Therapeutic drug monitoring (TDM), which involves measurement of drug or active metabolite levels and anti-drug antibodies, is a promising strategy that can be used to optimize inflammatory bowel disease therapeutics. It is based on the premise that there is a relationship between drug exposure and outcomes, and that considerable inter-individual variability exists in how patients metabolize the drug (pharmacokinetics) and the magnitude and duration of response to therapy (pharmacodynamics). Therefore, the American Gastroenterological Association has prioritized clinical guidelines on the role of TDM in the management of inflammatory bowel disease...

PURPOSE OF REVIEW: Unregulated uptake of oxidized LDL by macrophages to form foam cells is the hallmark for atherosclerosis. The paraoxonase (PON) family of enzymes plays a critical role in attenuating atherosclerotic lesion formation by hydrolyzing lipid peroxides (LOOHs) and preventing the oxidation of LDL particles and by enhancing HDL-mediated cholesterol efflux. Findings in recent years suggest novel mechanisms by which PON isoforms interact with macrophages to regulate cholesterol metabolism and cellular function...

The anti-malarial drug artesunate (ARS) has been shown to possess anti-inflammatory activity. Its effect on autoimmune hepatitis remains unclear. Concanavalin A (Con A)-induced hepatitis was used in this study to reveal the potential action of ARS and the related mechanism. Mice were pretreated with ARS followed by Con A challenge. Con A caused obvious hepatic injury with higher levels of liver enzymes, elevated pro-inflammatory cytokines and activation of nuclear factor-κB (NF-κB) and mitogen activated protein kinase (MAPK) signaling pathways...

One of the important strategies for the treatment of cancer is gene therapy which has the potential to exclusively eradicate malignant cells, without any damage to the normal tissues. Gene-directed enzyme prodrug therapy (GDEPT) is a two-step gene therapy approach, where a suicide gene is directed to tumor cells. The gene encodes an enzyme that expressed intracellularly where it is able to convert a prodrug into cytotoxic metabolites. Various delivery systems have been developed to achieve the appropriate levels of tumor restricted expression of chemotherapeutic drugs...

Left ventricular (LV) remodeling after myocardial infarction (MI) causes heart failure. Although medical therapies including angiotensin converting enzyme inhibitors show inhibitory effects on post-infarct LV remodeling, the prognosis of patients with post-infarct heart failure is still poor. Accumulating evidence suggests that an inflammatory response is implicated in the process of post-infarct LV remodeling. Therefore, we hypothesized that anti-inflammatory therapy by nanoparticle-mediated monocyte/macrophage-targeting delivery of pitavastatin may protect the heart from post-infarct LV remodeling...

AIMS: 5-lipoxygenase (5-LO) is the key enzyme of leukotriene biosynthesis and is critically involved in a number of inflammatory diseases such as arthritis, gout, bronchial asthma, atherosclerosis and cancer. Because 5-LO contains critical nucleophilic amino acids, which are sensitive to electrophilic modifications, we determined the consequences of a drug-mediated intracellular release of nitric oxide (NO) on 5-LO product formation by human granulocytes and on 5-LO-dependent pulmonary inflammation in vivo...

Cardiovascular disease (CVD) is a major problem during rheumatoid arthritis which leads to morbidity and mortality in arthritic patients. So the present study emphasizes combinatorial effect of Betulinic acid, a triterpenoid and fluvastatin, an HMG CoA reductase inhibitor on atherogenesis during arthritis. Arthritis was induced by bovine type II collagen dissolved in 0.01M acetic acid at a concentration of 4mg/mL and emulsified in equal volume of incomplete Freund's adjuvant. Betulinic acid (2mg/kg) and fluvastatin (5mg/kg) alone and in combination was administered orally from day 14 to 60...

Inflammatory bowel disease (IBD) is idiopathic, lifelong, immune-mediated diseases, for which curative therapies are not yet available. In the last 15 years, the introduction of monoclonal antibodies targeting tumor necrosis factor-α, a cytokine playing a key role in bowel inflammation, has revolutionized treatment paradigms for IBD. Despite their proven long-term efficacy, however, many patients do not respond or progressively lose response to these drugs. Major advances of knowledge in immunology and pathophysiology of intestinal inflammatory processes have made possible the identification of new molecular targets for drugs, thus opening several new potential therapeutic opportunities for IBD...

BACKGROUND: Therapeutic hypothermia (HT) in severe septic shock is associated with prolonged survival. We hypothesized that moderate HT would prolong survival and modulate the inflammatory response in rats with septic shock by exerting its therapeutic effect on splenic leukocytes. MATERIALS AND METHODS: Severe septic shock was created in rats by cecal ligation and incision (CLI). One hour after CLI or laparotomy, rats were randomized to sham, normothermia (NT), or 4 h of HT followed by 2 h of rewarming...

Curcumin, a component of a spice native to India, was first isolated in 1815 by Vogel and Pelletier from the rhizomes of Curcuma longa (turmeric) and, subsequently, the chemical structure of curcumin as diferuloylmethane was reported by Milobedzka et al. [(1910) 43., 2163-2170]. Since then, this polyphenol has been shown to exhibit antioxidant, anti-inflammatory, anticancer, antiviral, antibacterial, and antifungal activities. The current review primarily focuses on the anticancer potential of curcumin through the modulation of multiple cell signaling pathways...

Oxidative-stress induces inflammatory diseases. Further, infections caused by drug-resistant microbial strains are on the rise. This necessitates the discovery of novel small-molecules for intervention therapy. A series of 3-(2,3-dichlorophenyl)-1-(aryl)prop-2-en-1-ones are synthesized as intermediates via Claisen-Schmidt reaction approach. Subsequently, these intermediates were transformed into 2-pyrazolines by their reaction with phenylhydrazine hydrochlorides in methanol and few drops of acetic acid under reflux conditions...

Chronic inflammation is a well-known precursor for cancer development and proliferation. We have recently demonstrated that high salt (NaCl) synergizes with sub-effective interleukin (IL)-17 to induce breast cancer cell proliferation. However, the exact molecular mechanisms mediating this effect are unclear. In our current study, we adopted a phosphoproteomic-based approach to identify salt modulated kinase-proteome specific molecular targets. The phosphoprotemics based binary comparison between heavy labelled MCF-7 cells treated with high salt (Δ0...

Hydrogen sulfide (H2S) has anti‑inflammatory and neuroprotective properties, particularly during pathological processes. Experimental cerebral malaria (ECM), which is caused by vascular leakage into the brain, is characterized by inflammation, neurological deficits and cerebral hemorrhage. The present study investigated the correlation between ECM genesis and the levels of H2S. The results indicated that the levels of H2S derived from the brain decreased over time following ECM infection, and that the low H2S bioavailability was partially caused by decreased expression of the H2S generating enzyme, cystathionine‑β‑synthase...
