VU0119498 is a pan Gq mAChR M1, M3, M5 positive allosteric modulator (PAM), with EC50s of 6.04, 6.38, and 4.08 µM, respectively. VU0119498 has antidiabetic activity[1][2][3].

VU0119498 (0.01-30 μM; 150s) potentiates 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) augments ACh-mediated increases in insulin secretion and intracellular calcium levels in MIN6-K8 cells[3].VU0119498 (20 μM; 90 min) enhances ACh-induced insulin release in mouse and human pancreatic islets[3].

VU0119498 (0.1-2 mg/kg; a single i.p.) improves glucose tolerance and insulin secretion in mice in a β-cell M3R-dependent fashion[3].VU0119498 (0.5 mg/kg; a single i.p.) improves glucose tolerance and insulin secretion in obese, glucose-intolerant mice[3]. Animal Model: Male WT mice (12 weeks)[3]
