BACKGROUND Deep eutectic solvents (DESs) are prepared by mixing solid organic precursors to form a liquid driven from strong hydrogen-bond interactions. The physical and chemical properties of these compounds have been widely investigated, and it has been shown that they are benign media for biotransformations, organicsynthesis, biodieselpreparation, and a sustainable media for nanoscale and functional materials. RESULTS This study is the first report on the synthesis of n-TiO2-P25@TDI@DES (urea: ZnCl2) with photo catalytic activity. This nano photocatalyst was obtained through covalent grafting of TiO2-P25 nanoparticles to an inexpensive and highly reactive linker (2,4-toluene diisocyanate). The presented nano photocatalyst has been employed as a covalently grafted Lewis acidic deep eutectic solvent to oxidize various primary benzyl alcohols to their corresponding carbonyl compounds by sodium nitrate as oxidant, under visible light exposure. CONCLUSION This highly efficient nanocatalyst was investigated by various characterization techniques including fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy equipped with energy-dispersive X-ray spectroscopy (SEM with EDX), and elemental analysis. Owing to its enhanced catalytic activity, thermal stability, and environmentally friendly nature, the present method can be regarded as an attractive green chemistry approach.

Isocombretastatins are the not isomerizable 1,1- diarylethene isomers of combretastatins. Both families of antimitotics are poorly soluble and new analogs with improved water solubility are needed. The ubiquitous 3,4,5-trimethoxyphenyl ring and most of its replacements contribute to the solubility problem. 39 new compounds belonging to two series of isocombretastatin analogs with 2-chloro-6-methylsulfanyl-4-pyridinyl or 2,6-bis(methylsulfanyl)-4-pyridinyl moieties replacing the 3,4,5-trimethoxyphenyl have been synthesized and their antimitotic activity and aqueous solubility have been studied. We show here that 2-chloro-6-methylsulfanylpyridines are more successful replacements than 2,6-bis(methylsulfanyl) pyridines, giving highly potent tubulin inhibitors and cytotoxic compounds with improved water solubilities. The optimal combination is with indole rings carrying polar substitutions at the three position. The resulting diheteroaryl isocombretastatin analogs showed potent cytotoxic activity against human cancer cell lines caused by tubulin inhibition, as shown by in vitro tubulin polymerization inhibitory assays, cell cycle analysis, and confocal microscopy studies. Cell cycle analysis also showed apoptotic responses following G(2)/M arrest after treatment. Conformational analysis and docking studies were applied to propose binding modes of the compounds at the colchicine site of tubulin and were in good agreement with the observed SAR. 2-Chloro-6-methylsulfanylpyridines represent a new and successful trimethoxyphenyl ring substitution for the development of improved colchicine site ligands.

For the first time, chemical modification of raw Luffa with hydrogen sulfate moieties was investigated. For this purpose ammonium hydrogen sulfate moieties were immobilized on the surface of Luffa. This chemical modification performed by reaction of 3-aminopropyltriethoxy silane with raw Luffa and sulfonation of amine groups using sulfuric acid. The morphology of catalyst was investigated by Fourier transform spectroscopy, X-ray diffraction, thermogravimetric analysis, field emission scanning electron microscope, elemental-mapping, and energy dispersive X-Ray spectroscopy techniques. The catalytic performance of the synthesized catalyst was examined in the synthesis of coumarin and bis(indolyl)methane derivatives. Our method introduced a green protocol in using of a plant for the preparation of catalyst and one-pot solventless media for the synthesis of coumarins and bis(indolyl)methanes. Some of the advantages of our method are high yields of products, short reaction times, recyclability of catalyst, easy workup, and separation of catalyst and products.

Guillermo Calleja and co-workers from @urjc describe URJC-1-MOF as a new heterogeneous recyclable catalyst for c-heteroatom coupling reactions The capacity of copper-based URJC-1-MOF as a MOF catalyst in cross-coupling reactions has been evaluated, focusing on the Chan-Lam-Evans arylation-type reactions on amines and alcohols without extra additives or ligands. The extraordinary chemical and structural stability of URJC-1-MOF and its good specific surface, make this material a promising alternative to homogeneous Cu (II) catalysts for cross-coupling reactions. URJC-1-MOF showed a remarkable catalytic activity for cross-coupling C-N and C-O reactions, higher than other heterogeneous and homogeneous copper-based catalyst, such as CuO, HKUST-1, Cu-MOF-74, Cu(OAc)(2) and CuSO4.5H(2)O. Moreover, its easy recovery by simple filtration and reusability in successive runs without any loss of activity and stability, demonstrates the potential of URJC-1-MOF as an alternative catalyst for this kind of reactions in different chemical media of industrial interest.

