体外研究

Vericiguat (0.01 μM to 100 μM) stimulates recombinant sGC concentration dependently, by 1.7-fold to 57.6-fold. When combined with the NO donor diethylamine/nitric oxide complex (DEA/NO), vericiguat and DEA/NO have a synergistic effect on the enzyme activity over a wide range of concentrations. At highest concentrations of vericiguat (100 μM) and DEA/NO (100 nM), the specific activity of sGC is 341.6-fold above baseline. Vericiguat stimulates the sGC reporter cell line concentration dependently, with an EC50 of 1005±145 nM. Vericiguat inhibits phenylephrine-induced contractions of rabbit saphenous artery rings, rabbit aortic rings, and canine femoral vein rings concentration dependently, with IC50 values of 798, 692, and 3072 nM, respectively. Vericiguat inhibits the U46619-induced contractions of porcine coronary artery rings concentration dependently, with an IC50 of 956 nM.

体内研究

Vericiguat (compound 24) (oral administration; 3 mg/kg, 10 mg/kg; once daily; 21 days) maintains heart and kidney function in a model of hypertension-induced end-organ damage in L-NAME-treated renin transgenic rats. Additionally,Vericiguat-treated group substantially reduces overall mortality when compared to the control group.

Animal Model:L-NAME-treated renin transgenic rats
Dosage:3 mg/kg, 10 mg/kg
Administration:Oral administration; 3 mg/kg, 10 mg/kg; once daily; 21 days
Result:Resulted in a significant attenuation of blood pressure increase, however the overall rise of blood pressure increase was not halted in the 3/10 mg/kg treatment groups.
Resulted a significant and dose-dependent reduction of heart hypertrophy, in both the right and left ventricle.
With respect to kidney damage, Vericiguat  Led to a significant reduction in kidney injury molecule Kim-1 and osteopontin expression which are used as biomarkers for renal injury and dysfunction.
Resulted in a significant and dose-dependent increase in survival rates. The rat survival rate was 70% and 90%, respectively in the 3 and 10 mg/kg qd treatment groups. In contrast, the survival rate in the placebo group was only 25% after 21 days.

动物实验

不同实验动物依据体表面积的等效剂量转换表(参考来源于公开文献
小鼠大鼠豚鼠仓鼠
重量 (kg)0.020.151.80.40.0810
体表面积 (m2)0.0070.0250.150.050.020.5
Km 系数36128520
动物 A (mg/kg) = 动物 B (mg/kg) × 动物 B的Km系数
动物 A的Km系数

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
