|July 1, 1979
Summary
RU 31158, a novel compound, exhibits potent hypnotic effects in mice and rats, significantly outperforming diazepam. This drug also demonstrates promising anxiolytic and anticonvulsant properties.
Area of Science:
- Pharmacology
- Neuroscience
- Medicinal Chemistry
Background:
- Benzodiazepines are widely used for their sedative and anxiolytic effects.
- Diazepam is a common reference drug in hypnotic and anxiolytic research.
- Novel compounds are continuously sought to improve therapeutic profiles and reduce side effects.
Purpose of the Study:
- To evaluate the hypnotic activity of RU 31158 in comparison to diazepam.
- To assess the anxiolytic, anticonvulsant, and tranquilizer properties of RU 31158.
- To characterize the dose-response and duration of action of RU 31158.
Main Methods:
- Animal models (mice and rats) were used to test hypnotic, anxiolytic, and anticonvulsant activities.
- Potentiation of hypnosis induced by hexobarbital and chlorprothixene was measured.
- ED50 values were calculated for RU 31158 and diazepam.
- Sleep duration studies were conducted in rats.
Main Results:
- RU 31158 demonstrated significantly more potent hypnotic activity than diazepam in both mice and rats.
- ED50 values for RU 31158 were considerably lower than diazepam for hypnotic potentiation.
- Sleep studies confirmed hypnotic effects with a duration not exceeding 9 hours.
- RU 31158 exhibited potent minor tranquilizer, anxiolytic, and anticonvulsant properties.
Conclusions:
- RU 31158 possesses superior hypnotic efficacy compared to diazepam.
- The compound shows a broad spectrum of central nervous system depressant activities.
- RU 31158 represents a promising candidate for further pharmacological investigation.

01:14CNS Depressants: Barbiturates and Benzodiazepines
CNS depressants include drugs from the category of barbiturates and benzodiazepines. They are valuable medications for managing anxiety disorders and insomnia. Barbiturates, once used to induce and maintain sleep, have been replaced mainly by benzodiazepines due to barbiturate's toxicity, tolerance, and overdose risks. They interact with GABAA receptors, leading to sedation at low doses and potentially coma and death at higher doses. Phenobarbital, a long-acting barbiturate, possesses...
01:23Sedatives and Hypnotics: Overview
Sedatives are drugs that alleviate anxiety, while hypnotics induce sleep. Both classes of medication suppress neuronal activity, leading to a calming effect for sedatives and facilitating sleep for hypnotics.
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

01:19Management of Insomnia
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...
01:20Sedatives and Hypnotics Drugs: Barbiturates
Sedatives and hypnotics encompass a drug class that acts on the central nervous system (CNS) to alleviate anxiety, promote relaxation and induce sleep.These drugs function by amplifying the actions of the neurotransmitter γ-aminobutyric acid (GABA), resulting in reduced neuronal activity. Barbiturates, a subset of sedatives and hypnotics first synthesized in the late 1800s, are categorized into ultra-short, short, intermediate, and long-acting groups based on their duration of effect. A key...
01:19Sedatives and Hypnotics Drugs: Benzodiazepines
Benzodiazepines have both sedative and hypnotic properties. They include compounds such as diazepam (Valium) and alprazolam (Xanax). Structurally, their cores are similar, consisting of the fusion of a benzene ring and a diazepine ring, but they share a common mechanism of action in the central nervous system (CNS).
Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...

01:17Sedatives and Hypnotics Drugs: Miscellaneous Agents
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
