简介内容:K 41498 is a selective peptide antagonist targeting both corticotropin-releasing factor receptor 2α (CRF2α) and CRF2β, demonstrating high affinity with Kis of and nM, respectively, in HEK293 cells expressing these human receptors. Its selectivity is evident as it exhibits a significantly reduced affinity for CRF1 receptor (Ki = 425 nM in HEK293 cells expressing the human CRF1 receptor). Additionally, K 41498, when administered intravenously at ?g/animal, effectively mitigates uroc
