Calmodulin Antagonist

Calmodulin Antagonists (12):

Cat. No. Product Name Effect Purity
  • HY-103319
    Calmidazolium chloride
    		Antagonist 99.69%
    Calmidazolium chloride (R 24571) is a calmodulin antagonist, antagonizing CaM-dependent phosphodiesterase and calmodulin-induced activation of erythrocyte Ca2+-transporting ATPase with IC50s of 0.15 and 0.35 μM, respectively. Also in anti-cancer research. Calmidazolium binds to calmodulin with a Kd of 3 nM.
  • HY-100912
    W-7 hydrochloride
    		Antagonist 99.65%
    W-7 hydrochloride is a selective calmodulin antagonist. W-7 hydrochloride inhibits the Ca2+-calmodulin-dependent phosphodiesterase and myosin light chain kinase with IC50 values of 28 μM and 51 µM, respectively. W-7 hydrochloride induces apoptosis and has antitumor activity.
  • HY-125412
    Fasciculic acid B
    		Antagonist
    Fasciculic acid B is a steroid that can be isolated from Hypholoma lateritium. Fasciculic acid B has antiinflammatory and calmodulin antagonistic activity.
  • HY-N7733
    Fasciculic acid A
    		Antagonist
    Fasciculic acid A is a steroid that can be isolated from Hypholoma lateritium. Fasciculic acid B has antiinflammatory and calmodulin antagonistic activity.
  • HY-P1076A
    CALP2 TFA
    		Antagonist 98.48%
    CALP2 TFA is a calmodulin (CaM) antagonist (Kd of 7.9 µM) with high affinity for binding to the CaM EF-hand/Ca2+-binding site. CALP2 TFA inhibits CaM-dependent phosphodiesterase activity and increases intracellular Ca2+ concentrations. CALP2 TFA potently inhibits of adhesion and degranulation. CALP2 TFA is also a strong activator of alveolar macrophages.
  • HY-100913
    W-7 isomer hydrochloride
    		Antagonist 99.50%
    W-7 isomer hydrochloride is an isomer of W-7 hydrochloride (HY-100912). W-7 hydrochloride is a selective calmodulin antagonist.
  • HY-105118A
    Zaldaride maleate
    		Antagonist ≥98.0%
    Zaldaride maleate (CGS-9343B) is a potent, orally active and selective inhibitor of calmodulin. Zaldaride maleate (CGS-9343B) inhibits CaM (calmodulin)-stimulated cAMP phosphodiesterase activity, with an IC50 of 3.3 nM. Zaldaride maleate (CGS-9343B) prevents estrogen-induced transcription activation by ER, reversibly blocks voltage-activated Na+, Ca2+ and K+ currents in PC12 cells and inhibits nAChR.
  • HY-115745
    Calmodulin antagonist-1
    		Antagonist ≥98.0%
    Calmodulin antagonist-1 (A-5) is a calmodulin (CaM) antagonist. Calmodulin antagonist-1 inhibits calmodulin-activated Ca2+-phosphodiesterase (PDE) (IC50=66 μM). Calmodulin antagonist-1 also inhibits trypsin-treated Ca2+-PDE (IC50=560 μM) in a competitive fashion with respect to cyclic GMP.
  • HY-100914
    A-7 hydrochloride
    		Antagonist 99.09%
    A-7 hydrochloride (Ophobolin A) is a calmodulin antagonist and can be used for the research of cancer.
  • HY-P1076
    CALP2
    		Antagonist
    CALP2 is a calmodulin (CaM) antagonist ( (Kd of 7.9 µM)) with high affinity for binding to the CaM EF-hand/Ca2+-binding site. CALP2 inhibits CaM-dependent phosphodiesterase activity and increases intracellular Ca2+ concentrations. CALP2 potently inhibits of adhesion and degranulation. CALP2 is also a strong activator of alveolar macrophages.
  • HY-133782
    Fluphenazine-N-2-chloroethane hydrochloride
    		Antagonist
    Fluphenazine-N-2-chloroethane (SKF-7171A) hydrochloride is a potent irreversiblecalmodulin antagonist.
  • HY-19025
    CV-159
    		Antagonist
    CV-159 is a unique dihydropyridine Ca2+ antagonist with an anti-calmodulin (CaM) action, and has antiinflammatory activities.
