Lubiprostone (What can't prostaglandins do?)

Yesterday, I discussed a laxative drug that works by drawing water into the intestines (and introduced you to a helpful chart to aid description of particularly ineffable bowel movements).

Here is a drug that works on the same principle, but indirectly - it induces your intestines to secrete ions, which, in turn, cause water to transfer to your intestines and induce bowel movements.

The drug is a prostaglandin - you may know these from drugs that inhibit the formation of certain prostaglandins, such as ibuprofen. As you can see, the class of hormones has a broad range of physiological effects.

It is impossible to cover all organ systems in detail over the course of just two lectures. Thus, we will stick only to the basics. Still, I want to emphasize how much organ systems work together, in concert, to maintain the homeostasis (and rheostasis) of the body. I'd also like to emphasize…

any derivatization procedure or without derivatization procedure either in negative or positive mode with ESI OR APCIfor the molecule of 15- HYDROXY LUBIPROSTONE in human plasma upto 1 pg level via LCMSMS or any information to achieve sensitivity.

That is a fetching molecule. Any chance of seeing a cyclooxygenase next?

Of course, for another synthetic prostaglandin E1, misoprostil, the bowel movement producing action is called a side-effect. I guess it all depends on the marketing.

any HPLC methods for analisys?
