- Exploring 5-nitrofuran derivatives against nosocomial pathogens: Synthesis, antimicrobial activity and chemometric analysis
-
The burden of nosocomial or health care-associated infection (HCAI) is increasing worldwide. According to the World Health Organization (WHO), it is several fold higher in low- and middle-income countries. Considering the multidrug-resistant infections, t

- 5-Nitro-2-furfuriliden derivatives as potential anti-Trypanosoma cruzi agents: Design, synthesis, bioactivity evaluation, cytotoxicity and exploratory data analysis
-
The anti-Trypanosoma cruzi activity of 5-nitro-2-furfuriliden derivatives as well as the cytotoxicity of these compounds on J774 macrophages cell line and FN1 human fibroblast cells were investigated in this study. The most active compounds of series I and II were 4-butyl-[N′-(5-nitrofuran-2-yl) methylene] benzidrazide (3g; IC50 = 1.05 μM ± 0.07) and 3-acetyl-5-(4-butylphenyl)-2-(5-nitrofuran-2-yl)-2,3-dihydro,1,3,4-oxadiazole (4g; IC50 = 8.27 μM ± 0.42), respectively. Also, compound 3g was more active than the standard drugs, benznidazole (IC50 = 22.69 μM ± 1.96) and nifurtimox (IC50 = 3.78 μM ± 0.10). Regarding the cytotoxicity assay, the 3g compound presented IC 50 value of 28.05 μM (SI = 26.71) against J774 cells. For the FN1 fibroblast assay, 3g showed IC50 value of 98 μM (SI = 93.33). On the other hand, compound 4g presented a cytotoxicity value on J774 cells higher than 400 μM (SI >48), and for the FN1 cells its IC50 value was 186 μM (SI = 22.49). Moreover, an exploratory data analysis, which comprises hierarchical cluster (HCA) and principal component analysis (PCA), was carried out and the findings were complementary. The molecular properties that most influenced the compounds' grouping were C log P and total dipole moment, pointing out the need of a lipophilic/hydrophilic balance in the designing of novel potential anti-T. cruzi molecules.

- Synthesis and biological activity of nifuroxazide and analogs
-
Nifuroxazide and thirteen analogs were synthesized from substituted benzoic acids and minimal inhibitory concentrations were determined using the serial dilution tests, in three sequential steps. Nifuroxazide and chloramphenicol were used as reference standards. The tests were performed in TSB against the standard bacterial strain of Staphylococcus aureus ATCC 25923.
