Synthesis of terminal alkynes based on (1S,3R,4R)- and (1S,3S,4R)-2-azabicyclo[2.2.1]heptane

Two approaches to terminal alkynes based on the enantiomerically pure epimers (1S,3R,4R)- and (1S,3S,4R)-2-azabicyclo[2.2.1]heptane aldehydes were established: i) a non-Wittig route through a dichloroalkene intermediate; and, ii) a Corey-Fuchs approach via dibromoalkene. Among various organometallic reagents tested, the use of n-butyllithium was efficient. The resulting alkynes were fully characterized, and one epimer was used in a click chemistry triazole synthesis. For one of the products containing a bulky N-Boc-proline substituent, the existence of atropisomers was observed. The absolute stereochemistry was determined by electronic circular dichroism spectroscopy (ECD) and optical rotation supported by quantum chemical simulations.

Multifaceted activity of polyciclic MDR revertant agents in drug-resistant leukemic cells: Role of the spacer

A small library of derivatives carrying a polycyclic scaffold recently identified by us as a new privileged structure in medicinal chemistry was designed and synthesized, aiming at obtaining potent MDR reverting agents also endowed with antitumor properties. In particular, as a follow-up of our previous studies, attention was focused on the role of the spacer connecting the polycyclic core with a properly selected nitrogen-containing group. A relevant increase in reverting potency was observed, going from the previously employed but-2-ynyl- to a pent-3-ynylamino moiety, as in compounds 3d and 3e, while the introduction of a triazole ring proved to differently impact on the activity of the compounds. The docking results supported the data obtained by biological tests, showing, for the most active compounds, the ability to establish specific bonds with P-glycoprotein. Moreover, a multifaceted anticancer profile and dual in vitro activity was observed for all compounds, showing both revertant and antitumor effects on leukemic cells. In this respect, 3c emerged as a triple-target agent, endowed with a relevant reverting potency, a considerable antiproliferative activity and a collateral sensitivity profile.

Heterobimetallic Carbene Complexes Bearing Cyclometalated Ir-III/Rh-III and Mixed NHC boolean AND Py/PPh3 Coordinated Pd-II Centers: Structures and Tandem Catalysis

Heterobimetallic complexes bearing NHC donor ligands are gaining immense popularity in organometallic chemistry and tandem catalysis. It is known that the NHC reacts with Pd-II in the presence of pyridine to yield PEPPSI type complexes and the NHC ligands having ortho-C-H proton easily orthometalate to Ir-III or Rh-III centers. Combining these two methodologies in a stepwise fashion, we present here a series of heterobimetallic Ir-III-Pd-II and Rh-III-Pd-II complexes from a dicarbene donor ligand featuring cyclometalated Ir-III or Rh-III and mixed NHC perpendicular to Py /PPh3 coordinated Pd-II centers. All the heterobimetallic complexes have been structurally characterized by X-ray crystallographic analysis. The heterobimetallic complexes featuring mixed NHC perpendicular to PPh3 coordinated Pd-II centers show better activity in tandem Suzuki-Miyaura/transfer hydrogenation reactions compared to both, the heterobimetallic complexes possessing PEPPSI type Pd(II)centers, and the equimolar mixture of their mononuclear Pd-II and Rh-III or Ir-III counterparts. The heterobimetallic complex featuring cyclometalated Ir-III and mixed NHC perpendicular to PPh3 coordinated Pd-II center shows excellent selectivity for 4-biphenylmethanol (isolated yield: 92 %) in tandem catalysis.

Pyridinyl-triazole ligand systems for highly efficient CuI-catalyzed azide- alkyne cycloaddition

Pyridinyl-triazole ligand systems (including N-2-2-pyridinyl 1,2,3-triazoles and N-1/N-2-substituted 2-(NH-1,2,3triazol-4-yl)pyridines) were found to be superior ligands for CuI-catalyzed azide-alkyne cycloaddition (CuAAC) reactions. Low catalyst loadings, short reaction times, facile catalyst recyclability, ambient temperature, and open-flask conditions made this catalytic system very practical. The iodide anions could form iodine bridges to construct stable dinuclear Cu(I) complexes with these ligands, which was the key to achieve high catalytic activities. While CuBr and CuCl were not suitable for this ligand system because of the improper size of Br and Cl atoms for the formation of the corresponding dinuclear Cu(I) complexes.

