Description

Product Description

K 41498 is a peptide antagonist of corticotropin-releasing factor receptor 2α (CRF_2α) and CRF_2β (K_is = 0.66 and 0.62 nM, respectively, in HEK293 cells expressing the human receptors).¹ It is selective for CRF_2α and CRF_2β over CRF₁ (K_i = 425 nM in HEK293 cells expressing the human receptor). K 41498 (1.84 µg/animal, i.v.) prevents hypotension induced by urocortin (Item No. 24745) in rats. Intrathecal administration of K 41498 (0.075-0.5 µmol/animal) decreases the mechanical paw withdrawal threshold in a rat model of nociception induced by complete Freunds adjuvant.²
