Common structural features found in thiazolidinedione PPARy agonists and related compounds. replace the thiazolidinedione ring. The a-sub-stituted carboxylic acids are often highly potent, but may not be selective for PPARy. Thus compound 16 has similar potency 195 in functional transactivation assays for both PPARa and -y EC50 PPARa 13 nM, PPARy 4 nM , whereas farglitazar 17 is highly selective 190 for PPARy EC50 PPARct 450 nM, PPARy 0.35 nM . Neither 16 nor 17 has significant...

Ulcer Disease

Peptic ulcers arise because of an imbalance of acid-secretory mechanisms and mucosal-pro-tective factors, and the rationale for their treatment is aimed at restoring that balance. The loss of balance between acid secretion and mucosal-protective factors varies among peptic ulcer types. In type I ulcers, which occur high in the stomach, acid hypersecretion is not necessarily evident, suggesting the importance of impaired mucosal-protective factors in this clinical setting. Type II ulcers, in...

Info

Channels, thus depolarizing the cell. The change in membrane potential results in the opening of voltage-gated Ca2 channels and an increase in intracellular Ca2 , which triggers insulin release. Sulfonylureas, by block-ingpotassium current through the KATP channel, produce the same effect. The Katp channel is composed of two protein subunits in a ratio of 4 4. One subunit, termed Kir6.2, is a member of the inward rectifying potassium channel family. The other regulatory subunit, SURl, belongs...

Reversible Proton Pump Inhibitors

The effectiveness of clinically available PPIs relies on the number of active pumps at any one time and the recovery of pumps after biosynthesis. The prolonged suppression of gastric acid secretion produced by both H2-recep-tor antagonists and PPIs produces extended periods of hypergastrinemia, which has been associated with the formation of precancerous changes in human gastric mucosa and gastric in long-term animal studies. In fact, the development of omeprazole, a protonpump inhibitor, was...

Hormones and Neurotransmitters Regulating the Secretion of Gastric Acid

Physiology Gastric Acid Secretion

The acid-secretingoxyntic cell, or parietal cell, I is the main cell type in the gastric gland. Chief , cells pepsinogen-secretingcells , mucus cells, s and D-cells somatostatin-secreting cells are also found within gastric glands. Somatostatin, released from fundic D-cells, inhibits the release of acid secretion from the parietal cell. These specialized cells are in close proximity to parasympathic nerve endings and neural inputs are able to regulate hormone release 10 .The release of HA from...
