A series of 1-methyl-1H-indole–pyrazoline hybrids were designed, synthesized, and biologically evaluated as potential tubulin polymerization inhibitors. Among them, compound e19 [5-(5-bromo-1-methyl-1H-indol-3-yl)-3-(3,4,5-trimethoxyphenyl)-4,5-dihydro-1H-pyrazole-1-carboxamide] showed the most potent inhibitory effect on tubulin assembly (IC50=2.12 μm) and in vitro growth inhibitory activity against a panel of four human cancer cell lines (IC50values of 0.21–0.31 μm). Further studies confirmed that compound e19 can induce HeLa cell apoptosis, cause cell-cycle arrest in G2/M phase, and disrupt the cellular microtubule network. These studies, along with molecular docking and 3D-QSAR modeling, provide an important basis for further optimization of compound e19 as a potential anticancer agent.

A series of novel compounds (6a-6v) containing 1-methylindol and 1-(4,5-dihydro-1H-pyrazol-1-yl) ethanone skeletons were designed, synthesized and biologically evaluated as potential tubulin polymerization inhibitors and anticancer agents. Among them, compound 6q showed the most potent tubulin polymerization inhibitory activity (IC50 = 1.98 mM) and in vitro growth inhibitory activity against A549, MCF-7 and HepG2 cell lines, with IC50 values of 0.15 mM, 0.17 mM, and 0.25 mM respectively, comparable to the positive control. Furthermore, compound 6q was a potent inducer of apoptosis in A549 cells and it had typical cellular effects for microtubule interacting agents, causing arrest of the cell cycle in the G2/M phase. Confocal microscopy assay and molecular docking results further demonstrated that 6q could bind tightly to the colchicine site of tubulin and act as an anti-tubulin agent. These studies, along with 3D-QSAR modeling provided an important basis for further optimization of compound 6q as a potential anticancer agent.

Tolerant: By using Pd(OAc)2/PCy3 as a catalyst, both electron-rich aromatic heterocycles and electron-deficient fluorobenzenes undergo the dehydrogenative cross-coupling with (hetero)aryl ethyl ketones in good yields. A broad range of functional groups is tolerated, thus providing a general method for the facile syntheses of chalcones or heterocyclic chalcone analogues. Furthermore, dialkyl ketones can also participate in this transformation. Copyright

A novel entry to functionalized benzofurans and indoles from furans in moderate to good yields has been developed. This protocol involves palladium(0)-catalyzed dearomatizing intramolecular arylation of the furan ring, formation of a π-allylic palladium complex, furan ring opening, and a β-hydride elimination sequence.
