7-HF produced a vasorelaxant effect on endothelium intact aortic ring pre-contracted with the standard vasoconstrictors i.e., phenylephrine (1 μM), high K+ (80 mM) and angiotensin II (5 μM) with EC50 value of 12.5 (09.31–14.67), 8.82 (6.52–10.73), and 13.8 μg/mL (9.93–15.26) respectively (Figure 9A), compared to the standard drug verapamil (Figure 9B). This evidence concerns the gene AGT and hydrops fetalis.
