Icenticaftor (QBW251) is an oral enhancer of the cystic fibrosis transmembrane conductance regulator (CFTR) channel with an EC50 of 79 nM for F508del and 497 nM for G551D CFTR. Icenticaftor can be used in chronic obstructive pulmonary disease (COPD) and cystic fibrosis studies.
|Solubility (25°C)||DMSO ≥ 100 mg/mL|
Powder -20°C 3 years ; 4°C 2 years
In solvent -80°C 6 months ; -20°C 1 month
|Body Surface Area (m2)||0.007||0.025||0.15||0.05||0.02||0.5|
|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.
