BI-1744-CL (hydrochloride) marketed as drug
Olodaterol hydrochloride [usan]
Striverdi (olodaterol) is the second molecule to be licenced for delivery via the company’s Respimat Soft Mist inhaler, following the COPD blockbuster Spiriva (tiotropium). The drug was approved in Europe in November based on results from a Phase III programme that included more than 3,000 patients with moderate to very severe disease.http://www.pharmatimes.com/Article/14-07-01/BI_launches_COPD_drug_Striverdi_in_UK_and_Ireland.aspx

Also known as the trade name Striverdi Respimat, Olodaterol is efficacious as a long-acting beta-agonist, which patients self-administer via an easy to use metered dose inhaler. While early statistics from clinical trials of Olodaterol were encouraging, a new set of data was released earlier this week, which only further solidified the effectual and tolerable benefits of this COPD drug.
On September 10, 2013 results from two Phase 3 studies of Olodaterol revealed additional positive results from this formidable COPD treatment. The conclusion from these two 48 week studies, which included over 3,000 patients, showed sizable and significant improvements in the lung function of patients who were dosed with Olodaterol. Patients in the aforementioned studies were administered either a once a day dosage of Olodaterol via the appropriate metered-dose inhaler or “usual care”. The “usual care” included a variety of treatment options, such as inhaled corticosteroids (not Olodaterol), short and long acting anticholinergics, xanthines and beta agonists, which were short acting. The clinical trial participants who were dosed with Olodaterol displayed a rapid onset of action from this drug, oftentimes within the first five minutes after taking this medication. Additionally, patients dispensed the Olodaterol inhaler were successfully able to maintain optimum lung function for longer than a full 24 hour period. The participants who were given Olodaterol experienced such an obvious clinical improvement in their COPD symptoms, and it quickly became apparent that the “usual care” protocol was lacking in efficacy and reliability.
A staggering 24 million patients in the United States suffer from chronic obstructive pulmonary disease, and this patient population is in need of an effectual, safe and tolerable solution. Olodaterol is shaping up to be that much needed solution. Not only have the results from studies of Olodaterol been encouraging, the studies themselves have actually been forward thinking and wellness centered. Boehringer Ingelheim is the first company to included studies to evaluate exercise tolerance in patients with COPD, and compare the data to those patients who were dosed with Olodaterol. By including exercise tolerance as an important benchmark in pertinent data for Olodaterol, Boehringer Ingelheim has created a standard for COPD treatment expectations. The impaired lung function for patients with COPD contributes greatly to their inability to exercise and stay healthy. Patients who find treatments and management techniques to combat the lung hyperinflation that develops during exercise have a distinct advantage to attaining overall good health.

Mechanism of action
- To a solution of 3.6 g 1,1-dimethyl-2-(4-methoxyphenyl)-ethylamine in 100 mL of ethanol at 70 ° C. 7.5 g of (6-benzyloxy-4H-benzo [1,4] oxazin-3-one )-glyoxal added and allowed to stir for 15 minutes. Then within 30 minutes at 10 to 20 ° C. 1 g of sodium borohydride added. It is stirred for one hour, with 10 mL of acetone and stirred for another 30 minutes. The reaction mixture is diluted with 150 mL ethyl acetate, washed with water, dried with sodium sulfate and concentrated. The residue is dissolved in 50 mL of methanol and 100 mL ethyl acetate and acidified with conc. Hydrochloric acid. After addition of 100 mL of diethyl ether, the product precipitates. The crystals are filtered, washed and recrystallized from 50 mL of ethanol. Yield: 7 g (68%; hydrochloride), mp = 232-234 ° C.
- 6.8 g of the above obtained benzyl compound in 125 mL of methanol with the addition of 1 g of palladium on carbon (5%) was hydrogenated at room temperature and normal pressure. The catalyst is filtered and the filtrate was freed from solvent. Recrystallization of the residue in 50 mL of acetone and a little water, a solid is obtained, which is filtered and washed.
Yield: 5.0 g (89%; hydrochloride), mp = 155-160 ° C.
- The (R) - and (S)-enantiomers of Example 3 can be obtained from the racemate, for example, by chiral HPLC (for example, column: Chirobiotic T, 250 x 1.22 mm from the company Astec). As the mobile phase, methanol with 0.05% triethylamine and 0.05% acetic acid. Silica gel with a grain size of 5 microns, to which is covalently bound the glycoprotein teicoplanin can reach as column material used. Retention time (R enantiomer) = 40.1 min, retention time (S-enantiomer) = 45.9 min. The two enantiomers can be obtained by this method in the form of free bases. According to the invention of paramount importance is the R enantiomer of Example 3
