生物活性 | Mirabegron is a selectiveβ3-adrenoceptoragonist withEC50of 22.4 nM. | ||||||||||||||||
IC50& Target | EC50: 22.4 nM (β3-adrenoceptor)[1] | ||||||||||||||||
体外研究 (In Vitro) | Mirabegron (YM178) increases cyclic AMP accumulation in Chinese hamster ovary (CHO) cells expressing human β3-adrenoceptor (AR). EC50value is 22.4 nM. EC50values of Mirabegron for human β1- and β2-ARs are 10,000 nM or more, respectively. EC50of Mirabegron in rat bladder strips precontracted with 10-6M Carbachol (CCh) is 5.1 μM, whereas that in human bladder strips precontracted with 10-7M CCh is 0.78 μM. Mirabegron concentration-dependently increases the accumulation of cAMP in CHO cells expressing human β3-ARs, with an EC50value and I.A. of 22.4 nM and 0.8, respectively. Mirabegron has little agonistic effect on β1- and β2-ARs. Compared by EC50value, Mirabegron is approximately one third as potent as isoproterenol. The maximal relaxant effects of Mirabegron are 94±1%, that of CCh, indicating that Mirabegron acts a full agonist in the rat bladder. The maximal relaxant effects of Mirabegron is 89.4±2.3%[1]. | ||||||||||||||||
体内研究 (In Vivo) | Mirabegron (YM178) produces a dose-dependent decrease in the frequency of rhythmic bladder contraction in anesthetized rats. In contrast, Mirabegron does not decrease the amplitude of rhythmic bladder contraction at up to 3 mg/kg i.v.. On the contrary, Oxybutynin significantly increases the frequency of rhythmic bladder contraction and decreased its amplitude at doses of 0.272 mg/kg i.v. or more[1]. | ||||||||||||||||
