Palmer, Ian Arthur published the artcileNovel salicylic acid analogs induce a potent defense response in Arabidopsis, Application of 2-Hydroxy-4-(trifluoromethyl)benzoic acid, the publication is International Journal of Molecular Sciences (2019), 20(13), 3356, database is CAplus and MEDLINE.

The master regulator of salicylic acid (SA)-mediated plant defense, NPR1 (NONEXPRESSER OF PR GENES 1) and its paralogs NPR3 and NPR4, act as SA receptors. After the perception of a pathogen, plant cells produce SA in the chloroplast. In the presence of SA, NPR1 protein is reduced from oligomers to monomers, and translocated into the nucleus. Several of these analogs can induce SA-mediated defense and inhibit growth of Pseudomonas syringae in Arabidopsis. These analogs, when sprayed on Arabidopsis, can induce the accumulation of the master regulator of plant defense NPR1. In a yeast two-hybrid system, these analogs can strengthen the interactions among NPR proteins. We demonstrated that these analogs can induce the expression of the defense marker gene PR1. Furthermore, we hypothesized that these SA analogs could be potent tools against the citrus greening pathogen Candidatus liberibacter spp. In fact, our results suggest that the SA analogs we tested using Arabidopsis may also be effective for inducing a defense response in citrus. Several SA analogs consistently strengthened the interactions between citrus NPR1 and NPR3 proteins in a yeast two-hybrid system. In future assays, we plan to test whether these analogs avoid degradation by SA hydroxylases from plant pathogens. In future assays, we plan to test whether these analogs avoid degradation by SA hydroxylases from plant pathogens.

Gao, Peng published the artcileIBX-Promoted Oxidative Cyclization of N-Hydroxyalkyl Enamines: A Metal-Free Approach toward 2,3-Disubstituted Pyrroles and Pyridines, HPLC of Formula: 96-20-8, the publication is Journal of Organic Chemistry (2020), 85(12), 7939-7951, database is CAplus and MEDLINE.

An iodoxybenzoic acid-mediated selected oxidative cyclization of N-hydroxyalkyl enamines was developed. Through this strategy, a variety of 2,3-disubstituted pyrroles and pyridines were produced in good selectivity involving oxidation of alc., followed by condensation of aldehyde and α-C of enamines. Furthermore, this metal-free method has several advantages, including the use of environmentally friendly reagents, broad substrate scope, mild reaction conditions, and high efficiency.

Zhang, Jinping published the artcileBase-assisted activation of phenols in TiO₂ surface complex under visible light irradiation, Category: alcohols-buliding-blocks, the publication is Journal of Photochemistry and Photobiology, A: Chemistry (2022), 114005, database is CAplus.

Surface charge-transfer complex formed by TiO₂ and phenols has showed a great potential in visible-light photocatalysis. However, back electron transfer limits the charge transfer efficiency and the activation of phenols in surface complex. Herein, we disclosed the efficient activation of phenols in surface complex by introducing the base. Both homocoupling reactions and butylated hydroxytoluene-trapped experiments clearly demonstrated the generation of phenolic radicals from various lignin-derived substrates. The addition of base caused the blue-shifted absorption of surface complex, while increased the visible light-induced electron excitation from substrate to TiO₂. Vibrational spectra suggested that the interaction between phenolate and TiO₂ was stronger than the interaction between neutral phenol and TiO₂. This base-triggered strategy may be conducive to useful transformations or degradation of phenols via surface complex.

Guo, Ge published the artcileCatalytic depolymerization of Kraft lignin towards liquid fuels over bifunctional molybdenum oxide based supported catalyst, Formula: C9H12O, the publication is Fuel (2021), 121599, database is CAplus.

Catalytic depolymerization of Kraft lignin towards valuable liquid fuels and monomeric phenols has been a significant and extremely attractive target, but it remains a great challenge. Herein, we report a catalytic system consisted of bifunctional molybdenum oxide based supported catalyst for catalytic lignin hydroconversion into alkylated benzenes and phenols. In the meantime, the achieved yield of liquid product was 95% and petroleum ether extracted product was 65% at 300°C for 12 h over 20%MoO_x/ZIF-8@ZIF-67 catalyst. The calorific value was increased from 25.66 MJ/ Kg to 34.31 MJ/Kg. The characterization studies show the incorporation of MoOx species leads to the synergy between redox sites and acid sites. The product anal. and catalytic studies demonstrate its synergism to promote catalytic cleavage of C-O linkages via the coupled hydrodeoxygenation and alkylation reaction. The reasonable catalytic mechanism and redox cycle route of catalyst indicate that the cooperative catalytic system paves the way for high-efficiency waste lignin utilization.

