N2 - Three new antineoplastic glycosides, phyllanthostatins 1 (2a), 2 (2c), and 3 (3a), as well as phyllanthoside (2b), have been isolated from the Central American tree Phyllanthus acuminatus Vahl. The phyllanthostatins 1 (2a), 2 (2c), and 3 (3a) and phyllanthoside (2b) structures were completely assigned by detailed analyses of spectral data (principally by 400-MHz NMR) and have been confirmed by X-ray crystallographic analyses of degradation products. In addition to inhibiting growth of the murine P388 lymphocytic leukemia, both phyllanthostatin 1 and phyllanthoside were found to markedly retard progression of the murine B16 melanoma. One of these unique glycosides, phyllanthoside (2b), is in preclinical development at the U.S. National Cancer Institute.
