HC 067047 is a selective antagonist of the TRPV4 channel. HC 067047 exhibits IC50 values of 48±6nM, 133±25nM and 17±3nM against human, rat, and mouse TRPV4 channels, respectively[1].
In vitro, HC 067047 (1μM; 5min) reduces mechanoactivated currents in Schwann cells[2]. HC 067047 (1μM; 30min) reversed the hypoxia/reoxygenation (H/R)-induced elevation of intracellular Ca2+ concentration ([Ca²⁺]ᵢ) and cell injury[3].
In vivo, HC 067047 (1mg/kg; 5 weeks; s.c.) prevented the development of mechanical, but not thermal cold allodynia in diabetic mice[4]. Treatment with the selective TRPV4 antagonist HC 067047 (5, 10 and 20mg/kg; i.p.) significantly attenuated myocardial ischemia/reperfusion (I/R) injury[5]. HC 067047 (10mg/kg; i.p.) exerts protective effects against RB-induced lung injury[6].

HC 067047是TRPV4通道的选择性拮抗剂,对人、大鼠和小鼠TRPV4的IC50分别为48±6nM, 133±25nM和17±3nM[1]。
在体外,HC 067047 (1μM; 5min)可抑制施万细胞中的机械激活电流[2];HC 067047 (1μM; 30min)能逆转缺氧/复氧(H/R)引起的细胞内钙离子浓度([Ca²⁺]ᵢ)升高及细胞损伤[3]。
在体内,HC 067047 (1mg/kg; 5周; 皮下注射)可预防糖尿病小鼠机械性痛觉异常的发生,但对冷痛觉异常无效[4];选择性TRPV4拮抗剂 HC 067047 (5, 10 and 20mg/kg; 腹腔注射)显著减轻心肌缺血/再灌注(I/R)损伤[5]。HC 067047 (10mg/kg; 腹腔注射)对辐射所致肺损伤亦具有保护作用[6]。
