An efficient decarboxylative cycloaddition of 2,3-dioxopyrrolidines and ethynyl benzoxazinanones has been established by cooperative copper/amine catalysis. A copper-allenylidene complex and enolate intermediate, each catalytically generated from distinct substrates, underwent a cascade propargylation/hydroamination/aromatization process to construct a big library of cyclopenta[b]indole derivatives with good to excellent yields and excellent diastereoselectivity.

Strong-field ionization of complex molecules

Strong-field photoelectron momentum imaging of the prototypical biomolecule indole is disentangled in a combined experimental and computational approach. Experimentally, strong control over the molecules enables the acquisition of photoelectron momentum distributions in the molecular frame for a well-defined narrow range of incident intensities. A highly efficient semiclassical simulation setup based on the adiabatic tunneling theory quantitatively reproduces these results. Jointly, experiment and computations reveal holographic structures in the asymptotic momentum distributions, which are found to sensitively depend on the alignment of the molecular frame. We identify the essential molecular properties that shape the photoelectron wave packet in the first step of the ionization process and employ a quantum-chemically exact description of the cation during the subsequent continuum dynamics. The detailed modeling of the molecular ion, which accounts for its polarization by the laser electric field, enables the accurate description of the photoelectron dynamics in close vicinity of the molecule. Our approach provides full insight into the photoelectron’s dynamics in terms of semiclassical trajectories and aims at the simulation and unraveling of strong-field diffractive imaging of biomolecular systems on femtosecond timescales.

Design, synthesis and computational studies involving Indole-Coumarin hybrids as galectin-1 inhibitors

In continuation of our quest to develop non-carbohydrate galectin-1 inhibitors, we have designed and synthesized 20 indole-coumarin hybrids linked via chalcone. Compounds 6i and 7e were found to decrease galectin-1 levels significantly in galectin-1 enzyme assay at 20 mu M concentration. Binding affinity studies carried out by fluorescence spectroscopy revealed that 6i binds to galectin-1 with a binding constant (K-a) value of 5.4 x 10(5) M-1 while 7e was found to have a slightly higher affinity than 6i with K-a of 6.6 x 10(5) M-1. Molecular docking was carried out to ascertain the interaction between ligand and protein. To further gain structural insights into the binding of the compounds, 30 ns molecular dynamic simulations were carried out. The studies revealed that compound 7e was stable within the subsite C of galectin carbohydrate recognition domain while 6i fluctuated throughout the simulation. In addition, 7e maintained continuous interaction with Trp68 and His52, the two key amino acid residues are responsible for recognition of ligands within the active site. Furthermore, 7e displayed H-bond interactions with highly conserved amino acids within galectin-1 CRD, i.e., Arg48, Asn61 and Glu71. Free energy of binding evaluated by MM-GBSA calculations was also in accordance with experimental data. 7e was calculated to have binding energy of – 53.40 kcal/mole while 6i was found to have a value of – 45.63 kcal/mole.
