| Description | SB-674042 is a potent and selective dual antagonist of the non-peptide orexigenic peptides OX1 and OX2 receptors, with IC50s of 3.76 nM and 531 nM, respectively.SB-674042 can be used for the treatment of depression. |
| In vitro | [(3)H]SB-674042 是 OX(1) 受体的特异性、高亲和力放射性配体。[(3)H]SB-674042 的特异结合在整个细胞和膜格式中都是饱和的。分析表明存在单一的高亲和力位点，其K(d)值分别为3.76+/-0.45和5.03+/-0.31 nM[1]。将共表达促醒素-1和CB1受体的细胞处理与促醒素-1受体拮抗剂 SB-674042 也导致两种受体重新定位到细胞表面。与 SB-674042 处理也减少了 CB1 受体激动剂对 ERK1/2 磷酸化的效力，且仅当两种受体共表达时发生[4]。 |
| In vivo | 在小鼠压力替代模型(SMA)中，以0.3 nM/0.3 μL的给药剂量，icv(脑室内注射) SB-674042 ，能够减少Stay动物的环境和提示性恐惧冻结反应[2]。 |
