Moreland, D. E. published the artcileComparative effects of dichlobenil and its phenolic alteration products on photo- and oxidative phosphorylation, Name: 2,6-Dichloro-3-hydroxybenzonitrile, the publication is Pesticide Biochemistry and Physiology (1974), 4(3), 356-64, database is CAplus.

The effects of dichlobenil (2,6-dichlorobenzonitrile)(I) [1194-65-6] and its phenolic degradation products, 2,6-dichloro-3-hydroxybenzonitrile (II) [3336-34-3] and 2,6-dichloro-4-hydroxybenzonitrile (III) [3336-19-4] on electron transport and phosphorylation were studied in isolated spinach (Spinacia oleracea) chloroplasts and mung bean (Phaseolus aureus) mitochondria. II and III inhibited photoreduction, coupled phosphorylation, and cyclic phosphorylation in chloroplasts and acted as uncouplers of oxidative phosphorylation in mitochondria. II and III also decreased ATP in mung bean hypocotyls. In all assays only limited inhibition was caused by I, even at relatively high concentrations (1.0 mM).

Han, Xinya published the artcileBiological evaluation and SAR analysis of novel covalent inhibitors against fructose-1,6-bisphosphatase, Formula: C9H6N2O2, the publication is Bioorganic & Medicinal Chemistry (2020), 28(18), 115624, database is CAplus and MEDLINE.

Herein, a series of nitrostyrene derivatives I (R¹ = H, F, Me, etc.; R² = H, Cl, Me, etc.; R³ = H, Cl, Br, Me) were synthesized, and their inhibitory activities against Fructose-1,6-bisphosphatase (FBPase) were investigated in vitro. Most of the prepared compounds exhibit potent FBPase inhibition (IC₅₀ < 10μM). Specifically, when the substituents of F, Cl, OMe, CF₃, OH, CO₂H, or 2-nitrovinyl were installed at the R² (meta-) position of the benzene ring, the FBPase inhibitory activities of the resulting compounds increased 4.5-55 folds compared to those compounds with the same groups at the R¹ (para-) position. In addition, the preferred substituents at the R³ position were Cl or Br, thus compound I (R¹ = NO₂; R² = H; R³ = Cl) exhibited the most potent inhibitory activity (IC₅₀ = 0.15μM). The mol. docking and site-directed mutation suggest that C128 and N125 are essential for the binding of I (R¹ = NO₂; R² = H; R³ = Cl) and FBPase, which is consistent with the C128-N125-S123 allosteric inhibition mechanism. The reaction enthalpy calculations show that the order of the reactions of compounds with thiol groups at the R³ position is Cl > H > CH₃. CoMSIA anal. is consistent with proposed binding mode. The effect of compounds I (R¹ = 1,2,4-triazol-1-yl; R² = H; R³ = H) and I (R¹ = NO₂; R² = H; R³ = Cl) on glucose production in primary mouse hepatocytes were further evaluated, showing that the inhibition was 71% and 41% at 100μM, resp.

Wang, Jian-Shu published the artcileEx Situ Generation of Difluorodiazoethane (CF₂HCHN₂): Application in the Regioselective Synthesis of CF₂H-Containing Pyrazoles, HPLC of Formula: 5153-73-1, the publication is Organic Letters (2019), 21(21), 8751-8755, database is CAplus and MEDLINE.

A new method for the ex situ generation of difluorodiazoethane (CF₂HCHN₂) and a procedure for its efficient use in [3 + 2] cycloaddition with nitroolefins by the AcOH/O₂ catalyst system were developed by using a simple two-chamber system. The method provides a facile and straightforward access to a series of 4-substituted 5-difluoromethyl-3-nitro-1H-pyrazoles that are of interest in medicinal chem. Interestingly, the key factor for the success of this method is the efficient preparation of CF₂HCHN₂ by an ex situ process.

