What is an opioid-induced bowel dysfunction with mu-opioid receptor agonists?
Homework Answers
Opioid - induced bowel dysfunction is a term mainly used to describe constipation, incomplete evacuation of bowel,bloating and gastric reflux is the most common adverse event associated with opiod use.Mu-opioid receptors are specifically responsible for opioid induced dysfunction resulting in reduced peristaltic movement and secretory actions.Mu-opioid receptors antagonist are specific medicine for Induced bowel dysfunction when laxatives fail.

Scientists at MN-Pharm Sci have identified a novel molecule with potent Mu-opioid receptor (MOR) agonist activity by using high throughput assays. Structurally, the molecule does not belong any of the known chemical classes. The affinity of the compound is 30-times higher at MORs compared to morphine with similar efficacy. The affinity of this molecule for recombinant human recombinant Kappa- and Delta-opioid receptors by 170– and 350–fold, respectively, lower than that observed at the recombinant human Mu-opioid receptors. The hydrophilic/lipophilic nature...

Drugs A, B, and C are Dopamine Receptor Agonists used to treat Parkinson’s disease. Drug A has an EC50of 30 mg/mL, Drug B has an EC50of 20 µg/mL, and Drug C has an EC50of 40 g/mL. Drug C is 50% less efficacious than Drugs A or B. Graph these drugs on a semi-log graded dose-response curve (all on one graph and label the axis). Can you determine the Kdof each of these drugs from the data (tell me why or why not too: HINT-look...

The three-dimensional structure of the delta-opioid receptor is shown to the left. 9. What secondary structural features can you see in the receptor? 10. The receptor penetrates through the cell membrane. Draw a lipid bilayer around the receptor oriented as you might expect it to pass through the membrane. I. Label where you would expect to find hydrophobic and polar amino acids.
