Interleukin-1beta and prostaglandin-synthesizing enzymes as modulators of human omental and subcutaneous adipose tissue function

IL-1beta stimulates expression of prostaglandin (PG)-synthesizing enzymes cyclooxygenase (COX)-2 and aldo-keto reductase (AKR)1B1 in human preadipocytes. We aimed to examine the impact of IL-1beta COX-2 and AKR1B1 on markers of human visceral and subcutaneous adipose tissue function, and to assess whether PG synthesis by these enzymes mediates IL-1beta effects. Omental and subcutaneous fat samples were obtained from bariatric surgery patients. PG release and expression of inflammatory and adipogenic markers were assessed in explants treated with COX-2 inhibitor NS-398 or AKR1B1 inhibitor Statil, with or without IL-1beta. Preadipocyte differentiation experiments were also performed. IL-1beta decreased expression of PPARgamma in both fat depots compared to control and increased expression of NF-kappaB1, IL-6, CCL-5, ICAM-1 and VEGFA, especially in visceral fat for IL-6, CCL-5 and VEGFA. Adding Statil or NS-398 to IL-1beta blunted PGF2alpha and PGE2 release, but did not alter IL-1beta effects on adipose tissue function markers. IL-1beta down-regulated adipocyte differentiation whereas NS-398 alone increased this process. However, NS-398 did not prevent IL-1beta inhibition of adipogenesis. We conclude that IL-1beta induces a pro-inflammatory response in human adipose tissues, particularly in visceral fat, and acts independently of concomitant PG release. IL-1beta and COX-2 appear to be critical determinants of adipose tissue pathophysiologic remodeling in obesity.

Vitreous humor endogenous compounds analysis for post-mortem forensic investigation

The chemical and biochemical analysis of bodily fluids after death is an important thanatochemical approach to assess the cause and time since death. Vitreous humor (VH) has been used as a biofluid for forensic purposes since the 1960s. Due to its established relevance in toxicology, a literature review highlighting the use of VH with an emphasis on endogenous compounds has not yet been undertaken. VH is a chemically complex aqueous solution of carbohydrates, proteins, electrolytes and other small molecules present in living organisms; this biofluid is useful tool for its isolated environment, preserved from bacterial contamination, decomposition, autolysis, and metabolic reactions. The post-mortem analysis of VH provides an important tool for the estimation of the post-mortem interval (PMI), which can be helpful in determining the cause of death. Consequently, the present review evaluates the recent chemical and biochemical advances with particular importance on the endogenous compounds present at the time of death and their modification over time, which are valuable for the PMI prediction and to identify the cause of death.

PARP-1-targeted radiotherapy in mouse models of glioblastoma

The DNA repair enzyme poly(ADP-ribose) polymerase 1 (PARP-1) is overexpressed in glioblastoma, with overall low expression in healthy brain tissue. Paired with the availability of specific small molecule inhibitors, PARP-1 is a near-ideal target to develop novel radiotherapeutics to induce DNA damage and apoptosis in cancer cells, while sparing healthy brain tissue. Methods: We synthesized an 131I-labeled PARP-1 therapeutic and investigated its pharmacology in vitro and in vivo. A subcutaneous tumor model was used to quantify retention times and therapeutic efficacy. A potential clinical scenario, intratumoral convection-enhanced delivery, was mimicked using an orthotopic glioblastoma model combined with an implanted osmotic pump system to study local administration of 131I-PARPi (PARPi is PARP inhibitor). Results: 131IPARPi is a 1(2H)-phthalazinone, similar in structure to the Food and Drug Administration-approved PARP inhibitor AZD-2281. In vitro studies have shown that 131I-PARPi and AZD-2281 share similar pharmacologic profiles. 131I-PARPi delivered 134.1 cGy/ MBq intratumoral injected activity. Doses to nontarget tissues, including liver and kidney, were significantly lower. Radiation damage and cell death in treated tumors were shown by p53 activation in U87-MG cells transfected with a p53-bioluminescent reporter. Treated mice showed significantly longer survival than mice receiving vehicle (29 vs. 22 d, P , 0.005) in a subcutaneous model. Convection-enhanced delivery demonstrated efficient retention of 131I-PARPi in orthotopic brain tumors, while quickly clearing from healthy brain tissue. Conclusion: Our results demonstrate 131IPARPi’s high potential as a therapeutic and highlight PARP’s relevance as a target for radionuclide therapy. Radiation plays an integral role in brain tumor therapy, and radiolabeled PARP therapeutics could ultimately lead to improvements in the standard of care.

