An iron-catalysed allylation of organomagnesium reagents (alkyl, aryl) with simple allyl acetates proceeds under mild conditions (Fe(OAc)(2) or Fe(acac)(2), Et2O, r.t.) to furnish various alkene and styrene derivatives. Mechanistic studies indicate the operation of a homotopic catalyst. The sequential combination of such iron-catalysed allylation with an iron-catalysed hydrogenation results in overall C(sp(3))-C(sp(3))-bond formation that constitutes an attractive alternative to challenging direct cross-coupling protocols with alkyl halides.

Cyanobacteria is blue-green microalgae that produces a variety of secondary metabolites such as antibiotic, cytotoxic and antimicrobial agents. Present investigation proposed to study an extraction of active agents from Cyanobacteria and its antibacterial activity. The Cyanobacteria were collected, and isolated colony was found to be Oscillatoria sp. and it was grown in BG 11 medium for mass cultivation. Then the centrifuged biomass was weighed and used for extraction of bioactive compounds. GCMS analysis from Oscillatoria sp. determines fatty acid, triazine derivatives, pyridine derivatives, acridine derivatives. The result revealed that Oscillatoria sp. can play crucial roles as antibacterial agents because the methanolic extract are inhibiting the growth of S. aureus for gram-positive whereas P. aeruginosa for gram-negative bacteria. The crude extract was effective against S. aureus with the highest concentration, 100 mg/ml where area of the zone was 14.10 +/- 0.8 mm. The crude extract actively inhibited P. aeruginosa at 75 and 100 mg/ml with highest area of inhibition were in the average of 13.23 +/- 0.1 and 15.43 +/- 0.2 mm. Finally, the antimicrobial activity was carried out by disc diffusion method with different concentrations of active compounds shows the MIC value in gram-positive bacteria was 30 mu g/ml whereas for gram-negative bacteria was 25 mu g/nnl. Cyanobacteria extract should be preferred and considered to be new natural drug or antibiotics in pharmaceutical and health care industry. This coastal region should be studied further by researchers to study more information and benefits in the future.

A palladium-dihydroxyterphenylphosphine (DHTP) catalyst was successfully applied to the direct C3-arylation of N-unsubstituted indoles with aryl chlorides, triflates, and nonaflates. This catalyst showed C3-selectivity, whereas catalysts with other structurally related ligands exhibited N1-selectivity. Complex formation between the lithium salts of the ligand and the indole is assumed to accelerate the arylation at the C3 position. Reactions using 3-alkylindoles afforded 3,3-disubstituted indolenines, which can be further converted to the corresponding indoline derivatives.

The design and application of environmentally friendly catalysts to reduce the quantity of toxic wastes is critical for improving the chemical synthesis process. Therefore, BaFe12O19/Al2O3, a magnetic mesoporous nanocomposites, were designed synthesized and characterized using different techniques such as energy dispersive X-ray (EDX) spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM), Brunauer-Emmett-Teller (BET) adsorption method, and vibrating sample magnetometry (VSM). The prepared BaFe12O19/Al2O3 display a high surface area (1773.22 m(2)/g) with an average pore diameter of 3.946 nm from nitrogen sorption analysis. In addition, the synthesized nanocomposites prove to be an active heterogeneous Lewis acid catalyst for the solvent free synthesis of alpha-aminophosphonates at ambient temperature, through three-component reaction of aldehydes/ketones, amines and triethyl phosphite. The use of this catalyst results in an effortless magnetic recoverability and recyclability, high yield and short reaction time under solvent-free conditions. Graphic

Twenty derivatives of chalcones were synthesized and their anticancer activities were estimated against both breast and liver cancer besides two human normal cell lines. Out of our candidates, there were five compounds 3 b, 3 d, 3 h, 7 and 10 b that revealed a broad superlative antitumor activity against both HepG2 and MCF7 cell lines. Surprisingly, 3 h showed the most powerful anticancer activity (GI(50)=5.43 +/- 0.170 mu M for MCF7 and GI(50)=1.80 +/- 0.50 mu M for HepG2) and displayed the most effective inhibition activity on tubulin with IC50=4.51 +/- 0.13 mu M. 3 h exerted low toxicity toward both normal human, Hs371.T and AML12, cell lines. 3 h revealed arrest of cell cycle at G2/M and induced apoptosis compared to control cells. Docking study of all newly derivatives was achieved to decide the preeminent binding mode. Generally, the outcome of the docking study showed that 3 h had better binding mode.

