... The concentrations of urine terephthalic acid(TPA) in rats after single oral administration in dose of 100 mg/kg bw were determined by high pressure liquid chromatography. ... The results showed that the first-order kinetics and two-compartment model were noted on the elimination of TPA. ... The excretion rates of TPA in urine were about 50%, 52% and 53% in 0-24 hr, 0-48 hr and 0-72 hr respectively after administration. TPA is well absorbed when given orally and rapidly eliminated via urine. Urine TPA at the end of work shift should be considered as a biomarker of exposure for the occupational workers.

Terephthalic acid is absorbed from the gastrointestinal tract and is excreted in the urine apparently unchanged. Dermal or ocular absorption is negligible.

The pharmacokinetics of (14)C terephthalic acid were determined in Fischer-344 rats after iv and oral administration. After iv injection, the plasma concentration-time data were fitted with a three-compartment pharmacokinetic model. The average terminal half-life in 3 rats was 1.2 + or - 0.4 hr, and the average volume of distribution in the terminal phase was 1.3 + or - 0.3 l/kg. Following administration by gavage, a longer terminal half-life was obtained, indicating that dissolution of (14)C TPA or absorption from the gut may have been partially rate limiting. Recovery of (14)C TPA in the urine following a bolus iv dose was 101 + or - 8%, indicating essentially complete urinary excretion of the compound. No evidence of metabolism of (14)C TPA was obtained by analysis of urine by high-performance liquid chromatography. (14)C TPA was transported to the fetus after administration of the compound to pregnant rats; the concentrations in fetal tissues were low relative to the corresponding maternal tissues. Neonatal rats exposed to 5% TPA in the diet of their dams did not develop calculi until the onset of self-feeding. TPA was rapidly excreted into urine after administration to rats, and excretory mechanisms in the dam provided an effective mechanism of defense against TPA-induced urolithiasis in neonatal rats.

By use of the Sperber in vivo chicken preparation method, infusion of radiolabeled terephthalic acid ([14C]TPA) into the renal portal circulation revealed a first-pass excretion of the unchanged compound into the urine. This model was utilized further to characterize the excretory transport of [14C]TPA and provide information on the structural specificity in the secretion of dicarboxylic acids. At an infusion rate of 0.4 nmol/min. 60% of the [14C]TPA which reached the kidney was directly excreted. An infusion rate of 3 or 6 mumol/min resulted in complete removal of [14C]TPA by the kidney. These results indicate that TPA is both actively secreted and actively reabsorbed when infused at 0.4 nmol/min and that active reabsorption is saturated with the infusion of TPA at higher concentrations. The secretory process was saturated with the infusion of TPA at 40 mumol/mn. The excretory transport of TPA was inhibited by the infusion of probenecid, salicylate, and m-hydroxybenzoic acid, indicating that these organic acids share the same organic anion excretory transport process. m-Hydroxybenzoic acid did not alter the simultaneously measured excretory transport of p-aminohippuric acid (PAH), suggesting that there are different systems involved in the secretion of TPA and PAH. The structural specificity for renal secretion of dicarboxylic acids was revealed by the use of o-phthalic acid and m-phthalic acid as possible inhibitors of TPA secretion. m-Phthalate, but not o-phthalate, inhibited TPA excretory transport, indicating that there is some specificity in the renal secretion of carboxy-substituted benzoic acids. TPA was actively accumulated by rat and human cadaver renal cortical slices.

(14)C-Labeled terephthalic acid may be both secreted and reabsorbed by the nephron, and when infused at 3 or 6 umol/min its excretion efficiency is comparable to that of p-aminohippuric acid and tetraethylammonium.

A Rhodococcus species was isolated from soil by enriching for growth with dimethyl terephthalate as the sole carbon source. The organism degraded dimethyl terephthalate by hydrolysis of ester-bonds to free terephthalic acid which in turn was metabolized through protocatechuate by an ortho-cleavage pathway.

The results showed that the first-order kinetics and two-compartment model were noted on the elimination of TPA. The main toxicokinetic parameters were as follows: Ka = 0.51/hr, half-life ka = 0.488 hr, half-life alpha = 2.446 hr, time to peak = 2.160 hr, Ku = 0.143/hr, half-life beta = 31.551 hr, Xu(max) = 10.00 mg. ...

(14)C-Terephthalic acid has a short elimination half-life (approximately 60-100 minutes) in the plasma; however, the apparent half-life was longer following administration by gavage.

/The aim of this study was/ to investgate the metabolism of terephthalic acid (TPA) in rats and its mechanism. Metabolism was evaluated by incubating sodium terephthalate (NaTPA) with rat normal liver microsomes, or with microsomes pretreated by phenobarbital sodium, or with 3-methycholanthrene, or with diet control following a NADPH-generating system. The determination was performed by high performance liquid chromatography (HPLC), and the mutagenic activation was analyzed by umu tester strain Salmonella typhimurium NM2009. Expression of CYP4B1 mRNA was detected by RT-PCR. The amount of NaTPA (12.5-200 uL /per/ L) detected by HPLC did not decrease in microsomes induced by NADPH-generating system. Incubation of TPA (0.025-0.1 mmol /per/ L) with induced or noninduced liver microsomes in an NM2009 umu response system did not show any mutagenic activation. TPA exposure increased the expression of CYP4B 1 mRNA in rat liver, kidney, and bladder. Lack of metabolism of TPA in liver and negative genotoxic data from NM2009 study are consistent with other previous short-term tests...
