Abstract

Novel therapeutic approaches for the treatment of neurodegenerative disorders comprise drug candidates designed specifically to act on multiple CNS targets. We have synthesized a multifunctional non‐toxic, brain permeable iron chelator drug, M‐30, possessing propargyl monoamine oxidase (MAO) inhibitory neuroprotective and iron‐chelating moieties, from our prototype iron chelator VK‐28. In the present study M‐30 was shown to possess a wide range of pharmacological activities, including pro‐survival neurorescue effects, induction of neuronal differentiation and regulation of amyloid precursor protein (APP) and β‐amyloid (Aβ) levels. M‐30 was found to decrease apoptosis of SH‐SY5Y neuroblastoma cells in a neurorescue, serum deprivation model, via reduction of the pro‐apoptotic proteins Bad and Bax, and inhibition of the apoptosis‐associated phosphorylated H2A.X protein (Ser 139) and caspase 3 activation. In addition, M‐30 induced the outgrowth of neurites, triggered cell cycle arrest in G 0/G 1 phase and enhanced the expression of growth associated protein‐43. Furthermore, M‐30 markedly reduced the levels of cellular APP and β‐C‐terminal fragment (β‐CTF) and the levels of the amyloidogenic Aβ peptide in the medium of SH‐SY5Y cells and Chinese hamster ovary cells stably transfected with the APP ‘Swedish’ mutation. Levels of the non‐amyloidogenic soluble APPα and α‐CTF in the medium and cell lysate respectively were coordinately increased. These properties, together with its brain selective MAO inhibitory and propargylamine‐ dependent neuroprotective effects, suggest that M‐30 might serve as an ideal drug for neurodegenerative disorders, such as Parkinson's and Alzheimer's diseases, in which oxidative stress and iron dysregulation have been implicated.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
