We report the synthesis and characterization of a series of cationic, neutral, and anionic dicopper(I) complexes featuring a p-mesityl ligand and a naphthyridine-derived PNNP expanded pincer ligand. Structural characterization showed that the protonation state of the dinucleating ligand has a pronounced effect on the bending and tilting of the mu-mesityl ligand. DFT calculations indicate that the varying orientations of the mu-mesityl ligand are inherent due to changes in electronic structure rather than crystal-packing effects. NBO analysis reveals how the interactions that contribute to the three-center two-electron bond between the mu-mesityl ligand and the dicopper core change for the various degrees of observed bending and tilting.

A one-step, transition-metal-free protocol, involving facile post-treatment, for the regioselective synthesis of 1,3-diazaheterocycle fused [1,2-a][1,8]naphthyridine derivatives (3) from 2-chloroquinoline-3-carbaldehydes (ClQuAlds) (1) and heterocyclic ketene anninals (HKAs) (2) was developed via a joint experimental computational approach. The computational prediction of the reactivity of two series of synthons was applied in the process of optimizing the reaction conditions, which relied on density functional theory (DFT) calculations together with concepts of frontier molecular orbital (FMO) theory. and quantitative structure reactivity relationship (QSRR) presumptions. The combined results enabled the proposal of a pre-synthetic prediction of global reactivity. The fully consistent results of the synthetic experiments with the in silico evaluation confirmed the rationality, effectiveness, and practicability of the new strategy. Notably, the joint method is not limited to the laboratory, but has applications ranging from routine to industry. This approach is likely to yield numerous insights to accelerate HKA-related synthetic chemistry that can be extended to numerous heterocycles. It thus opens up a novel entry towards rapidly investigating the reactivity of novel synthons with unique properties, a further step towards exploiting cascade reactions by avoiding the futile waste of time and resources.

As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. In an article, author is Bhattacharya, Labanya, once mentioned the application of 298-96-4, Name is Tetrazolium Red, molecular formula is C19H15ClN4.

The effect of structural modulation on a series of donor-acceptor (D-A) copolymers (1-7), comprising of thieno[3,2-b]thiophene (TT) donor and thiazole-flanked different bis-amide-functionalized acceptor units, has been explored. Structural functionalization has been performed by incorporating aromatic rings in the bis-amide-functionalized bipyrrolylidene-2,2 ‘(1H,1 ‘ H)-dione (BPD) (1) acceptor unit, and six D-A copolymers containing isoindigo (2), azaisoindigo (3), benzoisoindigo (4), benzoazaisoindigo (5), 1,5-naphthyridine-BPD (6), and 1,8-naphthyridine-BPD (7) as acceptor units are designed. Density functional theory has been employed to understand the impact of structural modulation on geometrical, optoelectronic, charge transport, and photovoltaic properties of the copolymers. The higher proportion of N-heteroatom in copolymers 3, 6, and 7 leads to low-lying highest occupied molecular orbital (lowest unoccupied molecular orbital) levels and thus improves their air stability and open-circuit voltage. The computed optical absorption in the visible range (602-754 nm) ensures that the studied compounds can efficiently harvest photon energy. The ratio of charge transfer rate (K-CT) and charge recombination rate (K-CR) at donor/PC61BM interfaces of structurally tuned copolymers are found to be similar to 10(7) to 10(22) times higher than 1/PC61BM. The maximum predicted power conversion efficiency by Scharber diagram could reach up to similar to 8% for 3, 6, and 7. The calculated results shed light on the fact that the structural modulation of bis-amide-functionalized D-A copolymers can efficaciously lead to enhanced air stability and photovoltaic performance.

A synthetic route to unsymmetrical 1,8-naphthyridine spacer based ligands is presented. Reaction of a 7-ethyldipyridyl-1,8-naphthyridine-2-carboxaldehyde intermediate with 2-aminophenol or 4,6-di-tert-butyl 2-aminophenol led to the formation of ligands, HL1 and HL2, respectively. Both combined two distinct binding sites: a dipyridyl and an iminophenol site linked through a 1,8-naphthyridine spacer. Treatment of HL1 with copper(II) triflate in the presence of triethylamine/H2O in acetonitrile afforded a tetranuclear complex (1(tox)center dot 2CH(3)CN). X-ray analysis revealed that the structure is constituted by the association of two identical dinuclear units in which the imine is oxidized to an amide group during the complexation. The coordination capabilities of the corresponding free amide ligands H2L1ox and H2L2ox, prepared by an independent route, were explored using copper(II) triflate in the presence of triethylamine/H2O. With the amide ligand, H2L1ox, a similar tetranuclear copper complex (1(tox)center dot 2DMF) compared to the one isolated after complexation with the imine ligand HL1 was formed, as evidenced by X-ray diffraction studies. In contrast, H2L2ox, where the amido phenol arm exhibits two additional tert-butyl groups, has allowed the formation of a trinuclear copper complex (2(triox)center dot H2O).

Cell cycle is an important part of cellular activities. The selective inhibition of cyclin-dependent kinases (CDK) activity in tumor cells can lead to continuous cell proliferation. Thirty-nine CDK8 inhibitors were systematically investigated on the basis of a three-dimensional quantitative structure-activity relationship (3D-QSAR). Models for comparative molecular field analysis (q(2)=0.64,r(2)=0.98) and comparative molecular similarity index analysis (q(2)=0.609,r(2)=0.952) were obtained. Contour maps illustrated that bioactivity of inhibitors is most affected by steric, electrostatic, hydrogen bond donor, and receptor interactions of molecular groups. Twenty new CDK8 inhibitors (DS01-DS20) were designed based on the contour maps. The results of ADME prediction illustrated that the designed compounds had potential druggability. The binding mode between a ligand and receptor was explored through molecular docking and molecular dynamics. Results revealed that the hydrogen bond interaction with residue LYS52 remarkably affected the activity of these compounds. Further analysis indicated that the introduction of fluorine to an amino naphthyridine ring of compound 28 contributes to the improvement of molecular activities. Pharmacophore-based virtual screening and Surflex-Sim in the ZINC database of 1,30,000 molecules demonstrated that 14 compounds with an indazole ring might be antitumor inhibitors. 3D-QSAR, molecular docking, molecular dynamics and pharmacophore results are consistent. These findings can be used as a reference for the design and discovery of new CDK8 inhibitors that can reduce design errors. Communicated by Ramaswamy H. Sarma
