mAChR M5 ( IC50 = 4.1 μM ); mAChR M1 ( IC50 = 6.1 μM ); mAChR M3 ( IC50 = 6.4 μM )
VU0119498 targets the M1, M3, and M5 subtypes of muscarinic acetylcholine receptors (mAChRs), which are G protein-coupled receptors that signal through the Gq pathway. As a positive allosteric modulator (PAM), VU0119498 binds to an allosteric site on the receptor, distinct from the orthosteric (acetylcholine) binding site. This binding enhances the receptor's response to acetylcholine, potentiating its signaling without directly activating the receptor itself. |

| ln Vitro |
VU0119498 (0.01-30 μM; 150 s) amplifies Ach responses in M1, M3, and M5-expressing CHO cells, with EC50s of 6.04, 6.38, and 4.08 µM, respectively[1].
VU0119498 (3–20 μM) enhances ACh-mediated increases in insulin secretion and intracellular calcium levels in MIN6-K8 cells[3]. VU0119498 (20 μM; 90 min) improves ACh-induced insulin release in mouse and human pancreatic islets[3]. In vitro, VU0119498 (0.01-30 µM; 150 seconds) amplifies acetylcholine (ACh) responses in M1, M3, and M5-expressing CHO cells, with EC50s of 6.04, 6.38, and 4.08 µM, respectively. VU0119498 (3–20 µM) enhances ACh-mediated increases in insulin secretion and intracellular calcium levels in MIN6-K8 cells. VU0119498 (20 µM; 90 minutes) improves ACh-induced insulin release in mouse and human pancreatic islets. |
| ln Vivo |
VU0119498 (0.1-2 mg/kg; a single i.p.) enhances insulin secretion and glucose tolerance in mice in a β-cell M3R-dependent manner[3].
VU0119498 (0.5 mg/kg; a single intraperitoneal; I.P.) enhances both glucose tolerance and insulin secretion in obese, glucose-intolerant mice[3]. In vivo, VU0119498 (0.1-2 mg/kg; a single i.p.) enhances insulin secretion and glucose tolerance in mice in a β-cell M3R-dependent manner. VU0119498 (0.5 mg/kg; a single i.p.) enhances both glucose tolerance and insulin secretion in obese, glucose-intolerant mice. These findings demonstrate its antidiabetic potential. |
| Enzyme Assay |
In vitro receptor binding/functional assays for VU0119498 are performed using cells (e.g., CHO cells) expressing human M1, M3, or M5 mAChRs. Cells are loaded with a calcium-sensitive dye and stimulated with a submaximal concentration of acetylcholine in the presence of various concentrations of VU0119498. The potentiation of the calcium response is measured fluorometrically. EC50 values for PAM activity are calculated from dose-response curves.
|
| Cell Assay |
Cellular assays for VU0119498 use MIN6-K8 pancreatic β-cells or mouse/human pancreatic islets. Cells are treated with VU0119498 (3-20 µM) in the presence of acetylcholine. Insulin secretion is measured by ELISA or radioimmunoassay. Intracellular calcium levels are measured using a calcium-sensitive dye. These assays confirm the compound's ability to enhance glucose-stimulated insulin secretion.

| Animal Protocol |
Male WT mice (12 weeks)
0.1, 0.5, 2 mg/kg A single i.p. In vivo animal studies for VU0119498 are conducted in male wild-type mice (12 weeks) or obese, glucose-intolerant mice. VU0119498 is administered as a single intraperitoneal (i.p.) injection at doses of 0.1, 0.5, or 2 mg/kg. Glucose tolerance tests are performed, and insulin secretion is measured. Efficacy is compared to vehicle-treated mice. |
| ADME/Pharmacokinetics |
VU0119498 has a molecular weight of 316.15 g/mol and a molecular formula of C15H10BrNO2. It is an orange to red solid powder. It is typically stored as a powder at -20°C for up to 3 years or in solvent at -80°C for up to 1 year. It is soluble in DMSO. Pharmacokinetic properties such as oral bioavailability and brain penetration would be determined in preclinical studies.
|
| Toxicity/Toxicokinetics |
Preclinical toxicity of VU0119498 would be evaluated in standard toxicology studies. As a PAM of muscarinic receptors, potential adverse effects may include cholinergic side effects such as increased salivation, lacrimation, and gastrointestinal motility. In animal studies, it has shown efficacy in enhancing glucose tolerance at doses of 0.1-2 mg/kg. Comprehensive toxicity data is not widely available.
