Oh, the patent expired? No problem, we’ll just methylate the structure, see that it makes no difference and put it out on the market as a new drug. Or maybe take the active part of a racemic mixture and half the dosage. Same drug double the patent. Semisynthetic insulin is even worse in that regard.
