Definition:An organic heteropentacyclic compound that is (5R)-5-ethyl-5-hydroxy-8-(quinolin-3-ylmethyl)-1,4,5,8-tetrahydrooxepino[3,4-c]pyridine-3,9-dione in which position 7 of the oxepinopyridine group has been joined to position 2 of the quinoline ring by a single bond. A semisynthetic analogue of camptothecin, it is an inhibitor of topoisomerase I.
