Pterocarpans are derivatives of isoflavonoids, found in many species of the family Fabaceae. Sophora flavescens Aiton is a promising traditional Asian medicinal plant. Plant cell suspension cultures represent an excellent source for the production of valuable secondary metabolites. Herein, we found that methyl jasmonate (MJ) elicited the activation of pterocarpan biosynthetic genes in cell suspension cultures of S. flavescens and enhanced the accumulation of pterocarpans, producing mainly trifolirhizin, trifolirhizin malonate, and maackiain. MJ application stimulated the expression of structural genes (PAL, C4H, 4CL, CHS, CHR, CHI, IFS, I3’H, and IFR) of the pterocarpan biosynthetic pathway. In addition, the co-treatment of MJ and methyl-beta-cyclodextrin (Me beta CD) as a solubilizer exhibited a synergistic effect on the activation of the pterocarpan biosynthetic genes. The maximum level of total pterocarpan production (37.2 mg/g dry weight (DW)) was obtained on day 17 after the application of 50 mu M MJ on cells. We also found that the combined treatment of cells for seven days with MJ and Me beta CD synergistically induced the pterocarpan production (trifolirhizin, trifolirhizin malonate, and maackiain) in the cells (58 mg/g DW) and culture medium (222.7 mg/L). Noteworthy, the co-treatment only stimulated the elevated extracellular production of maackiain in the culture medium, indicating its extracellular secretion; however, its glycosides (trifolirhizin and trifolirhizin malonate) were not detected in any significant amounts in the culture medium. This work provides new strategies for the pterocarpan production in plant cell suspension cultures, and shows Me beta CD to be an effective solubilizer for the extracellular production of maackiain in the cell cultures of S. flavescens.

A redox-active iminoquinone motif connected with pi-delocalized pyrene core has been reported that can perform efficient two-electron oxidation of a class of substrates. The design of the molecule was inspired by the organic redox cofactor topaquinone (TPQ), which executes amine oxidation in the enzyme, copper amine oxidase. Easy oxidation of both primary and secondary alcohols happened in the presence of catalytic KOtBu, which could reduce the ligand backbone to its iminosemiquinonate form under photoinduced conditions. Moreover, this easy oxidation of alcohols under aerobic condition could be elegantly extended to multi-component, one-pot coupling for the synthesis of quinoline and pyrimidine. This organocatalytic approach is very mild (70 degrees C, 8 h) compared to a multitude of transition-metal catalysts that have been used to prepare these heterocycles. A detailed mechanistic study proves the intermediacy of the iminosemiquinonate-type radical and a critical hydrogen atom transfer step to be involved in the dehydrogenation reaction.

Single-atom photocatalysis as an important organic transformation strategy has received increasing attention, with the performances largely depending on the design of catalysts. This protocol involves initially the fabrication of a single-atom photocatalyst Ni/TiO2 for the visible-light-induced site-selective sulfonation of enamides to give amidosulfones with 36 examples up to 99% yield. The experimental results show that this single-atom photocatalyst Ni/TiO2 can achieve site-selective sulfonation of enamide to construct alpha-amidosulfones and beta-propionamidosulfones under visible light. Importantly, such a single-atom photocatalysis-based synthesis system exhibits favorable recyclability, high turnover number (up to 18 963), excellent tolerance of functional groups, and can be easily scaled up with good efficiency.

Computed Properties of C15H12O. The Name is Chalcone. Through research, I have a further understanding and discovery of 94-41-7.

An efficient and sustainable protocol for the hydration of alkynes has been developed under metal/acid/catalyst/ ligand-free conditions in a water/ethyl lactate mixture. The hydrogen-bond network in the ethyl lactate and water mixture plays a crucial and decisive role in activating the alkynes for hydration to afford the corresponding methyl ketones. This strategy gives the Markovnikov (ketone) addition product selectively over other possible products. The essential role of hydrogen bonding has been confirmed by experimental and theoretical techniques. A probable mechanism has been suggested by various control tests. The efficacy of the method has been further explored for the competent production of value-added alpha,beta-unsaturated carbonyl compounds through the reaction of aldehydes with alkynes as ketonic surrogates. The environmentally benign hydration method takes place under mild conditions, has broad functional-group compatibility, and uses the ethyl lactate/water (1:3) medium as a green alternative in the absence of any hazardous, harmful, or expensive substances.