Electrosynthesis of silver metal nanocomposites in a copolymer matrix of 1-vinyl-1,2,4-triazole and acrylic acid

Nanocomposites and silver nanocomposite coatings based on a copolymer of 1-vinyl-1,2,4-triazole and acrylic acid were synthesized in an aqueous and aqueous-ethanol medium on pure iron and steel electrodes by the electrochemical method. The composition and structure of nanocomposites is confirmed by UV, IR spectroscopy, X-ray diffraction analysis, transmission electron microscopy, thermogravimetric method, etc. It was found that the solubility of nanocomposites depends on the concentration of silver particles in the (co) polymer matrix. Stage by stage thermal decomposition of nanocomposites takes place.

Design and In Silico Study of the Novel Small Molecular MDM2 Inhibitors

Protein-protein Interaction (PPIs) plays a central role in many diseased conditions. Therefore to target and to modulate PPIs is an efficient approach for the disease treatment. Cancer is also arising because of Protein-protein interaction. In cancer, the tumor suppressor p53 protein got inhibited by the MDM2 protein. p53 protein regulates the cell cycle and apoptosis. Interaction between the p53-MDM2 proteins is responsible for the inhibition of the p53 function. By this interaction, MDM2 degrades and inhibits the p53 protein. Hence, to target and inhibit the p53-MDM2 interaction for the treatment of cancer is the rational approach. By targeting this interaction with the drugs, we can selectively kill the cancer cells over the normal cells. Recently, p53-MDM2 interaction inhibitor drugs have been reported by many researchers and pharmaceutical companies. And several drugs entered into the clinical trials. In this study, a novel 1,2,4-triazole based molecules were designed as MDM2 inhibitors and performed their in-silico study. We designed the novel compound 01 and Lead 1a. In this work, In silico study of the Lead 1a and reference compounds (Nutlin 3a, RG7112) was carried out. The molecular docking study of the Novel 1,2,4-triazole based lead 1a and reference compounds was carried out. The docking score of the Lead 1a found to be better than Nutlin 3a and close to RG7112. The various possible conformations and binding affinity values were also determined by the docking study. These results indicate the Lead 1a as a potential MDM2 inhibitor and anti-cancer agent.

Magnetic metal-organic framework MIL-100 (Fe)/polyethyleneimine composite as an adsorbent for the magnetic solid-phase extraction of fungicides and their determination using HPLC-UV

Fe3O4@MIL-100 (Fe)/PEI are used for the first time as an adsorbent material for the extraction of pesticide residues (epoxiconazole, flusilazole, tebuconazole, and triadimefon) from food matrices. The adsorbent proposed (Fe3O4@MIL-100(Fe)/PEI) was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), field emission scanning electron microscopy (FE-SEM), thermogravimetric (TG) analysis, and vibrating sample magnetometer (VSM) techniques to evaluate the properties of the sorbent. Then, the Fe3O4@MIL-100 (Fe)/PEI was employed for the quantification of the four triazole fungicides in fruits and vegetables (apple, orange, tomato, cabbage, and cucumber) using HPLC-UV for separation and detection. During the extraction process, the main parameters such as amount of adsorbent, extraction time, pH value, ionic strength, eluting solvent, and eluting volume were optimized. Under the optimum conditions, good linearity of this method was observed for all analytes, with correlation coefficients (R-2)>= 0.9908. The limits of detection (LODs) ranged from 0.021-3.04 mu g kg(-1). The extraction recoveries of the four triazole fungicides varied from 73.9 to 109.4% with relative standard deviations (RSD) in the range 0.5 to 6.2%. Compared with other MOFs, the modification of Fe3O4@MIL-100 (Fe) with PEI shows high efficient adsorption due to the combined benefits of MIL-100 (Fe) and PEI. The material is easily synthesized, has good stability, and is of low cost.

