Avanafil (dibenzenesulfonate)

Avanafil (TA-1790) dibenzenesulfonate is a potent and selective phosphodiesterase-5 (PDE-5) inhibitor with IC₅₀ values 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 dibenzenesulfonate activates NO/cGMP/PKG signaling-pathway to decrease loss in BMD, bone atrophy, and oxidative stress. Avanafil dibenzenesulfonate inhibits cyclic guanosine monophosphate (cGMP) hydrolysis and thus increases cGMP levels. Avanafil dibenzenesulfonate can be used for the research of erectile dysfunction and osteoporosis^[1][2][3]. In Vitro: Avanafil (TA-1790) dibenzenesulfonate (0.01-1000 µM) enhances by 45% for electrical field stimulation (1-20 Hz)-induced relaxation responses in corpus cavernosum strips from the diabetic group^[2]. In Vivo: Avanafil (TA-1790) dibenzenesulfonate (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) dibenzenesulfonate (10 µM; ICI; once, for 10 weeks) improves erectile responses in T2DM rats^[2].