This Letter describes the chemical optimization of a new series of muscarinic acetylcholine receptor subtype 1 (MO positive allosteric modulators (PAMs) based on novel tricyclic triazolo- and imidazopyridine lactam cores, devoid of M-1 agonism, e.g., no M-1 ago-PAM activity, in high expressing recombinant cell lines. While all the new tricyclic congeners afforded excellent rat pharmacokinetic (PK) properties (CLp < 8 mL/min/kg and t(1/2) > 5 h), regioisomeric triazolopyridine analogues were uniformly not CNS penetrant (K-p < 0.05), despite a lack of hydrogen bond donors. However, removal of a single nitrogen atom to afford imidazopyridine derivatives proved to retain the excellent rat PK and provide high CNS penetration (K-p > 2), despite inclusion of a basic nitrogen. Moreover, 24c was devoid of M-1 agonism in high expressing recombinant cell lines and did not induce cholinergic seizures in vivo in mice. Interestingly, all of the new M-1 PAMs across the diverse tricyclic heterocyclic cores possessed equivalent CNS MPO scores (>4.5), highlighting the value of both medicinal chemist’s eye and experimental data, e.g., not sole reliance (or decision bias) on in silico calculated properties, for parameters as complex as CNS penetration.

Background: With respect to the increase in the average life expectancy, Alzheimer Disease (AD), the most common form of age-related dementia, has become a major threat to the population over the age of 65 during the past several decades. The majority of AD treatments are focused on cholinergic and amyloid hypotheses. Objective: In this study, three series of diphenyl-2-(2-(4-substitutedpiperazin-l-yl)ethyl)pyridazin-3(2H)-one derivatives were designed, synthesized and investigated for their ability to inhibit both cholinesterase enzymes and amyloid-beta aggregation. Method: The inhibitory activities of the synthesized compounds on AChE (from electric eel) and BChE (from equine serum) were determined by the modified Ellman’s method. The reported thioflavin T-based fluorometric assay was performed to investigate the effect of the selected compounds on the aggregation of A beta(1-42). The cytotoxic effect of the compounds (4g, 11g and 18g) was monitored in 3T3 cell lines to gain insight into therapeutic potential of the compounds by using MTT assay. The crystal structures of the AChE (1EVE) and BChE (1POI) enzymes were retrieved from the RCSB Protein Data Bank and Molecular Operating Environment (MOE) software was used for molecular docking of the ligands. Results: Among the tested compounds, 5,6-diphenyl derivative 18g was identified as the most potent and selective AChE inhibitor (IC50 = 1.75 mu M, Selectivity Index for AChE > 22.857). 4,6-Diphenyl derivative 11g showed the highest and the most selectivity for BChE (IC50= 4.97 mu M, SI for AChE < 0.124). Interestingly, 4,5-diphenyl derivative 4g presented dual cholinesterase inhibition (AChE IC50= 5.11 mu M; BChE IC50= 14.16 mu M, SI for AChE = 2.771). Conclusion: Based on biological activity results and low toxicity of the compounds, it can be said that diphenyl substituted pyridazinone core is a valuable scaffold. Especially, dual inhibitory potencies of 4,5-diphenylpyridazin-3(2H)-one core for the cholinesterase enzymes and A beta-aggregation makes this core a promising disease-modifying agent.

Recently, chiral Bronsted bases having high basicity have emerged as a powerful tool in developing new catalytic enantioselective reactions. However, such chiral strong Bronsted base catalysts are still very scarce. Herein, we report the development of a chiral anionic Brensted base having a N,N’-dialkyl ureate moiety as a basic site. Its prominent catalytic activity was demonstrated in the enantioselective addition reactions of alpha-thioacetamides as less acidic pronucleophiles with various electrophiles. Thus, the newly developed chiral catalyst with high accessibility and structural tunability would expand the scope of viable enantioselective transformations under Bronsted base catalysis.
