pentacyclic derivatives of camptothecin were synthesized and evaluated for in vitro cytotoxic activity against P388, HOC-21, and QG-56 and in vivo antileukemic activity against P388 in mice. Hexacyclic compounds which have an additional 5-, 6-, or 7-membered ring cyclized at positions 7 and 9 of camptothecin were prepared by intramolecular cyclization of pentacyclic camptothecin derivatives or Friedländer
A novel hexa-cyclic compound, a derivative of camptothecin, of the general formula: ##STR1## The compound is prepared from an aminoketone compound and a pyranoindolizine compound by the condensation-ring closing reaction. It is abundantly water-soluble, and has an excellent antitumor activity and a high degree of safety, and can be applied as an antitumor medicine for curing tumors of various kinds.
