Absolutely.
Piperazine-2,6-dione hydrochloride is a small research chemical built around a six-membered ring containing nitrogen atoms and two carbonyl groups.
On its own, it isn't a famous drug.
Its interesting story is what chemists can build from its molecular framework.
The piperazine-2,6-dione ring is related to the chemistry of bisdioxopiperazines—a family that includes dexrazoxane, a drug used in certain situations to help protect the heart during treatment with anthracycline anticancer drugs.
Researchers have used piperazine-2,6-dione as a starting point for making dexrazoxane analogues.
