Inverse Agonism of SQ 29,548 and Ramatroban on Thromboxane A2 Receptor
Inverse Agonism of SQ 29,548 and Ramatroban on Thromboxane A2 Receptor Raja Chakraborty1,3, Rajinder P. Bhullar1, Shyamala Dakshinamurti2,3, John Hwa4, Prashen Chelikani1,2,3* 1 Department of Oral Biology, University of Manitoba, Winnipeg, Manitoba, Canada, 2 Departments of Pediatrics, Physiology, University of Manitoba, Winnipeg, Manitoba, Canada, 3 Biology of Breathing Group- Manitoba Institute of Child Health, Winnipeg, Manitoba, Canada, 4 Department of Internal Medicine (Cardiology), Cardiovascular Research Center, Yale University School of Medicine, New Haven, Connecticut, United States of America Abstract G protein-coupled receptors (GPCRs) show some level of basal activity even in the absence of an agonist, a phenomenon referred to as constitutive activity. Such constitutive activity in GPCRs is known to have important pathophysiological roles in human disease. The thromboxane A2 receptor (TP) is a GPCR that promotes thrombosis in response to binding of the prostanoid, thromboxane A2. TP dysfunction is widely implicated in pathophysiological conditions such as bleeding disorders, hypertension and cardiovascular disease. Recently, we reported the characterization of a few constitutively active mutants (CAMs) in TP, including a genetic variant A160T. Using these CAMs as reporters, we now test the inverse agonist properties of known antagonists of TP, SQ 29,548, Ramatroban, L-670596 and Diclofenac, in HEK293T cells. Interestingly, SQ 29,548 reduced the basal activity of both, WT-TP and the CAMs while Ramatroban was able to reduce the basal activity of only the CAMs. Diclofenac and L-670596 showed no statistically significant reduction in basal activity of WT-TP or CAMs. To investigate the role of these compounds on human platelet function, we tested their effects on human megakaryocyte based system for platelet activation. -

Batch specific analytical results are provided on each certificate of analysis. Laboratory Procedures CAY10471 is supplied as a crystalline solid. CAY10471 is supplied as a crystalline solid. A stock solution may be made by dissolving the CAY10471 in an organic solvent purged with an inert gas. CAY10471 is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide (DMF). The solubility of CAY10471 in these solvents is approximately 15 mg/ml in ethanol and approximately 30 mg/ml in DMSO and DMF. CAY10471 is sparingly soluble in aqueous buffers. For maximum solubility in aqueous buffers, CAY10471 should first be dissolved in DMSO and then diluted with the aqueous buffer of choice. CAY10471 has a solubility of approximately 0.5 mg/ml in a 1:5 solution of DMSO:PBS (pH 7.2) using this method. We do not recommend storing the aqueous solution for more than one day. Description The biological effects of PGD2 are transduced by at least two 7-transmembrane G-protein coupled receptors, designated DP1 and CRTH2/DP2. BAY-u3405 (Ramatroban) is an approved human medication for the treatment of allergic rhinitis that has documented activity as an antagonist of 1,2 both the TP and CRTH2/DP2 receptors. -
