Synthesis of turbomicin-based alkaloids through infrared light-induced multicomponent reactions and assessment of their cytotoxic and antifungal bioactivity
elaborated compounds (> 103 Da) showed an antifungal effect against C. parapsilosis and C. neoformans at a concentration of 2.4 mM comparable to ketoconazole (22 vs. 20 mm). In contrast, its lower molecular weight homologous (< 500 Da) exhibited substantially the best cytotoxic effect against the growth of the colon adenocarcinoma cell lines SW620 and WS408 (IC50 = 12.56 ± 3.3 μmol and 13.9 ± 2.7 μmol)
accomplish C−Cπ bond construction reaction between π-excessive azaheteroaromatic and different carbonyl substrates supported on a bentonitic clay catalyst in solventless condition via a three-component condensation reaction. Preliminary studies show that the implementation of a domestic Flavor-Wave® oven fitted with a halogen heater lamp as a chemical reactor was as effective as the use of near IR light
