Synthesis and antimicrobial activities of novel bisacridine-1,8-dione derivatives

WOS: 000288398900005A series of bisacridine-1,8-dione derivatives were synthesized by one-pot reaction of aromatic dialdehydes, dimedone or cyclohexane-1,3-dione and primer aromatic amines in acetonitrile to utilizing Amberlyst-15 as a heterogeneous catalyst. The structures of compounds were characterized by FT-IR, NMR, and elemental analysis. Antimicrobial activities of these compounds were determined by using the disc diffusion method against to these gram-positive and gram-negative bacteria and yeast. The results were compared with reference discs.Dumlupinar University [2008-4]The authors are very grateful to Dumlupinar University Research Fund for providing financial support for this project (Grant No. 2008-4)

Synthesis, electrochemical, and antibacterial activity of some novel N(4)O(2) ligand derivativies

A novel ligand has been synthesized by the condensation of 1,3-diaminoprophane (HL) with isonitroso-p-chloroacetophenone. The complexes of cobalt(II), nicel(II), cupper(II) and zinc(II) with HL were prepared. All compounds were characterized by spectroscopic techniques and its antibacterial activities were determined by the disc diffusion method used against to those gram-positive and-negative bacteria. All compounds were investigated by cyclic voltammetry at 25 degrees C. The voltammograms were recorded with a potential scan of 100 mV s(-1)

Cytokine expression profiles in Autism spectrum disorder: A multi-center study from Turkey.

Autism Spectrum Disorder (ASD) is a complex neurodevelopmental disorder characterized by impairments in communication and social interaction as well as restricted interests and repetitive behaviors. The pathogenesis of ASD is not completely understood, but a growing body of research has demonstrated that the immune response may be a contributing factor in the etiology and/ or ontogeny of ASD. The aim of this study was to determine the expression levels of IL-1β, IL-1α, IL-4, IL-6, IL-17, TNF-α and TGF-β in peripheral blood mononuclear cells of children with ASD and healthy controls in order to determine the contributions of cytokines to ASD. Within the study timeframe, 195 children with ASDs (80.5% male) and 162 controls (73.6% male) were enrolled. Most children with ASD had a comorbid disorder (n = 114, 58.5%), with the most common diagnoses as Intellectual Developmental Disorder (IDD, n = 64, 32.8%) and ADHD (n = 64, 32.8%). The majority of children with ASD had severe autistic symptoms as evaluated via Childhood Autism Rating Scale (CARS, n = 130, 64.6%). The mean CARS score in the ASD sample was 40.8 (S.D. = 7.6). The patients with ASD were found to have significantly higher levels of IL-6 (p < 0.001) and significantly lower levels of IL-17 (p < 0.05, all Bonferroni corrected). Treatment tended to affect IL-4 levels. Lastly, discriminant function analysis (DFA) revealed that a combination of IL-6, IL-17 and IL-1α correctly classified 56.6% of cases. Despite extensive immunological evidence suggesting immune system aberrations, further research is required to clarify the relationship between immune profiles and ASD symptoms