A novel series of 4-aminopiperidinyl-linked 3,5-disubstituted-1,2,6-thiadiazine-1,1-dione derivatives I [R = 3-CN, 4-NO₂, 2,4,6-(CH₃)₃, etc.; Ar = 1-naphthyl, 2,4-dichlorophenyl] were designed, synthesized, and evaluated for their in vitro anti-HIV activities in MT-4 cells based on the hybridization of the privileged fragments in DABO and DAPY-typed HIV-1 NNRTIs. Most of the target compounds showed weak inhibitory activity against WT HIV-1. In order to confirm the mode of action of the target compounds, representative compounds I (R = 4-NO₂; Ar = 1-naphthyl) and I (R = 4-NO₂; Ar = 2,4-dichlorophenyl) were selected to perform the HIV-1 RT inhibitory assay. In this assay, I (R = 4-NO₂; Ar = 1-naphthyl) and I (R = 4-NO₂; Ar = 2,4-dichlorophenyl) displayed good activity with IC₅₀ values of 3.15 and 1.52 μM, resp. Addnl., preliminary structure-activity relationships (SARs) anal. and mol. docking studies of newly synthesized compounds were also discussed.

Zou, Shuping published the artcileA integrated process for nitrilase-catalyzed asymmetric hydrolysis and easy biocatalyst recycling by introducing biocompatible biphasic system, COA of Formula: C8H6ClNO, the publication is Bioresource Technology (2021), 320(Part_B), 124392, database is CAplus and MEDLINE.

The whole-cell nitrilase-catalyzed asym. hydrolysis of nitriles is a green and efficient preparation approach for chiral carboxylic acids, but often suffers from toxicity and cell lysis from organic substrates. In this work, a novel integrated process for whole-cell nitrilase-catalyzed asym. hydrolysis was developed for the first time by introducing a biocompatible ionic liquid (IL)-based biphasic system. The whole-cell nitrilases displayed an outstanding stability and recyclability in the biphasic system and still retained > 85% activity even after 7 cycles reaction. A preparative-scale fed-batch hydrolysis of o-chloromandelonitrile to (R)-o-chloromandelic acid (R-CMA) was performed using the integrated process. The results revealed a yield of 91.3% and a space-time yield of 746.4 g·L^-1·d^-1, which are currently the highest reported values for R-CMA biosynthesis. The proposed integrated process avoids substrate inhibition, facilitates the reusability of whole-cell nitrilases, and thus shows great potential for the sustainable production of chiral carboxylic acids.

Xu, Han published the artcileSynthesis and herbicidal activities of novel 4-(3-trifluoromethylphenyl)-2H-pyridazin-3-one derivatives, HPLC of Formula: 612-13-5, the publication is Science China: Chemistry (2010), 53(1), 157-166, database is CAplus.

Three series of forty-nine novel 4-(3-trifluoromethylphenyl)-2H-pyridazin-3-one derivatives are designed, synthesized, and evaluated through a Spirodela polyrrhiza test and a greenhouse test. Some compounds show > 80% chlorophyll inhibition of Spirodela polyrrhiza at 10 μg/mL and exhibit some herbicidal activities against Digitaria adscendens in the preemergence treatment at a rate of 150 g/ha. Moreover, the study of the structure-activity relationship (SAR) suggests that the appropriate bulky substituent at the right position is critical for the bleaching and herbicidal activities, which may be useful for the future design of new compounds

Aiming at pollution from o-cyanobenzyl chloride and benzene, a green synthesis process was provided by using o-cyanotoluene as starting mol., after photochlorination, o-cyanobenzyl chloride directly reacted with a slight excess of tri-Et phosphate by esterification reaction without adding other organic solvents. The results showed that the optimal technol. condition was chlorination at 140°C, 1.0 of chlorination degree, using incandescent light bulb, esterification at 155°C for 4 h. The critical factor was controlling chlorination degree under 1.0, combination of photochlorination and esterification, in order to reduce pollution to environment.
