Indolepyruvate
The thiamin diphosphate (ThDP)-dependent enzyme indolepyruvate decarboxylase (IPDC) is involved in the biosynthetic pathway of the phytohormone 3-indoleacetic acid and catalyzes the nonoxidative decarboxylation of 3-indolepyruvate to 3-indoleacetaldehyde and carbon dioxide. (PMID:15835904)  In addition, the enzyme was compared with the phenylpyruvate decarboxylase from Azospirillum brasilense and the indolepyruvate decarboxylase from Enterobacter cloacae. (PMID:21501384) Indole-3-pyruvate is a microbial metabolite, urinary indole-3-pyruvate is produced by Clostridium sporogenes (PMID:29168502) and Trypanasoma brucei (PMID:27856732). Indolepyruvate, also known as indolepyruvic acid or (indol-3-yl)pyruvate, belongs to indolyl carboxylic acids and derivatives class of compounds. Those are compounds containing a carboxylic acid chain (of at least 2 carbon atoms) linked to an indole ring. Indolepyruvate is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Indolepyruvate can be found in a number of food items such as spelt, strawberry, gram bean, and oregon yampah, which makes indolepyruvate a potential biomarker for the consumption of these food products. Indolepyruvate exists in all eukaryotes, ranging from yeast to humans.

Cystathionine ketimine
D-cystathionine ketimine and L-cystathionine ketimine enhance superoxide generation by human neutrophils in a different manner. D-Cystathionine Ketimine enhanced seryl phosphorylation of 16. 5-kDa protein in human neutrophils, while L-Cystathionine Ketimine enhanced tyrosyl phosphorylation of 45-kDa protein.(PMID: 10049498). Among the cystathionine metabolites, cystathionine ketimine and N-acetyl-S-(3-oxo-3-carboxy-n-propyl) cysteine (NAc-OCPC) significantly enhanced the N-formylmethionylleucylphenylalanine (fMLP)-induced superoxide generation, but cystathionine, NAc-cystathionine, and cyclothionine did not enhance the superoxide generation. Cystathionine ketimine and NAc-OCPC also enhanced superoxide generation induced by opsonized zymosan (OZ) but not that induced by arachidonic acid (AA) and phorbol 12-myristate 13-acetate (PMA). Superoxide generation induced by cystathionine ketimine and NAc-OCPC was inhibited by genistein, an inhibitor of tyrosine kinase, and was enhanced by 1-(5-isoquinoline sulfonyl)-2-methylpiperazine (H-7), an inhibitor of protein kinase C.(PMID: 10708546) [HMDB] Cystathionine ketimine (CT) is a cyclic amino acid that was found to have a priming effect on superoxide generation in human neutrophils (PMID: 10708546). D-Cystathionine ketimine and L-cystathionine ketimine enhance superoxide generation by human neutrophils in two different manners. D-Cystathionine ketimine enhanced seryl phosphorylation of 16.5-kDa protein in human neutrophils, while L-cystathionine ketimine enhanced tyrosyl phosphorylation of 45-kDa protein (PMID: 10049498). Cystathionine ketimine was found in the urine of a cystathioninuria patient (PMID: 8373176).
