概要
Information
Naftopidil (KT-611) is a selectiveα1-adrenergic receptorantagonist withKiof 3.7 nM, 20 nM, and 1.2 nM for α1a, α1b, and α1d, respectively, used for the treatment of benign prostatic hyperplasia. In vitro
Naftopidil is selective for the alpha1d-adrenoceptor with approximately 3- and 17-fold higher affinity than for the alpha1a- and alpha1b-adrenoceptor subtypes, respectively. Naftopidil has growth inhibitory effect in androgen-sensitive and -insensitive human prostate cancer cell lines. Naftopidil induces p21(cip1) but not p27(kip1) in PC-3 cells. Naftopidil induces apoptosis in all the investigated malignant mesothelioma cells, and a similar effect is obtained with prazosin, another α1-adrenoceptor blocker. Naftopidil-induced reduction in cell viability is inhibited by GF109203X, while prazosin-induced in cell viability is less affected. Naftopidil, an alpha 1-adrenoreceptor antagonist produces a concentration-dependent inhibition ofcollagen-induced Ca2+ mobilization, maximum inhibition (22.9%) occurring with 40 mM Naftopidil. Naftopidil also inhibits the adrenaline-induced rise in [Ca2+]i in a concentration-dependent manner (30 mM doxazosin), significant inhibitions of platelet aggregation also being produced. Naftopidil (0.3, 1, and 3 μM) inhibits 5-HT-induced bladder contraction in a concentration-dependent manner. Naftopidil inhibits both the 5-HT(2A) and 5-HT(2) receptor agonists-induced bladder contractions. Naftopidil binds to the human 5-HT(2A) and 5-HT(2B) receptors with pKi values of 6.55 and 7.82, respectively.
In vivo
Naftopidil selectively inhibits the phenylephrine-induced increase in prostatic pressure compared with mean blood pressure in the anesthetized dog model. Naftopidil inhibits 5-HT-induced bladder contraction via blockade of the 5-HT(2A) and 5-HT(2B) receptors in rats. Cell Data
Naftopidil (KT-611) is a selective α1-adrenergic receptor antagonist with Ki of 3.7 nM, 20 nM, and 1.2 nM for α1a, α1b, and α1d, respectively, used for the treatment of benign prostatic hyperplasia.
