Streptomyces sparsogenes SN-2325 isolated from a soil sample collected in Hokkaido, was found to produce sparoxomycins A1 and A2, new modulators of proliferation of mammalian cells. Sparoxomycins A1 and A2 reverse the morphology of temperature-sensitive mutant Rous sarcoma virus-infected NRK cells (src(ts)-NRK cells) from the transformed phenotype to the normal phenotype at the permissive temperature.
