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.

Cetiedil
0 ImagesCat. No.: HY-W751362CAS No.: 14176-10-4Cetiedil is a vasodilator and potassium channel blocker with anti-sickle cell and analgesic activities. Cetiedil increases cyclic adenosine monophosphate levels, relaxes vascular smooth muscle, and blocks the action of Bradykinin (HY-P0206). Cetiedil inhibits platelet aggregation, reduces plasma fibrinogen concentration and blood viscosity, suppresses sickling of sickle red blood cells and improves their filterability, and decreases irreversible sickle cells. Cetiedil binds to calmodulin, inhibits Ca2+-dependent potassium permeability of erythrocyte membranes, increases sodium permeability of erythrocytes, and regulates polymorphonuclear leukocyte function. Cetiedil can be used in research related to intermittent claudication, arteriosclerosis obliterans, diabetic arteriosclerosis, Raynaud's disease, angina pectoris, and sickle cell anemia.

(3S,5R)-Rosuvastatin
0 ImagesCat. No.: HY-17504DCAS No.: 1242184-42-4(3S,5R)-Rosuvastatin is the (3S,5R)-enantiomer of Rosuvastatin. Rosuvastatin is a competitive HMG-CoA reductase inhibitor with an IC50 of 11 nM. Rosuvastatin potently blocks human ether-a-go-go related gene (hERG) current with an IC50 of 195 nM. Rosuvastatin reduces the expression of the mature hERG and the interaction of heat shock protein 70 (Hsp70) with the hERG protein. Rosuvastatin is very effective in lowering low-density lipoprotein (LDL) cholesterol, triglycerides, and C-reactive protein levels.

Phrixotoxin 2 mediates voltage-dependent inhibition of Kv4.2 and Kv4.3 currents, and voltage-independent inhibition of Kv4.1 currents. Phrixotoxin 2 fails to inhibit A-type K+ currents in visceral dorsal root ganglion neurons. Phrixotoxin 2 induces contraction of non-pregnant uterine smooth muscle and triggers orofacial cold hyperalgesia in rats. Phrixotoxin 2 can distinguish the contribution of Kv4 subunits to A-type K+ currents in different subsets of sensory neurons. Phrixotoxin 2 can be used in research related to chronic pain and trigeminal neuropathic pain.
