Dehydroepiandrosterone sulfate can partially penetrate the blood-brain barrier, inhibit GABA_A receptor-mediated chloride influx, enhance NMDA receptor activity through σ₁ receptors, exert anti-inflammatory, anti-glucocorticoid and antidepressant effects, and increase convulsive sensitivity. Dehydroepiandrosterone sulfate participates in neuroprotection, neurite growth regulation and catecholamine secretion regulation, and can be used in the study of depression, post-traumatic stress disorder (PTSD), Alzheimer's disease, etc. Dehydroepiandrosterone sulfate may also be a biomarker for cardiovascular disease mortality, and its concentration is independently and negatively correlated with mortality .

(Z)-Thiothixene-d8

(Z)-Thiothixene-d₈ (NSC 108165-d₈; Navan-d₈; Navane-d₈) is the deuterium labeled Thiothixene (HY-A0139). Thiothixene is a typical antipsychotic. It selectively binds to dopamine D2 over D1, D3, and D4 receptors (Kis=0.417, 338, 186.2, and 363.1 nM, respectively). Thiothixene also binds to various serotonin (5-HT), histamine H1, α1- and α2-adrenergic, muscarinic acetylcholine, and sigma receptors (Kis=15-5,754 nM) as well as the dopamine, norepinephrine, and serotonin transporters (Kis=3.16-30 μM). In vivo, thiothixene reduces spontaneous and amphetamine-induced locomotor activity in rats. It enhances latent inhibition, as measured by a decreased lick latency in response to light and foot shock stimuli, which is a measure of selective attention in rats.3 Thiothixene also increases competitive behavior in submissive mice, indicating antidepressant-like behavior.
