Phytic acid dipotassium salt is an endogenous metabolite that inhibits β-secretase 1 (BACE1).

Pyrrole-2-carboxylic acid (Minaline) was first identified as a degradation product of sialic acids, then as a derivative of the oxidation of the D-hydroxyproline isomers by mammalian D-amino acid oxidase. The latter relationship results from the lability of the direct oxidation product, A'-pyrroline-4-hydroxy-2-carboxylic acid, which loses water spontaneously to form the pyrrole. A similar reaction is catalyzed by the more specific allohydroxy-D-proline oxidase of Pseudomonas. In whole animal observations, pyrrole-2-carboxylate (PCA) ' was identified in rat or human urine after administration of the D-isomers of hydroxyproline, a finding ascribable to the action of D-amino acid oxidase. Urinary excretion of N-(pyrrole-2-carboxyl) glycine has been reported in a 5-year-old affected with type II hyperprolinemia; The child has mild developmental delay, recurrent seizures of the grand mal type and EEG alterations.

(R)-5-Oxopyrrolidine-2-carboxylic acid (D-Pyroglutamic acid) is a cyclic derivative of glutamic acid, physiologically present in mammalian tissues. It releases GABA from the cerebral cortex and exhibits anti-anxiety effects in a simple approach-avoidance conflict situation in rats. In clinical pharmacology experiments, it significantly shortens the plasma half-life of ethanol during acute intoxication.

2-Pyrrolidinone is a characteristic compound present in cabbage. It is the lactam cyclization product of γ -aminobutyric acid (GABA) and has anti-cancer properties.

3-Furfuryl 2-pyrrolecarboxylate, a chemical compound, is extracted from the root tuber of Pseudostellaria heterophylla.

5-Hydroxy-2-pyrrolidinone is a natural product of Buddleja, Loganiaceae. The catalog number is TN3117 and the CAS number is 62312-55-4. 5-Hydroxy-2-pyrrolidinone can be used as a reference standard.

4,5-Dibromo-1H-Pyrrole-2-Carboxylic Acid (4,5-Dibromo-2-pyrrolic acid) is a marine derived natural products found in Agelas oroides.

2-Pyrimidinamine, 4-(5-bromo-1H-indol-3-yl)- (Meridianin C) is a marine derived natural products found in Aplidium meridianum.
