Pentoxifylline
Pentoxifylline is only found in individuals that have used or taken this drug. It is a methylxanthine derivative that inhibits phosphodiesterase and affects blood rheology. It improves blood flow by increasing erythrocyte and leukocyte flexibility. It also inhibits platelet aggregation. Pentoxifylline modulates immunologic activity by stimulating cytokine production. [PubChem]Pentoxifylline inhibits erythrocyte phosphodiesterase, resulting in an increase in erythrocyte cAMP activity. Subsequently, the erythrocyte membrane becomes more resistant to deformity. Along with erythrocyte activity, pentoxifylline also decreases blood viscosity by reducing plasma fibrinogen concentrations and increasing fibrinolytic activity. It is also a non selective adenosine receptor antagonist.

N1-(alpha-D-ribosyl)-5,6-dimethyl-benzimidazole
N1-(alpha-D-ribosyl)-5,6-dimethyl-benzimidazole is an intermediate in riboflavin metabolism. It is converted from N1-(5-Phospho-alpha-D-ribosyl)-5,6-dimethylbenzimidazole via dephosphorylation by the enzyme phosphohistidine phosphatase 1 (EC 3.1.3.-). Humans do not have all the enzymes needed to synthesize or metabolize riboflavin. However, gut microflora do have the necessary enzymatic machinery to produce and metabolize this vitamin. Riboflavin (or vitamin B2) is an easily absorbed micronutrient with a key role in maintaining health in humans and animals. It is the central component of the cofactors FAD and FMN, and is therefore required by all flavoproteins. Riboflavin is yellow or yellow-orange in color and in addition to being used as a food coloring it is also used to fortify some foods including baby foods, breakfast cereals, pastas, sauces, processed cheese, fruit drinks, vitamin-enriched milk products, some energy drinks, and vitamin supplements.

Prolyl-Tyrosine
Prolyl-Tyrosine is a dipeptide composed of proline and tyrosine. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.
Phenylalanylhydroxyproline
Phenylalanylhydroxyproline is a proteolytic breakdown product of collagen. It belongs to the family of peptides. These are compounds containing an amide derived from two or more amino carboxylic acid molecules (the same or different) by the formation of a covalent bond from the carbonyl carbon of one to the nitrogen atom of another. It is found in urine (PMID: 3782411). A dipeptide found in urine (PMID: 3782411). This is a proteolytic breakdown product of collagen. [HMDB]
Tyrosyl-Proline
Tyrosyl-Proline is a dipeptide composed of tyrosine and proline. It is an incomplete breakdown product of protein digestion or protein catabolism.
