anti-fungal compounds and it has been highly related to infections in catheterized patients. Few compounds are described as able to inhibit biofilm formation or to interfere with preformed biofilm of C. albicans. Here we report the in vitro evaluation of anti-biofilm activity on C. albicans ATCC 10231 of a series of new and already known amine and amide indolederivatives. Among the studied compounds, fifteen

Asymmetric synthesis and activity evaluation of tetrahydro-beta-spirooxindole compounds is reported in this paper. Cinchona alkaloid thiourea has been utilized as catalyst for the asymmetric synthesis of tetrahydro-beta-spirooxindoles, affording the desired products in moderate to good yields and with up to 94:6 er. Interestingly, the spirooxindoles exhibited moderate to good in vitro antitumor activity for A549 cells. Besides, the growth inhibitory activities of these selected compounds against normal lung cell CHL cells were further evaluated.
Copper/Iodine Co-catalyzed Oxygenative Transannulation of Tryptamines Enables Direct Synthesis of Donaxaridine and Its Derivatives
transannulation strategy using readily available tryptamines. Molecular oxygen and water are used as oxygen sources and provide direct access to the donaxaridine scaffold and its derivatives. This methodology is applied to the efficient synthesis of the natural products donaxaridine, chimonamidine, donaxanine, donaxarine, and aline in just one or two steps. The tryptamines, albeit with oxy-sensitive dialkyl N-H
