Mitochondrial Deacetylase Sirt3 Reduces Vascular Dysfunction and Hypertension While Sirt3 Depletion in Essential Hypertension Is Linked to Vascular Inflammation and Oxidative Stress

Johan Auwerx

Rationale: Hypertension represents a major risk factor for stroke, myocardial infarction, and heart failure and affects 30% of the adult population. Mitochondrial dysfunction contributes to hypertension, but specific mechanisms are unclear. The mitochondri ...

Varying the metal to ethacrynic acid ratio in ruthenium(ii)/osmium(ii)-p-cymene conjugates

Paul Joseph Dyson, Catherine Marie Amélie Clavel, Mylène Soudani, Emilia Paunescu

Following the identification of a ruthenium(II)-arene complex with an ethacrynic acid-modified imidazole ligand, which inhibits glutathione transferase (GST) and is cytotoxic to chemo-resistant cancer cells, a series of structurally related ruthenium(II)- ...

Organometallic Glutathione S-Transferase Inhibitors

Paul Joseph Dyson, Rosario Scopelliti, Emilia Paunescu, Mylène Soudani

A new family of organometallic p-cymene ruthenium(II) and osmium(II) complexes conjugated to ethacrynic acid, a glutathione transferase (GST) inhibitor, is reported. The ethacrynic acid moiety (either one or two) is tethered to the arene ruthenium(II) and ...

Arene Osmium Complexes with Ethacrynic Acid-Modified Ligands: Synthesis, Characterization, and Evaluation of Intracellular Glutathione S-Transferase Inhibition and Antiproliferative Activity

Paul Joseph Dyson, Tina Riedel, Emilia Paunescu

Four arene osmium complexes were prepared containing derivatives of ethacrynic acid, a potent inhibitor of glutathione Stransferases, either by direct coordination or via N- or P-donor ligands. The complexes were characterized by spectroscopic and analytic ...

The Effect of Valsartan versus Non-RAAS Treatment on Autoregulation of Cerebral Blood Flow

Jean-Marc Vesin

Background: Cerebral autoregulation (CA) is a protective mechanism which maintains the steadiness of the cerebral blood flow (CBF) through a broad range of systemic blood pressure (BP). Acute hypertension has been shown to reduce the cerebrovascular adapta ...

Targeting the ANG2/TIE2 axis inhibits tumor growth and metastasis by impairing angiogenesis and disabling rebounds of proangiogenic myeloid cells

Michele De Palma, Ferdinando Pucci

Tumor-infiltrating myeloid cells convey proangiogenic programs that counteract the efficacy of antiangiogenic therapy. Here, we show that blocking angiopoietin-2 (ANG2), a TIE2 ligand and angiogenic factor expressed by activated endothelial cells (ECs), re ...
