Biological Activity

Glibenclamide (Glyburide) is an orally active ATP-sensitive K+ channel (KATP) inhibitor. Glibenclamide inhibits P-glycoprotein. Glibenclamide directly binds and blocks the SUR1 subunits of KATP and inhibits the cystic fibrosis transmembrane conductance regulator protein (CFTR). Glibenclamide interferes with mitochondrial bioenergetics by inducing changes on membrane ion permeability. Glibenclamide can also induce autophagy.

Glibenclamide (2 mg/kg; p.o.) increases of insulin release and rapid drop of blood glucose level in mice.

Conversion of different model animals based on BSA (PMID: 27057123)
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.

Guanosine 3′,5′-cyclic monophosphate

Guanosine 3′,5′-cyclic monophosphate (cGMP) acts as an important second messenger, cGMP is a major intracellular mediator of extracellular signals such as nitric oxide and natriuretic peptides. Cyclic GMP interacts with three types of intracellular receptor proteins: cGMP-dependent protein kinases, cGMP-regulated channels, and cGMP-regulated cyclic nucleotide phosphodiesterases. A primary action of elevated cGMP levels in vivo is the stimulation of cGMP-dependent protein kinase (PKG).
