Two new series of conjugated arylethenyl-1,3,4-oxadiazolyl-1,2,4-oxadiazoles were obtained and spectroscopically characterized in terms of UV-Vis absorption, fluorescence and interaction with CT-DNA and Human Serum Albumin (HSA) biomolecules. Phenyl- and 1-naphthyl-bearing examples were analysed, and the spectroscopic properties of its substitution series were compared, showing extensive conjugation in all compounds and absorption differences due to both the aryl-ethenyl subunit and substituted phenyl/phenylene at the 1,2,4-oxadiazole side. Strong binding interactions of the obtained compounds with CT-DNA and moderate HSA-association capability were observed spectroscopically, and further docking studies were performed. This journal is

This article describes the synthesis, characterization and DNA-binding assays of a series of oxadiazoles derived from (E)-3-ferrocenylacrylic acid. The compounds were obtained in satisfactory yields and characterized by NMR and high resolution mass spectrometry analysis. Additionally, the X-Ray characterization of compound 8a was investigated. A series of ferrocenylethenyl-substituted 1,3,4-oxadiazolyl-1,2,4-oxadiazoles was prepared and studied by UV-visible and electrochemical techniques. The characteristic signals of the redox-active ferrocene/ferrocenium couple were monitored, which allowed verification of the influence of electron-withdrawing oxadiazole heterocycles and their dependence on the 1,2,4-oxadiazole substituent. Also, DNA-binding experiments were performed by UV-vis and emission titrations with ct-DNA.

Malaria, caused by several Plasmodium species, is the major life-threatening parasitic infection worldwide. Due to the parasite resistance to quinoline based drugs, the search for antimalarial agents is necessary. Here, we report the structural design, sy

We recently showed that oxadiazoles have anti-Trypanosoma cruzi activity at micromolar concentrations. These compounds are easy to synthesize and show a number of clear and interpretable structure-activity relationships (SAR), features that make them attr

Research in recent years has demonstrated that the Trypanosoma cruzi cysteine protease cruzain (TCC) is a valid chemotherapeutic target, since inhibitors of this protease affect the pathology appropriately. By exploring the N-acylhydrazones (NAH) as privi
