Canale del potassio
I canali del potassio sono un gruppo diversificato di proteine di membrana che facilitano il flusso di ioni potassio (K+) attraverso la membrana cellulare. Questi canali svolgono un ruolo cruciale nel mantenimento del potenziale di membrana a riposo, nella regolazione del volume cellulare e nel controllo dell'eccitabilità dei neuroni e delle cellule muscolari. I canali del potassio sono coinvolti in vari processi fisiologici, tra cui la regolazione del ritmo cardiaco, la secrezione di insulina e il rilascio di neurotrasmettitori. La disfunzione dei canali del potassio è legata a condizioni come aritmie, epilessia e ipertensione. Presso CymitQuimica, offriamo una vasta gamma di modulatori dei canali del potassio per supportare la tua ricerca in elettrofisiologia, salute cardiovascolare e neurobiologia.

MASP-2-IN-1 (Compound 77) is an inhibitor of mannan-binding lectin-associated serine proteases (MASP), specifically targeting MASP2 and MASP3, with IC50 values of 11.4 nM and 13.2 µM, respectively. It shows weak inhibitory activity on hERG with an IC50 of 175 µM. This compound exhibits poor stability in mouse plasma, with a half-life of 4.4 hours.Formula:C22H21N7O3SColore e forma:SolidPeso molecolare:463.512Lei-Dab7
CAS:Selective KCa2.2 channel blocker with Kd 3.8 nM, >200-fold specificity, enhances LTP, convulsive in vivo.Formula:C141H236N46O39S6Purezza:98%Colore e forma:SolidPeso molecolare:3392.06GsAF-II
GsAF-II is a peptide toxin that selectively blocks hERG1 subtype potassium channels through a voltage-dependent mechanism and impedes Nav1.x subtype sodiumFormula:C176H261N47O45S7Purezza:98%Colore e forma:SolidPeso molecolare:3979.7Heteropodatoxin-1
<p>Heteropodatoxin-1 (HpTx1), a spider peptide toxin, acts as an inhibitor of the Kv4.2 current, while concurrently inhibiting Nav1.7 and activating Nav1.9</p>Formula:C168H238N46O51S6Purezza:98%Colore e forma:SolidPeso molecolare:3910.35AmmTX3
KV4 channel blocker that inhibits A-type K+ current in mouse neurons; requires DPP6 and DPP10 for effect.Formula:C158H262N50O48S6Purezza:98%Colore e forma:SolidPeso molecolare:3822.47Ebio3
Ebio3 is a selective potassium ion channel (KCNQ2) inhibitor with an IC50 of 1.2 nM. It binds to the KCNQ2 channel via its hydrophobic tail, causing the inward movement of the S6 helix, which results in the closure of the internal gate. The inhibitory effect of Ebio3 is equally effective on pathogenic KCNQ2 mutants, such as R75C and I238L, reducing their outward current by approximately 80%. Ebio3 holds potential for research in neurological disorders like epilepsy.Formula:C19H23F2N3O2Colore e forma:SolidPeso molecolare:363.4Dendrotoxin K
