SPT-320, also formerly known as LYT-320, is a prodrug of agomelatine which is under development for the treatment of mood and anxiety disorders, for instance generalized anxiety disorder. [1] [2]

As an agomelatine prodrug, it acts as a melatonin receptor agonist and as a serotonin 5-HT2B and 5-HT2C receptor antagonist. [1] [2] The drug is taken by mouth and is said to bypass first-pass hepatic metabolism. [1] [2]

As of December 2023, SPT-320 is in the preclinical research phase of development. [1] [2] It is under development by Seaport Therapeutics and is being developed towards approval in the United States. [1] [2] The chemical structure of SPT-320 does not yet appear to have been disclosed. [1]

Fluvoxamine, sold under the brand name Luvox among others, is an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class. It is primarily used to treat major depressive disorder and, perhaps more-especially, obsessive–compulsive disorder (OCD), but is also used to treat anxiety disorders such as panic disorder, social anxiety disorder, and post-traumatic stress disorder.

<span class="mw-page-title-main">Buspirone</span> Medication used to treat anxiety disorders

Buspirone, sold under the brand name Buspar among others, is an anxiolytic, a medication primarily used to treat anxiety disorders, particularly generalized anxiety disorder (GAD). It is a serotonin 5-HT1A receptor partial agonist, increasing action at serotonin receptors in the brain. It is taken orally and takes two to six weeks to be fully effective.

Riluzole is a medication used to treat amyotrophic lateral sclerosis (ALS) and other motor neuron diseases. Riluzole delays the onset of ventilator-dependence or tracheostomy in some people and may increase survival by two to three months. Riluzole is available in tablet and liquid form.

<span class="mw-page-title-main">Agomelatine</span> Atypical antidepressant classified primarily as a melatonin receptor agonist

Agomelatine, sold under the brand names Valdoxan and Thymanax, among others, is an atypical antidepressant most commonly used to treat major depressive disorder and generalized anxiety disorder. One review found that it is as effective as other antidepressants with similar discontinuation rates overall but fewer discontinuations due to side effects. Another review also found it was similarly effective to many other antidepressants.

Alpidem, sold under the brand name Ananxyl, is a nonbenzodiazepine anxiolytic medication which was briefly used to treat anxiety disorders but is no longer marketed. It was previously marketed in France, but was discontinued due to liver toxicity. Alpidem is taken by mouth.

<span class="mw-page-title-main">Lofepramine</span> Chemical compound

Lofepramine, sold under the brand names Gamanil, Lomont, and Tymelyt among others, is a tricyclic antidepressant (TCA) which is used to treat depression. The TCAs are so named as they share the common property of having three rings in their chemical structure. Like most TCAs lofepramine is believed to work in relieving depression by increasing concentrations of the neurotransmitters norepinephrine and serotonin in the synapse, by inhibiting their reuptake. It is usually considered a third-generation TCA, as unlike the first- and second-generation TCAs it is relatively safe in overdose and has milder and less frequent side effects.

<span class="mw-page-title-main">Opipramol</span> Drug used to treat depressive and anxiety disorders

Opipramol, sold under the brand name Insidon among others, is an anxiolytic and tricyclic antidepressant that is used throughout Europe. Despite chemically being a tricyclic dibenzazepine (iminostilbene) derivative similar to imipramine, opipramol is not a monoamine reuptake inhibitor like most other tricyclic antidepressants, and instead, uniquely among antidepressants, acts primarily as a SIGMAR1 agonist. It was developed by Schindler and Blattner in 1961.

<span class="mw-page-title-main">Desmetramadol</span> Opioid painkiller medication

Desmetramadol, also known as O-desmethyltramadol (O-DSMT), is an opioid analgesic and the main active metabolite of tramadol. Tramadol is demethylated by the liver enzyme CYP2D6 to desmetramadol in the same way as codeine, and so similarly to the variation in effects seen with codeine, individuals who have a less active form of CYP2D6 will tend to have reduced analgesic effects from tramadol. Because desmetramadol itself does not need to be metabolized to induce an analgesic effect, it can be used in individuals with CYP2D6 inactivating mutations.

Vortioxetine, sold under the brand name Trintellix and Brintellix among others, is an antidepressant of the serotonin modulator and stimulator (SMS) class. Its effectiveness is viewed as similar to that of other antidepressants. It is taken orally.

An orexin receptor antagonist, or orexin antagonist, is a drug that inhibits the effect of orexin by acting as a receptor antagonist of one (selective orexin receptor antagonist or SORA) or both (dual orexin receptor antagonis or DORA) of the orexin receptors, OX1 and OX2. Medical applications include treatment of sleep disorders such as insomnia.

<span class="mw-page-title-main">Hydroxybupropion</span> Group of stereoisomers

Hydroxybupropion, or 6-hydroxybupropion, is the major active metabolite of the antidepressant and smoking cessation drug bupropion. It is formed from bupropion by the liver enzyme CYP2B6 during first-pass metabolism. With oral bupropion treatment, hydroxybupropion is present in plasma at area under the curve concentrations that are as many as 16 to 20 times greater than those of bupropion itself, demonstrating extensive conversion of bupropion into hydroxybupropion in humans. As such, hydroxybupropion is likely to play a very important role in the effects of oral bupropion, which could accurately be thought of as functioning largely as a prodrug to hydroxybupropion.