The Name is Benzyl Alcohol. Through research, I have a further understanding and discovery of 100-51-6.

A Ru-II-NH3 complex, 2, was oxidized through a proton-coupled electron transfer (PCET) mechanism with a Ce-IV complex in water at pH 2.5 to generate a Ru-v=NH complex, 5. Complex 5 was characterized with various spectroscopies, and the spin state was determined by the Evans method to be S = 1/2. The reactivity of 5 in substrate C-H oxidation was scrutinized in acidic water, using water-soluble organic substrates such as sodium ethylbenzene-sulfonate (EBS), which gave the corresponding 1-phenylethanol derivative as the product. In the substrate oxidation, complex 5 was converted to the corresponding Ru-III-NH3 complex, 3. The formation of 1-phenylethanol derivative from EBS and that of 3 indicate that complex 5 as the oxidant does not perform nitrogen-atom transfer, in sharp contrast to other high-valent metal-imido complexes reported so far. Oxidation of cyclobutanol by 5 afforded only cyclobutanone as the product, indicating that the substrate oxidation by 5 proceeds through a hydride-transfer mechanism. In the kinetic analysis on the C-H oxidation, we observed kinetic isotope effects (KIEs) on the C-H oxidation with use of deuterated substrates and remarkably large solvent KIE (sKIE) in D2O. These positive KIEs indicate that the rate-determining step involves not only cleavage of the C-H bond of the substrate but also proton transfer from water molecules to 5. The unique hydride-transfer mechanism in the substrate oxidation by 5 is probably derived from the fact that the Ru-IV-NH2 complex (4) formed from 5 by 1e(-)/1H(+) reduction is unstable and quickly disproportionates into 3 and 5.

o-Alkenylation of unprotected phenols has been developed by direct C-H functionalization catalyzed by PdII. This work features phenol group as a directing group and realizes highly site-selective C-H bond functionalization of phenols to achieve the corresponding products in moderate to excellent yields at 60 degrees C. The advantages of this reaction include unprecedented C-H functionalization using phenol as a directing group, high regioselectivity, good substrate scope, mild reaction conditions, and high efficiency. To the best of our knowledge, this is the first example of a regioselective C-H alkenylation of unprotected phenols utilizing phenolic hydroxyl group as a directing group. The alkenylation of unprotected tyrosine and intramolecular cyclization are also successfully carried out under this catalytic system in good yields. Furthermore, this novel method enables a late-stage modification of complex phenol-containing bioactive molecules toward a diversity-oriented drug discovery.

Two new series of diethyl 2-[2-(substituted-2-oxo-1,2-dihydroquinolin-4-yl)hydrazono]-succinates 6a-g and 1-(2-oxo-1,2-dihydroquinolin-4-yl)-1H-pyrazoles 7a-f have been designed and synthesized. The structures of the synthesized compounds were proved by IR, mass, NMR (2D) spectra and elemental analyses. The target compounds were evaluated for their in vitro cytotoxic activity against 60 cancer cell lines according to NCI protocol. Consequently, seven compounds were further examined against the most sensitive cell lines, leukemia CCRFCEM, and MOLT-4. 5-Amino-1-(6-bromo-2-oxo-1,2-dihydroquinolin-4-yl)-1H-pyrazole-3,4-dicarbonitrile (7f) was the most active product, with IC50= 1.35 uM and 2.42 uM against MOLT-4 and CCRF-CEM, respectively. Also, it showed a remarkable inhibitory activity compared to erlotinib on the EGFR TK with IC50 = 247.14 nM and 208.42 nM, respectively. Cell cycle analysis of MOLT-4 cells treated with 7f showed cell cycle arrest at G2/M phase (supported by Caspases, BAX and Bcl-2 studies) with a significant pro-apoptotic activity as indicated by annexin V-FITC staining. Moreover, the docking study indicated that both the pyrazole moiety and the quinolin-2-one ring showed good fitting into EGFR (PDB code: 1M17). In order to interpret SAR of the designed compounds, and provide a basis for further optimization, molecular docking of the synthesized compounds to known EGFR inhibitors was performed. The study illustrated the effect of several factors on the compounds’ activity.
