Regioselective Rh(I)-catalyzed sequential hydrosilylation toward the assembly of silicon-based peptidomimetic analogues

A highly regioselective Rh(I)-catalyzed hydrosilylation of enamides is presented. This mild protocol allows access to a wide variety of different arylsilanes with substitution at the beta-position of the enamide and functionalization on the alkyl chain tethered to the silane. This protocol is extended to include a sequential one-pot hydrosilylation. Using diphenylsilane as the appendage point, hydrosilylation of a protected allyl alcohol followed by hydrosilylation of an enamide generates a complex organosilane in one step. This highly convergent strategy to synthesize these functionalized systems now provides a way for the rapid assembly of a diverse collection of silane-based peptidomimetic analogues.

The interference of selected cytotoxic alkaloids with the cytoskeleton: An insight into their modes of action

Alkaloids, the largest group among the nitrogen-containing secondary metabolites of plants, usually interact with several molecular targets. In this study, we provide evidence that six cytotoxic alkaloids (sanguinarine, chelerythrine, chelidonine, noscapine, protopine, homoharringtonine), which are known to affect neuroreceptors, protein biosynthesis and nucleic acids, also interact with the cellular cytoskeleton, such as microtubules and actin filaments, as well. Sanguinarine, chelerythrine and chelidonine depolymerized the microtubule network in living cancer cells (Hela cells and human osteosarcoma U2OS cells) and inhibited tubulin polymerization in vitro with IC50 values of 48.41 ¡À 3.73, 206.39 ¡À 4.20 and 34.51 ¡À 9.47 muM, respectively. However, sanguinarine and chelerythrine did not arrest the cell cycle while 2.5 muM chelidonine arrested the cell cycle in the G2/M phase with 88.27% ¡À 0.99% of the cells in this phase. Noscapine and protopine apparently affected microtubule structures in living cells without affecting tubulin polymerization in vitro, which led to cell cycle arrest in the G2/M phase, promoting this cell population to 73.42% ? 8.31% and 54.35% ¡À 11.26% at a concentration of 80 muM and 250.9 muM, respectively. Homoharringtonine did not show any effects on microtubules and cell cycle, while the known microtubule-stabilizing agent paclitaxel was found to inhibit tubulin polymerization in the presence of MAPs in vitro with an IC50 value of 38.19 ¡À 3.33 muM. Concerning actin filaments, sanguinarine, chelerythrine and chelidonine exhibited a certain effect on the cellular actin filament network by reducing the mass of actin filaments. The interactions of these cytotoxic alkaloids with microtubules and actin filaments present new insights into their molecular modes of action.

Docking and quantum mechanic studies on cholinesterases and their inhibitors

Docking studies and density functional theory (DFT) calculations were made for 88 N-aryl derivatives and for some acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) residues. Based on this information, some compounds were synthesized and tested kinetically in vitro as AChE inhibitors. Finally, some chemical properties of the N-aryl derivatives were calculated: partition coefficient (pi) and molecular electrostatic potentials (MESPs) whereas their electronic effects (rho) were taken from the literature. The results showed that all compounds act inside the AChE gorge, making pi-pi interactions and hydrogen bonds with Trp86 and Ser203 and by high HOMO energies of Ser2003 and high LUMO energies of N-aryl derivatives. These theoretical calculations for AChE are in agreement with the experimental data, whereas such calculations for BChE do not show the same behavior which could be due to in spite of both cholinesterase enzymes displaying similar functional activities they do possess important structural differences at their catalystic sites.

o-Bromoarylsulfonylated amidines prepared either by acylation of amidine with o-bromoarylsulfonyl chloride or through the reaction of o-bromoarylsulfoamide with lactime ether underwent Cu(I)-catalyzed intramolecular cyclization to give 4H-1,2,4-benzothiadiazine-1,1-dioxides in good yield. By varying substituents on arylsulfonyl moieties, amidines, and lactime ethers, a small library of structurally diverse 4H-1,2,4- benzothiadiazine-1,1-dioxide derivatives was prepared.

Studies on poly(ester-urea-imide)s containing epoxy segment

Novel flame retardant poly(ester-urea-imide)s were prepared by diels?Alder (DA) polymerization reaction of various bisfuran derivatives (3a?e) containing amide linkages with brominated epoxy resin based bismaleimide (4). The so-called DA reaction was carried out by refluxing the mixture of both 3a?e and 4 monomers in THF solvent. The resultant DA adduct was formed which was treated with acetic anhydride at 135?C. The final products were in aromatized form and designated as poly(ester-urea-imide)s (PEUIs, 6a?e). These polymers were characterized by elemental analysis, number average molecular weight and thermogravimetric analysis. The glass and carbon fiber reinforced composites of such PEUIs were fabricated by ?in situ? polymerization process.

N-heterocyclic carbene-catalyzed annulation of alpha-cyano-1,4-diketones with ynals

In this paper, the first stereoselective annulation reaction between r-cyano-1,4-diketones and ynals, mediated by catalytic amounts of a triazolium salt precatalyst and cocatalytic amounts of a weak carboxylate base, is disclosed. The title transformation proceeds smoothly under mild reaction conditions and generates three contiguous stereogenic centers, one of which is a quaternary acetal carbon. This reaction tolerates a wide variety of electronically distinct substituents on both reaction partners and affords privileged bicyclic scaffolds in 61-90% isolated yields and with up to 20:1 diastereomeric preference.
