Oliceridine (TRV130) is an opioid drug that is under evaluation in human clinical trials for the treatment of acute severe pain. It is afunctionally selective μ-opioid receptor agonist developed by Trevena Inc. Oliceridine elicits robust G protein signaling, with potencyand efficacy similar to morphine, but with far less β-arrestin 2 recruitment and receptor internalization, it displays less adverse effectsthan morphine.^[1][2][3]

In 2015, the product was granted fast track designation in the U.S. for the treatment of moderate to severe acute pain. In 2016, the compound was granted FDA breakthrough therapy designation for the management of moderate to severe acute pain.

Structure–Activity Relationships and Discovery of a G Protein Biased μ Opioid Receptor Ligand, [(3-Methoxythiophen-2-yl)methyl]({2-[(9R)-9-(pyridin-2-yl)-6-oxaspiro-[4.5]decan-9-yl]ethyl})amine (TRV130), for the Treatment of Acute Severe Pain

Abstract

The concept of “ligand bias” at G protein coupled receptors has been introduced to describe ligands which preferentially stimulate one intracellular signaling pathway over another. There is growing interest in developing biased G protein coupled receptor ligands to yield safer, better tolerated, and more efficacious drugs. The classical μ opioid morphine elicited increased efficacy and duration of analgesic response with reduced side effects in β-arrestin-2 knockout mice compared to wild-type mice, suggesting that G protein biased μ opioid receptor agonists would be more efficacious with reduced adverse events. Here we describe our efforts to identify a potent, selective, and G protein biased μ opioid receptor agonist, TRV130 ((R)-30). This novel molecule demonstrated an improved therapeutic index (analgesia vs adverse effects) in rodent models and characteristics appropriate for clinical development. It is currently being evaluated in human clinical trials for the treatment of acute severe pain.

[(3-Methoxythiophen-2-yl)methyl]({2-[(9R)-9-(pyridin-2-yl)-6-oxaspiro[4.5]decan-9- yl]ethyl})amine

Into a vial were added 2-[(9R)-9-(Pyridin-2-yl)-6-oxaspiro[4.5]decan-9-yl]ethan-l -amine (500 mg, 1.92 mmole), 18 mL CH2C12 and sodium sulfate (1.3 g, 9.6 mmole). The 3- methoxythiophene-2-carboxaldehyde (354 mg, 2.4 mmole) was then added, and the misture was stirred overnight. NaBH4 (94 mg, 2.4 mmole) was added to the reaction mixture, stirred for 10 minutes, and then MeOH (6.0 mL) was added, stirred l h, and finally quenched with water. The organics were separated off and evaporated. The crude residue was purified by a Gilson prep HPLC. The desired fractions collected and concentrated and lyophilized. After lyophilization, residue was partitioned between CH2C12 and 2N NaOH, and the organic layers were collected. After solvent was concentrated to half of the volume, 1.0 eq of IN HC1 in Et20 was added,and majority of solvent evaporated under reduced pressure. The solid obtained was washed several times with Et20 and dried to provide [(3-methoxythiophen-2-yl)methyl]({2-[(9R)-9-(pyridin-2- yl)-6-oxaspiro[4.5]decan-9-yl]ethyl})amine monohydrochloride (336 mg, 41% yield, m/z 387.0 [M + H]+ observed) as a white solid. The NMR for Compound 140 is described herein.

After 3h, TLC (25%EtOAc in hexane, PMA stain) showed the reaction was completed. After cooling, benzene (50 ml) was added and the layer was separated, the organic was washed by water (120 ml) and the aqueous layer was extracted by CH2CI2 (3 x 120 ml). The combined organic was washed with sat’d NaHCCb, brine, dried and concentrated and the residual was purified by flash chromatography (340 g silica gel column, eluted by EtOAc in hexane: 5% EtOAc, 2CV; 5-25%, 14CV; 25-40%,8 CV) gave a mixture of E and Z isomers: methyl 2-cyano-2-[6- oxaspiro[4.5]decan-9-ylidene]acetate ( 18.37 g, 87.8 % yield, m/z 236.0 [M + H]⁺ observed) as a clear oil. -cyano-2-[9-(pyridin-2-yl)-6-oxaspiro[4.5]decan-9-yl]acetate

