Cordycepin Inhibition of 3-Methylcholanthrene-Induced Transformation In Vitro

Abstract
Cordycepin (3-deoxyadenosine), an inhibitor of poly (a) synthesis, inhibited the induction of the endogenous type "C" RNA virus by 5-iodo-2''-deoxyuridine in a line of Fischer rat embryo cells (H43) grown in vitro. When continuously incorporated into the medium at those same concentrations, it protected the cells from transformation by the chemical carcinogen 3-methylcholanthrene.
