The antibiotics formycin and formycin B were isolated3 from Norcardia interforma and f~ und~-~ to be C-nucleosides which were isomeric with the naturally occurring nucleosides adenosine and inosine, respectively. These antibiotics are of considerable interest since they are C-nucleosides and belong to the same class of compounds as~ howdomycin,~ pseudouridine, 8 and pyra~ omycin.~ Formycin has demonstrated inhibition of Ehrlich ...
