Chemical Name: 1,4-Dihydro-1-[(4-methoxyphenyl)methyl]-4-oxo-3-quinolinecarboxylic acid
Biological ActivityBQCA is a muscarinic M1 receptor positive allosteric modulator (pKB 5.76 - 5.82). Exhibits selectivity for M1 over M3 and M5 receptors. Enhances ACh effects at M1 receptors in an IP1- accumulation assay, without affecting ACh binding. Increases markers of neuronal activation in brains of wild-type but not M1-/- mice in vivo. Prevents Scopolamine (Cat. No. 1414)-induced memory deficits in mice in a contextual fear conditioning model.
