The reaction of 1-butylimidazole (1a) with aryl/alkoxy halides (2a–h) using a microwave solvent-free approach delivered imidazolium-based ILs (3a–h) in good yield. Some of them showed promising antibacterial and antifungal activities.

Background: Many compounds containing a five-membered heterocyclic ring display exceptional chemical properties and versatile biological activities. Objective: The objective of the present study was the desire to prepare the 5-substituted 2-amino-1,3,4-oxadiazole and 2-amino-1,3,4-thiadiazole derivatives and evaluate their potential anticancer, antibacterial and antifungal activities. Methods: Twenty-seven derivatives were synthesized by iodine-mediated cyclization of semicarbazones or thiosemicarbazones obtained from condensation of semicarbazide or thiosemicarbazide and aldehydes. The structures were confirmed by 1H-NMR, 13C-NMR and MS spectra. The antibacterial and antifungal activities were evaluated by diffusion method and the anticancer activities were evaluated by MTT assay. Results: Twenty-seven derivatives have been synthesized in moderate to good yields. A number of derivatives exhibited potential antibacterial, antifungal and anticancer activities. Conclusion: Compounds (1b, 1e and 1g) showed antibacterial activity against Streptococcus faecalis, MSSA and MRSA with MIC ranging between 4 to 64 µg/mL. Compound (2g) showed antifungal activity against Candida albicans (8 µg/mL) and Aspergillus niger (64 µg/mL). Compound (1o) exhibited high cytotoxic activity against HepG2 cell line (IC50 value 8.6 µM), which is comparable to the activity of paclitaxel, and is non-toxic on LLC-PK1 normal cell line. The structure activity relationship and molecular docking study of the synthesized compounds are also reported.

2,3,5,6-Tetrasubstituted-4-aryl-1-(6-ethoxybenzothiazol-2-yl)-1,4-dihydropyridines were synthesized by the reaction of 2-amino-6-ethoxybenzothiazole, an aromatic aldehyde and an active methylene compound in methanol by conventional or microwave irradiation method (solvent-free or with solid support). All compounds were tested for antibacterial and antifungal activities and the results were compared with standard drugs. Their acaricidal and antifeedant activities were also tested.

The chemical composition of the essential oil from flowers of Eringium triquetrum Vahl. collected in Sicily was evaluated by GC and GC-MS. The main components were pulegone (50.6%), piperitenone (30.5%) and menthone (7.0%). Comparison of this oil with other studied oils of Eringium species is discussed. The oil showed good antibacterial and antifungal activities against some microorganisms that infest historical art works.
