Alternative Name: Zaldaride maleate

Chemical Name: 1,3-Dihydro-1-[1-[(4-methyl-4H,6H-pyrrolo[1,2-a][4,1]benzoxazepin-4-yl)methyl]-4-piperidinyl]-2H-benzimidazol-2-one maleate

Biological Activity

Calmodulin antagonist; inhibits calmodulin-stimulated cAMP phosphodiesterase activity with an IC50 of 3.3 nM. Also prevents estrogen-induced transcription activation by ER, reversibly blocks voltage-activated Na+, Ca2+ and K+ currents in PC12 cells and inhibits nAChR.

Technical Data

Soluble to 50 mM in DMSO and to 10 mM in ethanol with gentle warming
>98 %
Desiccate at RT
