An efficient synthetic method of medicinally important chalcone-derived heteroaromatics was proposed, which comprised of conjugate addition of ethyl acetoacetate to chalcones, followed by Mn-III/Co-II-catalyzed oxidative deacetylation. Paal-Knorr reactions of the resulting 1,4-dicarbonyl compounds containing various phenyl substituents produced the corresponding 2-carboethoxy-3,5-diphenyl furans, pyrroles, and thiophenes. The scope, mechanism, and electronic requirements for the phenyl substituents of chalcones in the key radical-medicated deacetylation reaction were fully elucidated. Antibacterial activities of the 21 chalcone-derived heteroaromatics were screened for Escherichia coli, Staphylococcus aureus, and Acinetobacter baumannii. The parent pyrrole 5 a showed most effective inhibition for E. coli and one third of the heteroaromatics exhibited significant inhibition for S. aureus at the concentration of 64 mu g/mL.

A family of ferrocene-based chiral PNP ligands is reported. These tridentate ligands were successfully applied in Mn- catalyzed asymmetric hydrogenation of ketones, giving high enantioselectivities (92%similar to 99% ee for aryl alkyl ketones) as well as high efficiencies (TON up to 2000). In additiondialkyl ketones could also be hydrogenated smoothly. Manganese intermediates that might be involved in the catalytic cycle were analyzed. DFT calculation was carried out to help understand the chiral induction model. The Mn/PNP catalyst could discriminate two groups with different steric properties by deformation of the phosphine moiety in the flexible 5-membered ring.

A convenient access toward novel fluoroionophores based on 1-(2-pyridyl)-4-styrylpyrazoles (PSPs) substituted at position 3 with donor or acceptor aryl groups is reported. The synthesis proceeds in two steps: the first one via Wittig olefination of the appropriate 4-formylpyrazole and then Mizoroki-Heck coupling to yield the desired products in an overall yield of up to 69%. Photophysical properties of products (4-styryl) and their intermediates (4-vinyl) were explored, finding that they have strong blue-light emission with high quantum yields (up to 66%) due to ICT phenomena. The 3-phenyl PSP was studied as a turn-off fluorescent probe in metal ion sensing, finding a high selectivity to Hg2+ (LOD = 3.1 x 10(-7)M) in a process that could be reversed with ethylenediamine. The sensing mechanism and binding mode of the ligand to Hg2+ were established by HRMS analysis and H-1 NMR titration tests.

In the field of catalysis, material scientists pay much attention to tuning the activity and chemoselectivity of metal nanoparticles. Herein, we design and successfully synthesize a series of Co NPs which show high performance on hydrogenation of nitroarenes with both activity and chemoselectivity. Co-0.15@C/PC preferentially activates the -C=O bond over -NO2 in water with ammonia borane (AB); however, when the hydrogen source is changes to hydrazine hydrate (HH), the results are the opposite. The Co-based catalyst exhibits exceptionally high catalytic activity (with a TOF value of 10512 h(-1), which is approximately 100 times than the akin catalysts) and chemo-selectivity for the hydrogenation of nitro compounds under mild conditions. Additionally, the catalyst can be separated easily by a magnet and shows prominent stabilit, which means that it can be reused for at least 10 cycles.

A series of novel (E)-4-oxo-2-crotonamide derivatives were designed and synthesized to find potent antituberculosis agents. All the target compounds were evaluated for their in vitro activity against Mycobacterium tuberculosis H(37)Rv(MTB). Results reveal that 4-phenyl moiety at part A and short methyl group at part C were found to be favorable. Most of the derivatives displayed promising activity against MTB with MIC ranging from 0.125 to 4 mu g/mL. Especially, compound IIIa16 was found to have the best activity with MIC of 0.125 mu g/mL against MTB and with MIC in the range of 0.05-0.48 mu g/mL against drug-resistant clinical MTB isolates.

Eight heteroleptic nickel(II) and copper(II) complexes of the type [M(L1-4)(nap)(2)] (1-8), where L1-4 = 2-(1-(4-substitutedphenyl)ethylidene)-hydrazinecarbothioamide, nap = naproxen, and M = Ni(II) or Cu(II), have been synthesized and characterized. UV-vis and EPR spectral studies showed distorted octahedral geometry around metal(II) ions. The cyclic voltammogram of complexes 1-8 displayed an irreversible one-electron transfer process in the cathodic region (E-pc = -0.66 to -1.43 V), and nickel(II) complexes 1-4 displayed an irreversible one-electron oxidation process in the anodic region (E-pa = 0.75 to 1.10 V). The obtained magnetic moment values (1.82-1.93 mu(B)) for copper(II) complexes 5-8 indicate distortion from octahedral geometry, which is further supported by EPR studies. The geometry of the complexes is retained in both solid and solution phases as evidenced from UV-vis and EPR studies. All the complexes showed stability for almost 72 h in biologically relevant solutions. The reducing ability of the copper(II) complexes in the presence of ascorbic acid was analyzed by UV-vis and cyclic voltammetry techniques, which indicates the reduction of the copper(II) to a copper(I) center, and possible interaction within the cells. An in vitro antiproliferative study revealed the nontoxic nature of complexes to normal human dermal fibroblast (NHDF) up to a concentration of 100 ng/mL. The antiproliferative activity of the complexes was tested against three cancerous (human breast adenocarcinoma (MCF-7), hepatoma (HepG2), and lung (A549)) cell lines using MTT reduction assay, which showed enhanced activity for complexes 4 and 8 containing the hydrophobic substituent. Apoptotic and cellular uptake studies showed that complex 8 is readily taken up by HepG2 cell lines and induces ROS-mediated mitochondrial and caspase-dependent apoptosis. In silico studies indicated hydrogen bonding, hydrophobic, and pi-pair (pi-pi, pi-sigma, and pi-cation) interactions between the complexes and EGFR/VEGFR2 kinase receptors.
