    So these are comming and there is nothing yet on the web page. How do you know that these are comming? Could you explain a bit more, please.

  • While waiting PBT434 studies, it good to read this, hope it is not posted earlier.

    Reactivity of copper-α-synuclein peptide complexes relevant to Parkinson's disease.

    Dell'Acqua S1, Pirota V, Anzani C, Rocco MM, Nicolis S, Valensin D, Monzani E, Casella L.

    Parkinson's disease (PD) is a neurodegenerative disorder characterized by the presence of abnormal α-synuclein (αSyn) deposits in the brain. Alterations in metal homeostasis and metal-induced oxidative stress may play a crucial role in the aggregation of αSyn and, consequently, in the pathogenesis of PD. We have therefore investigated the capability of copper-αSyn6 and copper-αSyn15 peptide complexes, with the 1-6 and 1-15 terminal fragments of the protein, to promote redox reactions that can be harmful to other cellular components. The pseudo-tyrosinase activity of copper-αSyn complexes against catecholic (di-tert-butylcatechol (DTBCH2), 4-methylcatechol (4-MC)) and phenolic (phenol) substrates is lower compared to that of free copper(ii). In particular, the rates (kcat) of DTBCH2 catalytic oxidation are 0.030 s(-1) and 0.009 s(-1) for the reaction promoted by free copper(ii) and [Cu(2+)-αSyn15], respectively. On the other hand, HPLC/ESI-MS analysis of solutions of αSyn15 incubated with copper(ii) and 4-MC showed that αSyn is competitively oxidized with remarkable formation of sulfoxide at Met1 and Met5 residues. Moreover, the sulfoxidation of methionine residues, which is related to the aggregation of αSyn, also occurs on peptides not directly bound to copper, indicating that external αSyn can also be oxidized by copper. Therefore, this study strengthens the hypothesis that copper plays an important role in oxidative damage of αSyn which is proposed to be strongly related to the etiology of PD.

  • This paper is already one month old and may be it was discussed here. It is a free paper and worth reading it again. Go and find it in pubmed.

    Evidence that Human Prostate Cancer is a ZIP1-Deficient Malignancy that could be Effectively Treated with a Zinc Ionophore (Clioquinol) Approach.

    Despite decades of research, no efficacious chemotherapy exists for the treatment of prostate cancer. Malignant prostate zinc levels are markedly decreased in all cases of prostate cancer compared to normal/benign prostate. ZIP1 zinc transporter down regulation decreases zinc to prevent its cytotoxic effects. Thus, prostate cancer is a "ZIP1-deficient" malignancy. A zinc ionophore (e.g. Clioquinol) treatment to increase malignant zinc levels is a plausible treatment of prostate cancer. However, skepticism within the clinical/biomedical research community impedes significant progress leading to such a zinc treatment. This report reviews the clinical and experimental background, and presents new experimental data showing Clioquinol suppression of prostate malignancy; which provides strong support for a zinc ionophore treatment for prostate cancer. Evaluation of often-raised opposing issues is presented. These considerations lead to the conclusion that the compelling evidence dictates that a zinc-treatment approach for prostate cancer should be pursued with additional research leading to clinical trials.

    eso, that has been my opinion for a long time. Orphan status and these facts are the most important issues IMO but it looks like something more is needed to get conditional approval.
