RT Journal Article SR Electronic T1 Comparative Inhibitory Action of D- and L-Tryptophan on the Effect of d-Lysergic Acid Diethylamide in Vitro JF Molecular Pharmacology JO Mol Pharmacol FD American Society for Pharmacology and Experimental Therapeutics SP 68 OP 77 VO 10 IS 1 A1 JEFFREY L. WINKELHAKE A1 EDWARD W. VOSS, JR. A1 DENNIS E. LOPATIN YR 1974 UL http://molpharm.aspetjournals.org/content/10/1/68.abstract AB The incorporation in vitro of d-[3H]lysergic acid diethylamide into secreted protein from hyperimmune rabbit lymphoid cells was inhibited by both D- and L-tryptophan. The inhibition was specific for tryptophan isomers and analogues. On the basis of these findings a pathway was formulated to describe the preliminary steps culminating in the covalent incorporation of lysergic acid diethylamide into synthesized protein.
