Gong, Ming;Huang, Mengmeng;Li, Yabo;Zhang, Jianye;Kim, Jung Keun;Kim, Jong Seung;Wu, Yangjie research published 《 Harnessing visible-light energy for unbiased organic photoelectrocatalysis: synthesis of N-bearing fused rings》, the research content is summarized as follows. In this research, the conversion of visible light to elec. energy and C-H activation by the synergistic catalytic effect of visible-light and photoelec. current is reported. An atom-economical and environment-friendly self-biasing interfacial photo-electrocatalytic method for cascade C-H activation/cyclization is provided to construct N-containing fused ring compounds using an m-BiVO₄ film as a photoanode. There are obvious advantages of this transformation due to no external bias and a small overpotential, saving elec. energy and avoiding excessive oxidation of malononitrile to achieve better chem. reactivity and selectivity. Meanwhile, the recovered photoanode could be used more than ten times.

Gregory, Carolyn;Silva, Weslley G. D. P.;van Wijngaarden, Jennifer research published 《 Rotational spectrum and quantum chemical calculations of methyl cyanoacetate: A compound of potential astrochemical interest》, the research content is summarized as follows. The rotational spectrum of Me cyanoacetate (H₃CO(CO)CH₂CN) was investigated for the first time using Fourier transform microwave spectroscopy in the 6-19 GHz range. The observed spectral pattern is that of a single, dominant conformer and reveals both ¹⁴N quadrupole hyperfine structure and characteristic A/E splittings due to the Me internal rotor. The rotational constants determined from anal. of the complex spectral pattern confirm that the observed spectrum is that of the lowest energy conformer of Me cyanoacetate predicted at the B3LYP-D3(BJ) and MP2 levels of theory using the aug-cc-pVTZ basis set. This global min. corresponds to a geometry which orients the C-O-C=O and C-C-C=O dihedral angles in syn and near anti arrangements, resp. and is governed by a balance of stabilizing orbital interactions and destabilizing steric effects identified using non-covalent interaction and natural bond orbital analyses.

Fujii, Takumi;Ito, Len;Watanabe, Shuhei;Yamamoto, Hideki research published 《 An alternative predictor of eye irritation that utilizes potential parameters of the human corneal epithelium model calculated based on Hansen solubility parameters》, the research content is summarized as follows. Eye irritation predictions are very important in the development of cosmetics and pharmaceuticals. For animal protection, alternative tests are being developed to replace the Draize test, which involves the use of rabbits to test eye irritation. The Vitrigel-eye irritancy test (Vitrigel-EIT), is one such alternative. As a preliminary study, we evaluated if Hansen solubility parameter (HSP) values can be used to predict Vitrigel-EIT results. An Hansen sphere was created based on the HSP values and Vitrigel-EIT results from 61 substances. Substances inside and outside of the sphere were designated as dangerous and safe substances, resp. The safety of each test substance was predicted by comparing the center point (Ro) of the sphere with the relative energy difference, i.e., the ratio of each test substance (Ra). The accuracy, false negativity, and false positivity of the “irritant” and “nonirritant” designations, as determined by the Vitrigel-EIT results and Hansen sphere, were 91.8% (56/61), 2.3% (1/43), and 22.2% (4/18), resp. These results indicated that HSP values can be used to predict Vitrigel-EIT results with high reproducibility, and thus are useful for evaluating the safety of substances.

This study aimed to synthesize quinolinone derivatives and investigate their cytotoxic activity.

Gehlen, Marcelo H.;Foltran, Larissa S.;Kienle, Daniel F.;Schwartz, Daniel K. research published 《 Single-Molecule Observations Provide Mechanistic Insights into Bimolecular Knoevenagel Amino Catalysis》, the research content is summarized as follows. While single-mol. (SM) methods have provided new insights to various catalytic processes, bimol. reactions have been particularly challenging to study. Here, the fluorogenic Knoevenagel condensation of an aromatic aldehyde with Me cyanoacetate promoted by surface-immobilized piperazine is quant. characterized using super-resolution fluorescence imaging and stochastic anal. using hidden Markov modeling (HMM). Notably, the SM results suggest that the reaction follows the iminium intermediate pathway before the formation of a fluorescent product with intramol. charge-transfer character. Moreover, the overall process is limited by the turnover rate of the catalyst, which is involved in multiple steps along the reaction coordinate.
