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.
I second this. Either ddg has come a long way with sesrch results or Google enshittified theirs to oblivion. Maybe it’s both. I only use Google search for really obscure stuff that ddg has a hard time fetching. And more often than not Google fails as well.
