Several 9-(2-C-cyano-2-deoxy-l-beta-D-arabino-pentofuranosyl)purine derivatives were tested against Kaposi's sarcoma-associated herpesvirus (KSHV)-infected primary effusion lymphoma (PEL) cells. The guanine derivative (2, CNDAG) as well as the 2-amino-6-substituted-purine derivatives 3, 4 and 5 inhibited KSHV-positive cell growth but showed no cytotoxicity against KSHV-negative cells at >15 muM concentrations. Therefore, it was found that compounds 2, 3, 4 and 5 showed selective cytotoxicity against PEL cells infected with KSHV.
