Background/Aims: Hydrazone and acylhydrazone derivatives, which are produced from aldehyde reacting with hydrazine or acylhydrazine, have been reported to exhibit antitumor activities. However, the angionenic effects of this kind of derivatives haven’t been elucidated. Here, we synthesized 12 pyridoxal hydrazone and acylhydrazone compounds and investigated their antiangiogenic effects and the underlying mechanisms. Method: 3-(4,5-Dimethylthiazol-2-yl)-2, 5-dipheyltetrazolium bromide assay was used to screen the inhibitory effects of the synthesized compounds on endothelial cells (ECs) proliferation. The compound with best inhibitory effect was further evaluated with wound-healing assay and tube formation assay. Calcein-Am assay was carried out to determine the content of intracellular labile iron pool (LIP). Intracellular reduced glutathione (GSH) was determined by spectrophotometry. Flow cytometry was used to determine cell cycle and apoptosis. Results: Compound 10 (3-hydroxy-5-[hydroxymethyl]-2-methyl-pyridine-4-carbaldehyde-2-naphthalen-1-acetyl hydrazone) showed the best inhibitory effect on human umbilical vascular ECs proliferation, with IC50 value of 25.4 mu mol/L. It not only inhibited wound-healing and tube formation of ECs, but also decreased the content of intracellular LIP and GSH. Furthermore, it arrested ECs cycle at S phase and induced cell apoptosis. Conclusions: Compound 10 exhibits antiangiogenic effects by reducing the content of intracellular LIP and GSH, and subsequently arresting cell cycle and inducing cell apoptosis.

We report a mild palladium-catalyzed selective dehydrogenation of 4-alkylpyridines that exploits their soft enolization to alkylidene dihydropyridines using allyl chloroformate under metal-free conditions. Treatment of these intermediates with a palladium catalyst liberates an alkylpyridylic anion and an allylpalladium(II) intermediate, which combine and undergo beta-hydride elimination to install a double bond. Importantly, the formation of gas byproducts makes the process very practical. Furthermore, the reaction tolerates a broad range of functional groups, including many that can be dehydrogenated using similar palladium-catalyzed reactions, and is selective for 4-alkylpyridines even in substrates bearing multiple pyridylic positions.

The discovery of potent kinase inhibitors with tunable selectivity and specificity has gained significant impetus in the last few decades. In accordance with this development, herein, we report the design and synthesis of a series of new heterocyclic derivatives comprising a 1,2,4 triazole nucleus, tethered to two flexible linkers on either side, utilizing a simple Schiff base approach (compounds 1-16). The compounds were characterised by various spectroscopic techniques and their biological evaluation was conducted using kinase inhibition assay on two targets, namely CLK1 and DYRK1A. Our investigation reveals that compounds 3-5 bearing hydroxy/methoxy substituents in the aromatic ring display excellent potency towards the receptors in the micromolar range. Indeed, compound 5 bearing a methoxy substitution at the meta position possesses the added advantage of being highly specific towards CLK1 among the targets. To reinforce this observation, we performed molecular modelling studies with the kinase inhibitors hymenialdisine (HMD) cocrystallized with CLK1 and harmine (HA) cocrystallized with DYRK1A kinases as references. We speculate that in either target, the cause of such high potency and selectivity might be attributed to the involvement of flexible linkers on either side of the triazole core, which might have compelled the ligands to enter into the active site of the receptor and maximize non-covalent interactions. Interestingly, we consider the selectivity of compound 5 to be due to the involvement of a H-bond between SH of triazole and Glu 169 carbonyl in the receptor, which is absent in the other derivatives for both targets. Thus, our efforts focus on how the variation/position of substituents in the inhibitors has a profound impact on potency and selectivity. Indeed, this work establishes innovative design principles towards the development of a therapeutic agent for the treatment of neurodegenerative diseases like that of Alzheimers.

Curcumin and trans-cinnamaldehyde are acrolein-based Michael acceptor compounds that are commonly found in domestic condiments, and known to cause cancer cell death via redox mechanisms. Based on the structural features of these compounds we designed and synthesized several 2-cinnamamido-N-substituted-cinnamamide (bis-cinnamamide) compounds. One of the derivatives, (Z)-2-[(E)-cinnamamido]-3-phenyl-N-propylacrylamide 8 showed a moderate antiproliferative potency (HCT-116 cell line inhibition of 32.0 mu M), no inhibition of normal cell lines C-166, and proven cellular activities leading to apoptosis. SAR studies led to more than 10-fold increase in activity. Our most promising compound, [(Z)-3-(1H-indol-3-yl)-N-propyl-2-[(E)-3-(thien-2-yl)propenamido) propenamide] 45 killed colon cancer cells at IC50 = 0.89 mu M (Caco-2), 2.85 mu M (HCT-116) and 1.65 mu M (HT -29), while exhibiting much weaker potency on C-166 and BHK normal cell lines (IC50 = 71 mu M and 77.6 mu M, respectively). Cellular studies towards identifying the compounds mechanism of cytotoxic activities revealed that apoptotic induction occurs in part as a result of oxidative stress. Importantly, the compounds showed inhibition of cancer stem cells that are critical for maintaining the potential for self-renewal and stemness. The results presented here show discovery of covalently acting Michael addition compounds that potently kill cancer cells by a defined mechanism, with prominent selectivity profile over non-cancerous cell lines.

