5-Substituted 2-benzylidene-1-tetralone analogues as A1 and/or A2A antagonists for the potential treatment of neurological conditions
(Elsevier, 2017)Adenosine A1 and A2A receptors are attracting great interest as drug targets for their role in cognitive and motor deficits, respectively. Antagonism of both these adenosine receptors may offer therapeutic benefits in ... -
6-Nitro-1-benzylquinolones exhibiting specific antitubercular activity
(Wiley, 2020)In this study, we synthesized novel nitro quinolone‐based compounds and tested them in vitro against a panel of Gram‐positive and Gram‐negative pathogens including Mycobacterium tuberculosis (MTB), Pseudomonas aeruginosa ... -
6-phenylpyridazin-3(2H)one as new corrosion inhibitor for C38 Steel in 1 M HCl
(ESG, 2017)The corrosion behavior of C38 steel in HCl solutions and its inhibition by 6-phenylpyridazin-3(2H)one (PPO) has been studied in different temperature using polarization and electrochemical impedance spectroscopy (EIS) ... -
68Ga-NOTA-functionalized ubiquicidin: cytotoxicity, biodistribution, radiation dosimetry, and first-in-human PET/CT imaging of infections
(Society of Nuclear Medicine and Molecular Imaging, 2018)Ubiquicidin is an antimicrobial peptide with great potential for nuclear imaging of infectious diseases, as its cationic-rich fragment TGRAKRRMQYNRR (UBI) has been functionalized with NOTA to allow complexation to 68Ga ... -
The 72-h WEBT microvariability observation of blazar S5 0716+714 in 2009
(EDP Sciences, 2013)Context. The international Whole Earth Blazar Telescope (WEBT) consortium planned and carried out three days of intensive micro-variability observations of S5 0716+714 from February 22, 2009 to February 25, 2009. This ... -
8-(3-phenylpropyl)-1,3,7-triethylxanthine is a synthetic caffeine substitute with stronger metabolic modulator activity
(Elsevier, 2018)Caffeine is one of the most worldwide consumed methylxanthines. It is well-known for its thermogenic and cell metabolism modulating effects. Based on methylxanthines' chemical structure, 8-(3-phenylpropyl)-1,3,7-triethylxanthine ... -
8-Aryl- and alkyloxycaffeine analogues as inhibitors of monoamine oxidase
(Elsevier, 2011)Recently it was reported that a series of 8-benzyloxycaffeine analogues are potent reversible inhibitors of human monoamine oxidase (MAO) A and B. In an attempt to discover additional C8 oxy substituents of caffeine that ... -
