S0859 — Datasheet

Biological Activity

S0859, an N-cyanosulphonamide compound, reversibly inhibit NBC-mediated pH(i) recovery (K (i)=1.7 microM, full inhibition at approximately 30 microM).NBCNa(+)-coupled HCO(3)(-) transporters (NBCs) mediate the transport of bicarbonate ions across cell membranes and are thus ubiquitous regulators of intracellular pH. NBC dysregulation is associated with a range of diseases; for instance, NBCn1 is strongly up-regulated in a model of ErbB2-dependent breast cancer, a malignant and widespread cancer with no targeted treatment options, and single-nucleotide polymorphisms in NBCn1 genetically link to breast cancer development and hypertension. Treatment with NBC inhibitor S0859 significantly increased caspase-3 activity and elevated the number of apoptotic EC. S0859 is potentially important for probing the transporter's functional role in heart and other tissues.

Published experimental findings depend on the model and assay conditions. They do not guarantee equivalent performance in every application. For laboratory research use only.
