The bulbs of Pancratium littorale collected in Hawaii were found to contain a new phenanthridone biosynthetic product designated pancratistatin (4a) that proved to be effective (38-106% life extension at 0.75-12.5 mg/kg dose levels) against the murine P-388 lymphocytic leukemia. Pancratistatin also markedly inhibited (ED50, 0.01 μg/ml) growth of the P-388 in vitro cell line and in vivo murine M-5076 ovary sarcoma (53-84% life extension at 0.38-3.0 mg/kg). An X-ray crystal structure determination of pancratistatin monomethyl ether (4c) and a detailed high resolution (400 MHz) nmr study of pancratistatin and its pentaacetate (4b) completed assignment of structure 4a. Companion antineoplastic constituents of P. littorale were found to be narciclasine (2c) and its 7-deoxy derivative (2a). The structure of 7-deoxynarciclasine (2c) was also confirmed by an X-ray crystallographic analysis.
