Product Introduction
Bioactivity


英文名: AVN-492

描述: AVN-492 是一种有效的选择性 5-HT6R 拮抗剂，Ki 为 91 pM。

激酶实验: Assessment of AVN-492 selectivity was performed on a panel of 69 therapeutic targets including receptors, ion channels, neuromediator transporters, and enzymes. The full list of the targets is presented in the Supplementary Material. AVN-492 interactions with therapeutic targets were assessed by either equilibrium competitive displacement of corresponding radiolabeled ligands or inhibition of corresponding enzymatic activities. The studies were performed at Eurofins in accordance with their internally optimized procedures as briefly described in. The displacement of radioligands and inhibition of enzymatic activities were measured at AVN-492 concentration of 1 M in duplicates. Affinities of AVN-492 to both the 5-HT6R and 5-HT2BR were assessed in an equilibrium competitive [3H]LSD displacement assay. AVN-492 was provided at different concentrations and [3H]LSD was kept at a concentration of 1.50 nM for 5-HT6R, or 1.20 nM for 5-HT2BR. The ligands were added to corresponding receptor-membrane suspensions (plasma membranes obtained from engineered HeLa cells expressing recombinant human 5-HT6R or engineered CHO-K1 cells expressing recombinant human 5-HT2BR). The cell membrane/ligands mixtures were incubated in buffer of the following composition: For 5-HT6R: 50 mM Tris-HCl, pH 7.4, 150 mM NaCl, 2 mM ascorbic acid, 0.001% BSA – 120 min at 37?C; for 5-HT2BR: 50 mM Tris-HCl, pH 7.4, 4 mM CaCl2, 0.1% ascorbic acid – 60 min at 37?C. Specific radio-ligand binding was measured as a difference between total binding and binding in the presence of excessive concentration of cold serotonin [1].

动物实验: For pharmacokinetic, behavior, and toxicity studies, male Wistar rats (220–242 g), male CD1 mice (24–30 g), male SHK mice (20–25 g), and male Balb/C mice (15–20 g) were used. Rodents were obtained from Jackson Laboratories and housed in a standard laboratory animal facility in groups of 5–7 animals per cage. Before entering the investigation, the animals were acclimated at least for seven days. Obese C57BL/6 male 18-week-old mice were obtained from Jackson Laboratories. The mice were fed on a high-fat diet (60% kcal Research Diet 12492i) from the age of 6 weeks. Upon arrival, the mice were maintained on the same high fat diet with free access to both food and water. The mice were individually housed in solid bottom static isolators with Bed-O'Cobs? bedding inside a BioBUBBLE? clean room that provided HEPA-filtered air into the clean room environment at a rate of 100 complete air changes per hour. All treatments and procedures including body weight determinations, drug administration, and glucose measurements were carried out in the clean room environment [1].

体外活性: Affinity of AVN-492, Ki^b, to compete with [3H]LSD for binding to 5-HT6R was estimated to be 91 pM (IC50^b = 194 pM). Affinity of 509 AVN-492 to the 5-HT2BR, Ki^b = 170 nM (IC50^b = 268 nM) was more than three orders of magnitude lower. Despite being metabolized by human microsomes, AVN-492 did not appreciably inhibit five major human recombinant CYP isoforms, CYP3A4, 1A2, 2C9, 2C19, and 2D6 at concentrations as high as 10 M [1].

体内活性: AVN-492 has high oral bioavailability and good brain permeability in rodents. In behavioral tests, AVN-492 shows an anxiolytic effect in the elevated plus-maze model, prevents an apomorphine-induced disruption of startle pre-pulse inhibition (the PPI model) and reverses scopolamine- and MK-801-induced memory deficit in passive avoidance model. No anti-obesity effect of AVN-492 was found in a murine model [1].
