Navarixin (MK-7123)(SCH527123) is a novel, selective CXC chemokine receptor 2(CXCR2) antagonist that inhibits neutrophil activation and modulates neutrophil trafficking in animal models, characteristics that may be beneficial in the treatment of conditions with unbalanced pulmonary neutrophilia.

Pentoxifylline-d6 is intended for use as an internal standard for the quantification of pentoxifylline by GC- or LC-MS. Pentoxifylline is a hemorrheologic agent. It increases the deformability of washed isolated human erythrocytes when used at a concentration of 100 µM. Pentoxifylline (1, 2, and 3 mM) inhibits ADP-induced platelet aggregation in isolated human whole blood. It inhibits thrombus formation induced by ADP in a hamster cheek pouch model when administered at doses of 5, 10, and 20 mg/kg. Formulations containing pentoxifylline have been used in the treatment of intermittent claudication.

Norfluoxetine-d5 is intended for use as an internal standard for the quantification of norfluoxetine by GC- or LC-MS. Norfluoxetine is an active metabolite of the antidepressant fluoxetine. It is formed from fluoxetine by the cytochrome P450 (CYP) isoforms CYP2C9, CYP2C19, and CYP3A. Norfluoxetine inhibits serotonin (5-HT) uptake in rat brain synaptosomal membrane preparations (Ki = 44.7 nM) and isolated human platelets (IC50 = ~15 nM). It has been found in the tissues of fish exposed to wastewater effluent.

Flufenamic acid-d4 is intended for use as an internal standard for the quantification of flufenamic acid by GC- or LC-MS. Flufenamic acid is a non-steroidal anti-inflammatory drug (NSAID) and COX inhibitor (IC50s = 3 and 9.3 µM for human COX-1 and COX-2, respectively). Flufenamic acid inhibits TNF-α-induced increases in COX-2 levels and NF-κB activation in HT-29 colon cancer cells in a concentration-dependent manner. It inhibits calcium influx induced by fMLP or A23187 in human polymorphonuclear leukocytes (PMN) with IC50 values of 29 and 14 µM, respectively. Flufenamic acid also activates various ion channels, including transient receptor potential canonical 6 (TRPC6) and the large-conductance calcium-activated potassium channel (KCa1.1). It also inhibits various ion channels, including TRPC3 and the cystic fibrosis transmembrane conductance regulator (CFTR). Flufenamic acid (20 mg/kg) reduces increases in intestinal fluid secretion and intestinal barrier disruption in mice ......

Clofibric acid-d4 is intended for use as an internal standard for the quantification of clofibric acid by GC- or LC-MS. Clofibric acid is a peroxisome proliferator-activated receptor α (PPARα) agonist (EC50 = 50 µM in a transactivation assay) and the active metabolite of clofibrate. It is formed from clofibrate by tissue and serum esterases. Dietary administration of clofibric acid (0.067-0.22%) reduces serum cholesterol, phospholipid, and triglyceride levels in rats. It decreases glutamate oxaloacetate transaminase (GOT) levels and increases glutamate pyruvate transaminase (GPT) and lactate dehydrogenase (LDH) levels, markers of xenobiotic stress, in the plasma of carp (C. carpio) when administered in tank water at a concentration of 10 µg/L. Clofibric acid has been found in wastewater effluent.

Gemfibrozil-d6 is intended for use as an internal standard for the quantification of gemfibrozil by GC- or LC-MS. Gemfibrozil is a peroxisome proliferator-activated reporter α and PPARγ agonist. In vivo, gemfibrozil reduces serum total cholesterol, triglyceride, and LDL levels in a rat model of high-cholesterol diet-induced hyperlipidemia. Gemfibrozil reduces atherosclerotic plaque area, superoxide production, and expression of the genes encoding the NF-κB subunit p65 and chemokine (C-C) motif ligand 2 (CCL2) in ApoE-/- mice. Formulations containing gemfibrozil have been used in the treatment of high cholesterol.

JNJ-40413269 is a competitive inhibitor of fatty acid amide hydrolase (FAAH), which demonstrates robust central target engagement, and shows efficacious in a rat model of neuropathic pain.

DSP-6952 is a 5-HT4 receptor partial agonist, inhibiting visceral hypersensitivity and ameliorating gastrointestinal dysfunction.

MK-886 sodium salt inhibits leukotriene biosynthesis in leukocytes.
