| Use | Odarterol has a nearly full-effect β2-receptor agonism (the semi-maximum effect concentration is 0.1nM, and the affinity internal activity with isoprenaline is 88%). Otarterol has different effects on different β-adrenergic receptors. It has a complete agonist effect on β2-receptors, while it is a partial agonist to β1-adrenergic receptors. |

BI 1744(Olodaterol - Introduction
Odarterol (Olodaterol) is a new type of selective fast-acting β2-adrenergic receptor agonist. This product can bind to β2 receptors to increase the level of intracellular cAMP, which in turn causes protein kinase A The activation and phosphorylation of other related targets finally achieve the effect of dilating the trachea. Odarol has high selectivity for β2-adrenergic receptors (referred to as β2-receptors) and has rapid onset of effect, long half-life, more than 12h, can maintain 24h of bronchodilation.

BI 1744(Olodaterol - Synthesis method
Synthesis method of odaterol:
- 2, 5-dihydroxyacetophenone (
- Reaction with benzyl bromide to obtain 1-[2-hydroxy-5-(benzyloxy)-phenyl] ethanone
- After nitration, it is reduced to 1-[2-hydroxy-3-amino-5-(benzyloxy) phenyl]-ethanone under the action of platinum dioxide
- 6-benzyloxy-8-(2-bromoacetyl)-2H-benzo [B][1,4]-oxazine -3(4H)-one is obtained by acyl chlorination reaction, intramolecular condensation and bromination reaction
- (R)-6-benzyloxy-8-(ethylene oxide -2-yl)-2H-benzo [B][1,4] oxazine -3(4H)-one obtained by asymmetric reduction and intramolecular ring
- Condensation with 1-(4-methoxyphenyl)-2-methyl-2-propylamine (9) to obtain 6-benzyloxy-8-[(1R)-1-hydroxy-2-[[2-(4-methoxyphenyl)-1, 1-dimethylethyl] amino] ethyl]-2H-benzo [B][1,4] oxazine -3(4H)-one
- re-debenzyl protection 1, the total yield 16.2% (in 2).
platinum dioxide used in this method is more expensive, and the bromination reaction yield is low (74%). Compound 2 is protected by benzylation, nitration, nitro reduction, acyl chlorination, intramolecular condensation, oxidation, esterification, condensation and debenzyl. The target product obtained by this method is the racemate of Odarterol, which is not a single configuration target product.
