摘要:
CRF receptor antagonists are disclosed which have utility in the treatment of a variety of disorders, including the treatment of disorders manifesting hypersecretion of CRF in a warm-blooded animals, such as stroke. The CRF receptor antagonists of this invention have the following structure: including stereoisomers and pharmaceutically acceptable salts thereof, wherein n, m, A, B, C, R, R1, R2 and Ar are as defined herein. Compositions containing a CRF receptor antagonist in combination with a pharmaceutically acceptable carrier are also disclosed, as well as methods for use of the same
摘要:
Ligand inhibitors for increasing levels of free corticotropin-releasing factor (CRF) in the brain are disclosed. Such ligand inhibitors cause release of CRF from the CRF/CRF-bind protein complex. Administration of the ligand inhibitors provide improvement in learning and memory, result in decreased food intake and/or provide treatment for diseases associated with low levels of CRF in the brain, notably Alzheimer's disease.
摘要:
Antagonists of neurokinin A which are derivatives of naturally occurring neurokinin A in which the amide bond connecting the two amino acids on the carboxy terminal end is modified are described. The antagonism is confirmed using conventional competitive binding and biochemical assays as well as conventional physiological tests and the use of these derivatives in a variety of conditions in which neurokinin A is implicated is also described.
