In previous work, we reported the in vitro antiprotozoal activity of bis(spiropyrazolone)cyclopropanes, easily synthesized from 4,4′-(arylmethylene)bis(1-phenyl-3-methyl-1H-pyrazol-5-ol) [26]. Thus, it is interesting to extend the activity study of 1H-pyrazole-5-ol and similar compounds ...
A comprehensive study was carried out to determine the chemical stability and antimicrobial activity of 6,6′-Diamino-1,1′,3,3′-tetramethyl-5,5′-(4-chlorobenzylidene)bis[pyrimidine-2,4(1H,3H)-dione]. Using the DFT approach, the quantum chemical descriptors recognized the title molecule as...
The 1H and 13C {1H} NMR spectra of this compound did not show any impurities; even the 19F NMR spectrum contained only the signals of product 2 (Figure S1). However, after crystallization from hot ethanol, a partial decomposition due to cleavage of the Ph2P(=O) moiety is observed, ...
