title: 9-(2-C-Cyano-2-deoxy-beta-D-arabino-pentofuranosyl)guanine, a potential antitumor agent against B-lymphoma infected with Kaposi's sarcoma-associated herpesvirus.
abstract: 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 (3, CNDAG), as well as the 2-amino-6-substituted-purine derivatives 4, 5, and 6, exhibited cell growth inhibitory activity against KSHV-infected cells, but showed no cytotoxicity against KSHV-negative cells at >15 microM concentrations. Therefore, it was found that compounds 3, 4, 5, and 6 showed selective cytotoxicity against PEL cells infected with KSHV.
