Wu, Xue-ke;Zhang, Song;Liang, Dong-mei research published 《 Influence of external electric field on the molecular structure and electronic spectrum of 2-fluoro-5-bromopyridine molecule》, the research content is summarized as follows. The B3LYP method of d. functional theory (DFT) at 6 -311 + + g(3df, 3pd) level is used to calculate the geometrical parameters, dipole moments and total energies of the ground state of 2-fluoro 5-bromopyridine mol. under different external elec. fields in this paper. On the basis of this, the single-excitation CI (CIS) is used to study the influences of external elec. field on the excited wavelengths and oscillators of the first nine excited states. The results show that the bond lengths (5C-9Br, 3C-10F) will be greatest impact by X axial elec. field, and with the continue increase of elec. field, they may be the first to break. When the external elec. field F =0.005 a. u., the total energy is maximum, and the dipole moment is minimized. The LUMO energy levels are greatly influenced by external elec. field, but the HOMO energy levels are less affected by the external elec. field. The excited wavelength and oscillator are influenced by elec. field, but their changes with the elec. field are relatively complex.

Teresa;Pietzsch, Jens;Pietsch, Markus;Loeser, Reik research published 《 N^ε-Acryloyllysine Piperazides as Irreversible Inhibitors of Transglutaminase 2: Synthesis, Structure-Activity Relationships, and Pharmacokinetic Profiling》, the research content is summarized as follows. Transglutaminase 2 (TGase 2)-catalyzed transamidation represents an important post-translational mechanism for protein modification with implications in physiol. and pathophysiol. conditions, including fibrotic and neoplastic processes. Consequently, this enzyme is considered a promising target for the diagnosis of and therapy for these diseases. In this study, we report on the synthesis and kinetic characterization of N^ε-acryloyllysine piperazides as irreversible inhibitors of TGase 2. Systematic structural modifications on 54 new compounds were performed with a major focus on fluorine-bearing substituents due to the potential of such compounds to serve as radiotracer candidates for positron emission tomog. The determined inhibitory activities ranged from 100 to 10,000 M^-1 s^-1, which resulted in comprehensive structure-activity relationships. Structure-activity correlations using various substituent parameters accompanied by covalent docking studies provide an advanced understanding of the mol. recognition for this inhibitor class within the active site of TGase 2. Selectivity profiling of selected compounds for other transglutaminases demonstrated an excellent selectivity toward transglutaminase 2. Furthermore, an initial pharmacokinetic profiling of selected inhibitors was performed, including the assessment of potential membrane permeability and liver microsomal stability.

Wiles, Rebecca J.;Phelan, James P.;Molander, Gary A. research published 《 Metal-free defluorinative arylation of trifluoromethyl alkenes via photoredox catalysis》, the research content is summarized as follows. Literature methods to access gem-difluoroalkenes are largely limited to harsh, organometallic-based methods, and known photoredox-mediated processes are not amenable to aryl radical addition to trifluoromethyl alkenes. A metal-free, functional group-tolerant method for the preparation of benzylic gem-difluoroalkenes I (R = 4-CN, 3-OMe, 4-OMe, etc.) is described. Halogen atom abstraction from (hetero)aryl halides generates aryl radicals that underwent a defluorinative arylation of α-trifluoromethyl alkenes, tolerating electronically disparate aryl radicals and α-trifluoromethyl alkenes.

While hit 1() possessed attractive cell-based potency, it suffered from a significant right-shift in a whole blood assay, poor solubility, and poor pharmacokinetic properties. Through a physicochem. property-based approach, including a focus on lowering AlogP₉₈ via the strategic introduction of polar substitution, compound 13 was identified bearing a pyridyl oxetane core. Compound 13() demonstrated improved whole blood potency and solubility, and an improved pharmacokinetic profile resulting in a low predicted human dose.

Lithium tris-quinolinylaluminate complexes were prepared by transmetalation of quinolinyllithium compounds with EtAlCl₂; the electronic and steric effects of substitution of 2-quinolinyl groups for remote 8-quinolinyl groups were evaluated by single-crystal x-ray diffraction anal. and theor. calculations The effects of moving the donor N-atom from the 2-position in lithium (2-pyridyl)- and (2-quinolyl)aluminates to the more remote position in (8-quinolyl)aluminates have been investigated by solid-state structural and DFT computational studies of the new complexes [{EtAl(2-qy)₃}Li(μ-X)Li(THF)₃] (X = Cl/Br 62:38) [(1)Li(μ-X)Li(THF)₃], [{(EtAl(2-qy)₃)Li}₂(μ-Br)]^–Li(THF)₄⁺ [{1Li}₂(μ-Br)]^–Li(THF)₄⁺, [{EtAl(2-Me-8-qy)₃}Li] [(2)Li], [{Me₂Al(2-Me-8-qy)₂}Li(THF)] [(3a)Li(THF)], [{Me₂Al(6-Me-2-py)₂}Li(THF)₂] [(4)Li(THF)₂] and [{{EtAl(2-Me-8-qy)₂}₂O}(Li₂THF)] (5).
