RT Journal Article SR Electronic T1 RENAL EXCRETION OF L-TYROSINE AND ITS DERIVATIVES JF Journal of Pharmacology and Experimental Therapeutics JO J Pharmacol Exp Ther FD American Society for Pharmacology and Experimental Therapeutics SP 257 OP 265 VO 134 IS 3 A1 K. C. Huang YR 1961 UL http://jpet.aspetjournals.org/content/134/3/257.abstract AB Studies of the renal excretion of L-tyrosine and eight of its derivatives have shown that the mono-substituted derivatives behave similarly to L-tyrosine, namely they were reabsorbed by the renal tubules. In contrast, the disubstituted derivatives of L-tyrosine were secreted by the tubules. 3,5-Diiodo-L-tyrosine was used to represent the group of disubstituted compounds on the studies with stop flow technique. It was found that the secretion of this compound was localized in the proximal section and could be blocked by the administration of probenecid.
