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

6-Amino-4-methoxy-2- (β-D-ribofuranosyl) -2H-pyrazolo[3,4-d]pyrimidine, a purine nucleoside analogue, exhibits widespread antitumor efficacy, particularly against indolent lymphoid malignancies. Its anticancer mechanisms include the inhibition of DNA synthesis and the induction of apoptosis, among others [1].
