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.

Fultariya, Chirag R.;Harsora, Jalpa P. research published 《 Synthesis, antimicrobial activity and cytotoxicity of 2-substituted benzimidazole incorporated with thiazole》, the research content is summarized as follows. Two new series 2-(2-(1-(1-methyl-1H-benzo[d]imidazol-2-yl)ethylidene)hydrazinyl)-4-(aryl)thiazoles I (R = H, 4-CH₃, 2-Cl, etc.) and 2-(2-(1-(1-methyl-1H-benzo[d]imidazol-2-yl)ethyl)hydrazinyl)-4-(aryl)thiazoles II (R =H, 4-CH₃, 2-Cl, etc.) encompassing benzimidazole incorporated with thiazole have been synthesized using rational approach. These thiazole derivatives I have been reduced at the site of formation of Schiff base (>CH = N0) to obtain final compounds II. Compounds I and II have been screened for their in vitro antibacterial and antifungal actions against four strains each. Among the screened compounds, I (R = 2-Cl, 4-Cl, 4-Br, 4-F, 2,4-diCl, 2,4-diF) and II (R = 2-Cl, 4-Cl, 4-Br, 2,4-diF) have emerged as highly effective antibacterial agents, while compounds I (R = 2-Cl, 4-Cl, 4-Br, 2,4-diF) and II (R = 2,4-diF) have come out as most potent antifungal mols. Comparison of outcomes of antibacterial and antifungal screening of compounds I and II directed that antimicrobial potential of unreduced derivatives I is higher than reduced derivatives II. SAR study reveals that presence of halogen (-F, -Cl, -Br) substituents is accountable for significant antimicrobial potential. Also the results of preliminary MTT cytotoxicity assay on HeLa cells indicates that antimicrobial activity of I (R = 4-Cl, 4-Br, 4-F, 2,4-diCl, 2,4-diF) and II (R = 4-Cl, 4-Br, 2,4-diF) is accompanied by low extent of cytotoxic concentrations

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.

Fu, Haigen;Lam, Heather;Emmanuel, Megan A.;Kim, Ji Hye;Sandoval, Braddock A.;Hyster, Todd K. research published 《 Ground-State Electron Transfer as an Initiation Mechanism for Biocatalytic C-C Bond Forming Reactions》, the research content is summarized as follows. The development of non-natural reaction mechanisms is an attractive strategy for expanding the synthetic capabilities of substrate promiscuous enzymes. Here, the authors report an “ene”-reductase catalyzed asym. hydroalkylation of olefins using α-bromoketones as radical precursors. Radical initiation occurs via ground-state electron transfer from the flavin cofactor located within the enzyme active site, an underrepresented mechanism in flavin biocatalysis. Four rounds of site saturation mutagenesis were used to access a variant of the “ene”-reductase nicotinamide-dependent cyclohexanone reductase (NCR) from Zymomonas mobiles capable of catalyzing a cyclization to furnish β-chiral cyclopentanones with high levels of enantioselectivity. Addnl., wild-type NCR can catalyze intermol. couplings with precise stereochem. control over the radical termination step. This report highlights the utility for ground-state electron transfers to enable non-natural biocatalytic C-C bond forming reactions.
