orexin type 2 receptor agonist, TAK-861, TAK 861, 59MF6P2ATF

Oveporexton is a small molecule drug. The usage of the INN stem ‘-orexton’ in the name indicates that Oveporexton is a orexin receptor agonist. Oveporexton has a monoisotopic molecular weight of 520.15 Da.

Oveporexton (INNTooltip International Nonproprietary Name; developmental code name TAK-861) is an orexin receptor agonist and wakefulness-promoting agent which is under development for the treatment of narcolepsy (types 1 and 2) and idiopathic hypersomnia.[1][2][3] It is taken by mouth.[1][2]

The drug acts as a selective agonist of the orexin OX2 receptor.[1][2] It has wakefulness-promoting effects in animals, including in rodents and monkeys.[2] In addition, oveporexton has been found to be effective in the treatment of narcolepsy and cataplexy in phase 3 clinical trials in humans.[4][5][6] The drug is a first-in-class medication and targets the root symptomatic cause of narcolepsy (type 1) by remediating the orexin (hypocretin) deficiency that is present in the condition.[7][8][9]

Oveporexton is being developed by Takeda.[1] As of July 2025, it has completed phase 3 clinical trials for treatment of narcolepsy, whereas no recent development has been reported for treatment of idiopathic hypersomnia.[1][5][10] Takeda plans to submit a New Drug Application (NDA) of oveporexton for the treatment of narcolepsy to the United States Food and Drug Administration (FDA) in 2025.[5] Oveporexton is a follow-on and replacement compound for Takeda’s earlier lead drug danavorexton (TAK-925), which is administered intravenously and stopped being developed due to unexpected liver toxicity findings.[10]

Example 3

N-{(2S,3R)-4,4-difluoro-1-(2-hydroxy-2-methylpropanoyl)-2-. [(2,3′,5′-trifluoro[1,1′-biphenyl]-3-yl)methyl]pyrrolidin-3-yl}ethanesulfonamide

A) tert-butyl (2S,3R)-3-(ethylsulfonamido)-4,4-difluoro-2-((2,3′,5′-trifluoro-[1,1′-biphenyl]-3-yl)methyl)pyrrolidine-1-carboxylate

      To a mixture of tert-butyl (2S,3R)-2-(3-chloro-2-fluorobenzyl)-3-(ethylsulfonamido)-4,4-difluoropyrrolidine-1-carboxylate (3.70 g), (3,5-difluorophenyl)boronic acid (2.56 g) and 1 M aqueous potassium phosphate solution (24.3 mL) in DME (50 mL) was added XPhos Pd G3 (0.343 g) at room temperature. The mixture was stirred at 90° C. under nitrogen atmosphere for 15 h. The reaction mixture was poured into water and extracted with EtOAc. The organic layer was washed with saturated brine, dried over magnesium sulfate and concentrated under reduced pressure. The residue was purified by column chromatography (silica gel, EOAc/hexane) to give the title compound (3.30 g).
      MS: [M−H] − 533.2.

B) N-((2S,3R)-4,4-difluoro-2-((2,3′,5′-trifluoro-[1,1′-biphenyl]-3-yl)methyl)pyrrolidin-3-yl)ethanesulfonamide hydrochloride

      A mixture of tert-butyl (2S,3R)-3-(ethylsulfonamido)-4,4-difluoro-2-((2,3′,5′-trifluoro-[1,1′-biphenyl]-3-yl)methyl)pyrrolidine-1-carboxylate (3.30 g) and 4 M HCl/CPME solution (30 mL) was stirred overnight at room temperature. By filtration, the title compound (2.86 g) was obtained.
      MS: [M+H] + 435.1.

C) N-{(2S,3R)-4,4-difluoro-1-(2-hydroxy-2-methylpropanoyl)-2-[(2,3′,5′-trifluoro[1,1′-biphenyl]-3-yl)methyl]pyrrolidin-3-yl}ethanesulfonamide

      To a mixture of N-((2S,3R)-4,4-difluoro-2-((2,3′,5′-trifluoro-[1,1′-biphenyl]-3-yl)methyl)pyrrolidin-3-yl)ethanesulfonamide hydrochloride (200 mg) and DIPEA (0.367 ml) in THF (3 mL) was added alpha-acetoxy-isobutyryl chloride (0.074 ml) at 0° C., and the mixture was stirred at same temperature for 10 min. To the mixture were added water (1 ml) and 4 M lithium hydroxide solution (1.06 ml), and the mixture was stirred overnight at room temperature. The mixture was diluted with saturated brine and extracted with EtOAc. The extract was dried over magnesium sulfate and concentrated under reduced pressure. The residue was purified by column chromatography (silica gel, EtOAc/hexane) and recrystallized from EtOAc/hexane to give the title compound (154 mg).
       1H NMR (400 MHz, CDCl 3) δ 1.32-1.40 (9H, m), 2.27-2.54 (1H, m), 2.88-3.16 (4H, m), 4.02-4.49 (3H, m), 4.86-5.20 (2H, m), 6.78-6.86 (1H, m), 7.02-7.10 (2H, m), 7.16-7.22 (1H, m), 7.27-7.31 (1H, m), 7.35-7.43 (1H, m).
