1H-Pyrrolo3,2-fquinoline-2-carboxylic acid, 8-chloro-2,3,6,7,8,9-hexahydro-4-hydroxy-2-methyl-1-oxo-6-(5,6,7-trimethoxy-1H-indol-2-yl)carbonyl-, methyl ester, (2R,8S)-: Does not have an individual approval but may be used as a component in a product covered by a group standard. It is not approved for use as a chemical in its own right.

Chemical substances, produced by microorganisms, inhibiting or preventing the proliferation of neoplasms.

A class of drugs that differs from other alkylating agents used clinically in that they are monofunctional and thus unable to cross-link cellular macromolecules. Among their common properties are a requirement for metabolic activation to intermediates with antitumor efficacy and the presence in their chemical structures of N-methyl groups, that after metabolism, can covalently modify cellular DNA. The precise mechanisms by which each of these drugs acts to kill tumor cells are not completely understood. (From AMA, Drug Evaluations Annual, 1994, p2026)
