Potassium Channel
KcsA
Potassium channels are the most widely distributed type of ion channel and are found in virtually all living organisms. They form potassium-selective pores that span cell membranes. Potassium channels are found in most cell types and control a wide variety of cell functions. Potassium channels function to conduct potassium ions down their electrochemical gradient, doing so both rapidly and selectively. Biologically, these channels act to set or reset the resting potential in many cells. In excitable cells, such asneurons, the delayed counterflow of potassium ions shapes the action potential. By contributing to the regulation of the action potential duration in cardiac muscle, malfunction of potassium channels may cause life-threatening arrhythmias. Potassium channels may also be involved in maintaining vascular tone.

ShK toxin TFA
0 ImagesCat. No.: HY-P3071ASynonyms: Stichodactyla helianthus neurotoxin TFAShK toxin TFA (Stichodactyla helianthus neurotoxin TFA) is a neurotoxin. ShK toxin TFA blocks voltage-dependent potassium channel (Kv1.3 channel). ShK toxin TFA can be isolated from the whole body extract of the Caribbean sea anemone (Stichodactylu helianthus). ShK toxin TFA competes with dendrotoxin I and α-dendrotoxin for binding to synaptosomal membranes of rat brain, facilitates acetylcholine release. ShK toxin TFA suppresses K+ currents in cultured rat dorsal root ganglion neurons. ShK toxin TFA also inhibits T lymphocyte proliferation.

Fenquizone
0 ImagesSynonyms: MG-13054Fenquizone (MG-13054) is an orally active diuretic. Fenquizone acts primarily on the diluting segment of the nephron cortex, similar to thiazide diuretics. Fenquizone demonstrates diuretic and natriuretic potency and duration of action comparable to thiazide diuretics but weaker than loop diuretics. Fenquizone reduces CH₂O without affecting TCH₂O, does not increase calcium/phosphate excretion, and has no loop or collecting duct effects. Fenquizone is used in the study of edema and hypertension.

Vm24-toxin TFA
0 ImagesCat. No.: HY-P5917ASynonyms: Vaejovis mexicanus peptide 24 TFAVm24-toxin (Vaejovis mexicanus peptide 24) TFA, a 36-residue peptide, is a potent and selective Kv1.3 blocker with a Kd of ~3 pM in lymphocytes. Vm24-toxin TFA shows >1500-fold affinity for Kv1.3 over other assayed potassium channels. Vm24-toxin TFA folds into a distorted cystine-stabilized α/β motif consisting of a single-turn α-helix and a three-stranded antiparallel β-sheet, stabilized by four disulfide bridges. Vm24-toxin TFA attenuates the CD4+ effector memory T cell response to T cell receptor (TCR) stimulation.

N-Bromoacetamide
0 ImagesN-Bromoacetamide is an ion channel modulator that modifies proteins by cleaving peptide bonds. N-Bromoacetamide prolongs sodium channel opening time, increases Na+ influx, and eliminates fast inactivation of voltage-gated Na+ channels. N-Bromoacetamide irreversibly eliminates the calcium-dependent component of calcium-activated potassium channel opening and reduces channel open probability. N-Bromoacetamide slows the inactivation of inactivating K+ currents. N-Bromoacetamide also exhibits anti-enterovirus 71 (EV71) activity, inhibiting EV71 replication, reducing viral yield, and alleviating EV71-induced cytopathic effects. N-Bromoacetamide can be used in research on enterovirus infection.
