JNJ-54717793 is an orally active, brain-penetrating compound that acts as a selective and high-affinity antagonist of the orexin-1 receptor (OX1R) with a plasma EC50 of 85 ng/mL. It demonstrates K_i values of 16 nM for hOX1R (human OX1R) and 700 nM for hOX2R, indicating its strong preference for hOX1R over hOX2R. JNJ-54717793 is recognized for its effectiveness in the treatment of anxiety disorders.

3,5-Dihydroxybenzoic acid is a metabolite of alkylresorcinols in human urine and plasma, a potential biomarker of food intake such as beer, nuts, peanuts, and legumes, and a selective hydroxycarboxylic acid 1 (HCA1) inhibitor.

Apixaban (BMS-562247-01) is an orally active anticoagulant that inhibits coagulation factor Xa, directly preventing the conversion of prothrombin to thrombin and the formation of cross-linked fibrin clots.

Pyrocatechuic acid (Catecholcarboxylic acid), a normal human benzoic acid metabolite found in plasma, has increased levels after aspirin ingestion.

Pipecolic acid (2-Piperidinecarboxylic acid), a metabolite of lysine found in human physiological fluids such as urine, plasma and CSF, is an important regulator of immunity in plants and humans alike.

L-Allothreonine (L-allo-Threonine) is an essential amino acid in humans. L-Allothreonine is abundant in human plasma, particularly in newborns. Severe deficiency of threonine causes neurological dysfunction and lameness in experimental animals. L-Allothreonine is an immunostimulant which promotes the growth of thymus gland. L-Allothreonine also can probably promote cell immune defense function. L-Allothreonine is highly concentrated in meat products, cottage cheese, and wheat germ.

Cholesteryl sulfate sodium (Sodium Cholesteryl Sulfate) is a sterol sulfate in human plasma. Cholesteryl sulfate sodium is a component of cell membrane and has a regulatory function. Cholesteryl sulfate sodium also activates multiple protein kinase C (PKC) iso-enzymes, especially the ε, η and ζ isoforms.

3-Chloro-L-Tyrosine (Chlorotyrosine), a specific marker of myeloperoxidase-catalyzed oxidation, is markedly elevated in low-density lipoprotein isolated from human atherosclerotic intima. In particular, myeloperoxidase halogenates tyrosine residues in plasma proteins and generates 3-chlorotyrosine (CY). The detection of free chlorotyrosine in blood or urine arises from the degradation of these chlorinated proteins. CY concentrations may be useful for monitoring the activation of neutrophils in asthmatic patients.

1-Hydroxyoctadecane (OctadecanolOctadecanol) is a fatty alcohol present in human and is normally incorporated into plasmalogen lipids. Sjogren-Larsson syndrome is defined by the triad of ichthyosis, mental retardation, and spasticity, and patients accumulate fatty alcohols such as Octadenol in the plasma and cultured fibroblasts.

(R)-pyrrolidine-2-carboxylic acid (D-Proline) is an isomer of the naturally occurring amino acid L-Proline. D-amino acids, including D-Proline, are found in relatively high abundance in human plasma and saliva, potentially originating from bacterial sources or endogenous production via amino acid racemase activity.

Isethionic acid sodium salt (Sodium isethionate) is an organosulfur compound containing a short chain alkane sulfonate linked to a hydroxyl group. Mammals are able to endogenously synthesize Isethionic acid sodium salt via taurine through a possible enzymatic deamination process. Isethionic acid sodium salt can be found in both human plasma and urine. Higher plasma levels of Isethionic acid sodium salt have been shown to be protective against type 2 diabetes.

N-Acetyl-L-arginine (Ac-Arg-OH), an N-acyl-L-alpha-amino acid with a strong basic nature (based on its pKa), has elevated serum levels in hyperargininemic patients and is associated with several diseases, including uremia and colorectal cancer. In untreated hyperargininemic patients, it reaches its highest levels in cerebrospinal fluid. It has also been detected in apples and loquats, suggesting it could be a potential biomarker for consumption of these foods. Additionally, a low-arginine diet combined with sodium benzoate therapy leads to a marked decrease in plasma N-acetyl-L-arginine concentrations.
