The invention provides novel nucleic acids and polypeptides, referred to herein as stresscopin 1 and stresscopin 2, which preferentially activate the CRH-R2 receptor over the R1 receptor. Stresscopins, analogs and mimetics, and related CRH-R2 agonists suppress food intake and heat-induced edema; but do not induce substantial release of ACTH. Stresscopin also finds use in the recovery phase of stress responses, as an anti-inflammatory agent, as a hypotensive agent, as a cardioprotective agent, and in the treatment of psychiatric and anxiolytic disorders. Stresscopin nucleic acid compositions find use in identifying homologous or related proteins and the DNA sequences encoding such proteins; in producing compositions that modulate the expression or function of the protein; and in studying associated physiological pathways.

A method whereby the blood pressure metabolism in an individual showing evidence of dysregulation is improved when that person receives an appropriate oral administration of (−)-hydroxycitric acid. The potassium salt of (−)-hydroxycitric acid is a preferred form of the compound, followed by the sodium salt, then by the amide and other derivatives of the acid. The regulation of blood pressure levels over any given period of time may be improved with a controlled release form of (−)-hydroxycitric acid. Controlled release can be used to provide a sustained and modulated amount of the active to the body as desired and therefore regulate the use of the compound as a hypotensive agent.
