General description

Methoxyverapamil is a calmodulin antagonist. It controls flagellar glycoprotein redistribution by modulating calcium signalling. Methoxyverapamil impacts the effect of intracellular calcium levels and affects the sperm capacitation function.

Application

(±)-Methoxyverapamil hydrochloride has been used:
  • as calcium channel antagonist in Schistosoma mansoni parasite
  • as calcium entry blocker in cultured macrophages
  • in the inhibition of L-type voltage gated Ca2+-channels

Biochem/physiol Actions

Blocks L-type Ca2+ channels
