  A series of novel and highly active antitumor agents, 9-hydroxyellipticine glycosides were stereoselectively synthesized in good yields by an improved condensation reaction between 9-acetoxyellipticine and peracylated glycosyl halides using cadmium carbonate, followed by the removal of acyl groups with methanolic ammonia.

  A series of ellipticine glycosides [2-N-glycosyl quaternary pyridinium salts of three ellipticines: ellipticine (1), 9-methoxyellipticine (2), and 9-hydroxyellipticine (4)] were stereoselectively synthesized in good yields by an improved condensation reaction between ellipticines [1, 2, and 9-acetoxyellipticine (3)] and protected (peracylated and perbenzylated) glycosyl halides with cadmium carbonate, followed by deprotection. These glycosides were preliminarily evaluated for their antitumor activity in the L1210 leukemia system. Twenty-six (53%) of the 49 glycosides tested were curative, and five [9-hydroxyellipticine L-arabinopyranoside (41b), D-lyxofuranoside (43a), L-lyxopyranoside (44b), D-xylofuranoside (49a), and L-rhamnopyranoside (56)] were selected for extended evaluation on the basis of their high levels of activity. The structure-activity relationships are discussed. The selected glycosides showed remarkable activity in six different murine tumor systems with excellent therapeutic ratios; their efficacy surpassed that of doxorubicin against three of these systems. On the basis of these results and ease of formulation, the two glycosides 41b (SUN4599) and 49a (SUN5073) were selected for further preclinical evaluation and possible clinical development.
