Novel monocyclic L- nucleoside compounds have general formula (I). Embodiments of these compounds are contemplated to be useful in treating a wide variety of diseases including infections, infestations, neoplasms, and autoimmune diseases. Viewed in terms of mechanism, embodiments of the novel compounds show immunomodulatory activity, and are expected to be useful in modulating the cytokine pattern, including modulation of Th 1 and Th 2 response.
A series of sugar-modified derivatives of oxanosine and its carbocyclic analogs were synthesized from natural oxanosine and (−)-2-azabicyclo[2.2.1]hept-5-en-3-one, respectively. Among nucleosides tested for anti-HIV activities in vitro, oxanosine 1, its 5′-monophosphate 9, and 2′-deoxyoxanosine 8 reduced the number of HIV particles in CEM cells to almost the same level as ddI.
