Determination of Tryptophan and Kynurenine by LC-MS/MS by Using Amlodipine as an Internal Standard

Autor: Aylin Sepici Dinçel, Burcu Eser, Yeşim Özkan

Tryptophan is an essential amino acid that plays an important role in cell metabolism, and kynurenine is its main metabolic pathway. By using ultra-high-performance liquid chromatography coupled to electrospray ionization triple-quadrupole mass spect

Identification Of Small-Molecule Urea Derivatives As Novel Nampt Inhibitors Via Pharmacophore-Based Virtual Screening

Autor: Fikriye Ozgencil, Yeşim Özkan, Sezen Guntekin-Ergun, Gokcen Eren, Rengul Cetin-Atalay

Nicotinamide phosphoribosyltransferase (NAMPT) catalyzes the condensation of nicotinamide (NAM) with 5-phosphoribosyl-1-prophosphate (PRPP) to yield nicotinamide mononucleotide (NMN), a rate limiting enzyme in a mammalian salvage pathway of nicotinam

Pharmacophore modeling and virtual screening studies to identify novel selective SIRT2 inhibitors

Autor: Selen Gozde Kaya, Mahmut Gozelle, Gokcen Eren, Rengul Cetin-Atalay, Agostino Bruno, Sezen Guntekin-Ergun, Gabriele Costantino, Yeşim Özkan, Fikriye Ozgencil

Sirtuins (SIRTs) are a class of NAD(+)-dependent protein histone deacetylases (HDACs) that catalyse the reversible deacetylation of lysine residues in the histones or non-histone substrates. Mammalian sirtuins consist of seven isoforms (SIRT1-7), whi
