Synthesis and in Vitro Antimicrobial Activity of Some Pyrazolyl-1-carboxamide Derivatives

open access: yesMolecules, 2011
A series of 3,5-disubstituted pyrazole-1-carboxamides were obtained by treatment of chalcones with semicarbazide hydrochloride in dioxane containing sodium acetate/acetic acid as a buffer solution.

Application of Computational Chemical Shift Prediction Techniques to the Cereoanhydride Structure Problem-Carboxylate Complications. [PDF]

open access: yes, 2017
Despite the vast array of techniques available to modern-day chemists, structural misassignments still occur. These misassignments are often only realized upon attempted synthesis, when the spectra of synthesized products do not match previously reported

Quantification of acetylated tubulin [PDF]

open access: yes, 2013
The acetylation/deacetylation of Lys40 of the α-subunit is an important posttranslational modification undergone by tubulin during the life of a cell. Many previous studies have addressed the physiological role of this acetylation process using various ...
