Avanafil (TA-1790) 是一种有效的选择性磷酸二酯酶-5 (PDE-5) 抑制剂,抑制 PDE-5、PDE-6、PDE-4、PDE-10、PDE-8、PDE-7、PDE-2 和 PDE-1 的IC50值分别为 5.2 nM、630 nM、5700 nM、6200 nM、12000 nM、27000 nM、51000 nM 和 53000 nM,。Avanafil 激活 NO/cGMP/PKG 信号通路,减少骨密度损失,骨萎缩和氧化应激。Avanafil 抑制环单磷酸鸟苷 (cGMP) 水解,从而提高 cGMP 水平。Avanafil 可用于勃起功能障碍和骨质疏松的研究。
生物活性 | Avanafil (TA-1790) is a potent and selectivephosphodiesterase-5 (PDE-5)inhibitor withIC50values of 5.2 nM, 630 nM, 5700 nM, 6200 nM, 12000 nM, 27000 nM, 51000 nM and 53000 nM for PDE-5, PDE-6, PDE-4, PDE-10, PDE-8, PDE-7, PDE-2 and PDE-1, respectively. Avanafil activates NO/cGMP/PKG signaling-pathway to decrease loss in BMD, bone atrophy, and oxidative stress. Avanafil inhibits cyclic guanosine monophosphate (cGMP) hydrolysis and thus increases cGMP levels. Avanafil can be used for the research of erectile dysfunction and osteoporosis[1][2][3]. |

体内研究 (In Vivo) | Avanafil (TA-1790) (10 mg/kg; p.o.; daily, for 30 d; male rat) increases angiogenesis in bone tissue via the activation of NO, cGMP and PKG (NO/cGMP/PKG) signaling-pathway and significantly decreases dexamethasone-induced loss in BMD, bone atrophy, and oxidative stress[1]. Avanafil (TA-1790) (10 μM; ICI; once, for 10 weeks) improves erectile responses in T2DM rats[2].
Animal Model: | Male rat model of glucocorticoid-induced osteoporosis (GIOP)[1] | Dosage: | 10 mg/kg | Administration: | Oral administration; daily, for 30 days | Result: | Decreased the level of eNOS, NO, PDE-5, PICP, MDA, CoQ10/CoQ10H and 8-OHdG/108dG. Increased the level of cGMP, PKG, Cortisol and CTCP. |
Animal Model: | Male rat model of glucocorticoid-induced osteoporosis (GIOP)[1] | Dosage: | 10 mg/kg | Administration: | Oral administration; daily, for 30 days | Result: | Increased right femur trabecular bone thickness and epiphyseal bone width. |
Animal Model: | Male T2DM Sprague Dawley rats[2] | Dosage: | 10 μM | Administration: | Intracavernous injection; once, for 10 weeks | Result: | Increased in ICP/MAP in response to nerve stimulation and increased total ICP values. |
