| Bioactivity | (+)-sparteine (sulfate pentahydrate) is a ganglionic blocking agent. (+)-Sparteine competitively blocks nicotinic ACh receptor in the neurons[1]. |
| Target | nAChR |
| Invitro | (+)-Sparteine (2 μM) (sulfate pentahydrate) reduces the ACh-induced current caused by activation of nicotinic ACh receptors (AChRs) in a voltage-independent manner at membrane potentials of -50 mV to +30 mV, whereas its blocking effect increased at more negative membrane potentials. (+)-sparteine (5 μM and 10 μM) (sulfate pentahydrate) reduces the amplitude of the excitatory postsynaptic currents (EPSC) and the time constant of the EPSC decay[1]. |
