Ity to reduce tau phosphorylation and to restore the altered morphology of PC12 cells. Hence, this nootropic dipeptide is capable to positively impact not just popular pathogenic pathways but additionally disease-specific mechanisms underlying A-related pathology.

Journal of Biomedical Science 2014, 21:74 http:jbiomedscicontent211Page two ofBackground Alzheimer’s disease (AD) is the most common type of neurodegenerative disease, accompanied by age-related dementia, affecting 27 million people worldwide [1]. Mechanisms underlying the progression of late-onset AD consist of a variety of interacting events like excessive accumulation of amyloid, aberrant tau-protein phosphorylation, oxidative tension, chronic inflammatory circumstances, excitotoxicity, disruption of neurotrophine signaling, impairments in cytoskeleton stability and axonal transport, Envelope glycoprotein gp120 Protein custom synthesis synaptic and neuronal loss [2]. Pharmacological remedy of AD currently requires cholinesterase inhibitors and NMDA receptor antagonists. Unfortunately, in line with most investigators therapeutics of both these groups give mainly symptomatic advantages without counteracting the progression in the disease [3]. Drug analysis in the last decade has attempted to create disease-modifying drugs hopefully in a position to delay the onset or counteract the progression of AD. Approaches targeting at A pathology include decreasing of A production, preventing aggregation of A into amyloid plaques, stimulating IL-3 Protein Storage & Stability clearance of A. Neither inhibitors of -secretase or -secretase, nor stimulators of -secretase have demonstrated satisfactory potency combined with low toxicity. Drugs targeting tau-protein are recognized to become divided into various groups: modulators of tau phosphorylation, inhibitors of tau-phosphorylating kinases (e.g. glycogen-synthase-kinase-3, cyclin-dependent kinase-5, p70-S6-kinase) and compounds that prevent tau aggregation and misfolding [4]. AD is a complicated multifactorial pathology, which includes numerous cycles and subcycles of self-amplifying neurodegenerative method [5,6]. Monotherapy targeting single methods within this difficult cascade could explain disappointments in trials with agents affecting only 1 chain of this “circulus vituosus”. So it would be advantageous to explore the possibilities of novel multi-target therapy, aimed to affect various disease-related mechanisms, resulting in additive or synergic therapeutic responses [7]. Neuropeptides have drawn unique focus as potential multitarget drugs because of their high biological activity (a number of orders higher than that of nonpeptide ones), availability of several recognising internet sites supposed to be complimentary to several targets, the a.
