Four novel Schiff bases 4-(2,4-dinitrobenzylideneamino)-5-m-tolyl-2H-1,2,4-triazole-3(4H)-thione) (F-1), 4-(2,4-dinitrobenzylideneamino)-5-(2-methoxyphenyl)-2H-1,2,4-triazole-3(4H)-thione) (F-2), 4-(2,4-dinitrobenzylideneamino)-5-(3-methoxyphenyl)-2H-1,2,4-triazole-3(4H)-thione) (F-3) and 4-(2,4-dinitrobenzylideneamino)-5-(4-methoxyphenyl)-2H-1,2,4-triazole-3(4H)-thione) (F-4) were prepared as new antifungal compounds contributing 4-Amino-5-Substituent-1,2,4-Triazole-3-Thione and 2,4-dinitrobenzaldehyde via a condensation reaction under the mild conditions with excellent yields. The structures of compounds were characterized by elemental analysis (EA), FT-IR, H-1 NMR, C-13 NMR spectra and X-ray analysis. In addition, the compounds were screened for in vitro biological activity, and the bioassay results indicated that the newly synthesized compounds showed different in vitro antifungal activities against five plant fungi. Particularly, compound F-3 (EC50 = 11.16 mg/L) was found to be the most active respectively against Wheat gibberellic, even more effective than Fluconazole (EC50 = 16.03 mg/L). The active compounds were further evaluated for enzyme inhibition efficacy against the receptor CYP51 by docking. Meanwhile, an explicit surface analysis on compounds were carried out theoretically using the wave function analyzer (Multiwfn 3.4.1 software) in order to study the reactivity of the compounds.

We synthesized N-benzoyl-protected peptide nucleic acid (PNA) monomers, which are robust under the conditions for deprotecting the 9-fluorenylmethoxycarbonyl (Fmoc) group by piperidine but are removable by aqueous ammonia and hence totally compatible with Fmoc-solid phase synthesis. This new invention expands the range of available nucleobase sequences, allowing us to use acid-sensitive PNA oligomers and purine nucleotides (both of which are difficult to use in the conventional methods) in the preparation of PNA-DNA chimeras to avoid the drawbacks of traditional PNAs.

P.; Procter, David J.] Univ Manchester, Dept Chem, Oxford Rd, Manchester M13 9PL, Lancs, England published Sulfoxide-mediated oxidative cross-coupling of phenols in 2020, Cited 67. The Name is 1,3-Dimethoxybenzene. Through research, I have a further understanding and discovery of 151-10-0.

A metal-free, oxidative coupling of phenols with various nucleophiles, including arenes, 1,3-diketones and other phenols, is reported. Cross-coupling is mediated by a sulfoxide which inverts the reactivity of the phenol partner. Crucially, the process shows high selectivity for cross-versus homo-coupling and allows efficient access to a variety of aromatic scaffolds including biaryls, benzofurans and, through an iterative procedure, aromatic oligomers.

Photochemistry provides a sustainable pathway for organic transformations by inducing radical intermediates from substrates through electron transfer process. However, progress is limited by heterogeneous photocatalysts that are required to be efficient, stable, and inexpensive for long-term operation with easy recyclability and product separation. Here, we report that boron carbonitride (BCN) ceramics are such a system and can reduce organic halides, including (het)aryl and alkyl halides, with visible light irradiation. Cross-coupling of halides to afford new C-H, C-C, and C-S bonds can proceed at ambient reaction conditions. Hydrogen, (het)aryl, and sulfonyl groups were introduced into the arenes and heteroarenes at the designed positions by means of mesolytic C-X (carbon-halogen) bond cleavage in the absence of any metal-based catalysts or ligands. BCN can be used not only for half reactions, like reduction reactions with a sacrificial agent, but also redox reactions through oxidative and reductive interfacial electron transfer. The BCN photocatalyst shows tolerance to different substituents and conserved activity after five recycles. The apparent metal-free system opens new opportunities for a wide range of organic catalysts using light energy and sustainable materials, which are metal-free, inexpensive and stable.

Formula: C8H8O2. I found the field of Chemistry; Science & Technology – Other Topics very interesting. Saw the article Table salt as a catalyst for the oxidation of aromatic alcohols and amines to acids and imines in aqueous medium: effectively carrying out oxidation reactions in sea water published in 2019, Reprint Addresses Elias, AJ (corresponding author), Indian Inst Technol, Dept Chem, New Delhi 110016, India.. The CAS is 99-04-7. Through research, I have a further understanding and discovery of 3-Methylbenzoic acid.

A simple, efficient, sustainable and economical method for the oxidation of alcohols and amines has been developed based on chloride, a sea abundant anionic catalyst for the practical synthesis of a wide range of carboxylic acids, ketones and imines. Oxidation of aromatic alcohols was carried out using NaCl (20 mol%) as the catalyst, NaOH (50 mol%) and aq. TBHP (4 equiv.) as the oxidant in 55-92% isolated yields. Oxidation of aromatic amines to imines was achieved by using only 20 mol% of NaCl and aq. TBHP (4 equiv.) in 32-93% isolated yields. The chlorine species formed during the reaction as the active oxidation catalyst has been identified as ClO2- for alcohols and ClO-/ClO2- for amines by control experiments. This method is mostly free from chromatographic purification, which makes it suitable for large-scale synthesis. We have scaled up to 30 gram scale the synthesis of carboxylic acids and imines in good yields and have also carried out efficiently this new method using filtered sea water as the solvent and catalyst.

To develop antitumor drugs capable of targeting energy metabolism in the tumor microenvironment, we produced a series of potent new biguanide derivatives via structural modification of the arylbiguanide scaffold. We then conducted biological screening using hypoxia inducible factor (HIF)-1- and unfolded protein response (UPR)-dependent reporter assays and selective cytotoxicity assay under low glucose conditions. Homologation studies of aryl-(CH2)(n)-biguanides (n=0-6) yielded highly potent derivatives with an appropriate alkylene linker length (n=5, 6). The o-chlorophenyl derivative 7l (n=5) indicated the most potent inhibitory effects on HIF-1- and UPR-mediated transcriptional activation (IC50; 1.0 +/- 0.1 mu M, 7.5 +/- 0.1 mu M, respectively) and exhibited selective cytotoxicity toward HT29 cells under low glucose condition (IC50; 1.9 +/- 0.1 mu M). Additionally, the protein expression of HIF-1 alpha induced by hypoxia and of GRP78 and GRP94 induced by glucose starvation was markedly suppressed by the biguanides, thereby inhibiting angiogenesis. Metabolic flux and fluorescence-activated cell sorting analyses of tumor cells revealed that the biguanides strongly inhibited oxidative phosphorylation and activated compensative glycolysis in the presence of glucose, whereas both were strongly suppressed in the absence of glucose, resulting in cellular energy depletion and apoptosis. These findings suggest that the pleiotropic effects of these biguanides may contribute to more selective and effective killing of cancer cells due to the suppression of various stress adaptation systems in the tumor microenvironment.

Intramolecular amination of organoboronates occurs with a 1,2-metalate shift of an aminoboron ate complex to form azetidines, pyrrolidines, and piperidines. Bis(boronates) undergo site-selective amination to form boronate-containing azacycles. Enantiomerically enriched azacycles are formed with high stereospecificity.
