This study presents the synthesis of a series of new tetra-substituted phthalocyanines bearing 3,5-bis(trifluoromethyl)phenoxy groups at non-peripheral positions. The resulting macromolecules were characterized by performing different spectroscopic methods including H-1 NMR, UV-Vis, FT-IR, and mass spectroscopy. In this study, the synergistic effect of phthalocyanines used as colorants in ink formulas with other chemicals available was probed for the first time. The synergistic effect of methyl laurate on the biological and antioxidant activities of the compounds (2-5) was investigated. Moreover, the therapeutic properties of the complexes (3, 6, and 7) were investigated using photochemical methods. Upon comparison, complex 7 (phi(Delta) = 0.42) was found to be more effective than complex 6 (phi(Delta) = 0.40) and complex 3 (phi(Delta) = 0.27) in terms of producing singlet oxygen. The results confirmed that the heavy atom effect improves the therapeutic effects.

Development of acyl anion precursors and their applications
Reis, Ömer; Demir, Ayhan Sıtkı; Department of Chemistry (2005)
This thesis presents the development of new acyl anion precursors and their applications. The main concern of this thesis was to make use of acyl anion precursors in catalytic bond forming reactions. Toward this aim, previously known cyanide ion catalyzed cleavage of benzils was investigated in scope and efficiency in unsymmetrical benzoin condensation. Although benzils were proved to be useful entities as acyl anion precursors in benzoin condensation, they suffer some major drawbacks. Therefore acylphospho...
INVESTIGATION OF PHOTOFERMENTATIVE POLY-HYDROXYBUTYRATE (PHB) AND HYDROGEN PRODUCTION VIA RHODOBACTER CAPSULATUS
Hoşafcı, Ertan; Bayramoğlu, Tuba Hande; Koku, Harun; Department of Environmental Engineering (2023-1-26)
The aim of this thesis study is to investigate factors affecting hydrogen (H2) and poly-hydroxybutyrate (PHB) production via photofermentation using two strains of Rhodobacter capsulatus species. To this purpose, three experimental designs were set up, namely Set 1, Set 2 and Set 3. In Set 1, various approaches in pretreatment of bacterial biomass were investigated. For R. capsulatus Wild Type (WT) strain, employment of different pretreatment methods did not make a significant difference, where an average ...
Investigation of chemopreventive and apoptotic characteristics of turkish medicinal plant rheum ribes
Uyar, Pembegül; Çoruh, Nursen; İşcan, Mesude; Department of Biotechnology (2011)
Rheum species are medicinally important plants due to the presence of anthracene derivatives and in this study antioxidative, cytotoxic, apoptotic and chemopreventive characteristics of R. ribes extracts were evaluated. R. ribes shoot and root dry powder samples were prepared and extracted with ethyl acetate, ethanol and water. The extracts were revealed to be a potential scavenger of DPPH radicals and the chemical composition of the extracts was quantified by colorimetric determination of total phenol (GAE...
INVESTIGATION OF THE INFLUENCE OF PRESSURE ON THE COMBUSTION OF ALPAGUT LIGNITE
Altun, Naci Emre; Kök, Mustafa Verşan (Springer Science and Business Media LLC, 2008-10-01)
This research presents the combustion behavior of lignite under different reaction pressures. Lignite from Alpagut, Corum of Turkey was combusted in its run off mine (ROM) condition under three different pressure levels of 172, 345, 517 kPa (25, 50, 75 psi). Experiments were done in a fully controlled temperature regime in an isolated combustion tube that operated in coordination with a continuous gas analyzer. Combustion behavior of lignite under different pressures was characterized by effluent gas analys...
Predicting the effect of hydrophobicity surface on binding affinity of PCP-like compounds using machine learning methods
Yoldaş, Mine; Alpaslan, Ferda Nur; Büyükbingöl, Erdem; Department of Computer Engineering (2011)
This study aims to predict the binding affinity of the PCP-like compounds by means of molecular hydrophobicity. Molecular hydrophobicity is an important property which aff ects the binding affinity of molecules. The values of molecular hydrophobicity of molecules are obtained on three-dimensional coordinate system. Our aim is to reduce the number of points on the hydrophobicity surface of the molecules. This is modeled by using self organizing maps (SOM) and k-means clustering. The feature sets obtained fro...
