Recognise molecular structure (methadone analogue?)

[26astr00]

I'm intrigued by this molecular structure found in a pharmacokinetics book.

No explanation what it might be, but it looks a lot like mathadone to me.

What might possible be the effects of such a molecule?

Most likely a pro-drug for methadone I think

That's just Phenytoin, a non-recreational anti-seizure drug.

Since it used to be a very common prescription drug, they used it as an example of how our body gets rid of foreign substances.
As you can see, it first attaches a hydroxyl group, making the drug slightly more polar and thus more water-soluble. On that hydroxyl, it will further attach a glucuronic acid residue, which comes with 3 hydroxyls and 1 carboxyl group - making the metabolite polar as hell. I like to call glucuronic acid our body's "cement shoes" - a drug that normally isn't water-soluble (and thus also not "urine-soluble") can easily be eliminated via the kidneys after turning it into a glucuronate.
