5-O-tert-Butyldiphenylsilyl-2,3-O-isopropylidene-D-lyxono-1,4-lactone

5-O-(tert-Butyldiphenylsilyl)-2,3-isopropylidene-D-ribonolactone is a purine nucleoside analog. Purine nucleoside analogs have broad antitumor activity targeting indolent lymphoid malignancies. Anticancer mechanisms in this process rely on inhibition of DNA synthesis, induction of apoptosis, etc[1].