Methods to activate the relatively stable ether C-O bonds and convert them to other functional groups are desirable. One-electron reduction of ethers is a potentially promising route to cleave the C-O bond. However, owing to the highly negative redox potential of alkyl aryl ethers (E-red < -2.6 V vs SCE), this mode of ether C-O bond activation is challenging. Herein, we report the visible-light-induced photocatalytic cleavage of the alkyl aryl ether C-O bond using a carbazole-based organic photocatalyst (PC). Both benzylic and non-benzylic aryl ethers underwent C-O bond cleavage to form the corresponding phenol products. Addition of Cs2CO3 was beneficial, especially in reactions using a N-H carbazole PC. The reaction was proposed to occur via single-electron transfer (SET) from the excited-state carbazole to the substrate ether. Interaction of the N-H carbazole PC with Cs2CO3 via hydrogen bonding exists, which enables a deprotonation-assisted electron-transfer mechanism to operate. In addition, the Lewis acidic Cs cation interacts with the substrate alkyl aryl ether to activate it as an electron acceptor. The high reducing ability of the carbazole combined with the beneficial effects of Cs2CO3 made this otherwise formidable SET event possible. Category: indole-building-block.

meta-Aminophenols are formed by the action of DBU on 3-amino-2-chlorocyclohex-2-en-1-ones at room temperature in MeCN. The chloro compounds are generated by treating 3-aminocyclohex-2-en-1-ones with the easily prepared halogenating agent BnNMe3 center dot ICl2 in MeOH-CH2Cl2. The amino group must carry two substituents, either two aryl, one aryl and one alkyl, or two alkyl groups; 3-aminocyclohex-2-en-1-ones of this type are readily made from cyclohex-2-en-1-one and a primary or secondary amine.

The synthesized MgTi2O4.TiO2.Zn2TiO4 nanomaterial was characterized by XRD (X-Ray diffraction), SEM (Scanning electron microscopy), EDS (Energy dispersive x-ray spectroscopy), FTIR (Fourier transform infrared spectroscopy) and PL (Photoluminescence) study. Particles size of MgTi2O4.TiO2.Zn2TiO4 nanomaterial was found to be 37.3 nm. PL and PLE (Photoluminescence excitation) spectra are showed several peaks including one red PL at 723 nm, when excited at 320 nm. Nanomaterial was subject to electrochemical sensor study. Thin layer of synthesized MgTi2O4.TiO2.Zn2TiO4 nanomaterials was fabricated onto the glassy carbon electrode (GCE) with conducting binder to result the working electrode of 4-nitrophenylhydrazine (4-NPHyd) sensor, which was applied successively to selectively detect the 4-NPHyd in aqueous phase. The 4-NPHyd chemical sensor exhibited high sensitivity with lower detection limit, long-term stability in chemical environment and improved electrochemical responses during sensing performance. The linearity of calibration plot is obtained over the large linear dynamic range (LDR) from 0.1 nM to 0.1 mM of 4-NPHyd. The sensitivity calculated from the slop of calibration plot (ratio of current to concentration of 4-NPHyd) is 42.7215 mu AmM(-1)cm(-2) with detection limit (DL) of 0.02 +/- 0.001 nM at signal to noise ratio of 3(S/N). Therefore, the chemical sensor based on MgTi2O4.TiO2.Zn2TiO4 nanomaterials may be a promising highly sensitive sensor in electrochemical method for the effective detection of hazardous and carcinogenic chemicals in medical as well as biological sectors.

Recently, inhibition of carbonic anhydrase (hCA) and acetylcholinesterase (AChE) have appeared as a promising approach for pharmacological intervention in a variety of disorders such as glaucoma, epilepsy, obesity, cancer, and Alzheimer’s disease. Keeping this in mind, N, N’-bis[(1-aryl-3-heteroaryl) propylidene] hydrazine dihydrochlorides, N1-N11, P1, P4-P8, and R1-R6, were synthesized to investigate their inhibitory activity against hCA I, hCA II, and AChE enzymes. All compounds in N, P, and R-series inhibited hCAs (I and II) and AChE more efficiently than the reference compounds acetazolamide (AZA), and tacrine. According to the activity results, the most effective inhibitory compounds were in R-series with the K-i values of 203 +/- 55-473 +/- 67 nM and 200 +/- 34-419 +/- 94 nM on hCA I, and hCA II, respectively. N, N’-Bis[1-(4-fluorophenyl)-3-(morpholine-4-yl) propylidene] hydrazine dihydrochlorides, N8, in N-series, N, N’-Bis[1-(4-hydroxyphenyl)-3-(piperidine-1-yl) pro-pylidene] hydrazine dihydrochlorides, P4, in P-series, and N, N’-bis[1-(4-chlorophenyl)-3-(pyrrolidine-1-yl) pro-pylidene] hydrazine dihydrochlorides, R5, in R-series were the most powerful compounds against hCA I with the K-i values of 438 +/- 65 nM, 344 +/- 64 nM, and 203 +/- 55 nM, respectively. Similarly, N8, P4, and R5 efficiently inhibited hCA II isoenzyme with the K-i values of 405 +/- 60 nM, 327 +/- 80 nM, and 200 +/- 34 nM, respectively. On the other hand, P-series compounds had notable inhibitory effect against AChE than the reference compound tacrine and the K-i values were between 66 +/- 20 nM and 128 +/- 36 nM. N, N’-Bis[1-(4-fluorophenyl)-3-(piperidine-1-yl) propylidene] hydrazine dihydrochlorides, P7, was the most potent compound on AChE with the K-i value of 66 +/- 20 nM. The other most promising compounds, N, N’-bis[1-(4-hydroxyphenyl)-3-(morpholine-4-yl) propylidene] hydrazine dihydrochlorides, N4 in N-series and N, N’-bis[1-(4-hydroxyphenyl)-3-(pyrrolidine-1-yl) propylidene] hydrazine dihydrochlorides, R4 in R-series were againts AChE with the K-i values of 119 +/- 20 nM, 88 +/- 14 nM, respectively.