Synthesis, activity, and molecular modeling of new 2,4-dioxo-5- (naphthylmethylene)-3-thiazolidineacetic acids and 2-thioxo analogues as potent aldose reductase inhibitors

A series of 2,4-dioxo-5-(2-naphthylmethylene)-3-thiazolidineacetic acids and 2-thioxo analogues have been prepared as aldose reductase inhibitors. In vitro inhibitory activities of bovine lens aldose reductase were determined by a conventional method. 1-Naphthyl-substituted derivafives of the 2-thioxo series were the more potent inhibitors (IC50 ? 10 nM) with similar activity to that of Epalrestat. Structural analysis, especially by X-ray crystallography of two selected compounds, and molecular modeling comparisons with Zopolrestat were performed. These results provide explanations of the good activity of the inhibitor, the preference for 1-naphthyl-substituted compounds, and the nature of molecular interactions in these systems.

Identification of an aldose reductase inhibitor site by affinity labeling

Animal studies indicate that aldose reductase inhibitors represent a pharmacological method for inhibiting the onset of diabetic complications that is independent of blood sugar control. This has spurred the development of dose reductase inhibitors (ARIs). To facilitate the rational development of more potent and direct ARIs, more specific knowledge of the structural and pharmacophoric requirements of the site at which ARIs interact are required. Co-crystalization of human placental aldose reductase with the inhibitor zopolrestat has been reported to result in a complex where the inhibitor is almost completely sequestered in the hydrophobic pocket which forms the substrate site. Zopolrestat’s observed location, which makes the active site pocket inaccessible to solvent or further productive binding of substrate, is not supported by published inhibitor structure activity relationships (SAR) studies or kinetic results which indicate that aldose reductase inhibitors such as zopolrestat are either non-competitive or uncompetitive inhibitors. Using a 5-iodoacetamido analog of alrestatin as an affinity labeled aldose reductase inhibitor, an inhibitor binding site on aldose reductase has been located. This inhibitor binding site contains a number of pharmacophoric elements previously proposed for the inhibitor site. Its location and composition is consistent with reported kinetic data, SAR observations, stereochemical requirements, and quantum chemical calculations.

Synthesis and evaluation of a radioiodinated tracer with specificity for poly(ADP-ribose) polymerase-1 (PARP-1) in vivo

Interest in nuclear imaging of poly(ADP-ribose) polymerase-1 (PARP-1) has grown in recent years due to the ability of PARP-1 to act as a biomarker for glioblastoma and increased clinical use of PARP-1 inhibitors. This study reports the identification of a lead iodinated analog 5 of the clinical PARP-1 inhibitor olaparib as a potential single-photon emission computed tomography (SPECT) imaging agent. Compound 5 was shown to be a potent PARP-1 inhibitor in cell-free and cellular assays, and it exhibited mouse plasma stability but approximately 3-fold greater intrinsic clearance when compared to olaparib. An 123I-labeled version of 5 was generated using solid state halogen exchange methodology. Ex vivo biodistribution studies of [123I]5 in mice bearing subcutaneous glioblastoma xenografts revealed that the tracer had the ability to be retained in tumor tissue and bind to PARP-1 with specificity. These findings support further investigations of [123I]5 as a noninvasive PARP-1 SPECT imaging agent.

