D018926 - Anti-Allergic Agents Oxatomide is a potent and orally active dual H1-histamine receptor and P2X7 receptor antagonist with antihistamine and anti-allergic activity. Oxatomide almost completely blocks the ATP-induced current in human P2X7 receptors (IC50 of 0.95 μM). Oxatomide inhibits ATP-induced Ca2+ influx with an IC50 value of 0.43 μM and also inhibits serotonin[1][2].

Darifenacin

2-[(3S)-1-[2-(2,3-dihydro-1-benzofuran-5-yl)ethyl]pyrrolidin-3-yl]-2,2-diphenylacetamide

C78272 - Agent Affecting Nervous System > C29698 - Antispasmodic Agent D000089162 - Genitourinary Agents > D064804 - Urological Agents Darifenacin(UK88525) is a selective M3 muscarinic receptor antagonist with pKi of 8.9. IC50 value: 8.9 (pKi) [1] Target: M3 receptor in vitro: Darifenacin exerts non-parallel rightward displacement of the agonist curve and also significant depression of the maximum response (+)-cis-Dioxolane produced concentration-dependent contraction of the isolated bladder of rat [1]. Darifenacin produces a concentration dependent increase in R123 (P-gp probe) accumulation in MDCK cells. Darifenacin stimulates ATPase activity in P-gp membrane in a clear concentration dependent response manner with an estimated ED50 value of 1.6 μM. Darifenacin (100 nM) shows a significantly greater permeability for darifenacin in the basolateral to apical direction resulting in an efflux ratio in BBMEC monolayers of approximately 2.6 [2]. in vivo: Darifenacin produces dose-dependent inhibition of amplitude of volume-induced bladder contractions(VIBCAMP), producing 35\% inhibition at dose of 283.3 nmol/kg and maximal inhibition of approximately 50–55\% [1]. Darifenacin (0.1 mg/kg i.v.) reduces bladder afferent activity in both Aδ and C fibers in female Sprague-Dawley rats, the decrease in afferent spikes in C fibers may be more pronounced than that in Aδ fibers [3].
