A series of thiosemicarbazone (TSC) p-substituted acetophenone derivatives were synthesized and chemically characterized. The p-substituents appended to the phenyl group of the TSC structures were hydrogen, fluor, chlorine, methyl, and nitro, producing compounds named TSC-H, TSC-F, TSC-Cl, TSC-Me,
The present paper evaluated the effect of the potential beta-adrenoreceptor blocker 2-(3-isopropylamino-2-hydroxypropoxy)-5-(propoxymethyl) acetophenone (FoA33) on the oxidative and phosphorylating processes of the cardiac muscle influenced by small doses of isoprenaline (2 mg.kg-1). Under selected
Mast cells (MCs), a type of immune effector cell, have recently become recognized for their ability to cause vascular leakage during dengue virus (DENV) infection. Although MC stabilizers have been reported to attenuate DENV induced infection in animal studies, there are limited in vitro
The root of Cynanchum wilfordii (C. wilfordii) contains several biologically active compounds which have been used as traditional medicines in Asia. In the present study, we evaluated the anti-inflammatory effects of an ethanol root extract of C. wilfordii (CWE) on tumor necrosis factor
The potential involvement of reactive oxygen species in the expression of genes involved in immune response was examined in mesangial cells. Tumor necrosis factor (TNF-alpha) and aggregated (aggr.) IgG increased mRNA levels for the monocyte chemoattractant protein, JE/MCP-1, and the
Searching for leading compounds of new drugs for cancer therapy, we studied the toxicity of 13 hydroxychalcones never tested before toward melanoma cell line (B16-F10). The compounds were obtained by aldolic condensation between aldehydes and hydroxylated acetophenones, in alkaline conditions. Three
(E)-3-(3-methoxyphenyl)-1-(2-pyrrolyl)-2-propenone (MPP) is an aldol condensation product resulting from pyrrole-2-carbaldehyde and m- and p- substituted acetophenones. However, its biological activity has not yet been evaluated. Since it has been reported that some propenone-type compounds display
Cardiopulmonary bypass (CPB) causes acute lung injury. Reactive oxygen species (ROS) from NADPH oxidase may contribute to this injury. To determine the role of NADPH oxidase, we pretreated pigs with structurally dissimilar NADPH oxidase inhibitors. Low-dose apocynin
Recent studies have shown that oligomeric amyloid-β (oAβ) peptide can potentially activate microglia in addition to inducing more potent neurotoxicity compared with fibrillar Aβ (fAβ); however, its mechanisms of action remain unclear. This study was designed to investigate the possible mechanisms
Breast cancer is the second cause of cancer‑related deaths in woman and the incidence of the disease has increased worldwide, in part due to improvements in early detection. Several drugs with anticancer effects have been extracted from plants in the last 20 years, many of which are particularly
OBJECTIVE
Previously, we have synthesized and characterized a novel Cu(II) complex, copper N-(2-hydroxy acetophenone) glycinate (CuNG). Herein, we have determined the efficacy of CuNG in overcoming multidrug-resistant cancer using drug-resistant murine and human cancer cell lines.
METHODS
Action of
Chemokines and adhesion molecules play a pivotal role in leukocyte infiltration during tissue injury. RANTES (regulated upon activation, normal T cell expressed and secreted) is a monocyte chemoattractant that induces the expression of CD11/CD18 integrins on leukocytes for which intercellular
tHGA, a geranyl acetophenone compound originally isolated from a local shrub called Melicope ptelefolia, has been previously reported to prevent ovalbumin-induced allergic airway inflammation in a murine model of allergic asthma by targeting cysteinyl leukotriene synthesis. Mast cells are immune
