Alkalmazás

Astressin has been used as a CRF-receptor antagonist to study its effects on the decrease in the Schaffer collateral-CA1 field potential induced by hypoxia/hypoglycemia (ischemia) in rat hippocampal slices.

Biokémiai/fiziológiai hatások

Astressin is a non-selective corticotropin releasing factor (CRF)-receptor antagonist. It potentially blocks CRF-induced adrenocorticotropic hormone (ACTH) release. Astressin effectively deceases delayed effects of chronic social isolation such as anxiety and fobial states in rats.

Peripheral activation of corticotropin-releasing factor receptor type 2 (CRF(2)) by urocortin 1, 2, or 3 (Ucns) exerts powerful effects on gastric function; however, little is known about their expression and regulation in the stomach. We investigated the expression of Ucns

Corticotrophin-releasing factor (CRF) plays a major role in coordinating stress responses. We aimed to test whether blocking endogenous CRF activity can prevent the stress-induced dilation of intercellular spaces in esophageal mucosa. Eighteen adult male rats were divided into 3 groups:
