Aklavinone has an anthraquinone-based chromophore and its backbone highly resembles the kernel of some anthracycline antibiotics that possess anticancer activity, e.g., daunomycin. Since aklavinone's structure possesses many -OH groups and 2 keto groups, it is quite probable that certain tautomeric equilibria may occur. Presently, aklavinone prototropic tautomers possessing embedded anthraquinone moiety have been investigated quantum chemically by using density functional theory at the levels of RB3LYP/6-31G(d) and RB3LYP/6-31G(d,p). Additionally, IR spectra of the tautomers were calculated. Moreover, the phenolate ions obtained from the most stable tautomer in water were considered, and the protonation of this tautomer at various possible sites was investigated quantum chemically.

From Homoconjugated Push-Pull Chromophores to Donor-Acceptor-Substituted Spiro Systems by Thermal Rearrangement Dengiz, Çağatay; KATO, Shin-ichiro; ZALIBERA, Michal; CIAS, Pawel; SCHWEIZER, W. Bernd; BOUDON, Corinne; GISSELBRECHT, Jean-Paul; GESCHEIDT, Georg; DIEDERICH, Francois (Wiley, 2014-01-27) Series of homoconjugated push-pull chromophores and donor-acceptor (D-A)-functionalized spiro compounds were synthesized, in which the electron-donating strength of the anilino donor groups was systematically varied. The structural and optoelectronic properties of the compounds were investigated by X-ray analysis, UV/Vis spectroscopy, electrochemistry, and computational analysis. The homoconjugated push-pull chromophores with a central bicyclo[4.2.0]octane scaffold were obtained in high yield by [2+2] cyclo...
One-step synthesis of hierarchical [B]-ZSM-5 using cetyltrimethylammonium bromide as mesoporogen Yalcin, Busra Karakaya; İpek Torun, Bahar (The Scientific and Technological Research Council of Turkey, 2020-01-01) One-step facile synthesis of boron containing ZSM-5 microspheres is developed using 1,6-diaminohexane as the structure-directing agent and cetyltrimethylammonium bromide as the mesoporogen. High boron incorporation up to Si/B ratio of 38 is achieved and evidenced by the stretching vibrations of B-O-Si at 667 cm(-1) and 917 cm(-1) using Fourier-transform infrared spectra. The morphology of the crystals resembles berry-like spheres with sizes approximately 15 mu m, which is composed of aggregated nanocrystals...
A conjugated gold nanoparticle-azacyanine off-on-off fluorescence probe for sensitive and selective detection of G-quadruplexes Bilgen, Ecenaz; Forough, Mehrdad; Persil Çetinkol, Özgül (Elsevier BV, 2020-09-01) G-quadruplex secondary structures have gained significant recognition due to the discovery of their involvement in regulation of gene expression and their association with many diseases such as cancer and neurological disorders. Consequently, the need for the recognition and characterization of G-quadruplex structures has increased considerably. Here, we present a rapid, facile and sensitive off-on-off in vitro platform for G-quadruplex detection, based on the gold nanoparticle-azacyanine5 (AuNP-Aza5) conju...
Chemical characterization and anticholinesterase effects of essential oils derived from Salvia species TEMEL, HALİDE EDİP; Demirci, Betul; Demirci, Fatih; CELEP, FERHAT; KAHRAMAN, AHMET; Doğan, Musa; Baser, Kemal Husnu Can (Informa UK Limited, 2016-01-01) Inhibitory effect of Salvia species herbal preparations on acetylcholinesterase (AChE) and butylcholinesterase (BuChE) activitiy may contribute to regulation of cognitive performance and impaired cholinergic functions in patients with Alzheimer's disease. This functional role of Salvia species and their components makes the investigations on Salvia valuable in medicine-related plant research. Within this work it was aimed to investigate the in vitro anti-cholinesterase effect of essential oils derived from ...
Isotope Fractionation Associated with the Biodegradation of 2-and 4-Nitrophenols via Monooxygenation Pathways Wijker, Reto S.; Kurt, Zöhre; Spain, Jim C.; Bolotin, Jakov; Zeyer, Josef; Hofstetter, Thomas B. (American Chemical Society (ACS), 2013-12-17) Monooxygenation is an important route of nitroaromatic compound (NAC) biodegradation and it is widely found for cometabolic transformations of NACs and other aromatic pollutants. We investigated the C and N isotope fractionation of nitrophenol monooxygenation to complement the characterization of NAC (bio)degradation pathways by compound-specific isotope analysis (CSIA). Because of the large diversity of enzymes catalyzing monooxygenations, we studied the combined C and N isotope fractionation and the corre...
