Application
α1アドレナリン受容体のα1D とα1Aサブタイプ選択的アンタゴニスト，ナフトピジル
Naftopidil is an α1D and α1A subtype-selective α1-adrenoceptor antagonist. The α1-adrenergic receptor is a G protein-coupled receptor (GPCR) associated with the Gq heterotrimeric G-protein. The receptor consists of three subtypes, including α1A-, α1B-, and α1D-adrenergic. Naftopidil is subtype-selective for the α1D-adrenoceptor with approximately 3- and 17-fold higher affinity than for the α1A- and α1B-adrenoceptor subtypes, respectively. In Japan, naftopidil is used to treat lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH). Recently, it has been reported that naftopidil suppresses human prostate tumor growth. (The product is for research purpose only.)
