A novel scaffold for the construction of self-organised ionic liquids and ionic liquid crystals bearing both perfluorocarbon and hydrocarbon moieties has been developed. The phase behaviour and physical properties of these materials can be tuned as a function of chain length and fluorine content and significant structural elaboration is possible, giving a highly flexible system.

Recent studies have shown that combining kinase inhibitors has additive and synergistic effects. BRAFV600E and p38α have been extensively studied as potential therapeutic targets for a variety of diseases. In keeping with our interest in developing multi-targeted anticancer agents, a series of novel triaryl-imidazole-based analogues containing 3-aryl-1,2,4-oxadiazoles moiety (4a-h, Scaffold B) and their reaction intermediates aryl carboximidamides moiety (3a-h, Scaffold A) have been rationally designed, synthesized, and evaluated in vitro for their antiproliferative activity as dual p38α/BRAFV600E inhibitors. The results revealed that the presence of the carboximidamide moiety is required for activity, and the best activity correlates with the Ar = 1,2-benzodioxole (3e) ≥ 4-CH3O-C6H5-(3c) > 2-naphthyl (3h) > 4-Cl-C6H5 (3b). Ring closure of carboximidamide to 1,2,4-oxadiazole significantly reduces the activity. The results of docking study into p38α revealed higher binding affinities for compounds 3c, 3e, and 3h compared to the co-crystallized ligand, SB2. However, the docking study of compounds 3c and 3e into BRAFV600E revealed slightly lower affinities than vemurafenib.

Starting from the structure of previously reported 3-Br-isoxazoline-based covalent inhibitors of P. falciparum glyceraldehyde 3-phosphate dehydrogenase, and with the intent to improve their metabolic stability and antimalarial activity, we designed and synthesized a series of simplified analogues that are characterized by the insertion of the oxadiazole ring as a bioisosteric replacement for the metabolically labile ester/amide function. We then further replaced the oxadiazole ring with a series of five-membered heterocycles and finally combined the most promising structural features. All the new derivatives were tested in vitro for antimalarial as well as antileishmanial activity. We identified two very promising new lead compounds, endowed with submicromolar antileishmanial activity and nanomolar antiplasmodial activity, respectively, and a very high selectivity index with respect to mammalian cells.
