Vardenafil dihydrochloride 是一种具有高选择性和口服活性的磷酸二酯酶 5 (PDE5) 抑制剂，IC50为 0.7 nM。Vardenafil dihydrochloride 对 PDE1、PDE6 的IC50分别为 180 nM 和 11 nM，对 PDE3、PDE4 的IC50>1000 nM。Vardenafil dihydrochloride 非竞争性地抑制环磷酸鸟苷 (cGMP) 水解，从而提高 cGMP 水平。Vardenafil dihydrochloride 可用于研究勃起功能障碍、肝炎、糖尿病等。
| 生物活性 | Vardenafil dihydrochloride is a selective and orally active inhibitor ofphosphodiesterase-5(PDE5), with anIC50of 0.7 nM. Vardenafil dihydrochloride shows inhibitory towardsPDE1,PDE6withIC50s of 180 nM, and 11 nM respectively, whileIC50s are >1000 nM forPDE3andPDE4. Vardenafil dihydrochloride competitively inhibits cyclic guanosine monophosphate (cGMP) hydrolysis and thus increases cGMP levels. Vardenafil dihydrochloride can be used for the research of erectile dysfunction, hepatitis, diabetes[1]-[6]. |

体外研究
(In Vitro) | Vardenafil dihydrochloride specifically inhibits the hydrolysis of cGMP by PDE5 with an IC50value of 0.7 nM[1].
Vardenafil dihydrochloride increases intracellular cGMP levels in the cavernosum tissue of the penis, thus results increasing the dilation of the body's sinuses and blood flow[3].

体内研究
(In Vivo) | Vardenafil dihydrochloride (0.03 mg/kg; i.v.) exhibits facilitator effects in rats with cavernous nerve injury[4].
Vardenafil dihydrochloride (0.17 mg/kg; i.v.; once daily; 7 d) protects liver against Con A–induced hepatitis, and decreases the expression of NF-κB and iNOS in hepatic tissue[5].
Vardenafil dihydrochloride (10 mg/kg; p.o.; once daily; 25 weeks) prevents the reduction of tissue cGMP levels and the increase in 3-NT generation in ZDF hearts[6].
| Animal Model: | Male rat (9-week-old) underwent surgery for laparotomy or bilateral cavernous nerve (CN) crush injury[4] | | Dosage: | 0.03 mg/kg | | Administration: | Intravenous injection | | Result: | Restored normal erectile responses with a combind administration of BAY 60-4552 (0.03, 0.3 mg/kg). |
| Animal Model: | Liver injury induced by Con A in male Swiss albino mice (20 ± 2 g)[5] | | Dosage: | 0.17 mg/kg | | Administration: | Intravenous injection; once daily, for 7 days; as a pretreatment | | Result: | Reduced the levels of serum transaminases and alleviated Con A-induced hepatitis. |
| Animal Model: | Male 7-week-old Zucker diabetic fatty (ZDF) rats (preserved ejection fraction, HFpEF)[6] | | Dosage: | 10 mg/kg | | Administration: | Oral gavage; once daily, for 25 weeks | | Result: | Improved myofilament function in diabetic rat hearts. |