Iridium-Catalyzed Direct Amidation of Imidazoles at the C-2 Position with Isocyanates in the Presence of Hydrosilanes Leading to Imidazole-2-Carboxamides

Regioselective coupling reaction of N-substituted imidazoles with isocyanates in the presence of a stoichiometric amount of hydrosilanes catalyzed by Ir-4(CO)(12) to give imidazole-2-carboxamides is reported. Imidazoles bearing an (O-silyl)carboximidate group at the 2-position appear to be initially formed in the reaction; these are then hydrolyzed to the final products in situ. The addition of the hydrosilane was essential for the catalytic reaction to proceed. Substituents on the imidazole ring had no effect on the reaction, except for certain bulky substituents such as tBu and Ph groups at the 4-position. Triazoles such as 4-methyl-4H-1,2,4-triazole and 1-methyl-1H-1,2,4-triazole were also applicable to this C-H amidation, and the latter reaction proceeded regioselectively at the carbon atom between the sp(3) and sp(2) nitrogen atoms of the ring, and not between the two sp(2) nitrogen atoms.

Facile synthesis of magnetic molybdenum disulfide@graphene nanocomposite with amphiphilic properties and its application in solid-phase extraction for a wide polarity of insecticides in wolfberry samples

A novel magnetic molybdenum disulfide@graphene (Fe3O4/MoS2@G) nanocomposite with amphiphilic properties was prepared via a co-mixing solvothermal method. To demonstrate the feasibility of Fe3O4/MoS2@G as a sorbent during sample preparation, it was employed for the magnetic solid phase extraction (MSPE) of ten pyrethroids, three triazoles and two acaricide pyridaben and picoxystrobin in an emulsified aqueous solution. Dichloromethane was used as the extractant to form an emulsified aqueous solution. Subsequently, the Fe3O4/MoS2@G sorbent with amphiphilic properties was used to retrieve 15 wide polarity insecticides from dichloromethane via MSPE. The proposed method has the advantage of being applicable to different polar pesticides, strengthening the capacity of enrichment and purification of target analytes. The pi-pi interaction between the hydrophilic and hydrophobic moieties of Fe3O4/MoS2@G and the aromatic rings of target analytes were responsible for the efficient sorption. Thus, a reliable, convenient, and efficient method for the analysis of 15 insecticides with wide polarity in wolfberry samples was established by coupling Fe3O4/MoS2@G nanocomposite MSPE with gas chromatography-mass spectrometry (GC-MS) analysis. The obtained linearity of this method was in the range from 1 to 5000 ng mL(-1) for 15 analytes, with determination coefficients (R-2) >= 0.9907. The limit of detection (LOD) for 15 insecticides was in the range from 0.1 to 5.0 ng g(-1). The recoveries of 15 insecticides from spiked wolfberry samples were in the range from 71.41% to 110.53%, and RSD was less than 14.8%.

Waste-minimized synthesis of C2 functionalized quinolines exploiting iron-catalysed C-H activation

Herein we present an efficient and regioselective iron-catalyzed methodology for the external oxidant-free functionalization of quinoline-N-oxides. The protocol, based on the use of inexpensive and easily accessible FeSO4, showed broad applicability to a wide range of substrates. An additional green feature of this synthetic methodology is H2O being the only by-product. Experimental and computational investigations provide support to a mechanism based on a facile C-H activation event. The green efficiency of the process has also been carefully assessed using: (i) metrics related to the synthetic process (AE, Yield, 1/SF, MRP and RME); (ii) safety/hazard metrics (SHZI and SHI); and (iii) metrics related to the metal used as the catalyst (Abundance, OEL and ADP). In addition to the many advantages of this protocol related to the green iron catalyst used and the safety/hazard features of the process, an E-factor value of ca. 0.92 (84 to >99% reduction compared to known protocols) evidently confirms the sustainable efficiency of the procedure presented. Practical utility has also been demonstrated by performing the reaction efficiently on a multi-gram scale.
