Identification of polyphenols from antiviral Chamaecrista nictitans extract using high-resolution LC–ESI–MS/MS
(2014)
Chamaecrista nictitans (L) extract possesses antiviral properties; it acts against the herpes simplex virus, and this may be attributed to its constituent phenolics. Here, high-resolution LC–ESI–MS/MS is used to identify ...
From Ideality to Simplicity: A Robust and Affordable Hydrogen Reference Electrode
(2020-02-01)
In electrochemistry, the concept of a reference electrode is fundamental. Introductory courses might mention the standard hydrogen electrode (SHE), its working principle, and its theoretical design; however, chances are ...
Paraquat Behavior in Costa Rican Soils and Residues in Coffee
(1990)
The paraquat deactivation capacities of soils, from 20 coffee plantations, generally ranged from 100 to 500 mg of paraquat/kg of soil. Even when paraquat had been applied up to twice per year (1.2 kg ha-1 year) for 20 ...
Ethyl 5-[(ethoxycarbonyl)oxy]-5,5-diphenylpent-2- ynoate
(2019-11-12)
The title compound, C 22 H22 O 5, crystallizes with two molecules in the
asymmetric unit, one of which shows disorder of its ethyl acetate group over
two sets of sites in a 0.880 (2):0.120 (2) ratio. The C C distances ...
The Combined Use of Alphavirus Replicons and Pseudoinfectious Particles for the Discovery of Antivirals Derived from Natural Products
(2015)
Alphaviruses are a prominent class of reemergent pathogens due to their globally expanding ranges, potential for lethality, and possible use as bioweapons. The absence of effective treatments for alphaviruses highlights ...
Kinetik und Thermodynamik einer thermischen Umlagerung in der λ5-Phosphorinreihe. Die Umlagerung von 1-Acetoxy-λ5-phosphorin* in 6-Acetyl-1-oxo-1λ5-phospha-2,,4-cyclohexadien
Kinetic and Thermodynamic of a Thermal Rearrangement in the λ5-Phosphorin Series The Rearrangement of 1-Acetoxy-λ5-phosphorin into 6-Acetyl-1-oxo-1λ5-phospha-2,4-cyclohexadiene
(1974-03)
Beim Erhitzen von 1-Acetoxy-1-isopropoxy-2,4,6-triphenyl-λ5-phosphorin (1c) in 1,4-Dioxan entsteht 6c-Acetyl-1-isopropoxy-1r-oxo-2,4,6-triphenyl-1λ5-phospha-2,4-cyclohexadien (2c), das durch säurekatalysierte Epimerisierung ...
A new and efficient synthesis of (3E,8Z,11Z)-tetradeca-3,8,11-trienyl acetate, the major sex pheromone component of the tomato leafminer Tuta absoluta
(2018)
An efficient synthesis of (3E,8Z,11Z)-tetradeca-3,8,11-trienyl acetate, the major sex pheromone component of the tomato leafminer moth, Tuta absoluta, was accomplished. The synthesis started with but-3-yn-1-ol and gave an ...
