Item 1,15-diaza-3,4:12,13-dibenzo-5,8,11-trioxacycloheptadecane hemihydrate(2003) Bilge, Selen; Kılıç, Zeynel; Fen FakültesiThe title compound, C20H26N2O 3·0.5H2O, contains a 17-membered diaza-crown ether ligand with three ether O and two N atoms. It consists of the macrocyclic ligand and one half water molecule; the latter possesses crystallographically imposed C2 symmetry. In the macrocyclic ring, the mean N⋯O distance is 3.995 (4) A. The macrocyclic inner hole size, estimated as twice the mean distance of the donor atoms from their centroid, is approximately 1.29 Å. © 2003 International Union of Crystallography Printed in Great Britain - all rights reserved.Item 1-n-Butyl-2-(4′-fluorophenyl)-1H-benzimidazole-6-carbonitrile(2004) Göker, Hakan; Kuş, Canan; Eczacılık FakültesiThe structure of the title compound, C18H16FN3, consists of neutral molecules. The asymmetric unit contains two independent molecules with similar conformations: the dihedral angles between the benzimidazole moiety and the benzene rings are 34.99 (9) and 36.08 (8)°. The crystal structure is stabilized by dipole-dipole and van der Waals interactions.Item 16+ spin-gap isomer in Cd96(2011) Ataç, Ayşe; Fen FakültesiA β-decaying high-spin isomer in Cd96, with a half-life T 1/2=0.29-0.10+0.11s, has been established in a stopped beam rare isotope spectroscopic investigations at GSI (RISING) experiment. The nuclei were produced using the fragmentation of a primary beam of Xe124 on a Be9 target. From the half-life and the observed γ decays in the daughter nucleus, Ag96, we conclude that the β-decaying state is the long predicted 16 + "spin-gap" isomer. Shell-model calculations, using the Gross-Frenkel interaction and the πν(p1/2,g9/2) model space, show that the isoscalar component of the neutron-proton interaction is essential to explain the origin of the isomer. Core excitations across the N=Z=50 gaps and the Gamow-Teller strength, B(GT) distributions have been studied via large-scale shell-model calculations using the πν(g,d,s) model space to compare with the experimental B(GT) value obtained from the half-life of the isomer. © 2011 American Physical Society.Item 2,2′-[1,1′-(Propane-2,2-diyldiimino)-diethyl-idene]-diphenol(2007) Atakol, Orhan; Kenar, Adnan; Fen FakültesiItem 2,6-Dimethyl-4H-1-benzopyran-4-one(2004) Göker, Hakan; Eczacılık FakültesiThe title compound, C11H10O2, belongs to the class of 4-benzopyrones (also known as chromen-4-ones) with potentially diverse pharmacological activities. It was synthesized by acylation of 2-hydroxy-4-methylacetophenone with ethyl acetate in the presence of sodium hydride and subsequent cyclization by hydrochloric acid. All non-H atoms of the substituted bicyclic molecule are coplanar within 0.03 Å. C-H...O interactions [C...O = 3.272 (5) Å] link neighbouring molecules related by the 21 axisItem 2-Acetylphenyl 5-methylthiophene-2-carboxylate(2003) Göker, Hakan; Fen FakültesiThe non-H atoms of the molecule of the title compound, C14H 12O3S, form three essentially planar fragments, viz. the thiophene ring with the methyl C atom and carboxylate group (maximum deviation 0.041 Å; fragment A), the oxyphenyl ring with the central acetyl C atom (0.029 Å; B), and the acetyl group together with the phenyl C atom bonded to it (<0.001 Å; C). These planes form dihedral angles of 88.33 (7)° for A/B and 71.9 (2)° for B/C. The crystal structure is stabilized by intermolecular interactions of the C - H⋯O type [C⋯O = 3.492 (5) Å]. © 2003 International Union of Crystallography Printed in Great Britain - all rights reserved.Item 3-(4-Chlorobenzyl)-5-(4-oxo-4H-chromen-3-ylmethylene)-1,3-thiazolidine-2,4-dione(2005) Bozdağ Dündar, Oya; Ertan, Rahmiye; Ünlüsoy, Meltem Ceylan; Eczacılık FakültesiIn the title molecule, C20H12ClNO4S, the benzopyran ring system and the thiazolidine ring are planar. The dihedral angle between the chlorobenzyl and thiazolidine rings is 74.42 (8)°. The crystal structure is stabilized by intermolecular C-H...O hydrogen bonds.Item 3-Ethyl-5-(4-oxochroman-3-ylmethylene)- 1,3-imidazolidine-2,4-dione(2007) Ünlüsoy, Meltem Ceylan; Ertan, Rahmiye; Eczacılık FakültesiItem 3-Methyl-5-(4-oxo-4H-chromen-3-ylmethylene)-1,3-thiazolidine-2,4-dione(2006) Ünlüsoy, Meltem Ceylan; Ertan, Rahmiye; Eczacılık FakültesiItem 4,4,6,6-Tetrachloro-1′,3′-[2,2′-(3-oxapentane-1,5-dioxy) dibenzyl]-2λ5,4λ5,6λ5- cyclotriphosphazene-2-spiro-2′-1,3,2-diazaphospholane benzene hemisolvate(2004) Bilge, Selen; Demiriz, Şemsay; Kılıç, Zeynel; Fen Fakültesi.

