一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
SKF38393 HCl(SKF38393)是多巴胺D1受体的选择性激动剂[1],IC50值为110 nM [2]。
有两种功能类型的多巴胺受体,D1和D2受体[3]。前额皮层(PFC)D1受体(D1R)的活化引起‘倒U型’剂量反应。太少或太多D1R的刺激可削弱空间工作记忆[4]。
6-OHDA减少了纹状体神经元中编码P物质和D1多巴胺受体的mRNA的特异性表达。随后每天注射SKF-38393逆转了这一还原效果。SKF-38393还增加了强啡肽的mRNA[5]。D1Rs激活环AMP依赖性蛋白激酶,刺激腺苷酸环化酶,调节神经元的生长和分化,并改变多巴胺D2受体介导的细胞活动和行为[3]。在96孔板测定中,MCF-7细胞的接种参与了乳腺癌的体外筛选过程。1天之后,用SKF 38393培养细胞2天。数据表明,SKF 38393显著地降低了MCF-7细胞的增殖。IC50值是0.1 +/- 0.03 μM[6]。
在麻醉、人为气息奄奄及加拉明处理的大鼠中,静脉给药SKF 38393显著地改变了多巴胺的细胞活性。在这些大鼠中,可观察到放电率的增加和减少[7]。
