RT Journal Article SR Electronic T1 The Mode of Action of Levallorphan as an Inhibitor of Cell Growth JF Molecular Pharmacology JO Mol Pharmacol FD American Society for Pharmacology and Experimental Therapeutics SP 453 OP 472 VO 3 IS 5 A1 RICHARD GREENE A1 BORIS MAGASANIK YR 1967 UL http://molpharm.aspetjournals.org/content/3/5/453.abstract AB Levallorphan inhibits the synthesis of RNA, DNA, and protein by Escherichia coli. The drug was found to cause an immediate, dramatic decrease in the amount of intracellular ATP. Evidence is presented which suggests that the decrease in ATP concentration is a consequence of the stimulation of an ATPase. Similar results were obtained in HeLa cells treated with levallorphan.
