[0002] The present invention relates to substituted pyrrolidinyl and piperidinyl compounds, particularly substituted pyrrolidinyl and piperidinyl compounds having agonist activity.

Background Art

[0003] Orexin is a neuropeptide synthesized and released by a subpopulation of neurons in the lateral hypothalamus and surrounding regions. It consists of two subtypes: orexin A and orexin B. Orexin A and orexin B bind to orexin receptors. Orexin receptors are G protein-coupled receptors that are preferentially expressed in the brain. There are two subtypes (type 1 and type 2) of orexin receptors (Cell, Vol. 92, 573-585, 1998). Activation of orexin receptors is known to be important for various central nervous system functions such as maintenance of wakefulness, energy homeostasis, reward processing, and motivation (Saper et al., TRENDS in Neuroscience 2001; Yamanaka et al., Neuron 2003; Sakurai, Nature Reviews Neuroscience 2014).

[0004] Narcolepsy is a neurological disorder that causes excessive daytime sleepiness, sudden episodes of muscle paralysis (cataplexy), and disrupted sleep patterns (Mahoney et al., Nature Reviews Neuroscience, 2019). Narcolepsy is known to be caused by the degeneration of orexin neurons. Narcolepsy symptoms can be modeled in transgenic mice engineered to degenerate orexin neurons, and those symptoms can be reversed by intracerebroventricular administration of orexin peptides (Proc. Natl. Acad. Sci. USA, Vol. 101, 4649-4654, 2004). Studies of orexin-2 receptor knockout mice suggest that the orexin-2 receptor plays a preferential role in maintaining the awake state (Cell, Vol. 98, 437-451, 1999, Neuron, Vol. 38, 715-730, 2003). Thus, orexin-2 receptor agonists may be therapeutic agents for narcolepsy or other disorders presenting excessive daytime sleepiness, such as Parkinson's disease (CNS Drugs, Vol. 27, 83-90, 2013; Brain, Vol. 130, 2007, 1586-1595).

[0005] Compounds having agonist activity for orexin-2 receptor are considered to be useful as novel therapeutic agents for narcolepsy, idiopathic hypersomnia, hypersomnia, sleep apnea syndrome, disorders of consciousness such as lethargy, narcolepsy syndrome, hypersomnia syndrome characterized by hypersomnia (for example, in Parkinson's disease, Guillain-Barré syndrome or Kleine-Levin syndrome), Alzheimer's disease, obesity, insulin resistance syndrome, heart failure, diseases related to bone loss, or sepsis, etc. (Cell Metabolism, Vol.9, 64-76, 2009; Neuroscience, Vol.121, 855-863, 2003; Respiration, Vol.71, 575-579, 2004; Peptides, Vol.23, 1683-1688, 2002; International Publication No. 2015 / 073707; Journal of the American College of Cardiology, Vol.66, 2015, pages 2522-2533; International Publication No. 2015 / 048091; International Publication No. 2015 / 147240).

[0006] Some compounds having orexin-2 receptor agonist activity have been reported (U.S. Patent No. 8,258,163; International Publication No. 2015 / 088000; International Publication No. 2014 / 198880; Journal of Medicinal Chemistry, Vol.58, pages 7931-7937; U.S. Patent Application Publication No. 20190040010; U.S. Patent Application Publication No. 20190031611; U.S. Patent Application Publication No. 20170226137). However, these compounds are considered not to be satisfactory in terms of activity, pharmacokinetics, permeability to the brain / central nervous system or safety, etc., and the development of improved compounds having orexin-2 receptor agonist activity is desired.

[0306] Example 2: Human OX2R IP1 Assay T-Rex CHO cells that stably overexpress human orexin 2 receptor (OX2R) are induced overnight using 1 μg / mL doxycycline in a T225 flask. 24 hours after induction, the cells are lifted with Accutase and plated at 30,000 cells / well in a 384-well ProxiPlate. The cells are then treated with different test compounds for 1 hour at 37 °C in 1× stimulation buffer containing 10 mM Hepes, 1 mM CaCl2, 0.5 mM MgCl2, 4.2 mM KCl, 146 mM NaCl, 5.5 mM glucose, and 50 mM LiCl, pH 7.4. After incubation, the reaction is stopped by adding a detection mixture consisting of lysis buffer and IP1-d2 and anti-IP1 cryptate diluted in 1× stimulation buffer. The plate is incubated at room temperature for 1 hour and then read on an EnVision® multimode plate reader to measure inositol phosphate levels.

[0307] Cisbio IP1 is a cell-based functional assay that quantifies the accumulation of inositol monophosphate (IP), a metabolite released as a result of orexin 2 receptor activation via the phospholipase C-Gq signaling pathway. This is a competitive immunoassay in which IP1 produced by cells upon receptor activation competes with an IP1 analog coupled to a d2 fluorophore (acceptor) for binding to an anti-IP1 monoclonal antibody labeled with Eu cryptate (donor). The measured HTRF-FRET-based signal is inversely proportional to the concentration of IP1 produced.

[0308] The EC reported in Table 2 50 values were obtained according to the above-described human OX2R IP1 assay. The data are mean EC 50 values ± S.E.M.
