PRX-07034 hydrochloride is a selective antagonist of 5-HT6 receptor. It has cognition and memory-enhancing properties and potently decreases food intake and body weight in rodents. PRX-07034 hydrochloride is both a potent (Ki = 4-8 nM) and highly selective 5-HT(6) receptor antagonist (≥100-fold selectivity for the 5-HT(6) receptor compared to 68 other GPCRs, ion channels, and transporters, except D(3) (Ki = 71 nM) and 5-HT(1B) (Ki = 260 nM) receptors.

Rivanicline hemioxalate, also known as RJR-2403 hemioxalate or (E)-Metanicotine hemioxalate, is a chemical compound acting as a neuronal nicotinic receptor agonist with pronounced selectivity for the α4β2 receptor subtype, showing over 1,000-fold greater selectivity for this subtype (Ki=26 nM) compared to α7 receptors (Ki=3.6 μM). Its in vitro studies demonstrate no significant activation of nAChRs in PC12 cells, muscle type nAChRs, or muscarinic receptors at concentrations up to 1 mM. Furthermore, Rivanicline displayed less than one-tenth the potency of nicotine in inducing ileum contraction, with substantially lower efficacy, and failed to antagonize nicotine-induced stimulation of muscle or ganglionic nAChR functions, with an IC50 value greater than 1 mM. Chronic exposure to Rivanicline at 10 microM led to up-regulation of high-affinity nAChRs in M10 cells, mimicking effects observed with nicotine. In vivo studies revealed that Rivanicline significantly reversed scopolamine-induced amnesia and improved working and reference memory in a rat model, while being 15 to 30 times less potent than nicotine in affecting body temperature, respiration, and other physiological responses. Metanicitone's potency was approximately five times lower than nicotine in tail-flick tests following subcutaneous administration, yet slightly more potent upon central administration.

Ipramidil (C80-1324) reveals marked dilator activity in the coronary circulation of isolated working hearts.

Obidoxime dichloride is a detoxifying agent for organophosphorus poisoning, enhancing the positive inotropic effect of phosphamidon on isolated working rat hearts.

β-CCM is a benzodiazepine receptor inverse agonist with anxiogenic and convulsant effects. It enhances emotional reactivity and reduces interference sensitivity in spatial working memory tasks. β-CCM is applicable in research related to anxiety disorders.

NF-κB-IN-20 is an orally bioavailable inhibitor of NF-κB. By binding directly to the Keap1 protein, NF-κB-IN-20 activates the Keap1/Nrf2/HO-1 antioxidant pathway and concurrently inhibits the NF-κB inflammatory pathway, working synergistically to reduce oxidative stress and inflammation. Additionally, NF-κB-IN-20 M11 suppresses the expression of IL-6, IL-1β, and TNF-α, significantly decreases ROS levels, and restores mitochondrial membrane potential. This compound is applicable in studies of acute lung injury (ALI).

Prasterone is an endogenous steroid hormone. Prasterone acts as an agonist at ERβ, NMDA, and σ1 receptors, a partial agonist at ERα and AR, and antagonist at GABA-A receptors. It displays a variety of biologocial activities, including enhancing working me

Guanfacine-13C,15N3 is intended for us as an internal standard for the quantification of guanfacine by GC- or LC-MS. Guanfacine (T22824) is an α2-adrenergic receptor (α2-AR) agonist with Kivalues of 93, 1,380, and 3,890 nM for α2A-, α2B-, and α2C-ARs, respectively, in a radioligand binding assay.1It has EC50values of 52, 288, and 602 nM for α2A-, α2B-, and α2C-ARs, respectively, for stimulated [35S]GTPγS binding. It also binds to imidazoline receptor 1 (Ki= 19 nM in a radioligand binding assay).2Guanfacine (0.3-5 mg/kg) binds to adrenergic receptors in the central nervous system and lowers blood pressure in hypertensive rats in a dose-dependent manner.3It also improves spatial working memory deficits induced by hypobaric hypoxia in rats.4Formulations containing guanfacine are used in the treatment of high blood pressure and attention deficit hyperactivity disorder (ADHD).

CY208-243 is a D1 agonist. CY208-243 attenuates the pattern electroretinogram to low spatial frequency stimuli in the monkey. CY208-243 stimulates adenylate cyclase in rat striatal homogenates with an EC50 of 125 nM. CY208,243 was superior in improving the strength of neuronal outcome sensitivity to the working memory-related choice behavior in the T-maze.
