Biological Activity

(+)-Bicuculline (1-100μM) dose-dependently inhibits the Cl- conductance generated by 40 μM GABA. (+)-Bicuculline inhibits GABA(A) α2/β1/γ2 currents activated by γ-Aminobutyric acid, (+)-Bicuculline concentration from 10 nM to 2 μM progressively decreased the amplitude of GABA-activated ion currents. Furthermore, (+)-bicuculine also blocks small-conductance calcium-activated potassium channels.

Protocol
Cell Experiment
Cell lines Primary cortical neurons from rat E18 embryos
Preparation method Bicuculline treatment could potentiate synaptic NMDAR signaling in the primary cortical neurons. Bicuculline led to a rapid decrease in STEP61 expression and a concomitant increase in the tyrosine phosphorylation of STEP substrates including GluN2B, Pyk2, and ERK1/2.
Concentrations 10 μM
Incubation time 15-60 min
Animal Experiment
Animal models Fischer-344 virgin female rats of Ovariectomy
Formulation sesame oil + 10% DMSO
Dosages 3.5 mg/kg daily
Administration via osmotic subcutaneous pumps
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
