The use of N-acetylcysteine in intensive care

Objective: To review the actions and clinical use of serum N-acetylcysteine in the critically ill patient. Data sources: A review of articles published on the mechanisms of action and clinical use of N-acetylcysteine. Summary of review: N-acetylcysteine (NAC) is an amino acid with a MW of 163.2. It acts as an antioxidant, both directly as a glutathione substitute and indirectly as a precursor for glutathione. It also causes vasodilation by increasing cyclic guanosine monophosphate levels, inhibits platelet aggregation, acts as a sulphydryl donor to regenerate endothelial-derived relaxing factor and reduces IL-8 and TNF-alpha production. While there is evidence for its effectiveness as an antidote to paracetamol poisoning, its use in other disorders has only experimental or anecdotal support. For example, in hepatic failure, there are few studies in man showing improved outcome following NAC therapy. There is also conflicting evidence for the use of NAC in sepsis or ARDS and while there is some evidence to suggest that NAC may be of benefit in acute myocardial infarction, the patient numbers are small. It may also be of use in ameliorating nitrate tolerance. It is also possible that NAC may confer benefit in reducing the risks of radiographic contrast nephropathy, although the study suggesting this was probably insufficiently powered to review all patient subsets (e.g. diabetics). N-acetylcysteine would also appear to enhance T cell function in HIV infected patients. However, the use of NAC for immunomodulation in HIV patients has not yet undergone prospective randomised controlled trials and therefore cannot be recommended as routine therapy in HIV infected, or other immune deficient, patients. There is currently insufficient evidence to propose NAC for the treatment of carbon monoxide poisoning. Whilst there is experimental evidence for a variety of novel roles for NAC, further clinical studies are required before it can be recommended for the routine management of any disorders other than that of paracetamol poisoning. Conclusions: N-acetylcysteine has antioxidant properties that may be useful in many clinical conditions. Currently, however, it can only be recommended as therapy for paracetamol poisoning, in all other disorders it is still under evaluation.

Synthesis, characterization, and DFT modeling of novel organic compound thin films derived from 2-amino-4-(2-hydroxy-3-methoxyphenyl)-4H-thiazolo[3,2-a][1,3,5]triazin-6(7H)-one

A smooth and effective protocol was proven to produce 2-amino-4-(2-hydroxy-3-methoxy-phenyl)-6-oxo-4H-thiazolo[3,2-a][1,3,5]triazine [2aTZ] via one-pot ternary condensation of easily available mercaptoacetic acid, o-vanillin and dicyandiamide along with ammonium acetate (CH3COONH4) as a catalyst. The chemical structure of the compound and its thin-film [2aTZ]TF were characterized by Fourier-Transform Infrared spectroscopy (FT-IR), Proton Nuclear Magnetic Resonance (1HNMR), Carbon Nuclear Magnetic Resonance (13CNMR), X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) analyses. The optimization of the molecular structure, vibrational spectra and optical properties have been accomplished depends on the density functional theory (DFT) utilizing DMol3 and Cambridge Serial Total Energy Package (CASTEP) programs for [2aTZ] as the isolated molecule and crystal models. It’s very well-referred to the molecule’s structure and their contacts. They are equated with data calculated by means of various theoretical methodologies. [2aTZ]TF is fabricated by spin coating (250 ¡À 3 nm) and its optical properties (optical band gaps, Eg Opt, absorption index, k, reflective index, n, dielectric constant, epsilon, and optical conductivity,sigma) are also investigated. The high accurateness of the new [2aTZ] along with its suitable optical bandgap provided us to construct a photodetector and demonstrating its potential in optoelectronic implementations.

Native Chemical Ligation and Extended Methods: Mechanisms, Catalysis, Scope, and Limitations

The native chemical ligation reaction (NCL) involves reacting a C-terminal peptide thioester with an N-terminal cysteinyl peptide to produce a native peptide bond between the two fragments. This reaction has considerably extended the size of polypeptides and proteins that can be produced by total synthesis and has also numerous applications in bioconjugation, polymer synthesis, material science, and micro- and nanotechnology research. The aim of the present review is to provide a thorough mechanistic overview of NCL and extended methods. The most relevant properties of peptide thioesters, Cys peptides, and common solvents, reagents, additives, and catalysts used for these ligations are presented. Mechanisms, selectivity and reactivity are, whenever possible, discussed through the insights of computational and physical chemistry studies. The inherent limitations of NCL are discussed with insights from the mechanistic standpoint. This review also presents a palette of O,S-, N,S-, or N,Se-acyl shift systems as thioester or selenoester surrogates and discusses the special molecular features that govern reactivity in each case. Finally, the various thiol-based auxiliaries and thiol or selenol amino acid surrogates that have been developed so far are discussed with a special focus on the mechanism of long-range N,S-acyl migrations and selective dechalcogenation reactions.

Evaluation of hypoglycemic effects of 4-thiazolidinones

Nicotinic acid, a well-known hypolipidemic drug, is known to produce elevation of blood glucose in humans. In an earlier study in our laboratory, a thiazolidinone derivative of nicotinic acid was shown to exert hypolipidemic effect. The present study was aimed to find out if this compound produced any elevation of blood glucose in normal and diabetic Wistar rats. A closely related thiazolidinone was also evaluated. The two compounds reduced blood glucose in both normal and diabetic rats, while nicotinic acid produced hyperglycemia. The thiazolidinone structure with its hypoglycemic potential may be opposing the glucose elevating effect of nicotinoyl moiety. It is concluded from the study that the thiazolidinone derivative of nicotinic acid is a hypoglycemic agent besides being hypolipidemic. Detailed investigation is warranted.

Delivery of peptide and protein drugs over the blood-brain barrier

Peptide and protein (P/P) drugs have been identified as showing great promises for the treatment of various neurodegenerative diseases. A major challenge in this regard, however, is the delivery of P/P drugs over the blood-brain barrier (BBB). Intense research over the last 25 years has enabled a better understanding of the cellular and molecular transport mechanisms at the BBB, and several strategies for enhanced P/P drug delivery over the BBB have been developed and tested in preclinical and clinical-experimental research. Among them, technology-based approaches (comprising functionalized nanocarriers and liposomes) and pharmacological strategies (such as the use of carrier systems and chimeric peptide technology) appear to be the most promising ones. This review combines a comprehensive overview on the current understanding of the transport mechanisms at the BBB with promising selected strategies published so far that can be applied to facilitate enhanced P/P drug delivery over the BBB.
