Topical Erythropoietin Accelerates Wound Closure in Patients with Diabetic Foot Ulcers: A Prospective, Multicenter, Single-Blind, Randomized, Controlled Trial.

The diabetic foot ulcer (DFU) is a major disabling complication of diabetes mellitus. Growing evidence suggests that topical erythropoietin (EPO) can promote wound healing. The aim of this study is to clinically assess the efficacy of a proprietary topical EPO-containing hydrogel for treating DFUs.

Topical Erythropoietin Treatment Accelerates the Healing of Cutaneous Burn Wounds in Diabetic Pigs Through an Aquaporin-3-Dependent Mechanism.

We have previously reported that the topical application of erythropoietin (EPO) to cutaneous wounds in rats and mice with experimentally induced diabetes accelerates their healing by stimulating angiogenesis, reepithelialization, and collagen deposition, and by suppressing the inflammatory response and apoptosis. Aquaporins (AQPs) are integral membrane proteins whose function is to regulate intracellular fluid hemostasis by enabling the transport of water and glycerol. AQP3 is the AQP that is expressed in the skin where it facilitates cell migration and proliferation and re-epithelialization during wound healing.

Neuroprotective and neurorestorative activities of a novel iron chelator-brain selective monoamine oxidase-A/monoamine oxidase-B inhibitor in animal models of Parkinson's disease and aging.

Recently, we have designed and synthesized a novel multipotent, brain-permeable iron-chelating drug, VAR10303 (VAR), possessing both propargyl and monoamine oxidase (MAO) inhibitory moieties. The present study was undertaken to determine the multiple pharmacological activities of VAR in neurodegenerative preclinical models. We demonstrate that VAR affords iron chelating/iron-induced lipid-peroxidation inhibitory potency and brain selective MAO-A and MAO-B inhibitory effects, with only limited tyramine-cardiovascular potentiation of blood pressure.
