Abstract: 2, 4-Dihydropyrazole glucosides 3a-3c were prepared and tested for their antitumor activity. The structures of these compounds were established by 1 H and 13 C- NMR spectroscopy. Glucoside 3b shows an in vitro IC 50 value of 16.4 µM against proliferation of the human promyelotic leukemia (HL60) cell line.