Ethylene glycol (300 ml) was added to methyl 2-cyano-2-[9-(pyridin-2-yl)-6- oxaspiro[4.5]decan-9-yl]acetate( 15.43 g, 49 mmol) followed by potassium hydroxide (5.5 g , 98 mmol), the resulting mix was heated to 120oC, after 3 h, the reaction mix was cooled and water (300 ml) was added, the product was extracted by Et20(3 x 400 ml), washed with water(200 ml), dried (Na2S04) and concentrated, the residual was purified by flash chromatography (340 g silica gel column, eluted by EtOAc in hexane: 3% 2CV; 3-25%, 12 CV; 25-40% 6CV to give 2-[9-(Pyridin-2-yl)-6-oxaspiro[4.5]decan-9- yl]acetonitrile (10.37 g, 82% yield, m/z 257.0 [M + H]+ observed).

-yl)-6-oxaspiro[4.5]decan-9-yl]acetonitrile

racemic 2-[9-(pyridin-2-yl)-6-oxaspiro[4.5]decan-9-yl]acetonitrile was separated by chiral HPLC column under the following preparative-SFC conditions: Instrument: SFC-80 (Thar, Waters); Column: Chiralpak AD-H (Daicel); column temperature: 40 °C; Mobile phase: Methanol /CO2=40/60; Flow: 70 g/min; Back pressure: 120 Bar; Cycle time of stack injection: 6.0min; Load per injection: 225 mg; Under these conditions, 2-[9-(pyridin-2-yl)-6-oxaspiro[4.5]decan-9-yl]acetonitrile (4.0 g) was separated to provide the desired isomer, 2-[(9R)-9-(Pyridin-2-yI)-6- oxaspiro[4.5]decan-9-yl]acetonitrile (2.0 g, >99.5% enantiomeric excess) as a slow- moving fraction.

[0240] -[(9R)-9-(Pyridin-2-yl)-6-oxaspiro[4.5]decan-9-yl]ethan-l-amine

LAH (1M in Et20, 20ml, 20 mmol) was added to a solution of 2-[(9R)-9-(pyridin-2-yl)- 6-oxaspiro[4.5]decan-9-yl]acetonitrile (2.56 g, 10 mmol) in Et20 (100 ml, 0.1M ) at OoC under N₂. The resulting mix was stirred and allowed to warm to room temperature. After 2 h, LCMS showed the reaction had completed. The reaction was cooled at OoC and quenched with water ( 1.12 ml), NaOH (10%, 2.24 ml) and another 3.36 ml of water. Solid was filtered and filter pad was washed with ether (3 x 20 ml). The combined organic was dried and concentrated to give 2-[(9R)-9-(Pyridin-2-yl)-6- oxaspiro[4.5]decan-9-yl]ethan-l -amine (2.44 g, 94% yield, m/z 260.6 [M + H]+ observed) as a light amber oil.

Alternatively, 2-[(9R)-9-(Pyridin-2-yl)-6-oxaspiro[4.5]decan-9-yl]ethan-l -amine was prepared by Raney-Nickel catalyzed hydrogenation.

An autoclave vessel was charged with 2-[(9R)-9-(pyridin-2-yl)-6-oxaspiro[4,5]decan-9- yl] acetonitrile and ammonia (7N solution in methanol). The resulting solution was stirred at ambient conditions for 15 minutes and treated with Raney 2800 Nickel, slurried in water. The vessel was pressurized to 30 psi with nitrogen and agitated briefly. The autoclave was vented and the nitrogen purge repeated additional two times. The vessel was pressurized to 30 psi with hydrogen and agitated briefly. The vessel was vented and purged with hydrogen two additional times. The vessel was pressurized to 85-90 psi with hydrogen and the mixture was warmed to 25-35 °C. The internal temperature was increased to 45-50 °C over 30-60 minutes. The reaction mixture was stirred at 45-50 °C for 3 days. The reaction was monitored by HPLC. Once reaction was deemed complete, it was cooled to ambient temperature and filtered through celite. The filter cake was washed with methanol (2 x). The combined filtrates were concentrated under reduced pressure at 40-45 °C. The resulting residue was co-evaporated with EtOH (3 x) and dried to a thick syrupy of 2-[(9R)-9-(pyridin-2-yl)-6-oxaspiro[4.5]decan-9-yl]ethan-l -amine.
