The alpha-methyl chalcone SD400 is a potent inhibitor of tubulin assembly and possesses potent anticancer activity. Various chalcone analogues were synthesized and evaluated for their cell growth inhibitory properties against the K562 human chronic myelogenous leukemia cell line (SD400, IC50 0.21 nM; combretastatin A4 CA4, IC50 2.0 nM). Cell cycle analysis by flow cytometry indicated that these agents are antimitotic (SD400, 83% of the cells are in G2/M phase; CA4 90%). They inhibit tubulin assembly at low concentration (SD400, IC50 0.46 muM; CA4, 0.10 muM) and compete with [3H]colchicine for binding to tubulin (8% [3H]colchicine remained bound to tubulin after competition with SD400 or CA4). Upon treatment with SD400, remarkable cell shape changes were elicited in HUVEC cells, consistent with vasculature damaging activity.

The prevalence of solvent effects has motivated developing quantitative kinetic, and theoretical assessments of solvent structures and their interactions with reaction intermediates.

A cationic ruthenium hydride complex, [(C6H6)(PCy3)(CO)RuH]+BF4- (1), with a phenol ligand was found to exhibit high catalytic activity for the hydrogenolysis of carbonyl compounds to yield the corresponding aliphatic products. The catalytic method showed exceptionally high chemoselectivity toward the carbonyl reduction over alkene hydrogenation. Kinetic and spectroscopic studies revealed a strong electronic influence of the phenol ligand on the catalyst activity. The Hammett plot of the hydrogenolysis of 4-methoxyacetophenone displayed two opposite linear slopes for the catalytic system 1/p-X-C6H4OH (rho = -3.3 for X = OMe, t-Bu, Et, and Me; rho = +1.5 for X = F, Cl, and CF3). A normal deuterium isotope effect was observed for the hydrogenolysis reaction catalyzed by 1/p-X-C6H4OH with an electron-releasing group (kH/kD = 1.7-2.5; X = OMe, Et), whereas an inverse isotope effect was measured for 1/p-X-C6H4OH with an electron-withdrawing group (kH/kD = 0.6-0.7; X = Cl, CF3). The empirical rate law was determined from the hydrogenolysis of 4-methoxyacetophenone: rate = kobsd[Ru][ketone][H2]-1 for the reaction catalyzed by 1/p-OMe-C6H4OH, and rate = kobsd[Ru][ketone][H2]0 for the reaction catalyzed by 1/p-CF3-C6H4OH. Catalytically relevant dinuclear ruthenium hydride and hydroxo complexes were synthesized, and their structures were established by X-ray crystallography. Two distinct mechanistic pathways are presented for the hydrogenolysis reaction on the basis of these kinetic and spectroscopic data. (Chemical Equation Presented).

An iodine-promoted fragment assembly strategy for the synthesis of fused heterocycles has been established. It provides an efficient route to construct pyrazolone-oxepine-pyrazoles from phenylhydrazines, aryl methyl ketones and acetoacetate esters. Notably, acetoacetate esters play two distinct pivotal roles in the five-component reaction by realizing the unique reactivities of methyl, methylene and carbonyl groups to construct 3-methyl-5-pyrazolone skeletons and by the reaction of methyl and carbonyl groups to form a C (sp3)-O bond.

Three-component reactions of phenylglyoxal monohydrate, phenols, and indoles were developed with the aid of acid-catalyst, which produced various densely substituted benzofurans with good to excellent yields. On the basis of this observation, a one-pot, step-wise reaction was developed by using methyl ketones instead of using phenylglyoxal component in I2/DMSO system. At last, three-component reaction offered a useful way to synthesize densely substituted benzofurans starting from simple and easily available substrates. The indole component can be replaced by some other nucleophiles, such as 1,2,4-trimethoxybenzene and thiophenol.

Biological studies of two series of 38 quinolinyl chalcones (4a-s and 5a-s) were investigated for their in vitro anti-HIV-1 and cytotoxic activities. Out of 38 compounds, seventeen compounds were observed as good anti-HIV-1 agents with EC50 values less than 20 muM. Compounds 4a, 4l, 4o, 5e, 5h, 5l, 5o, and 5r displayed potent anti-HIV-1 activity with EC50 values less than 5 muM. Among these, compound 5h emerged as the best anti-HIV-1 agent (EC50 = 1.1 muM). Compounds 4d, 4n, 4q, 4r, 4s, 5n, and 5r showed no toxicity in human lymphocytes. Bioassay results show that the type(s) and position(s) of the substituents seem to be critical for their cytotoxic and anti-HIV-1 activities.

(Chemical Equation Presented) A wide variety of aldehydes, ketones, and lactols undergo redox amination when allowed to react with 3-pyrroline in the presence of a mild Bronsted acid catalyst. This reaction utilizes the inherent reducing power of 3-pyrroline to perform the equivalent of a reductive amination to form alkyl pyrroles. In doing so, the reaction avoids stoichiometric reducing agents that are typically associated with reductive aminations. Moreover, the redox amination protocol allows access to alkyl pyrroles that cannot be made via standard reductive amination.
