Astressin-B

Add article description

Astressin-B is a nonselective corticotropin releasing hormone antagonist that reduces the synthesis of adrenocorticotropic hormone and cortisol.^[1]

Quick Facts Identifiers, PubChem CID ...

It reduces the synthesis of adrenocorticotropic hormone and improves the sexual drive of rats under stressing conditions.^[2]

Astressin-B is able to delay the emptying of solid food in mice.^[3] Astressin-B can prevent the release of adrenocorticotropic hormone in mice due to shock, alcohol and endotoxemia.^[4]

Treatment with astressin-B caused the sudden growth of hair in mice bred for a propensity for stress.^[5]
