Amino Acid Recognition

Three naphthalimide derivatives were synthesized with different anchoring groups to adjust the supramolecular interactions with carboxylato-pillar[5]arene. The complexes were used as indicator displacement assays for basic amino acids and diamines.

Nine amino acids with different chemical properties have been chosen to promote the formation of hydrogels based on the bolamphiphilic gelator A: three basic amino acids (arginine, histidine and lysine), one acidic amino acid (aspartic acid), two neutral aliphatic amino acids (alanine and serine) and three neutral aromatic amino acids (phenylalanine, tyrosine and tryptophan).

Kinetics Of

Human placental chorionic villi were incubated for 30 min with [3H]lysine or [3H]arginine and the distribution ratios (intracellular:extracellular concentrations) were determined. The ratios remained unchanged when Na+ in Earle's buffered salt solution was replaced with Li+. When Na+ was replaced with choline there was a significant increase is distribution ratios (lysine 1.34 +/- 0.33 v. 3.99 +/- 0.15, arginine 1.95 +/- 0.37 v. 5.05 +/- 1.16). Leucine, a neutral amino acid with a Na(+)-independent transport system, was unaffected by choline substitution. The distribution ratio for alanine, which is Na(+)-dependent, was reduced (2.50 +/- 0.41 v. 1.45 +/- 0.20). Two other quarternary amines, acetyl-beta-methylcholine and tetraethylammonium chloride (TEA) caused similar increases in the distribution ratios of the basic amino acids. Hordenine, a tertiary amine, was less effective and there was little or no effect with ephedrine, a secondary amine. The choline effect was first observable at concentrations of 105 mM. With TEA, there was a progressive increase in distribution ratios beginning at 29 mM. Lysine efflux was measured after incubation of villi with lysine in Earle's buffer or choline buffer. Lysine was rapidly released to the fresh medium with 25% more retained in choline-exposed villi. The amines may cause alterations in the kinetics of basic amino-acid transporters or may modify other aspects of placental physiology permitting an increase retention of the basic amino acids.

Stop Flow

Using the method of stop flow analysis an attempt was made to localize the process of amino acid reabsorption in the nephron of the dog. Special attention was given to the group of basic amino acids and cystine believed to share a common tubular transport mechanism. The evidence obtained in this study points clearly to the proximal segment as the site of intensive reabsorption of all amino acids investigated. During the infusion of arginine, lysine or ornithine, an increased excretion of two remaining basic amino acids plus cystine was observed, as a rule. Successful attempts were made to infuse cystine intravenously. The results of these experiments did provide the missing link for the hypothesis derived by Dent and Rose ( Quart. J. Med. 20: 205, 1951) concerning the common transport mechanism of arginine, ornithine, lysine, and cystine in the renal tubules. The functional cystinuria, which can be induced by saturating the common reabsorptive pathway with each of the above-mentioned amino acids, is fully reversible.

Extraits De Plantes

Folin-type resins used to purify plant extracts of basic amino acids that interfere with proline determination are not selective and partially retain this amino acid and the basic amino acids. Therefore, their use should be avoided, otherwise correction factors must be introduced. Modifications to another method allow a more rapid and precise estimation of proline.
