Dye-sensitized solar cells (DSSCs) have motivated many researchers to develop various sensitizers with tailored properties involving anchoring and ancillary ligands. Ancillary ligands carry favorable light-harvesting abilities and are therefore crucial in determining the overall power conversion efficiencies. The use of ancillary ligands having aliphatic chains and/or phi-extended aromatic units decreases charge recombination and permits the collection of a large fraction of sunlight. This review aims to provide insight into the relationship between ancillary ligand structure and DSSC properties, which can further guide the function-oriented design and synthesis of different sensitizers for DSSCs. This review outlines how the new and rapidly expanding class of chelating ancillary ligands bearing 2,2?-bipyridyl, 1,10-phenanthroline, carbene, dipyridylamine, pyridyl-benzimidazole, pyridyl-azolate, and other aromatic ligands provides a conduit for potentially enhancing the performance and stability of DSSCs. Finally, these classes of Ru polypyridyl complexes have gained increasing interest for feasible large-scale commercialization of DSSCs due to their more favorable light-harvesting abilities and long-term thermal and chemical stabilities compared with other conventional sensitizers. Therefore, the main idea is to inspire readers to explore new avenues in the design of new sensitizers for DSSCs based on different ancillary ligands.

Optimization is reported for biaryltriazoles as inhibitors of the tautomerase activity of human macrophage migration inhibitory factor (MIF), a proinflammatory cytokine associated with numerous inflammatory diseases and cancer. A combined approach was taken featuring organic synthesis, enzymatic assaying, crystallography, and modeling including free-energy perturbation (FEP) calculations. X-ray crystal structures for 3a and 3b bound to MIF are reported and provided a basis for the modeling efforts. The accommodation of the inhibitors in the binding site is striking with multiple hydrogen bonds and aryl-aryl interactions. Additional modeling encouraged pursuit of 5-phenoxyquinolinyl analogues, which led to the very potent compound 3s. Activity was further enhanced by addition of a fluorine atom adjacent to the phenolic hydroxyl group as in 3w, 3z, 3aa, and 3bb to strengthen a key hydrogen bond. It is also shown that physical properties of the compounds can be modulated by variation of solvent-exposed substituents. Several of the compounds are likely the most potent known MIF tautomerase inhibitors; the most active ones are more than 1000-fold more active than the well-studied (R)-ISO-1 and more than 200-fold more active than the chromen-4-one Orita-13.

The interactions of c-myc G-quadruplex with three carbazole derivatives were investigated by UV?Vis spectrophotometry, fluorescence, CD spectroscopy, and molecular modeling. The results showed that a combination of carbazole scaffold functionalized with ethyl, triazole and imidazole groups resulted in stabilization of the intramolecular G-quadruplex formed by the DNA sequence derived from the NHE III1 region of c-myc oncogene (Pu22). Binding to the G-quadruplex Pu22 resulted in the significant increase in fluorescence intensity of complexed ligands 1?3. All ligands were capable of interacting with G4 DNA with binding stoichiometry indicating that two ligand molecules bind to G-quadruplex with comparable affinity, which agrees with binding model of end-stacking on terminal G-tetrads.

A tandem approach for the regio- and stereoselective synthesis of oxazolo-fused pyrroloquinolines 3a-l via the reaction of o-alkynylaldehydes 1a-i with chiral amino alcohols 2a-c under mild reaction conditions is described. The possible participation of the pyridine ring in the regioselective formation of 5-exo-dig cyclized products was supported by the controlled experiments. The structures and stereochemistry of the products were confirmed by NOESY and X-ray crystallographic studies.

Small molecule organic semiconductors have well-defined structures and can be used in place of polymers which often show batch-to-batch variation. Many different electron-rich donor and electron-deficient acceptor units have been used to design materials with reduced HOMO-LUMO gaps and improved mobilities. Here we introduce a novel acceptor unit, 1-dodecyl-6-dodecoxynaphthyridine-2-one. This acceptor unit has been used in the synthesis of two novel compounds, with thiophene and 2,1,3-benzothiadiazole (BT) cores. The BT-containing compound shows a narrower HOMO-LUMO gap, broad solid-state absorption and has been applied to organic field-effect transistors, showing a mobility of 0.022 cm2 V?1 s?1 after optimisation of devices using self-assembled monolayers.

New fused pyrido-pyrimidine and naphthyridine cycles were synthesized and characterized using spectral analysis. Initially, 2-cyano-N-(1-phenylethylidene) acetohydrazide (2) was prepared from the reaction of cyanoacetic acid hydrazide (1) with acetophenone then cyclized to 4,6-diamino-2-oxo-1-((1- phenylethylidene)amino)-1,2-dihy-dropyridine-3-carbonitrile (3) by the action of malononitrile and triethyl amine in dioxin. Fused pyridopyrimidine cycles (4-6) were obtained from the reaction of compound 3 with formic acid, glacial acetic acid and propionic acid, respectively in the presence of POCl3 as a catalyst. The novel cycles (7-9) were synthesized from the cyclization reaction of compound 3 with benzoyl chloride, phenylisocyanate and phenylisothiocyanate in presence of pyridine. Naphthyridine cycles (10-13) were obtained by cyclization of compound 3 with some of aliphatic ketones namely; acetone, cyclohexanone, 2-butanone and 4-methyl-2-pentanone, respectively in presence of FeCl3 as catalyst. The antimicrobial activity of the synthesized derivatives was evaluated against several bacterial species as well as candida albicans. Docking study was also achieved to explore the binding affinity of the potent discovered hit (9) inside the binding pocket of glucosamine-6-phosphate synthase, a target enzyme for the antimicrobial agents.
