The vicinal diaryl heterocyclic framework has been widely used for the development of compounds with significant bioactivities. In this study, a series of diaryl heterocycles were designed and synthesized based on an in-house diaryl isoxazole derivative (9), and most of the newly synthesized derivatives demonstrated moderate to good antiproliferative activities against a panel of hepatocellular carcinoma and breast cancer cells, exemplified with the diaryl isoxazole 11 and the diaryl pyrazole 85 with IC50 values in the range of 0.7-9.5 μM. Treatments with both 11 and 85 induced apoptosis in these tumor cells, and they displayed antitumor activity in vivo in the Mahlavu hepatocellular carcinoma and the MDA-MB-231 breast cancer xenograft models, indicating that these compounds could be considered as leads for further development of antitumor agents. Important structural features of this compound class for the antitumor activity have also been proposed, which warrant further exploration to guide the design of new and more potent diaryl heterocycles.

Planar-Chiral Bis-silanols and Diols as H-Bonding Asymmetric Organocatalysts BEEMELMANNS, Christine; HUSMANN, Ralph; Whelligan, Daniel K.; Özçubukçu, Salih; BOLM, Carsten (2012-06-01) The successful development of planar-chiral bis-silanols 3a-d and their application as asymmetric organocatalysts in hetero-Diels-Alder (HDA) reactions is described. All precursors were easily prepared by addition of commerically available silyl electrophiles to a dilithiated [2.2]paracyclophane derivative followed by silane oxidations. The analogous bis-carbinols 7a-c have been prepared by addition of suitable Grignard reagents to bis-methoxycarbonyl derivative 6. Both racemic as well as enantiopure planar...
Viscoelastic properties of reactive and non-reactive styrene-maleic anhydride olefinic blends Bayram, G; Yılmazer, Ülkü; Xanthos, M (2000-05-11) Reactive blends of styrene-maleic anhydride (SMAH) with polyethylene/methyl acrylate/glycidyl methacrylate (PE-F) and non-reactive blends of SMAH with polyethylene/methyl acrylate (PE-NF) were produced and characterized in terms of morphology and viscoelastic properties in order to understand the reaction characteristics between anhydride/epoxy functional groups. Storage modulus, G', loss modulus, G " and complex viscosity, eta* of reactive blends at 25 % and 50 % PE-F were higher than those of non-reactive...
Asymmetric synthesis of chiral camphor fused pyridine type novel organocatalysts Küçükdişli, Murat; Tanyeli, Cihangir; Department of Chemistry (2009) Chiral pyridines as organocatalysts have been used in asymmetric organic synthesis in recent years. The asymmetric synthesis of camphor fused pyridine type novel organocatalysts were perfomed starting from cheap and easily available natural (+)-camphor. Using camphor fused pyridine skeleton, six organocatalysts 29, 32, 33, 38, 40, and 41were successfully synthesized. The first four nucleophilic and Lewis base catalysts 29, 32, and 33 are different P-oxides and P,N-dioxides which were tested in allylation of...
Enantioselective aza-Henry reaction of t-boc protected imines and nitroalkanes with bifunctional squaramide organocatalysts Susam, Dilşad; Tanyeli, Cihangir; Department of Chemistry (2015) The first part of this thesis comprises the application of a Cinchona alkaloid derived, bifunctional squaramide organocatalyst in the aza-Henry reaction of t-Boc protected imines and nitroalkanes. The target chiral β-nitroamines are chosen because; they are quite feasible for the corresponding α-amino acids and 1,2-diamines, which are basic structural motif in many natural products and key materials of the many pharmaceuticals. In this part, 12 different chiral β-nitroamine derivatives were synthesized with...
Susceptibility indexing method for irrigation water management planning: Applications to K. Menderes river basin, Turkey Pusatli, O. Tolga; Camur, M. Zeki; Yazıcıgil, Hasan (2009-01-01) A susceptibility indexing method was developed based oil vulnerability and quality indices. The contamination Susceptibility index (SI) at a given location was calculated by taking file product Of the Vulnerability index (VI) and the quality index (QI): SI = VI x QI. This method incorporates both hydrogeological and hydrochemical data for a comprehensive index mapping. The DRASTIC index methodology was used for the hydrogeological data evaluations. The quality index calculation procedure based oil a water q...
