SUBSTITUTED PYRROLIDINYL AND PIPERIDINYL COMPOUNDS AND RELATED METHODS OF TREATMENT RELATED APPLICATION This application claims the benefit of U.S. Provisional patent application serial No.: 63/353,982, filed on June 21, 2022. The entire contents of the above-identified application are herein incorporated by reference. TECHNICAL FIELD The present invention relates to substituted pyrrolidinyl and piperidinyl compounds, particularly, substituted pyrrolidinyl and piperidinyl compounds having agonist activity. BACKGROUND OF THE INVENTION Orexin is a neuropeptide synthesized and released by a subpopulation of neurons within the lateral hypothalamus and its 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 expressed preferentially 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 a variety of 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). Narcolepsy is a neurological disease that results in excessive daytime sleepiness, sudden bouts of muscular paralysis (cataplexy), and disrupted sleep patterns (Mahoney et al., Nature Reviews Neuroscience, 2019). It is known that narcolepsy is caused by the degeneration of orexin neurons. Narcoleptic symptoms can be modeled in transgenic mice engineered to degenerate orexin neurons, and their symptoms can be reversed by intraventricular administration of orexin peptides (Proc. Natl. Acad. Sci. USA, Vol.101, 4649-4654, 2004). Studies of orexin-2 receptor knockout mice have suggested that the orexin-2 receptor plays a preferential role in maintaining wakefulness (Cell, Vol.98, 437- 451, 1999, Neuron, Vol.38, 715-730, 2003). As such, orexin-2 receptor agonists can be therapeutic agents for narcolepsy or other disorders exhibiting excessive daytime sleepiness, such as Parkinson’s disease (CNS Drugs, Vol.27, 83-90, 2013; Brain, Vol.130, 2007, 1586- 1595). A compound having agonist activity at the orexin-2 receptor is hypothesized to be useful as a novel therapeutic agent for narcolepsy, idiopathic hypersomnia, hypersomnia, sleep apnea syndrome, disturbance of consciousness such as coma and the like, narcolepsy syndrome, hypersomnolence syndrome characterized by hypersomnia (e.g., in Parkinson’s disease, Guillain-Barre syndrome or Kleine Levin syndrome), Alzheimer’s disease, obesity, insulin resistance syndrome, cardiac failure, diseases related to bone loss, or sepsis and the like. (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; WO 2015/073707; Journal of the American College of Cardiology, Vol.66, 2015, pages 2522-2533; WO 2015/048091; WO 2015/147240). Some compounds having orexin-2 receptor agonist activity have been reported (U.S. Pat. No.8,258,163; WO 2015/088000; WO 2014/198880; Journal of Medicinal Chemistry, Vol.58, pages 7931-7937; US 20190040010; US 20190031611; US 20170226137). However, it is considered that these compounds are not satisfactory, for example, in terms of activity, pharmacokinetics, permeability into the brain/central nervous system or safety, and the development of an improved compound having orexin-2 receptor agonist activity is desired.

Example 2: Human OX ₂ R IP1 assay T-Rex CHO cells stably overexpressing the human orexin-2 receptor (OX ₂ R) are induced overnight with 1 µg/mL of doxycycline in a T225 flask.24 hours post induction, cells are lifted with accutase and plated into a 384-well proxy plate at 30,000 cells/well. Cells are then treated with different test compounds in 1X stimulation buffer containing 10 mM Hepes, 1 mM CaCl ₂ , 0.5 mM MgCl ₂ , 4.2 mM KCl, 146 mM NaCl, 5.5 mM glucose, and 50 mM LiCl, pH 7.4, for 1 hr at 37 degrees C. Following incubation, the reaction is terminated by the addition of detection mix, which is composed of IP1-d2 and anti-IP1-cryptate diluted in lysis buffer as well as 1X stimulation buffer. The plates are allowed to incubate for 1 hour at room temperature and are then read in the EnVision® multimode plate reader, measuring inositol phosphate levels. Cisbio IP1 is a cell-based functional assay quantifying the accumulation of inositol monophosphate (IP), a metabolite released as a result of orexin 2 receptor activation through the phospholipase C-Gq signaling pathway. This is a competitive immunoassay in which the IP1 produced by the cells upon receptor activation competes with the IP1 analog coupled to the 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 IP1 concentration produced. The EC50 values reported in Table 2 were obtained according to the human OX2R IP1 assay described above. Data are the mean EC ₅₀ values ± S.E.M. Table 2.