The phosphazene and the two six-membered N/O rings are not planar. The aliphatic C atom (in ArCH-OAr) and the N atom (in ArCH2-N), which has a pyramidal geometry, are capable of representing stereogenic centres.Item 4-Thiazolidinone derivatives as mmp ınhibitors in tissue damage: synthesis, biological evaluation and docking studies(2018) Yalçın, İsmail; Ertan, Tuğba Bolelli; Eczacılık FakültesiNine 2-(1,2-benzothiazol-3-yl)-N-(4-oxo-2-phenyl-1,3-thiazolidin-3-yl)propanamides combining a benzisothiazole and 4-thiazolidinone in one framework were designed and synthesized. The aim of the study was to verify their effectiveness to affect the inflammatory/oxidative process in which free oxygen and nitrite (ROS and RNS) radicals, inflammatory mediators, such as nuclear factor kappa B (NF-kappa B), and matrix metalloproteinases (MMPs) are involved. Docking studies of all the compounds were performed in order to explore their binding mode at the MMP-9 protein. An appreciable anti-inflammatory/potential wound healing effects of the tested compounds was highlighted. Derivative 23, bearing a 4-carboxyphenyl substituent at C2 of the 4-thiazolidinone ring, exhibited the highest activity, being able to inhibit MMP-9 at nanomolar level(IC50 = 40 nM).Item 40,40,60,60-Tetrachloro-3-(4,6-dimethylpyridin-2-yl)- 3,4-dihydrospiro[1,3,2-benzoxazaphosphinine2,20-(2k5 ,4k5 ,6k5 -cyclotriphosphazene)](2006) Kılıç, Zeynel; Fen FakültesiItem 5-[4-Chloro-2-(4-chlorobenzylsulfanyl)- thiazol-5-ylmethylene]-3-(2,4-dichlorobenzyl)thiazolidine-2,4-dione(2007) Bozdağ Dündar, Oya; Ertan, Rahmiye; Fen FakültesiItem 60,60-Dichloro-3,300-etheno-3,4,300,400- tetrahydro-2H-1,3-benzoxazine-2-spiro20-(2k5 ,4k5 ,6k5 -cyclotriphosphazene)-40 - spiro-200-2H-1,3-benzoxazine(2004) Bilge, Selen; Natsagdorj, Amgalan; Demiriz, Şemsay; Kılıç, Zeynel; Fen FakültesiItem 7,11-(Butane-1,4-diyldioxydi-o-phenylenedimethylene)-6,6-dichloro-4,4-bis(pyrrolidin1-yl)-2k5 ,4k5 ,6k5 -triphosphaza-1,3,5,7,11- pentaazaspiro[5.5]undeca-1,3,5-triene(2005) Asmafiliz, Nuran; İlter, Elif Ece; Kılıç, Zeynel; Fen FakültesiThe title compound, C29H42Cl2N7O2P3, is a phosphazene derivative with a bulky substituent attached through a spiro junction with two pyrrolidine rings.
