                                    Eight monosaccharide analogs of the potent antitumor OSW saponins (2-9) were synthesized. One analog, 2-O-acetyl-aL-arabinopyranoside 3, showed antiproliferative activity against the Jurkat cells (IC50 = 0.078 mu M) comparable to that of the disaccharide derivative (1).
