| Background | It is a long-acting beta-adrenergic receptor agonist. |
| Biological Activity | Indacaterol Maleate 是一种长效的β-肾上腺素受体激动剂，对β1-adrenoceptor的pKi为 7.36，对 β2-adrenoceptor 的pKi为5.48，可以用于治疗哮喘和慢性阻塞性肺病。[1] |
| In Vitro | Indacaterol is close to a full agonist at the human beta(2)adrenoceptor(E(max)= 73 +/- 1% of the maximal effect of isoprenaline; pEC(50)= 8.06 +/- 0.02).[1] Indacaterol as a fast acting compound with a longer duration of action than salmeterol and formoterol.[2] Duration of action was determined against cholinergic neural contraction induced by electrical field stimulation(EFS). At resting tone，-logEC50 and Emax values were 8.82+/-0.41 and 77+/-5% for indacaterol. Indacaterol's onset of action(7.8+/-0.7 min) was significantly faster than that of salmeterol(19.4+/-4.3 min). EFS-induced contractions were inhibited with -logIC50 values of 6.96+/-0.13(indacaterol). Duration of action was >12 h for indacaterol and salmeterol.[3] Indacaterol is an effective inhibitor of the release of mediators from human lung mast cells. Indacaterol was as potent and as efficacious as the full agonist，isoprenaline(EC(50)，approximately 4 nmol x L(-1))，at inhibiting the IgE-dependent release of histamine from mast cells.[4] In both the low- and high-expression recombinant GEVT 'wild type' cell lines indacaterol is a high-efficacy agonist. In the human primary ASM cells indacaterol gave a maximal response intermediate between that of salmeterol and formoterol.[5] |
| In Vivo | In isolated superfused guinea pig trachea，indacaterol has a fast onset of action(30 +/- 4 min)and a long duration of action(529 +/- 99 min). In the conscious guinea pig，when given intratracheally as a dry powder，indacaterol inhibits 5-hydroxytryptamine-induced bronchoconstriction for at least 24 h，whereas salmeterol，formoterol，and salbutamol have durations of action of 12，4，and 2 h，respectively.[1] |
