Algebraic surfaces of the laplace-beltrami operators of the TF-type surfaces
(Yıldız Teknik Üniversitesi, 2015)We study on a new kind of surface covered by translation and factorable (TF-type) surfaces in the three dimensional Euclidean space. We calculate I and III Laplace-Beltrami operator surfaces of a TF-type ... -
Alleviation of copper stress with homobrassinosteroid in germinating sunflower roots
(Fresenius Environmental Bulletin, 2016-11)We investigated potential alleviation effects of homobrassinosteroid (HBR) hormone on sunflower (Helianthus annuus L. cv. TR003) grown under copper (Cu) stress conditions. Seeds were grown under Cu (30 µM and 40 µM) ... -
Aminopyrazole‐substituted metallophthalocyanines: Preparation, aggregation behavior, and investigation of metabolic enzymes inhibition properties
(Wiley, 2019-02)The synthesis, characterization, aggregation behavior, theoretical studies, and investigation of antimicrobial, antidiabetic, and anticholinergic properties of 4-(2-(5-amino-4-(4-bromophenyl)-3-methyl-1H-pyrazol-1-yl)eth ... -

Anticancer activities and mechanism of action of 2 novel metal complexes, C16H34N8O5Ag2Cd and C11H16N7O2Ag3Ni
(TÜBİTAK, 2014-11-24)The discovery of anticancer activity in cisplatin triggered the development of novel drugs containing metals such as platinum or ruthenium. Extremely diverse structural chemistry and the interaction of metal complexes with ... -
Antidiabetic and antiparasitic potentials: Inhibition effects of some natural antioxidant compounds on α-glycosidase, α-amylase and human glutathione S-transferase enzymes
(Elsevier, 2018-11)The glutathione S-transferase (GST) was purified from fresh blood erythrocytes using affinity column chromatography. Also, alpha-amylase from porcine pancreas and alpha-glycosidase from Saccharomyces cerevisiae were used ... -
Antidiabetic potential: In vitro inhibition effects of bromophenol and diarylmethanones derivatives on metabolic enzymes
(Wiley, 2018-12)Aldose reductase converts glucose to sorbitol in the polyol pathway. It is an important enzyme to prevent diabetic complications. In this study, we studied the inhibitory effects of bromophenol derivatives on aldose reductase ... -
Antidiabetic potential: in vitro inhibition effects of some natural phenolic compounds on -glycosidase and -amylase enzymes
(Wiley, 2017-10)-Glycosidase is a catalytic enzyme and it destroys the complex carbohydrates into simple absorbable sugar units. The natural phenolic compounds were tested for their antidiabetic properties as -glycosidase and -amylase ... -
Antioxidant activity of the aqueous extract of iris taochia and identification of its chemical constituents
(Indian Journal of Pharmaceutical Sciences, 2018-09)In this study, phytochemical components and antioxidant capacity of extracts obtained from Iris taochia plant, which is endemic to Caucasus, were investigated. Fifteen new compounds were detected and identified using a ... -
Antioxidant activity, acetylcholinesterase, and carbonic anhydrase inhibitory properties of novel ureas derived from phenethylamines
(Wiley, 2016-12)A series of ureas derived from phenethylamines were synthesized and evaluated for human carbonic anhydrase (hCA) I and II, acetylcholinesterase (AChE), and butyrylcholinesterase (BChE) enzyme inhibitory activities and ... -
Antioxidant and acetylcholinesterase inhibition properties of novel bromophenol derivatives
(Elsevier, 2015-06)In this study, series of novel bromophenol derivatives were synthesized and investigated for their antioxidant and AChE inhibition properties. Novel brominated diarylmethanones were obtained from the acylation reactions ... -
Antioxidant and anticholinergic properties of olivetol
(Wiley, 2018-06)Olivetol is a pioneer in diverse syntheses of tetrahydrocannabinol. It is produced by a type of insects, which is used as a pheromone, antiseptic, or repellent agent. In this study, we evaluated the antioxidant properties ... -
Antioxidant, antimicrobial and anticancer activities of the aspergillin pz and terphenyllin secondary metabolites: an in vitro study
(Gazi University Journal of Science, 2019-09-01)The importance of secondary metabolites obtained from fungi is increasing day by day in terms of human health. Many physiological and pharmacological effects, mainly antimicrobial, anticancer and antioxidant properties of ...
