体外研究
(In Vitro)

BQCA reduces the concentration of ACh required to activate M1 up to 129-fold with an inflection point value of 845 nM. No potentiation, agonism, or antagonism activity on other mAChRs is observed up to 100 μM[1]. BQCA increases M1 receptor affinity for acetylcholine. The activation of the M1 receptor by BQCA induces a robust inward current and increases spontaneous excitatory postsynaptic currents in medial prefrontal cortex (mPFC) pyramidal cells[2].

体内研究
(In Vivo)

BQCA requires M1 to promote inositol phosphate turnover in primary neurons and to increase c-fos and arc RNA expression and ERK phosphorylation in the brain. BQCA reverses scopolamine-induced memory deficits in contextual fear conditioning, increases blood flow to the cerebral cortex, and increases wakefulness while reducing delta sleep. BQCA induces β-arrestin recruitment to M1, suggesting a role for this signal transduction mechanism in the cholinergic modulation of memory[1]. BQCA increases firing of mPFC pyramidal cells in vivo. BQCA also restores discrimination reversal learning in a transgenic mouse model of Alzheimer's disease[2].

Kinase Assay
[1]

Competition binding reactions used 25 μg human M1 CHO membrane protein, BQCA or vehicle, and 0.15 nM [3H]NMS in 96-well deep-well plates. Binding reactions (30 °C for 2-3 h) are terminated by rapid filtration. Nonspecific binding is determined by adding 10 μM atropine. Filter plates are ished 4×with ice-cold 20 mM HEPES, 100 mM NaCl, and 5 mM MgCl2, pH 7.4 using a 96-well harvester. Plates are dried and radioactivity counted with a microplate scintillation counter[1].

Animal Administration
[1][2]

Rats: Male Sprague-Dawley rats weighing 225-250 g, are injected i.p. with the micro-suspension (containing 10% tween 80) of BQCA at the dose of 10 mg/kg. The blood and whole brain tissue samples are collected at 0.5, 1, 2, 4 and 8 h. Blood samples are collected through cardiac puncture in EDTA vacutainer tubes. The plasma is separated by centrifugation and stored at −80°C until analysis. The animals are decapitated and the whole brain tissue are removed and immediately frozen on dry ice[2].

Mice: Mice are dosed I.P. with BQCA in 5% beta-cyclodextrin and/or 0.3 mg/kg scopolamine in 0.9% saline 30 min before placement into a chamber for 2 min before 2 tone-footshock pairings (3 kHz, 85 dB tone for 30 s co-terminated with a 0.5 mA, 1 s shock) 2 min apart. Mice are removed to their home cage 30 s after the last pairing. Twenty-four hours later mice are placed into the same chamber and freezing is measured by Video Freeze[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
