Application

TIQ-A has been used as a PAPR-1 inhibitor to study eosinophilic infiltration into the airways of OVA-challenged mice¹. It has also been used to study its role in the regression of atherosclerotic plaques in high-fat diet-fed ApoE(-/-) mice².

Biochem/physiol Actions

TIQ-A is a potent inhibitor of PARP, anti-apoptotic.

Preparation Note

TIQ-A is soluble in DMSO at 16 mg/ml.

Thieno[2,3-c]isoquinolin-5-one, a potent poly(ADP-ribose) polymerase inhibitor, promotes atherosclerotic plaque regression in high-fat diet-fed apolipoprotein E-deficient mice: effects on inflammatory markers and lipid content.

Chetan P Hans et al.

The Journal of pharmacology and experimental therapeutics, 329(1), 150-158 (2009-01-07)

We recently showed that poly(ADP-ribose) polymerase (PARP) is activated within atherosclerotic plaques in an animal model of atherosclerosis. Pharmacological inhibition of PARP or reduced expression in heterozygous animals interferes with atherogenesis and may promote factors of plaque stability, possibly reflecting

Poly(ADP-ribose) polymerase-1 inhibition prevents eosinophil recruitment by modulating Th2 cytokines in a murine model of allergic airway inflammation: a potential specific effect on IL-5.

Mustapha Oumouna et al.

Journal of immunology (Baltimore, Md. : 1950), 177(9), 6489-6496 (2006-10-24)

We recently used a murine model of allergic airway inflammation to show that poly(ADP-ribose) polymerase-1 (PARP-1) plays an important role in the pathogenesis of asthma-related lung inflammation. In this study, we show that PARP-1 inhibition, by a novel inhibitor (TIQ-A)
