The triad indole-3-acetic acid ethyl ester/esterase/horseradish peroxidase as a new cytotoxic prodrug/enzyme combination
(Applied Cancer Research, 2010) [Artigo]
The antibody-directed enzyme prodrug therapy (ADEPT) is a means of restricting the action of toxic drugs to the tumor site. The enzyme/prodrug pair horseradish peroxidase (HRP)/indole-3-acetic acid (IAA) has been studied ...
Serum myeloperoxidase level is Increased in heavy smokers
(Open Journal of Clinical Diagnostics, 2013) [Artigo]
Raised myeloperoxidase (MPO) serum levels are associated with endothelial dysfunction and cigarette smoking is a risk factor for cardiovascular diseases. Since myocardial infarction is associated with leukocytosis and ...
Alkyl caffeates as anti-helicobacter pylori and scavenger of oxidants produced by neutrophils
(Medicinal Chemistry, 2014-02-01) [Artigo]
Helicobacter pylori pathogenic action involves the colonization of the gastrointestinal tract and a large production of reactive oxygen species (ROS) by the neutrophils attracted to the site of infection. The aim of this ...
Caffeic Acid Phenethyl Ester: Consequences of Its Hydrophobicity in the Oxidative Functions and Cytokine Release by Leukocytes
(Evidence-based Complementary And Alternative Medicine, 2014-01-01) [Artigo]
Numerous anti-inflammatory properties have been attributed to caffeic acid phenethyl ester (CAPE), an active component of propolis. NADPH oxidases are multienzymatic complexes involved in many inflammatory diseases. Here, ...
Effects of oxidation of lysozyme by hypohalous acids and haloamines on enzymatic activity and aggregation
(Biochimica et Biophysica Acta: Proteins and Proteomics, 2012-10-01) [Artigo]
Hen egg white lysozyme (HEL), an antibacterial enzyme, is a prototype protein for studying the physical and chemical events that underlie the formation of amyloid fibril aggregates. Here, we studied alterations in enzymatic ...
The co-catalytic effect of chlorpromazine on peroxidase-mediated oxidation of melatonin: enhanced production of N-1-acetyl-N (2)-formyl-5-methoxykynuramine
(Journal of Pineal Research, 2008-03-01) [Artigo]
Accumulating evidence points to relationships between increased production of reactive oxygen or decreased antioxidant protection in schizophrenic patients. Chlorpromazine (CPZ), which remains a benchmark treatment for ...
Inhibition of Lysozyme by Taurine Dibromamine
(Protein and Peptide Letters, 2013-11-01) [Artigo]
Hypobromous acid (HOBr) is a powerful oxidant produced by stimulated neutrophils and eosinophils. Taurine, a non-protein amino acid present in high amounts in the leukocytes, reacts instantaneously with HOBr leading to ...
Investigation of Human Albumin-Induced Circular Dichroism in Dansylglycine
(PLOS ONE, 2013-10-16) [Artigo]
Induced circular dichroism (ICD), or induced chirality, is a phenomenon caused by the fixation of an achiral substance inside a chiral microenvironment, such as the hydrophobic cavities in proteins. Dansylglycine belongs ...
Chemiluminescent determination of leukocyte alkaline phosphatase: An advantageous alternative to the cytochemical assay
(Journal of Clinical Laboratory Analysis, 2007-01-01) [Artigo]
The determination of leukocyte alkaline phosphatasd (LAP) is used as an aid to diagnose many diseases in the laboratory. For example, it can be used to distinguish chronic myeloid leukemia (CML) from other myeloproliferative ...
Oxidation of acetylacetone catalyzed by horseradish peroxidase in the absence of hydrogen peroxide
(Biochimica et Biophysica Acta: General Subjects, 2006-12-01) [Artigo]
Horseradish peroxidase (HRP) is a plant enzyme widely used in biotechnology, including antibody-directed enzyme prodrug therapy (ADEPT). Here, we showed that HRP is able to catalyze the autoxidation of acetylacetone in the ...
