Enhancement of nasal salmon calcitonin absorption by lauroylcarnitine chloride in rats.[Pubmed:8860430]

Pharm Res. 1996 May;13(5):739-43.

PURPOSE: We investigated optimum formulation characteristics in the nasal absorption of salmon calcitonin (sCT) by incorporation of acylcarnitines. METHODS: Nasal sCT formulations were administered to anesthetized rats. Plasma calcium level was measured and pharmacological bioavailability (P.bioav) was calculated. RESULTS: Nasal sCT absorption was significantly enhanced by carnitines with acyl groups of 12 or more carbon atoms. Enhancement by lauroylcarnitine chloride (LCC) was observed at its critical micelle concentration and reached a plateau at the concentration of 0.1 percent. Optimal absorption was achieved at a molar ratio of LCC to sCT of 5:1. Enhancement was not influenced by osmolarity and maximum enhancement was obtained at pHs 3.1 and 4.0. CONCLUSIONS: The 12-carbon LCC was the strongest enhancer among acylcarnitines. Micelle formation played a key role in this enhancement effect.

Determination of acylcarnitines in urine of patients with inborn errors of metabolism using high-performance liquid chromatography after derivatization with 4'-bromophenacylbromide.[Pubmed:8222273]

Clin Chim Acta. 1993 Jul 16;216(1-2):53-61.

A high-performance liquid chromatographic method is presented for the determination of urinary acylcarnitines. After solid phase extraction on silica columns the acylcarnitines are converted to 4'-bromophenacyl esters with 4'-bromophenacylbromide in the presence of N,N-diisopropylethylamine. Complete derivatization was achieved at 37 degrees C within 30 min. The 4'-bromophenacyl esters were separated by high-performance liquid chromatography on a Hypersil BDS C8 reversed-phase column with a binary gradient containing varying proportions of acetonitrile, water and 0.1 M triethylamine phosphate buffer. Essentially baseline separation was obtained with a standard mixture containing 4'-bromophenacyl esters of carnitine and synthetic acylcarnitines of increasing chain length ranging from acetyl- to palmitoylcarnitine. The method was used to obtain urinary acylcarnitine profiles from patients with propionic, methylmalonic and isovaleric acidemia and with medium-chain and multiple acyl-CoA dehydrogenase deficiency. Quantification of the acylcarnitines was achieved using undecanoylcarnitine as internal standard.

Molecular basis of mitochondrial fatty acid oxidation defects.[Pubmed:1431593]

J Lipid Res. 1992 Aug;33(8):1099-110.

A dozen separate inherited disorders of mitochondrial fatty acid beta-oxidation have been described in humans. This represents about half of the potential sites for genetic error that can affect this important pathway of energy metabolism. As the characterization of these disorders at the clinical and biochemical levels has progressed rapidly, so has the delineation of the molecular defects that underlie them. The most commonly recognized disorder of beta-oxidation is medium-chain acyl-CoA dehydrogenase deficiency; a striking feature of this disorder is that there is a single point mutation that accounts for 90% of the variant alleles among patients with medium-chain acyl-CoA dehydrogenase deficiency. Molecular defects of other enzymes in the pathway have been identified, and it seems likely that a complete description of these defects at the molecular level is a realistic goal. In basic biological terms, such studies will lead to a better understanding of the genetic control exerted on this pathway. In clinical terms, they will lead to improved understanding of the molecular pathophysiology of these diseases and may well provide the necessary techniques to proceed with the screening of these disorders.

Urinary excretion of l-carnitine and acylcarnitines by patients with disorders of organic acid metabolism: evidence for secondary insufficiency of l-carnitine.[Pubmed:6441143]

Pediatr Res. 1984 Dec;18(12):1325-8.

Concentrations of l-carnitine and acylcarnitines have been determined in urine from patients with disorders of organic acid metabolism associated with an intramitochondrial accumulation of acyl-CoA intermediates. These included propionic acidemia, methylmalonic aciduria, isovaleric acidemia, multicarboxylase deficiency, 3-hydroxy-3-methylglutaric aciduria, methylacetoacetyl-CoA thiolase deficiency, and various dicarboxylic acidurias including glutaric aciduria, medium-chain acyl-CoA dehydrogenase deficiency, and multiple acyl-CoA dehydrogenase deficiency. In all cases, concentrations of acylcarnitines were greatly increased above normal with free carnitine concentrations ranging from undetectable to supranormal values. The ratios of acylcarnitine/carnitine were elevated above the normal value of 2.0 +/- 1.1. l-Carnitine was given to three of these patients; in each case, concentrations of plasma and urine carnitines increased accompanied by a marked increase in concentrations of short-chain acylcarnitines. These acylcarnitines have been examined using fast atom bombardment mass spectrometry in some of these diseases and have been shown to be propionylcarnitine in methylmalonic aciduria and propionic acidemia, isovalerylcarnitine in isovaleric acidemia, and hexanoylcarnitine and octanoylcarnitine in medium-chain acyl-CoA dehydrogenase deficiency. The excretion of these acylcarnitines is compatible with the known accumulation of the corresponding acyl-CoA esters in these diseases. In this group of disorders, the increased acylcarnitine/carnitine ratio in urine and plasma indicates an imbalance of mitochondrial mass action homeostasis and, hence, of acyl-CoA/CoA ratios. Despite naturally occurring attempts to increase endogeneous l-carnitine biosynthesis, there is insufficient carnitine available to restore the mass action ratio as demonstrated by the further increase in acylcarnitine excretion when patients were given oral l-carnitine.(ABSTRACT TRUNCATED AT 250 WORDS)
