Oxanosine is a guanosine analog antibiotic isolated from the culture broth of Streptomyces capreolus MG265-CF3, which has antibacterial activity against Eschericia.coli K-12 and cell growth inhibitory activity against HeLa cells.1 Oxanosine is confirmed to be a competitive inhibitor of GMP synthetase and its Ki value is 7.4 x 10-4 M.2 Oxanosine (2 µg/ml) induce a reversion toward the normal phenotype of K-ras-transformed rat kidney cells by inhibiting inosine monophosphate (IMP) dehydrogenase.3 Oxanosine inhibits HIV-1 replication, its EC50 values is 7.0 µg/ml against CEM cells.4
