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.

The nitrogen and phosphorus co-doped graphene-like carbon (NPG) is cost-effective fabricated by simple ball-milling and thermal treatment. The as-prepared NPG can be used as a metal-free catalyst for selective catalytic oxidation of aromatic alcohols to their corresponding acids by using TBHP and O-2 as the oxidant in water. It is observed that various aromatic alcohols bearing electron-donating/withdrawing groups can be oxidized to the corresponding acids in excellent yields. No dehalogenation and steric-hindrance effects are detected in this oxidation process. In addition, the NPG catalyst can be easily separated and efficiently reused seven times, showing good recyclability.

The hypoxia-inducible factor-la (HIF-1 alpha) pathway has been implicated in tumor angiogenesis, growth, and metastasis. Therefore, the inhibition of this pathway is an important therapeutic target for the treatment of various types of cancers. Here, we designed and synthesized 31 ursolic acid (UA) derivatives containing a tetrazole moiety and evaluated them for their potential anti-tumor activities as HIF-la transcriptional inhibitors. Of these, compound 14d (IC50 0.8 +/- 0.2 mu M) displayed the most potent activity and compounds 14a (IC50 4.7 +/- 0.2 mu M) exhibited the most promising biological profile. Analysis of the structure-activity relationships of these compounds with HIF-1 alpha suggested that the presence of a tetrazole group located at C-28 of the UA derivatives was critical for their inhibitory activities.

Diflubenzuron (DFB) and fenuron (FEN) are benzoylurea and phenylurea pesticides, widely used in Senegal, that do not exhibit any natural fluorescence, but can be determined by means of photoinduced fluorescence (PIF) methods. Photodegradation of DFB and FEN yielded a number of fluorescent and non-fluorescent photoproducts. For both pesticides, at least 10 photoproducts were detected and identified by gas chromatography-mass spectrometry (GC/MS). To identify the formed fluorescent DFB and FEN photoproducts, their fluorescence spectra were compared with those of standard compounds, including phenol and p-hydroxyaniline.

An approach for the calculation of the vaporization enthalpies of aromatic and heteroaromatic compounds at T = 298.15 K with accuracy competitive with experiment was proposed. The vaporization enthalpies may be calculated from the solution enthalpies of liquid and solvation enthalpies in benzene. The solution enthalpies of liquids were shown to be constant within a given type of aromatic compounds. For a set of 67 liquid and 41 solid aromatic and heteroaromatic compounds not capable of intermolecular hydrogen bonding, it was experimentally demonstrated that the solution enthalpies of liquids or supercooled liquids in benzene were equal to 1 +/- 1 kJ . mol(-1). The way to consider intermolecular hydrogen bonding, e.g., in phenol, aniline, pyrrole derivatives, was also proposed. The methods for solvation enthalpy calculation were proposed previously. The calculated and literature vaporization enthalpies values of 415 aromatic and heteroaromatic compounds were compared. Average absolute deviation amounted to 1.3 kJ . mol(-1). The proposed approach is especially valuable for calculation of the vaporization enthalpies of low-volatile compounds, including those solid at T = 298.15 K. (C) 2020 Elsevier B.V.

A novel, quick, environmentally safe, and one-pot synthesis of a series of N,N-bis(cyanoacetyl)hydrazine derivatives, bis-imino-2H-chromenes and bis-2-oxo-2H-chromene derivatives have been designed. Some selected newly synthesized compounds were investigated in vitro for their antibacterial activity. Compound 5j is the most toxic compound against Staphylococcus aureus with activity index 171%, followed by compound 15b with activity index 136% compared to standard drug ampicillin. Moreover, compound 15a is the most toxic compound against Escherichia coli with activity index 111% compared to standard drug gentamicin. Minimum inhibitory concentration (MIC) was carried out for compounds with high antibacterial activity. Compound 5j has good MIC (7.8 mu g/ml) against Staphylococcus aureus while 15a has good MIC (31.25 mu g/ml) against Streptococcus mutans which is better than MIC of the standard drug ampicillin (MIC = 62.5 mu g/ml). Compounds 5j, 5k, 15a, 15b and 15e which have good MIC values were introduced to enzyme assay against DNA gyrase and topoisomerase IV. The results showed that compound 15a can strongly inhibit DNA gyrase and topoisomerase IV (IC50 = 27.30 and 25.52 mu M respectively), compared to methotrexate as the standard drug (IC50 = 29.01 and 23.55 mu M respectively). Structure-activity relationships were also discussed based on the biological and docking simulation results.

In the presented work, we report the synthesis of a series of 4-benzylidene-2-phenyl-5(4H)-imidazolone-based benzenesulfonamides 7a-f via the Erlenmeyer-Plochl reaction. All the prepared imidazolones 7a-f were evaluated as inhibitors of human (h) carbonic anhydrases (CA, EC 4.2.1.1) cytosolic isoforms hCA I and II, as well as transmembrane tumor-associated isoforms hCA IX and XII. All the tested hCA isoforms were inhibited by the prepared imidazolones 7a-f in variable degrees with the following KIs ranges: 673.2-8169 nM for hCA I, 61.2-592.1 nM for hCA II, 23-155.4 nM for hCA XI, and 21.8-179.6 nM for hCA XII. In particular, imidazolones 7a, 7e, and 7f exhibited good selectivity towards the tumor-associated isoforms (CAs IX and XII) over the off-target cytosolic (CAs I and II) with selectivity index (SI) in the range of 6.2-19.4 and 3.3-8, respectively. Moreover, imidazolones 7a-f were screened for their anticancer activity in one dose (10(-5) M) assay against a panel of 60 cancer cell lines according to US-NCI protocol. Furthermore, 7a, 7e and 7f were evaluated for their anti-proliferative activity against colorectal cancer HCT-116 and breast cancer MCF-7 cell lines. Furthermore, 7e and 7f were screened for cell cycle disturbance and apoptosis induction in HCT-116 cells. Finally, a molecular docking study was carried out to rationalize the obtained results.

Direct synthesis of N-(hetero)arylated heteroarenes has been realized through Cu-mediated C-N coupling of NH azaheterocycles with aryl C-H bonds under aerobic conditions. This method features a broad scope of both heterocyclic arenes (pyridine, quinoline, pyrazole, imidazole, furan, thiophene, benzofuran, and indole) and NH azaheterocycles (imidazole, pyrazole, indole, azindole, purine, indazole, benzimidazole, pyridone, carbazole), providing a versatile method for the synthesis of pharmaceutically important N-(hetero)arylated heteroarenes. The versatility of this reaction was further demonstrated through late-stage modification of marketed drugs and the synthesis of a key intermediate for accessing a class of angiotensin II receptor 1 antagonists.

A new metal-, oxidant-, and solvent-free ecofriendly domino method has been established for modular synthesis of a diverse range of medicinally promising hydroxyarylated unsymmetrical pyridines in good to high chemical yields with an excellent regioselectivity. This domino process involves a range of N-sulfonyl ketimines as C,N-binucleophiles, enolizable ketones, and aromatic/heteroaromatic aldehydes using ammonium acetate as an ideal promoter under neat conditions, which creates two new C-C bonds and one C-N bond. Notably, the neutral reaction conditions are mild enough to tolerate a range of functionalities and cover a variety of substrates, thus bestowing a powerful avenue to access tri- and tetrasubstituted pyridines including carbo- and heterocyclic fused ones. Interestingly, a practical, scalable, and high-yielding synthesis of pyridylphenol derivatives was successfully accomplished by our unique method.