Although pyridine derivatives are versatile supporting ligands in catalysis, the development of their chiral versions has been relatively limited. Herein, we report the design, synthesis, and proof-of-concept application of a structurally tunable chiral pyridine framework featuring an annulated compact ring system. Using an N,B-bidentate ligand skeleton containing the chiral pyridine moiety, we have developed an enantioselective iridium-catalyzed desymmetrizing C-H borylation reaction of diaryl(2-pyridyl)methane compounds with up to 96% ee and 93% yield. The resulting borylation products could be readily transformed into various chiral tri(hetero)arylmethane compounds. Density functional theory investigations revealed that the two chair conformations of the flexible ketal motif both favored the enantiomer that was consistent with experimental results. This work has thus introduced an effective and tunable chiral pyridine ligand framework that may be used in many catalytic asymmetric transformations.

Being a handle for synthesizing quaternary carbon centers and olefins, together with ubiquitous appearance in organic building blocks, makes tertiary alcohols valuable targets in synthesis. However, traditional syntheses of these alcohols have faced several challenges including the employment of functionalized reactive reagents, undesirable side reactions, and decomposition of the alcohol products under harsh conditions. The paucity of a synthetic approach to bulky tertiary alcohols prompts our interest to develop a benign catalytic protocol to tackle the current issues. Here, we have successfully demonstrated the use of ketyl radicals in intermolecular cross radical-radical coupling, which has opened a different door for accessing complex tertiary alcohols. On the other hand, by starting from feedstock and naturally derived chemicals without any pre-activation, it would be superior to traditional methodologies in the industrial context.

The photoswitching properties of three readily accesible benzoylpyridine hydrazones were investigated. Interestingly, replacing classical stirring with ultrasound wave activation results in pure thermodynamically less stable E isomer crystallization at room temperature. The studied benzoylpyridine hydrazones exhibit both P- and T-photochromic behaviour, depending on the benzoyl substituent, and improved addressability compared to most of the previously published pyridyl based hydrazones and 2-pyridylcarboxaldehyde acylhydrazones. Low activation entropy and calculated transition state geometry favour the inversion mechanism of their thermal isomerization rather than tautomerization followed by rotation recently found for pyridyl-hydrazone ester or nitrile rotary switches. The association behaviour of the nitro derivative during its thermal E-to-Z isomerization in highly polar DMSO indicates an important role of intermolecular hydrogen bonding in the thermal kinetics of benzoylpyridine-based hydrazone photoswitches. Moreover, the addition of triethylamine significantly accelerates the rate of Z-isomer thermal isomerization from days to seconds and could thus pave the way to fast pyridyl hydrazone T-type photochromic compounds in polar solvents. This study could therefore contribute to general knowledge related to the photochromic behaviour of hydrazones as an important class of modern photoswitches.

We herein report the fabrication of a bifunctional iron nanocomposite catalyst, in which two catalytically active sites of Fe-N-x and Fe phosphate, as oxidation and Lewis acid sites, were simultaneously integrated into a hierarchical N,P-dual doped porous carbon. As a bifunctional catalyst, it exhibited high efficiency for direct oxidative cleavage of alkenes into ketones or their oxidation into 1,2-diketones with a broad substrate scope and high functional group tolerance using TBHP as the oxidant in water under mild reaction conditions. Furthermore, it could be easily recovered for successive recycling without appreciable loss of activity. Mechanistic studies disclose that the direct oxidation of alkenes proceeds via the formation of an epoxide as intermediate followed by either acid-catalyzed Meinwald rearrangement to give ketones with one carbon shorter or nucleophilic ring-opening to generate 1,2-diketones in a cascade manner. This study not only opens up a fancy pathway in the rational design of Fe-N-C catalysts but also offers a simple and efficient method for accessing industrially important ketones and 1,2-diketones from alkenes in a cost-effective and environmentally benign fashion.

Application In Synthesis of 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride. I found the field of Biochemistry & Molecular Biology very interesting. Saw the article Exploratory metabolomic study to identify blood-based biomarkers as a potential screen for colorectal cancer published in 2019.0, Reprint Addresses Louie, SG (corresponding author), Univ Southern Calif, Sch Pharm, Dept Clin Pharm, Los Angeles, CA 90089 USA..

Introduction: colorectal cancer (CRC) continues to be difficult to diagnose due to the lack of reliable and predictive biomarkers. Objective: to identify blood-based biomarkers that can be used to distinguish CRC cases from controls. Methods: a workflow for untargeted followed by targeted metabolic profiling was conducted on the plasma samples of 26 CRC cases and ten healthy volunteers (controls) using liquid chromatography-mass spectrometry (LCMS). The data acquired in the untargeted scan was processed and analyzed using MarkerViewt software. The significantly different ions that distinguish CRC cases from the controls were identified using a mass-based human metabolome search. The result was further used to inform the targeted scan workflow. Results: the untargeted scan yielded putative biomarkers some of which were related to the folate-dependent one-carbon metabolism (FOCM). Analysis of the targeted scan found the plasma levels of nine FOCM metabolites to be significantly different between cases and controls. The classification models of the cases and controls, in both the targeted and untargeted approaches, each yielded a 97.2% success rate after cross-validation. Conclusion: we have identified plasma metabolites with screening potential to discriminate between CRC cases and controls.
