Lower urinary tract symptoms (LUTS) are present in many common urological syndromes. However, their current suboptimal management by muscarinic and alpha(1)-adrenoceptor antagonists leaves a significant opportunity for the discovery and development of superior medicines. As potential targets for such therapeutics, purinoceptors have emerged over the last(More)
P2X(3) and P2X(2/3) receptors are localized on sensory afferents both peripherally and centrally and have been implicated in various sensory functions. However, the physiological role of these receptors expressed presynaptically in the spinal cord in regulating sensory transmission remains to be elucidated. Here, a novel selective P2X(3) and P2X(2/3)(More)
PURPOSE We investigated the pharmacological effect of TRPV1 antagonists in anesthetized rodent models of bladder function. MATERIALS AND METHODS The TRPV1 antagonists JNJ17203212 and JYL1421 were evaluated in the anesthetized rat volume induced micturition reflex model. JNJ17203212 was further evaluated in this model in capsaicin (Sigma) desensitized(More)
PURPOSE We investigated the role of prostacyclin on afferent modulation of the micturition reflex using the novel selective prostacyclin receptor antagonist RO3244019 in rat models of bladder function. MATERIALS AND METHODS The effects of RO3244019 on urodynamic parameters were evaluated in 3 rat models. In the anesthetized isovolumetric bladder(More)
