Anti-inflammatory activity of alpha-MSH(11-13) analogs: influences of alteration in stereochemistry.

abstract：:Cocaine- and amphetamine-regulated transcript (CART) is a neurotransmitter and hormone, involved in the regulation of e.g. food intake, body weight, reward and addiction, and stress response. CART has also been found to affect insulin secretion and beta cell morphology, both in vivo and in vitro. Furthermore, CART aff...
