Description: Chloride channel blocker; TRPV1 modulator; RAD51 recombinase inhibitor
Chemical Name: 4,4'-Diisothiocyanato-2,2'-stilbenedisulfonic acid disodium salt
Purity: ≥95% (HPLC)
Biological Activity for DIDS
DIDS is a ClC-Ka chloride channel blocker (IC50 = 100 μM). Blocks the maxi chloride channel in apical membranes from human placenta. Displays antagonistic activity at TRPM4 and TRPC4 channels; potentiates agonist-induced TRPV1 currents (IC50 = 4.88 μM in rat DRG neurons). Inhibits RAD51 recombinase activity (KD = 2 μM).
