PDE1 and Vinpocetine
Cheung (1970), Kakiuchi and Yamazaki (1970)
simultaneously discovered PDE1 from bovine and rat
brains, respectively, a calciprotein constituted of 148
aa, as a thermostable factor named calcium-
dependent activator or regulator (CDA or CDR) or
phosphodiesterase activating factor (PAF), which
binds 4 Ca 2+ mol/mol. This protein, named
calmodulin (CaM), was shown to activate cyclic
nucleotide phosphodiesterase in a calcium-dependent
manner. This discovery allowed characterizing the
first eluted fraction of PDE activity (Peak 1 or PDE I)
isolated by chromatography from vascular smooth
muscle. Since this PDE I fraction was specifically
activated by Ca2+/CaM, it was also named CaM-
PDE[11].
PDE1 family having three subtypes: PDE1A, PDE1B
and PDE1C and these PDE are stimulated by the
Ca 2+ -CAM. These enzymes catalyze the hydrolysis of
the cAMP and cGMP and were detected in: blood
vessels, heart, lung, testes, platelets and lymphocytes.
Vinpocetine is a PDE1 inhibitor which inhibit
Ca +2 /calmodulin-dependent phosphodiesterase (PDE)
type 1. Beside this, like vitamin E, vinpocetine is an
effective scavenger of hydroxyl radicals and shown
to inhibit lipid peroxidation in synaptosomes of
murine brain tissue and to protect against global
anoxia and hypoxia in animals.
Vinpocetine has been shown to protect neurons from
the toxicity of glutamate and Nmethyl-d-aspartate
(NMDA), lowers blood viscosity in patients with
cerebrovascular disease, has significant vasodilating
properties, decreases platelet aggregation, and
increasesand maintains erythrocyte flexibility
underoxidative stress[12].Vinpocetine iseffective in
ameliorating i.c.v. streptozotocin induced behavioural
alterations,cholinergic dysfunction and oxidative–
nitritive stress. Theobserved beneficial effects of
vinpocetine in spatialmemory processingmay be due
to its ability to restore cholinergic functions, prevent
neuronaldamage and possibly through its antioxidant
mechanism [13].
