Sulfonamidyls. 5. Electron Spin Resonance Spectroscopic Evidence for Four- and Five-Membered-Ring Sulfonamidyls and Sulfonyl Nitroxides

Cyclic sulfonamidyl radicals, generated by photolysis of the N-bromo (or N-chloro) beta- and gamma-sultams 1-3 and of N-bromo-2,3-dihydro-1,2-benzisothiazole 1,1-dioxide (4) have been characterized by solution ESR studies.The nitrogen and beta hyperfine splitting constants of 1-4 are in agreement with a PiN electronic ground state involving a planar geometry around the nitrogen free radical center.The corresponding nitroxides (6-9) were generated from 1-4 by reaction with nitrogen dioxide.In the same way, four additional sulfonyl nitroxides (10-13), derived from 3-alkyl-1,2 -thiazoline 1,1-dioxide systems, were generated and studied by ESR.The possible geometry around the nitroxide nitrogen atom and further conformational implications are discussed.

Anti-inflammatory effects of novel thiazolidinone derivatives as bioactive heterocycles on raw264.7 Cells

The inhibition of the inducible nitric oxide synthase (iNOS), cyclooxygenase 2 (COX-2) and nuclear factor-XB (NF-XB) production are research targets of attract in the field of anti-inflammatory drug development. Therefore, this study was designed to investigate the anti-inflammatory effects of novel thiazolidinone derivatives using a cellular model of lipopolysaccharide (LPS)-stimulated murine macrophage RAW 264.7. In the present study, five new derivatives (A to E) of thiazolidinone were synthesized and screened for anti-inflammatory activities. Cell viability of LPS-stimulated RAW 264.7 macrophages clearly decreased in <55 mug/mL of synthesized A-E compounds especially in the presence of C; therefore, up to 50 mug/mL of compounds were selected for the subsequent analysis. A majority of these compounds showed significant inhibition on the production of NO in LPS-stimulated macrophages in a dose-dependent manner. Compounds B and D (10-50 mug/mL) significantly inhibited LPS-induced NF-XB (p65) production in a dose-dependent manner. The effects of B and D on iNOS and COX-2 mRNA and protein expression in LPS-stimulated RAW 264.7 cells were detected by real time-PCR and western blot. B derivative significantly suppressed the iNOS and COX-2 mRNA level and as well as protein expression. Taken together, these results reveal that compound B as new thiazolidinone derivative decreased expression of the inflammatory-related signals (NO, iNOS and COX-2) through regulation of NF-XB; hence, this compound could be suggested as a novel therapeutic strategy for inflammation-Associated disorders. A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.

Synthesis of novel 2-Thioxothiazolidin-4-one and thiazolidine-2, 4-dione derivatives as potential anticancer agents

A variety of novel thiazolidine derivatives (2-Thioxothiazolidin-4-one and thiazolidine-2, 4-dione derivatives) have been prepared by using 2,4-diphenyl-2Hchromene- 3-carbaldehyde and its derivatives as starting materials. This is the first example of the preparation of thiazolidine derivatives through this novel method. Structure evolution of the resulting thiazolidine derivatives leads to anticancer agents. Our preliminary data for some model compounds on three cancer cell lines (MCF7, A549 and B-16) suggested reasonable anticancer activity against the A549 and B-16 cell lines, with IC50 values of 20.7 and 20.4 muM, respectively. This method is operationally simple and works with a diverse range of substrates.

Recent developments of quinolone-based derivatives and their activities against Escherichia coli

Escherichia coli (E. coli) is the most common pathogen in both hospital and community settings, and is capable of causing infections that can lead to serious consequences. Quinolones, one of the most common antibiotics in clinical use, are effective weapons to treat E. coli infections. However, the resistance of E. coli to quinolones develops rapidly and spreads widely. Thus, it has become increasingly urgent to enhance the potency of quinolones against both drug-susceptible and drug-resistant E. coli. This review aims to summarize the recent developments of quinolone derivatives with potential activity against E. coli, and to discuss the structure-activity relationship for further rationale design of this kind of derivatives.

Defective phagocytosis in airways disease

Maintaining an airway clear of inhaled particles, pathogens, and cellular debris is paramount for lung homeostasis. In healthy individuals, the phagocytes of the innate immune system act as sentinels to patrol the airway and ensure sterility. However, in airways diseases, including asthma, COPD, and cystic fibrosis, there is a propensity for bacterial colonization that may contribute to disease worsening. Evidence suggests that this may be due to dysfunctional phagocytosis. In patients with COPD, phagocytosis of several bacterial species and removal of apoptotic cells (efferocytosis) by alveolar macrophages are significantly reduced; however, these cells can remove inert beads normally. Attenuated phagocytosis is also apparent in monocyte-derived macrophages from the same patients, suggesting an inherent defect in these cells. Reduced expression of cell surface recognition receptors has been suggested as one mechanism for these observations; however, the literature is currently contradictory and requires further clarification. In cystic fibrosis, a similar defect is also observed in both airway neutrophils and macrophages, leading to ineffective bacterial uptake and subsequent killing. In asthma and other airways diseases, there are also reports of defective phagocytosis of bacterial pathogens, although the relevance to disease pathophysiology is not understood. Oxidative stress is emerging as a common mechanism that may be altering both macrophage and neutrophil functions that can be reversed by various antioxidant strategies. The identification of this and other mechanisms underlying phagocyte dysfunction may present novel therapeutic opportunities for the treatment of many of these intractable diseases and improve patient morbidity and mortality.
