TAK-438是钾竞争性的酸阻滞剂,能可逆的抑制H+/K+-ATPase,IC50为19 nM(pH 6.5)。
Information
Vonoprazan Fumarate (TAK-438) Vonoprazan Fumarate (TAK-438) is a novel P-CAB (potassium-competitive acid blocker) that reversibly inhibits H+/K+, ATPase with IC50 of 19 nM (pH 6.5), controls gastric acid secretion. Phase 3.
In vitro
TAK-438 is a pyrrole derivative with a chemical structure that is completely different from the P-CABs developed to date. TAK-438 inhibits gastric H+, K+-ATPase activity in a concentration-dependent manner. Under neutral conditions (pH 7.5), the inhibitory activity of TAK-438 is almost the same as that under weakly acidic conditions (pH 6.5). TAK-438 does not inhibit Na+, K+-ATPase activity even at concentration 500 times higher than their IC50 values against gastric H+,K+-ATPase activity. TAK-438 inhibits gastric H+, K+-ATPase in a K+-competitive manner with Ki of 3 nM.
In vivo
TAK-438 inhibits basal gastric acid secretion in a dose-dependent manner, and the ID50 value is 1.26 mg/kg . Intravenous administration of TAK-438 dose-dependently increases the pH of the gastric perfusate, and the increase in pH is sustained for 5 h after administration. At the 1 mg/kg dose, the pH plateaues 90 min after administration, and the highest pH value reached is 5.9. In addition, TAK-438 shows a potent and longer-lasting inhibitory effect on the histamine-stimulated gastric acid secretion in rats and dogs. TAK-438 shows significant antisecretory activity through high accumulation and slow clearance from the gastric tissue. TAK-438 is unaffected by the gastric secretory state, unlike PPIs.
