A 78773 is a potent, selective, direct, and reversible 5-lipoxygenase inhibitor. It has activity in a variety of purified cells and in more complex biological systems such as whole blood, lung fragments, and tracheal tissues. A 78773 acts against inflamma
PF-06462894 is a morpholinopyrimidone mGlu5 (mGlu5 Ki = 6 nM) with favorable properties. PF-06462894 did not show any evidence of immune activation in a mouse drug allergy model.
Acamelin is a quinone isolated from the Australian black wood acacia melanoxylon. It is responsible for the allergy-inducing properties of the species.
Interleukin-2-inducible T cell kinase (ITK) is a non-receptor tyrosine kinase expressed in T cells, NKT cells and mast cells which plays a crucial role in regulating the T cell receptor (TCR), CD28, CD2, chemokine receptor CXCR4, and FcepsilonR-mediated signaling pathways. ITK inhibitors can be used for the treatment of inflammation and immune-mediated disorders. ITK inhibitor (N-[5-[[3-[(4-Acetylpiperazin-1-yl)carbonyl]-4-methyl-6-methoxy-phenyl]thio]thiazol-2-yl]-4-(N-1,2-dimethylpropylaminomethyl)benzamide) is the analogue of BMS-509744, which can potently and selectively inhibit Itk kinase activity. In vitro: BMS-509744 could reduce TCR-induced functions including PLCγ1 tyrosine phosphorylation, calcium mobilization, IL-2 secretion, and T-cell proliferation in vitro in both human and mouse cells [1]. In vivo: BMS-509744 suppressed the production of IL-2 induced by anti-TCR antibody administered to mice. BMS-509744 also significantly diminishes lung inflammation in a mouse model of ovalbumin-induced allergy/asthma [1]. Clinical trial: Up to now, both BMS-509744 and ITK inhibitor is still in the preclinical development stage.
AHR-5333 mandelate is an anti-allergy compound which has been shown to protect against antigen-induced anaphylactic collapse and ascaris antigen-induced skin hypersensitivity. AHR-5333 mandelate has also been shown to inhibit 5-HETE, LTB4 and LTC4 synthesis.
