N-methylproline

(2S)-1-methylpyrrolidin-1-ium-2-carboxylate

C6H11NO2 (129.0789746)


N-Methyl-L-proline, also known as N-methyl-L-proline, (2S)-1-methylpyrrolidine-2-carboxylic acid, hydric acid, or monomethyl proline, is classified as a proline or a proline derivative. It is not naturally produced by humans and can only be obtained from the diet. In particular, it is a metabolically inert cell protectant found in many plants and is used by plants to protect against extremes in osmolarity and growth temperatures. N-Methyl-L-proline is found in the fruit juices of yellow orange, blood orange, lemon, mandarin, and bitter orange (PMID: 21838291). N-methylproline is an L-proline derivative obtained by replacement of the amino hydrogen by a methyl group. It has a role as a plant metabolite and a human metabolite. It is a L-proline derivative and a tertiary amino compound. It is a tautomer of a N-methylproline zwitterion. An L-proline derivative obtained by replacement of the amino hydrogen by a methyl group. Hygric acid (N-Methyl-L-proline) is a proline analogue found in the citrus juices and the juice of bergamot[1].

   

Pipecolic acid

Pipecolic acid, 14C-labeled CPD, (+,-)-isomer

C6H11NO2 (129.0789746)


Pipecolic acid is a metabolite of lysine found in human physiological fluids such as urine, plasma and CSF. However, it is uncertain if pipecolic acid originates directly from food intake or from mammalian or intestinal bacterial enzyme metabolism. Recent studies suggest that plasma pipecolic acid, particularly the D-isomer, originates mainly from the catabolism of dietary lysine by intestinal bacteria rather than by direct food intake. In classic Zellweger syndrome (a cerebro-hepato-renal genetic disorder, OMIM 214100) pipecolic acid accumulate in the plasma of the patients. It is known that plasma pipecolic acid levels are also elevated in patients with chronic liver diseases. Pipecolic acid is moderately elevated in patients with pyridoxine-dependent seizures and might therefore be a possible biochemical marker for selecting candidates for pyridoxine therapy (Plecko et al 2000). Pipecolic acid was also elevated in CSF in these vitamin B6-responsive patients (PMID 12705501). Pipecolic acid is found to be associated with adrenoleukodystrophy, infantile Refsum disease, and peroxisomal biogenesis defect, which are also inborn errors of metabolism. Pipecolic acid is a biomarker for the consumption of dried and cooked beans. Pipecolic acid is a metabolite of lysine found in human physiological fluids such as urine, plasma and CSF.

Vigabatrin

Acid, gamma-vinyl-gamma-aminobutyric

C6H11NO2 (129.0789746)


Vigabatrin is only found in individuals that have used or taken this drug. It is an analogue of gamma-aminobutyric acid. It is an irreversible inhibitor of 4-aminobutyrate transaminase, the enzyme responsible for the catabolism of gamma-aminobutyric acid. (From Martindale The Extra Pharmacopoeia, 31st ed)It is believed that vigabatrin increases brain concentrations of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter in the CNS, by irreversibly inhibiting enzymes that catabolize GABA (gamma-aminobutyric acid transaminase GABA-T) or block the reuptake of GABA into glia and nerve endings. Vigabatrin may also work by suppressing repetitive neuronal firing through inhibition of voltage-sensitive sodium channels.
