CACC BLOCKER IV BENZBROMARONE (C005B-228600)

General description

A cell-permeable uricosuric agent that, in addition to its known efficacy in gout treatment, acts as a reversible CaCC blocker and is reported to be more potent than NFA (Cat. No. 481987) and NPPB (Cat. No. 484100) in suppressing 500 nM Ionomycin- (Cat. Nos. 407950, 407952, and 407953) induced I^- influx in TMEM16A-expressing HEK293 cells (IC₅₀ = 9.97, 140, and 150 µM, respectively) as well as in blocking voltage-gated Cl^- current in TMEM16B-expressing HEK293 (64% inhibition with 10 µM BBR vs. 47% inhibition with 300 µM NFA; by whole cell patch clamp), while exhibiting much reduced potency against voltage-gated current via ENaC (α, β, and γ) or CFTR (by 25% and 17% with 10 µM BBR, respectively, using HEK293 ENaC or CFTR transfectants). Shown to significantly reduce 100 µM ATP-induced CaCC current (IAC current = 1.137 vs. 3.099 µA/cm² with or without 10 µM BBR) and mucin secretion from NHBE (normal human bronchial epithelial) as well as suppress human ASM (airway smooth muscle) contraction upon muscarinic receptor stimulation.
