A series of novel thiosemicarbazone analogs (4a–t, 6a–j) were synthesized and evaluated for their cytotoxic activities. The obtained results showed that thiochromanone-based thiosemicarbazones substituted primarily at the C-8 position exhibited higher cytotoxicity than the corresponding 1,1-dioxo-thiochromanone-, benzothiazepine-, and 1,1-dioxo-benzothiazepine-based analogs. Significantly, compound 4c (8-fluoro thiochromanone thiosemicarbazone) was found to be the most active and exhibited potent cytotoxicity against the MCF-7, SK-mel-2, and DU145 cancer cell lines, with IC50 values of 0.42, 0.58, and 0.43 μM, respectively. In addition, the mechanism of compound 4c induced MCF-7 cell apoptosis was preliminarily investigated through cell cycle, Annexin V-FITC/PI staining, and ROS assays, indicating that compound 4c may exert its anticancer property through ROS-mediated apoptosis.

By employing triethylamine as a catalyst, [3?+?2] coupling-elimination cascade of α,α-dicyanoolefins with quinone monoimines was realized. The reactions afforded various novel pterocarpen analogues with generally moderate yields (up to 75%). In addition, a plausible reaction mechanism was proposed.

2-(Indole-3-yl)-thiochroman-4-ones were synthesized via ionic liquid and tested for in vitro antifungal activity. The contribution of ionic liquid to Michael addition reaction is significant. Structures of all compounds are elucidated by 1H NMR, 13C NMR and HRMS. Most of these compounds showed better antifungal activity than fluconazole. The results suggest that 2-(indole-3-yl)-thiochroman-4-ones would be efficient antifungal agents.