Flavones: An important scaffold for medicinal chemistry

Flavones have antioxidant, anti-proliferative, anti-tumor, anti-microbial, estrogenic, acetyl cholinesterase, anti-inflammatory activities and are also used in cancer, cardiovascular disease, neurodegenerative disorders, etc. Also, flavonoids are found to have an effect on several mammalian enzymes like protein kinases that regulate multiple cell signaling pathways and alterations in multiple cellular signaling pathways are frequently found in many diseases. Flavones have been an indispensable anchor for the development of new therapeutic agents. The majority of metabolic diseases are speculated to originate from oxidative stress, and it is therefore significant that recent studies have shown the positive effect of flavones on diseases related to oxidative stress. Due to the wide range of biological activities of flavones, their structure-activity relationships have generated interest among medicinal chemists. The outstanding development of flavones derivatives in diverse diseases in very short span of time proves its magnitude for medicinal chemistry research. The present review gives detail about the structural requirement of flavone derivatives for various pharmacological activities. This information may provide an opportunity to scientists of medicinal chemistry discipline to design selective, optimize as well as poly-functional flavone derivatives for the treatment of multi-factorial diseases.

Assorted applications of N-substituted-2,4-thiazolidinediones in various pathological conditions

Thiazolidine-2,4-dione (TZD) is one of the most frequently encountered heterocyclic rings which has been implicated in design and synthesis of entities for various pathogenic conditions including cancer. Since its discovery various substitutions at 5th position have been carried out and reviewed. Various substitutions at 5th position have led to generation of glitazones, whose target peroxisome proliferating activated receptor gamma (PPARgamma) was found decade after their discovery. Acidic hydrogen (-NH) of TZD is a prime pharmacophoric requirement for the activation of PPARgamma. However, advanced in-silico techniques have helped to design compounds bearing substitutions at both methylene and -NH group of TZD, targeting range of enzymes involved in various pathological conditions viz., diabetes, hyperlipidemia, infectious disease, inflammation and cancer. The promising activities shown by methylene and N-substituted TZDs in above mentioned therapeutic areas, prompted us to collate the information which would help researchers to alter the structure of existing ligands and to design new TZD derivatives with better safety and efficacy profiles.

Inhibition of aldose reductase and sorbitol accumulation by hydroalcoholic extract of propolis

Background: Increased polyol pathway activity and subsequent occurrences, and particular sorbitol accumulation are noticed in the development of various secondary complications of diabetes. Aldose reductase (ALR2) or aldo-ketoreductase (AKR1B1) as the first and rate limiting enzyme of this pathway is a good target for new drugs for diabetes complications. A good inhibitor should inhibit aldehyde reductase (ALR1), the other member of this family lesser than ALR2. Bee propolis is a known substance in ancient medicine, but its effect on polyol pathway is unknown. Objectives: The current study aimed to investigate the effect of hydroalcoholic extract of propolis (HAEP) on partial purified bovine lens ALR2, also the effect of HAEP on sorbitol accumulation in human erythrocytes in high-glucose condition (ex vivo). Materials and Methods: Total protein was determined by lowery method. Bovine lens ALR2 was partially purified by gel filtration chromatography on sephadexTM G25. Bovine cortex kidney ALR1 was partially purified by diethylaminoethyl (DEAE) precipitation. The hydroalcoholic extract was obtained from frozen propolis. The enzyme activity and sorbitol accumulation in erythrocytes were determined spectroflourimetrically. Results: It was found that ethyl acetate (EthAc) fraction (the more potent fraction) of HAEP inhibited ALR2 by IC50 value of 1.12 mg/mL up to 50% and this fraction can inhibit ALR2 8.25-fold greater than ALR1. In addition, it was found that this fraction could decrease sorbitol accumulation in human erythrocytes under high-glucose condition. Conclusions: The obtained results indicated that propolis may be a good candidate for more studies to find new drugs for the treatment of secondary complications of diabetes.
