title: New sulphonamide and carboxamide derivatives of acyclic C-nucleosides of triazolo-thiadiazole and the thiadiazine analogues. Synthesis, anti-HIV, and antitumor activities. Part 2.
abstract: A new series of acyclic C-nucleosides 1',2'-O-isopropylidene-D-ribo-tetritol-1-yl)[1,2,4] triazolo[3,4-b][1,3,4]thiadiazoles bearing arylsulfonamide (5-8) and arylcarboxamide (9-12) residues have been synthesized under microwave irradiation. Thiadiazines 13-15 have been analogously prepared, and upon acid hydrolysis, afforded the free nucleosides 16-18. The new synthesized compounds were assayed against HIV-1 and HIV-2 in MT-4 cells. Compound 7 was also screened against a panel of tumor cell lines consisting of CD4 human T-cells.
