6-Amino-4-hydrozino-2- (β-D-ribofuranosyl) -2H-pyrazolo[3,4-d]pyrimidine

6-Amino-4-hydrozino-2- (β-D-ribofuranosyl) -2H-pyrazolo[3,4-d]pyrimidine is a purine nucleoside analogue with broad antitumor activity, particularly effective against indolent lymphoid malignancies, working through mechanisms such as inhibiting DNA synthesis and inducing apoptosis, among others [1].
