Microwave assisted reactions of some azaheterocylic compounds

A fast, general, environmentally friendly and facile method for preparation of five- and six-membered ring diazaheterocylic salts under microwave irradiation is presented. The N-alkylation reactions of imidazole, pyrimidine, pyridazine and phthalazine have been studied. The microwaves remarkably accelerated these N-alkylations, the reaction times decreased dramatically, the reaction conditions were milder, the consumed energy decreased considerably and the amount of solvents used was reduced substantially. Consequently, the microwave assisted alkylation of N-containing heterocycles could be considered eco-friendly. In some cases, under MW irradiation the yields are also higher. A comparative study of microwave vs. classical conditions (liquid solvents) has been done. Twelve new diazaheterocylic salts of potential practical interest were obtained.

Diabetic neuropathy: Mechanisms to management

Neuropathy is the most common and debilitating complication of diabetes and results in pain, decreased motility, and amputation. Diabetic neuropathy encompasses a variety of forms whose impact ranges from discomfort to death. Hyperglycemia induces oxidative stress in diabetic neurons and results in activation of multiple biochemical pathways. These activated pathways are a major source of damage and are potential therapeutic targets in diabetic neuropathy. Though therapies are available to alleviate the symptoms of diabetic neuropathy, few options are available to eliminate the root causes. The immense physical, psychological, and economic cost of diabetic neuropathy underscore the need for causally targeted therapies. This review covers the pathology, epidemiology, biochemical pathways, and prevention of diabetic neuropathy, as well as discusses current symptomatic and causal therapies and novel approaches to identify therapeutic targets.

Synthesis and biological evaluation of 2,4-Diaminopyrimidine-based antifolate drugs against bacillus anthracis

Due to the innate ability of bacteria to develop resistance to available antibiotics, there is a critical need to develop new agents to treat more resilient strains. As a continuation of our research in this area, we have synthesized a series of racemic 2,4-diaminopyrimidine-based drug candidates, and evaluated them against Bacillus anthracis. The structures are comprised of a 2,4-diaminopyrimidine ring, a 3,4-dimethoxybenzyl ring, and an N-acryloyl-substituted 1,2-dihydrophthalazine ring. Various changes were made at the C1 stereocenter of the dihydrophthalazine moiety in the structure, and the biological activity was assessed by measurement of the MIC and Ki values to identify the most potent drug candidate.

Iron-catalyzed Minisci acylation of N-heteroarenes with alpha-keto acids

An efficient and mild protocol has been developed for the Minisci acylation reactions of nitrogen-containing heteroarenes with alpha-keto acids. Distinct from the conventional Minisci acylation conditions, the chemistry was performed using non-noble metal Fe(II), instead of expensive Ag(I) salt, as catalyst. A wide range of substrates, including aliphatic or aromatic alpha-keto acids, as well as various N-heteroarenes, proved to be compatible with the protocol. Scale-up experiment also demonstrates the practicality of the approach.

An 18F-Labeled Poly(ADP-ribose) Polymerase Positron Emission Tomography Imaging Agent

Poly(ADP-ribose) polymerase (PARP) is involved in repair of DNA breaks and is over-expressed in a wide variety of tumors, making PARP an attractive biomarker for positron emission tomography (PET) and single photon emission computed tomography imaging. Consequently, over the past decade, there has been a drive to develop nuclear imaging agents targeting PARP. Here, we report the discovery of a PET tracer that is based on the potent PARP inhibitor olaparib (1). Our lead PET tracer candidate, [18F]20, was synthesized and evaluated as a potential PARP PET radiotracer in mice bearing subcutaneous glioblastoma xenografts using ex vivo biodistribution and PET-magnetic resonance imaging techniques. Results showed that [18F]20 could be produced in a good radioactivity yield and exhibited specific PARP binding allowing visualization of tumors over-expressing PARP. [18F]20 is therefore a potential candidate radiotracer for in vivo PARP PET imaging.

Chemiluminescent immunoassay technology: what does it change in autoantibody detection?

Diagnostic technology is rapidly evolving, and over the last decade, substantial progress has been made even for the identification of antibodies, increasingly approaching this type of diagnostic to that of automated clinical chemistry laboratory. In this review, we describe the analytical and diagnostic characteristics of chemiluminescence technology in its strength and in its applicability for a more rapid and accurate diagnosis of autoimmune diseases. The wide dynamic range, greater than that of immunoenzymatic methods, the high sensitivity and specificity of the results expressed in quantitative form, the high degree of automation and the clinical implications related to the reduction in the turnaround time, and the ability to run a large number of antibody tests (even of different isotypes), directed towards large antigenic panels in random access mode, make this technology the most advanced in the clinical laboratory, with enormous repercussions on the workflow and on the autoimmunology laboratory organisation. Further improvements are expected in the coming years with the development of new analytical platforms such as the flow-injection chemiluminescent immunoassay, the two-dimensional resolution for chemiluminescence multiplex immunoassay and the magnetic nanoparticles chemiluminescence immunoassay, which will likely result in additional increases in the clinical efficacy of antibody tests.

In vitro effects of very low levels of aflatoxin B1 on free radicals production and bactericidal activity of bovine blood neutrophils

As one of the most potent and hazardous feed/food-originated mycotoxins, aflatoxin (AF) B1 is regarded as a potent immunosuppressor in dairy cows. Neutrophils (PMN), as key effector cells against pathogens, have a high potential to kill engulfed microbes. To investigate the in vitro effects of very low doses of AFB1 on blood PMN functions, we examined the effects of biologically relevant concentrations of AFB1 on the phagocytosis and non-phagocytosis dependent luminol, representative of mainly intracellular free radicals, and isoluminol, representative of mainly extracellular free radicals, chemiluminescence (CL), necrosis and apoptosis of PMN. Isolated blood PMN from healthy dairy cows (n=12) were exposed to 0, 0.01, 0.05 and 0.5ng/ml of AFB1 for 0.5 and 18h depending on the assay. Further, blood PMN of healthy dairy cows (n=8) were exposed to 0.5ng/ml of AFB1 for 3h and myeloperoxidase (MPO) activity, superoxide anion (O2-) production, phagocytosis and killing activities against Staphylococcus (S.) aureus and Escherichia (E.) coli, were examined. Though the effect of extremely low doses of AFB1 were less pronounced, at 0.5ng/ml the production of free radicals was greatly enhanced, especially extracellularly. In contrast to isoluminol CL, the AFB1-treated PMN showed a remarkably impaired phagocytosis-depended luminol CL. PMN necrosis and apoptosis were not affected by AFB1. MPO activity, O2- production, phagocytosis rates and killing of E. coli and S. aureus by AFB1-treated PMN were significantly lower than those of non-treated ones. Our results show the extracellularly pro-oxidant and antiphagocytic properties of very low doses of AFB1 for bovine PMN. The scope of the suppressive effects of the in vitro AFB1 levels on cellular innate immune functions should be considered for high yielding dairy cows.

Though several detailed examples have been discussed, the list is by no means exhaustive as can be seen from the many systems that have been briefly mentioned. It will be seen in Chapter 7 that only a few systems have stood the test of time and have gained acceptance as methods that can be applied to routine analytical situations.