Pei, Zhonghua published the artcileExploration of Pyrrolobenzodiazepine (PBD)-Dimers Containing Disulfide-Based Prodrugs as Payloads for Antibody-Drug Conjugates, Quality Control of 73303-88-5, the publication is Molecular Pharmaceutics (2018), 15(9), 3979-3996, database is CAplus and MEDLINE.

A number of cytotoxic pyrrolobenzodiazepine (PBD) monomers containing various disulfide-based prodrugs were evaluated for their ability to undergo activation (disulfide cleavage) in vitro in the presence of either glutathione (GSH) or cysteine (Cys). A good correlation was observed between in vitro GSH stability and in vitro cytotoxicity toward tumor cell lines. The prodrug-containing compounds were typically more potent against cells with relatively high intracellular GSH levels (e.g., KPL-4 cells). Several antibody-drug conjugates (ADCs) were subsequently constructed from PBD dimers that incorporated selected disulfide-based prodrugs. Such HER2 conjugates exhibited potent antiproliferation activity against KPL-4 cells in vitro in an antigen-dependent manner. However, the disulfide prodrugs contained in the majority of such entities were surprisingly unstable toward whole blood from various species. One HER2-targeting conjugate that contained a thiophenol-derived disulfide prodrug was an exception to this stability trend. It exhibited potent activity in a KPL-4 in vivo efficacy model that was approx. three-fold weaker than that displayed by the corresponding parent ADC. The same prodrug-containing conjugate demonstrated a three-fold improvement in mouse tolerability properties in vivo relative to the parent ADC, which did not contain the prodrug.

Tsai, Yan-Ting published the artcileSelective C_α Alcohol Oxidation of Lignin Substrates Featuring a β-O-4 Linkage by a Dinuclear Oxovanadium Catalyst via Two-Electron Redox Processes, SDS of cas: 70110-65-5, the publication is European Journal of Inorganic Chemistry (2019), 2019(43), 4637-4646, database is CAplus.

Developing highly efficient catalyst systems to transform lignin biomass into value-added chem. feedstocks is imperative for using lignin as renewable alternatives to fossil fuels. Recently, the pre-activated strategy involving the selective oxidation of C_α alc. of lignin substrates containing (β-O-4) linkage mode significantly increases the depolymerization efficiency of native aspen lignin from 10-20 to 60 weight-%. the authors reported the synthesis of a dinuclear oxovanadium complex 2 that is capable of selectively oxidizing the C_α alc. (80-100% selectivity) of various dimeric lignin substrates under a mild condition. Further study of catalytic mechanism revealed that two V=O motifs of complex 2 could serve as proton abstraction sites for both C_α and C_γ alc. of dimeric lignin substrates, resp. The dinuclear vanadium intermediate 4 demonstrates the ability to uptake two electrons resulting from the oxidation of C_α alc. and yields two corresponding mononuclear V^IV intermediate 5. The mononuclear V^IV intermediate 5 exhibits a characteristic 8-line EPR spectrum and possesses one unpaired electron determined by the Evans method. The established structure-reactivity relations will be able to shed light on the future directions for rational design of highly efficient catalysts for selective oxidation of lignin biomass.

The alcs. RNHCHR1(CH2)3OH (I; R = Pr, Me, PhCH2, R1 = H) were prepared from Cl(CH2)4OH and the corresponding amine; I (R = Me, R1 = 3-pyridyl) was prepared by condensation of Et nicotinate with butyrolactone to give dihydro-3-(3-pyridoyl)-2-(3H)-furanone, which was successively hydrolyzed, decarboxylated, and treated with NaBH3CN and MeNH2. Nitrosation of I with NaNO2 gave RN(N:O)CHR1(CH2)3OH which was oxidized with dicyclohexylcarbodiimide in DMSO to give RN(N:O)CHR1(CH2)2CHO. The aldehydes were mixtures of Z- and E-isomers.
