A Yb(OTf)3catalyzed [1,3]-rearrangement of 3-alkenyl oxindoles was achieved, affording a variety of multifunctional 3-ylideneoxindoles with good yields andZ/Eselectivities (64%-89% yield, 78?:?22->99?:?1Z/E). Importantly, an operationally simple, one-pot sequential catalytic synthesis of 3-ylideneoxindoles was also developed. Additionally, a cross [1,3]-rearrangement experiment and nonracemic transformation were also carried out, which indicated a concerted rearrangement mechanism of this methodology.

Sixteen new selenium-containing indole chalcone and diarylketone derivatives were synthesized and evaluated as tubulin polymerization inhibitors. Among them, compound 25b exhibited the most potent antiproliferative activities against six human cancer cell lines with IC50 values of 0.004-0.022 μM. A microtubule dynamics assay and an immunofluorescence assay confirmed that 25b could effectively inhibit tubulin polymerization (IC50 = 2.1 ± 0.27 μM). Further cellular mechanism studies revealed that 25b induced G2/M phase arrest, which was further evidenced by the decrease in the mitochondrial membrane potential (MMP).

A series of novel chalcone analogues were designed, synthesized and evaluated as anticancer agents. The results of antiproliferative activity tests showed that most of the analogues exhibited moderate to very good antiproliferative activities with GI50 values in the micromol to sub-micromol range. Especially compound 10a gave 0.026 μM to 0.035 μM GI50 for five cancer cell lines. The mechanistic studies including tubulin polymerization inhibition, disruption of microtubule dynamics and cell cycle arrest assay demonstrated that compound 10a could effectively inhibit in vitro cellular tubulin polymerization, interfere with the mitosis, resulting in a prolonged G2/M cell cycle arrest and ultimately lead to cell apoptosis of cancer cells. Taken together, these results suggested that 10a may became a promising lead compound for development of new anticancer drugs.
