Palladium-catalyzed Sonogashira cross-coupling reactions of halo-purines 9-benzyl-6-chloropurine (2a), 9-benzyl-8-bromoadenine (2b), and 9-benzyl-2-chloroadenine (2c) with ethynylferrocene (1) gave the corresponding (ferrocenylethynyl)purines 3a-c in moderate to good yields. Catalytic hydrogenation of these alkynes over Pd/C afforded the respective saturated [2-(ferrocenyl)ethyl]purines 4a-c. The crystal structures 3a, 3b, 4a and 4b as determined by X-ray diffraction show interesting solid-state interactions, markedly different for purines 3a and 4a on one hand and adenines 3b and 4b that possess a free amino group on the other. Electrochemistry of electrochemically labelled purines 3 and 4 has been studied by voltammetry and cyclic voltammetry on platinum disc electrode and the experimental oxidation potentials were confirmed and explained by ionization potentials from theoretical DFT calculations. Several compounds of this series exhibited a considerable cytostatic effect.

Recently, we have reported the 8-hydroxyadenine derivatives (2-4) as a novel class of interferon (IFN) inducing agents. In the present study, a series of 8-hydroxyadenines, which possess various amino moieties at the adenine C(2)-position, were synthesized and evaluated for their ability to induce endogenous IFN in comparison to the known active agent, Imiquimod. Among the compounds prepared, compound 9o possessing a 2-methoxyethylamino group at C(2)-position of adenine was found to exhibit potent IFN inducing activity in vivo. Compound 9o induced IFN from the dosage of 0.1 mg/kg, which was 30-fold potent than that of Imiquimod, and showed a good oral bioavailability (F=81%).
