To explore the structure–activity relationships of thiosemicarbazones on African trypanosome: Trypanosoma brucei brucei, a series of thirty-five thiosemicarbazones (1–35) have been synthesized and characterized by their 1H NMR, 13C NMR, and FT-IR spectra. All compounds were tested for trypanocidal activity using the method “Lilit alamar blue”. The(More)
Cymbopogon citratus and Eucalyptus citriodora are widely used herbs/plants as a source of ethnomedicines in tropical regions of the world. In this work, we studied the anti-inflammatory and gastroprotective effects of C. citratus and E. citriodora essential oils on formol-induced edema, and acetic acid induced abdominal cramps in Wistar rats. To fully(More)
Thiosemicarbazones have become one of the promising compounds as new clinical candidates due to their wide spectrum of pharmaceutical activities. The wide range of their biological activities depends generally on their related aldehyde or ketone groups. Here, we report the pharmacological activities of some thiosemicarbazones synthesized in this work.(More)
Based on a line of evidence (logP, pKa, 1H-, and 13C-NMR, and molecular modeling studies), it appears that cocaine undergoes a hydrophobic collapse which may account for its unprecedented ADME properties, in particular, its exceptional capacity to cross biological membranes. Using molecular simulation techniques, the hypothesis of hydrophobic collapse(More)
This article reports data on four carbazones of piperitone: semicarbazone 1, thiosemicarbazone 2, 4-phenyl semicarbazone 3 and 4-phenyl thiosemicarbazone 4 prepared directly in situ from essential oil of Cymbopogon schoenantus, whose GC-FID and GC-MS analysis revealed piperitone as major component (68.20%). The structures of hemi-synthesized compounds were(More)
A concise series of aldehydes and ketones were reacted in a condensation reaction with 4-phenylthiosemicarbazide in order to assess the relative influence of the steric and electronic effects in the control of this reaction. While steric effects had a modest impact, electronic effects and in particular the mesomeric donating effect delivered by a phenyl(More)
The chemical contamination of food is among the main public health issues in developing countries. With a view to find new natural bioactive products against fungi responsible for chemical contamination of staple food such as maize, the antifungal activity tests of scopoletin extracted from different components of the cassava root produced in Benin were(More)
