Teratogens
An agent that causes the production of physical defects in the developing embryo. (See all compounds classified as Teratogens.)
Male Sprague-Dawley rats were given a single ip injection (45 mg/kg) of radiolabeled 1-methyl-2-pyrrolidone. Plasma levels of radioactivity and cmpd were monitored for six hr and the results suggested a rapid distribution phase which was followed by a slow elimination phase. The major amount of label was excreted in the urine within 12 hr and accounted for approximately 75% of the labelled dose. ...

This study evaluated the toxicokinetics of N-((14)C)methylpyrrolidone (((14)C)NMP) after intravenous administration (0.1, 1, 10, 100, and 500 mg/kg, in saline solution) or topical application (20 and 40 uL/sq cm; 10 sq cm, neat) in haired male Sprague-Dawley rats. Whatever the dose, unchanged NMP was intensively distributed into the body with a volume of distribution of 69% of body weight. After this phase, unchanged NMP declined almost linearly with time for 3 to 4 hr after administration and then followed a mono-exponential function (t1/2 = 0.8 hr) for the three lowest doses. The maximal plasma level of 5-hydroxy-N-methylpyrrolidone (5-HNMP), the main metabolite, was reached 4 to 6 hr later for the three lowest doses and 8 to 24 hr later for the highest doses. These findings indicate that the elimination of NMP is governed by a saturable metabolism process. The Michaelis-Menten parameters estimated from plasma levels of unchanged NMP were 2 mM and 3.8 mg/hr, respectively. Between 4 and 10% of the administered doses were excreted in the urine as unchanged NMP. Urinary clearance of NMP (0.03 to 0.07 mL/min) indicates intensive tubular reabsorption. 5-HNMP was the main urinary metabolite and accounted for 42 to 55% of the administered doses. Its maximal urinary excretion occurred between 4 and 6 hr after administration of the three lowest doses and between 8 and 24 hr for the two highest doses. Urinary clearance (0.9 to 1.3 mL/min) was compatible with renal elimination by simple glomerular filtration.

Metabolism studies were performed using (14)C and tritium labeled N-methyl-2-pyrrolidinone in the rat. Male Sprague-Dawley rats were injected with labeled or unlabeled N-methyl-2-pyrrolidinone at 45 mg/kg body weight. Urine, feces, expired air, and bile were collected at various times between drug administration and sacrifice. For pharmacokinetic studies, serial blood samples were analyzed at times between 30 minutes and 6 hours post injection. HPLC of plasma N-methyl-2-pyrrlidinone indicated a rapid distribution phase followed by a slow elimination phase with a half life of approximately 7 hours for the (14)C and 10 hours for the tritium isotope. Urinary excretion accounted for approx 70% of the total dose within 12 hours, and a 2:1 ratio in the administered dose was maintained in the urine. The tissue distribution of the radiolabeled isomers showed similar patterns. The rank order of tissue accumulation from highest to lowest concentration was liver, intestine, testes, stomach, kidneys, lungs, brain, heart, pancreas, and spleen. The bladder, thyroid, and thymus showed minimal N-methyl-2-pyrrolidinone levels.

Six male volunteers were exposed for eight hours on four different days to 0, 10, 25, and 50 mg/cu m N-methyl-2-pyrrolidone. ... N-Methyl-2-pyrrolidone was absorbed through the respiratory tract and readily eliminated from the body, mainly by biotransformation to other compounds. ...

The aim was to study the metabolic pathway for N-methyl-2-pyrrolidone in humans. Three healthy male volunteers were administered 100 mg N-methyl-2-pyrrolidone orally. All urine was collected during nine consecutive days. The identification and quantification of the metabolites were performed by gas chromatography/mass spectrometry (GC/MS). N-Methyl-2-pyrrolidone, 5-hydroxy-N-methyl-2-pyrrolidone (5-hydroxy-N-methyl-2-pyrrolidone), N-methylsuccinimide, and 2-hydroxy-N-methylsuccinimide were found in urine. The mean excreted fractions for N-methyl-2-pyrrolidone, 5-hydroxy-N-methyl-2-pyrrolidone, N-methylsuccinimide, and 2-hydroxy-N-methylsuccinimide were 0.8%, 44%, 0.4%, and 20%, respectively. There was no conjugation with glucoronic acid or sulfate or either 5-hydroxy-N-methyl-2-pyrrolidone or 2-hydroxy-N-methylsuccinimide. One-third of the orally dosed N-methyl-2-pyrrolidone was not recovered in urine as either N-methyl-2-pyrrolidone, 5-hydroxy-N-methyl-2-pyrrolidone, N-methylsuccinimide, or 2-hydroxy-N-methylsuccinimide. The half-lives for 5-hydroxy-N-methyl-2-pyrrolidone, N-methylsuccinimide, and 2-hydroxy-N-methylsuccinimide in urine were approximately 4, 8, and 17 hr, respectively.

A method for determination of N-methylsuccinimide and 2-hydroxy-N-methylsuccinimide in human urine and of N-methylsuccinimide in human plasma was developed. N-Methylsuccinimide and 2-hydroxy-N-methylsuccinimide are metabolites of the ... organic solvent N-methyl-2-pyrrolidone. ... The method is applicable for analysis of urine and plasma samples from workers exposed to N-methyl-2-pyrrolidone.

This study described the isolation and identification of the major urinary metabolite of N-methylpyrrolidinone in the male Sprague-Dawley-rat following intravenous administration. The rats were injected via the tail vein with either unlabeled N-methylpyrrolidinone or (14)C labeled N-methylpyrrolidinone at 45 mg/kg. Urine was collected during 0 to 12, 12 to 24, and 24 to 48 hours after dosing and analyzed by gas chromatography/mass spectrometry. Thermospray liquid chromatography/mass spectrometry was performed on samples purified using high performance liquid chromatography method. The major metabolite correlated with 5-hydroxy-N-methylpyrrolidinone based on thin layer chromatography and mass spectral comparisons with an authentic sample.
