caprolactone	A epsilon-lactone that is oxepane substituted by an oxo group at position 2.	hexano-6-lactone
diflomotecan	An organic heteropentacyclic compound that is (5R)-8-[(6,7-difluoroquinolin-3-yl)methyl]-5-ethyl-5-hydroxy-1,4,5,8-tetrahydrooxepino[3,4-c]pyridine-3,9-dione in which position 7 of the oxepinopyridine moiety is joined to position 3 of the difluoroquinoine ring by a single bond. An E-ring modified camptothecin analogue that has greater lactone stability in plasma compared with other topoisomerase I inhibitors.	diflomotecan
homocamptothecin	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.	(R)-homocamptothecin
