.-methylene-.beta.-carboxy-.gamma.Type: GrantFiled: January 27, 1998Date of Patent: November 9, 1999Assignee: Johns Hopkins University, TheInventors: Francis P.
