The hydrazinophthalazines-derivates (syn. hydrazine) hydralazine and dihydralazine were approved by the FDA as anti-hypertensives in 1953 – and because they are both effective and safe they are among the oldest drugs which have kept their place in clinical practice. While hydrazine was originally discovered as potent vasodilatator which lowered blood pressure and increased renal perfusion, it r...

Four novel unsymmetrical β-diketiminates 2-(2,6-diisopropylphenyl)amino-4-(phenyl)imino-2-pentene (4a), 2-(2,6-diisopropylphenyl)amino-4-(4-methylphenyl)imino-2-pentene (4b), 2-(2,6-diisopropylphenyl)amino-4-(4-methoxyphenyl)imino-2-pentene (4c) and 2-(2,6-diisopropylphenyl)amino-4-(4-chlorophenyl)imino-2-pentene (4d) were synthesized with a 77-84% yield, and were characterized by spectroscopic...

We report on hydrazine-sensing organic electrochemical transistors (OECTs) with a design consisting of concentric annular electrodes. The design engineering of these OECTs was motivated by the great potential of using OECT sensing arrays in fields such as bioelectronics. In this work, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)-based OECTs have been studied as aqueous se...

Seven synthetic tetrahydroquinolines with different substitution patterns were obtained by an imino Diels-Alder condensation reaction and were evaluated against phytopathogenic fungi. Compounds with a methoxy group showed interesting activity against Cladosporium cladosporoides with a MIC value of 13.75 microg/mL

Hydrazide chemistry is a powerful technique in glycopeptides enrichment. However, the low density of the monolayer hydrazine groups on the conventional hydrazine-functionalized magnetic nanoparticles limits the efficiency of glycopeptides enrichment. Herein, a novel magnetic nanoparticle grafted with poly(glycidyl methacrylate) (GMA) brushes was fabricated via reversible addition-fragmentation ...

It has been known since the studies of Neubauer in 1909 and of Knoop in 19107"' that the mammalian organism is able to degrade a-amino acids to a-keto acids. Knoop advanced the hypothesis that this degradation involved an oxidative deamination.' According to this hypothesis, the imino derivative of the amino acid is first formed in an oxidative step and, in turn, the imino compound yields the c...

We have performed a density functional theory investigation on the structural and electronic properties of pristine and Nitrogen-doped TiO2 anatase nanoparticles as the adsorbents for removal and degradation of hydrazine molecules in the environment. We have presented the most stable adsorption configurations and examined the interaction of hydrazine molecule with these doped and undoped nanopa...

Proton nuclear magnetic resonance (NMR) spectroscopy is employed to characterize the kinetics of base-pair opening in a series of 9mer duplexes containing different single base mismatches. The imino protons from the different mismatched, as well as fully matched, duplexes are assigned from the imino-imino region in the WATERGATE NOESY spectra. The exchange kinetics of the imino protons are meas...
