The adenine monophosphate (AMP) activated protein kinase (AMPK), is a heterotrimeric complex that is activated by an increase in the AMP/ATP ratio, and is considered to be a cellular energy sensor that contributes to regulate energy balance and caloric intake. AMPK is activated by LKB1 hinase and it can phophorylate several enzymes involved in anabolism to(More)
1. JB-9322 is a selective histamine H2-receptor antagonist with gastric antisecretory activity and mucosal protective properties. 2. The affinity of JB-9322 for the guinea-pig atria histamine H2-receptor was approximately 2 times greater than that of ranitidine. 3. In vivo, the ID50 value for the inhibition of gastric acid secretion in pylorus-ligated rats(More)
1. The histamine H2-receptor antagonistic activity and antisecretory and antiulcer effects of JB-9315 were studied in comparison with the standard H2 blocker ranitidine. 2. In vitro, JB-9315 is a competitive antagonist of histamine H2 receptors in the isolated, spontaneously beating guinea-pig right atrium, with a pA2 value of 7.30 relative to a value of(More)
