Verkningsmekanism (Mechanism of Action)

Egenskaper
The first potent and orally available CFTR potentiator to enter human clinical trials.
Targets/IC50/Ki
F508del-CFTR
(Fisher rat thyroid cells)
25 nM(EC50)
G551D-CFTR
(Fisher rat thyroid cells)
100 nM(EC50)
In vitro

Ivacaftor (VX-770) (10 μM) significantly increases the forskolin-stimulated Cl- secretion (IT) by ~4-fold with an EC50 of 100 nM in the recombinant Fisher rat thyroid (FRT) cells expressing G551D gating mutation of CFTR, and by ~6-fold with an EC50 of 25 nM in the recombinant cells expressing temperature-corrected F508del processing mutation of CFTR. Consistent with the increases in the forskolin-stimulated IT, this compound increases the open probability (Po) of G551D-, F508del-, and wild-type CFTR by ~6-fold, ~5-fold and ~2-fold, respectively, indicating that it acts directly on CFTR to increase its gating activity. In primary cultured human CF bronchial epithelia (HBE) carrying the G551D and F508del CFTR mutations, Ivacaftor potently increases the forskolin-stimulated IT by ~10-fold from 5% to a maximum level of 48% of that measured in non-CF HBE, with an EC50 of 236 nM displaying ~70-fold more potency compared with the commonly used CFTR potentiator genistein, which has an EC50 of 16 μM. In HBE with F508del homozygous CFTR, it causes a significant increase in the forskolin-stimulated IT with an EC50 of 22 nM, to a less extent from 4% to 16% of non-CF HBE compared with the effect in G551D/F508del HBE. Due to CFTR potentiation, this compound inhibits excessive ENaC-mediated Na+ and fluid absorption with an IC50 of 43 nM, and decreases the response, resulting in an increase in the surface fluid and cilia beat frequency (CBF) in G551D/F508del HBE.

Kinasanalys
Ussingkammarinspelningar
Effekten av Ivacaftor (VX-770) på CFTR-medierad Cl--sekretion karakteriseras genom att mäta den CFTR-medierade IT i kammare med rekombinanta Fisher-råttsköldkörtelceller (FRT) som uttrycker G551D eller F508del CFTR. Celler odlas på Costar Snapwell-cellodlingsinsatser som hålls vid 37 °C före inspelning. Cellodlingsinsatserna monteras i en Ussingkammare för att registrera IT i spänningsklämningsläget (Vhold = 0 mV). För FRT-celler etableras basolaterala membranet som en basolateral till apikal Cl--gradient. Den basolaterala badlösningen innehåller 135 mM NaCl, 1,2 mM CaCl2, 1,2 mM MgCl2, 2,4 mM K2HPO4, 0,6 mM KHPO4, 10 mM N-2-hydroxietyldipiperazin-N
