Current treatments for insomnia, such as zolpidem (Ambien) and eszopiclone (Lunesta), are γ-aminobutyric acid type A (GABAA)-positive allosteric modulators that carry a number of side effects including the potential to disrupt cognition. In an effort to develop better tolerated medicines, we have identified dual orexin 1 and 2 receptor antagonists (DORAs),(More)
Androgen receptor (AR) ligands with tissue selectivity (selective androgen receptor modulators, or SARMs) have potential for treating muscle wasting, hypogonadism of aging, osteoporosis, female sexual dysfunction, and other indications. JNJ-28330835 is a nonsteroidal AR ligand with mixed agonist and antagonist activity in androgen-responsive cell-based(More)
Male rhesus monkeys secrete adult levels of androgen for 3 months postnatally. The role of this neonatal testicular secretion in sexual development was investigated by suppressing luteinizing hormone (LH) and testosterone (T) in neonatal male rhesus (n = 6) by administering a gonadotropin-releasing hormone agonist (Ag) for the first 4 months of postnatal(More)
Orexin (hypocretin) neuropeptides promote wakefulness by signaling through two G-protein coupled receptors, Orexin 1 Receptor (OX(1)R) and Orexin 2 Receptor (OX(2)R). MK-6096 is an orally bioavailable potent and selective reversible antagonist of OX(1)R and OX(2)R currently in clinical development for insomnia. In radioligand binding and functional cell(More)
Modulation of TASK-3 (Kcnk9) potassium channels affect neurotransmitter release in thalamocortical centers and other sleep-related nuclei having the capacity to regulate arousal cycles and REM sleep changes associated with mood disorders and antidepressant action. Circumstantial evidence from this and previous studies suggest the potential for TASK-3 to be(More)
PURPOSE To evaluate brain activity associated with sexual arousal, fully conscious male marmoset monkeys were imaged during presentation of odors that naturally elicit high levels of sexual activity and sexual motivation. MATERIAL AND METHODS Male monkeys were lightly anesthetized, secured in a head and body restrainer with a built-in birdcage resonator(More)
Dual orexin receptor antagonists (DORAs) are a potential treatment for insomnia that function by blocking both the orexin 1 and orexin 2 receptors. The objective of the current study was to further confirm the impact of therapeutic mechanisms targeting insomnia on locomotor coordination and ethanol interaction using DORAs and gamma-aminobutyric acid(More)
Insomnia is a common disorder that can be comorbid with other physical and psychological illnesses. Traditional management of insomnia relies on general central nervous system (CNS) suppression using GABA modulators. Many of these agents fail to meet patient needs with respect to sleep onset, maintenance, and next-day residual effects and have issues(More)
Drugs targeting insomnia ideally promote sleep throughout the night, maintain normal sleep architecture, and are devoid of residual effects associated with morning sedation. These features of an ideal compound are not only dependent upon pharmacokinetics, receptor binding kinetics, potency and pharmacodynamic activity, but also upon a compound’s mechanism(More)
