体外研究 (In Vitro) | The benzopyrimido-pyrrolo-oxazinedione BPO-27 is an analogue of PPQ-102, which inhibits CFTR with an IC50of 8 nM. The R enantiomer of BPO-27 inhibits CFTR chloride conductance with an IC50of 4 nM, while S enantiomer is inactive.In vitrometabolic stability in hepatic microsomes shows both enantiomers as stable, with less than 5% metabolism in 4 h[1]. (R)-BPO-27 binds near the canonical ATP binding site. Whole-cell patch-clamp studies shows linear CFTR currents with a voltage-independent (R)-BPO-27 block mechanism. At a concentration of (R)-BPO-27 that inhibits CFTR chloride current by 50%, the EC50for ATP activation of CFTR increases from 0.27 to 1.77 mM[2]. | ||||||||||||||||
