Adriforant tartrate hydrate, also known as ZPL-3893787 tartrate hydrate, PF-3893787 tartrate hydrate and ZPL-389 tartrate hydrate, is a novel histamine H4 receptor antagonist. Adriforant tartrate hydrate shows an excellent in vitro profile that warrants their further investigation in relevant models of human disease. Histamine H4 receptor (H4R) has become a promising target for immuno-inflammatory diseases, such as allergic rhinitis, asthma or dermal allergies.

Clemizole sulfate is a drug in clinical development for the treatment of hepatitis C virus (HCV) infection. Clemizole is a novel inhibitor of TRPC5 channels. Clemizole is an H1 antagonist. Clemizole, an antihistamine drug that was once widely used for treatment of allergic disease, was recently discovered to be a potent inhibitor (IC50, 24 nM) of the interaction between an HCV protein (NS4B) and HCV RNA. Although clemizole was widely used during the 1950s and 1960s, this was before contemporary regulatory requirements were established for new drug development, and there is very minimal information about its pharmacokinetics and metabolism.

PM-43I is a potent inhibitor of both STAT5- and STAT6-dependent allergic airway disease in mice.

Theophylline-d6 is intended for use as an internal standard for the quantification of theophylline by GC- or LC-MS. Theophylline is an inhibitor of phosphodiesterase. It is also an adenosine A1 and A2 receptor antagonist. Theophylline induces relaxation of isolated cat bronchial smooth muscle segments precontracted with acetylcholine. It inhibits ovalbumin-induced increases in bronchoalveolar lavage fluid (BALF) eosinophil infiltration in an ovalbumin-sensitized mouse model of allergic asthma. Formulations containing theophylline have been used in the treatment of asthma and chronic obstructive pulmonary disease (COPD).

(±)9(10)-DiHOME, the diol derivative of (±)9(10)-EpOME—a cytochrome P450-derived epoxide of linoleic acid also known as leukotoxin—is formed through the action of soluble epoxide hydrolase (sEH) in neutrophils. It exhibits toxicity towards Sf21 cells expressing sEH as well as tolacZ-expressing control cells, differing from leukotoxin which only harms sEH-containing cells. Furthermore, combined exposure to 9(10)- and 12(13)-DiHOME leads to cell death in rabbit renal proximal tubule cells by disrupting mitochondrial respiration, and causes lung injury, respiratory distress, and mortality in mice, highlighting its role as a toxic lipid mediator. Specifically, 9(10)-DiHOME has been associated with acute respiratory distress syndrome (ARDS), a severe and often deadly complication in patients with major burns. Elevated levels of this compound have been detected in the bronchoalveolar lavage fluid (BALF) of women, but not men, with chronic obstructive pulmonary disease (COPD), and its levels are also increased in patients with allergic asthma, indicating its significance in respiratory conditions.
