Hydrogen cyanide (HCN) poisoning due to amygdalin (AMY) in apricot seeds is one of the public health issues Turkey. The aim this study was investigate AMY content 13 different including bitter and sweet ones, which are either sulfurized or roasted. determined by a high-performance liquid chromatography. Release HCN predicted total amount can cause calculated. mean 26 ± 14 mg g−1 that 0.16 0.09 g−1. consumption small amounts may poisoning.

The antioxidant, antimalarial, antibacterial, and antitumor activities of thiosemicarbazones have made this class compounds important for medicinal chemists. In addition, are among the most potent well-known ribonucleotide reductase inhibitors. study, 24 new thiosemicarbazone derivatives were synthesized, structures purity determined by IR, 1 H NMR, 13 C mass spectroscopy, elemental analysis. IC50 values these with an assay inhibition. Compounds 19, 20, inhibited enzyme activity at a higher...

Aromatic oximes are reduced in aqueous solution a four-electron process. The reducible species the pH range 5−8 is diprotonated form of oxime. This generated course electrolysis vicinity electrode surface from adsorbed neutral reduction initiated by cleavage N−O bond. diprotonation facilitates process preformation OH2+ as good leaving group and positive charge on azomethine nitrogen. Diprotonation has been proven based shapes i = f(pH) plots, observed shifts half-wave potentials with...

Abstract Dienogest is a synthetic oral progestogen with unique pharmacological properties that used orally in the treatment of endometrosis. The first time, detailed electrochemical mechanism dienogest investigated different aqueous mediums. Different progestins were to understand completely oxidation mechanism. was systematically by cyclic voltammetry, differential pulse and square wave voltammetry. A simple adsorptive stripping voltammetry method has been developed for fully validated...

The investigation of electrochemical reduction capecitabine on DME resulted in a scheme that involves two electron the C=O bond six membered heterocyclic ring and comparison with model compounds such as benzophenone, 5-fluorouracil cytosine supported observed behavior. Reporting an inexpensive, simple, rapid validated method for determination was achieved by DPP good precision, accuracy reproducibility. This work emphasizes polarography to be best choice when studying mechanisms presents...

Dienogest (DGN), is an orally administered synthetic progestin that has shown to have selective progesterone receptor (PR) agonistic activity and oral progestational potency on endometrium. In this paper, the investigation of electrochemical reduction dropping mercury electrode (DME) achieved resulted in a scheme involves two electron 3-keto-delta-4-group A-ring molecule. This observation supported by comparison compound with model compounds testosterone norethisterone. study, determination...
