Herein, we first present a nickel-catalyzed arylation and alkenylation of tert-cyclobutanols with aryl/alkenyl triflates via a C-C bond cleavage. An array of.-substituted ketones was obtained in moderate-to-good yields, thus featuring earth-abundant nickel catalysis, broad substrate scope, and simple reaction conditions. Preliminary mechanistic experiments indicated that beta-carbon elimination pathways might be involved in the catalytic cycle.

In our efforts to identify novel chemical scaffolds for the development of antileishmanial agents, a series of quinoline metronidazole hybrid compounds was synthesized and tested against the murine model of visceral leishmaniasis. Among all synthesized derivatives, 15b and 15i showed significant antileishmanial efficacy against both extracellular promastigote (IC50 9.54 and 5.42 mu M, respectively) and intracellular amastigote (IC50 9.81 and 3.75 mu M, respectively) forms of Leishmania donovani with negligible cytotoxicity toward the host 0774 macrophages, Vero cells). However, compound 15i effectively inhibited the parasite burden in the liver and spleen (>80%) of infected BALB/c mice. Mechanistic studies revealed that 15i triggers oxidative stress which induces bioenergetic collapse and apoptosis of the parasite by decreasing ATP production and mitochondrial membrane potential. Structure activity analyses and pharmacokinetic studies suggest 15i as a promising antileishmanial lead and emphasize the importance of quinoline metronidazole series as a suitable platform for the future development of antileishmanial agents.

Optimization of a modified Grimmel’s method for N-heterocyclization of a leucine-linked sulfonamide side-arm at position 2 leading to 2,3-disustituted-4-quinazolin-(3H)-ones was accomplished. Further, 22 hybrid quinazolinone motifs (4a-v) were synthesized by N-heterocyclization reaction under microwave irradiation using the ionic liquid [Bmim][BF4]-H2O as green solvent as well as the catalyst. The in vitro screening of the hybrid entities against the malarial species Plasmodium falciparum yielded five potent molecules 4l, 4n, 4o, 4t, and 4u owning antimalarial activity comparable to those of the reference drugs. In continuation, an in silico study was carried out to obtain a pharmacophoric model and quantitative structure-activity relationship. We also built a 3D-QSAR model to procure more information that could be applied to design new molecules with more potent Pf-DHFR inhibitory activity. The designed pharmacophore was recognized to be more potent for the selected molecules, exhibiting five pharmacophoric features. The active scaffolds were further evaluated for enzyme inhibition efficacy against alleged receptor Pf-DHFR computationally and in vitro, proving their candidature as lead dihydrofolate reductase inhibitors, and the selectivity of the test candidates was ascertained by toxicity study against Vero cells. Good oral bioavailability was also proved by studying pharmacokinetic properties.

With the aim of expanding the scope of SAR on piperlongumine (PL), a naturally occurring anticancer molecule, we have designed a novel hybrid molecule bearing 3,4-dihydroisoquinolin-1(2H)-one and trans-cinnamic acids. The structure, based on hybridization strategy, is used for hybridization of naturally occurring scaffolds. We have synthesized 14 hybrid molecules by coupling 3,4-dihydroisoquinolin-1(2H)-one core with cinnamic acids using the mix anhydride approach. The newly synthesized inhibitors were evaluated for cell viability against breast cancer MCF-7 and cervical cancer HeLa cell lines. Furthermore, the active compounds were screened for their potential in breast cancer MDA-MB-231, cervical cancer C33A cell lines, prostate cancer DU-145, PC-3, and normal VERO cells. From the series, compound 10g was seen to inhibit MCF-7 cell growth significantly with GI(50) < 0.1 mu M along with growth inhibition in MDA-MB-231 (GI(50) = 20 mu M) and C33A (GI(50) = 3.2 mu M). While the inhibitor 10i inhibits MCF-7 breast cancer cell growth GI(50) = 3.42 mu M along with inhibition of cell growth in MDA-MB-231 (GI(50) = 30 mu M), HeLa (GI(50) = 7.67 mu M), C33A (GI(50) = 13 mu M), DU-145 (GI(50) = 6.45 mu M), PC-3 (GI(50) = 8.68 mu M), and VERO (GI(50) = 2.93 mu M), respectively. Furthermore, molecular docking study demonstrated these compounds could bind tightly to the colchicine domain of tubulin through a network of favorable steric and electrostatic interactions and thus act as a tubulin polymerization inhibitor.

We describe herein an alternative transition-metal-free procedure to access 3,4-bis(butylselanyl)selenophenes and the so far unprecedented 3-(butylselanyl)-4-alkoxyselenophenes. The protocol involves the 5-endo-dig electrophilic cyclization of 1,3-diynes promoted by electrophilic organoselenium species, generated in situ through the oxidative cleavage of the Se-Se bond of dibutyl diselenide using Oxone(R) as a green oxidant. The selective formation of the title products was achieved by controlling the solvent identity and the amount of dibutyl diselenide. By using 4.0 equiv of dibutyl diselenide and acetonitrile as solvent at 80 degrees C, four examples of 3,4-bis(butylselanyl)selenophenes were obtained in moderate to good yields (40-78%). When 3.0 equiv of dibutyl diselenide were used, in the presence of aliphatic alcohols as solvent/nucleophiles under reflux, 10 3-(butylselanyl)-4-alkoxyselenophenes were selectively obtained in low to good yields (15-80%).

Compared with the ever-growing list of nonprochiral nucleophiles in Ir-catalyzed asymmetric allylic substitution reactions, prochiral nucleophiles are less studied. We present a new prochiral nucleophile, namely, deconjugated butyrolactam, for Ir-catalyzed asymmetric allylic alkylation (AAA). This reaction provides access to a-allyl deconjugated butyrolactams with a moderate to good dr and an excellent er. This is the first AAA reaction of deconjugated butyrolactams. Allyl transposition through Cope rearrangement appears to proceed stereospecifically to form.-allyl conjugated butyrolactams.

A recyclable organic photoreductant (1 mol % CBZ6)-catalyzed reductive (pinacol) coupling of aldehydes, ketones, and imines has been developed. Irradiated by purple light (407 nm) using triethylamine as an electron donor, a variety of 1,2-diols and 1,2-diamines could be prepared. The oxidation potential of the excited state of CBZ6 is established as -1.92 V (vs saturated calomel electrode (SCE)). The relative high reductive potential enables the reductive coupling of carbonyl compounds and their derivatives. CBZ6 can be prepared in gram scale and is acid/base- or air-stable. It could be applied in large-scale photoreductive synthesis and recovered in high yield after the reaction.

Great efforts have been made to enhance the efficiency of the solar light-activated photocatalyst in recent years. In this work, monodispersed copper nanoclusters protected by N-acetyl-L-cysteine ligand (Cu@NALC) were synthesized. The optical properties and chemical composition of the synthesized copper clusters were studied by UV-vis and FTIR spectroscopies, and thermogravimetric analysis (TGA), respectively. The charge of copper atoms in Cu@NALC clusters was zero as was confirmed by X-ray photoelectron spectroscopy (XPS). A novel nanocomposite consisting of similar to 1 nm copper clusters, Degussa TiO2 P25, and activated carbon (Cu@NALC/TiO2/AC) was prepared to use as a solar light-activated photocatalyst. The synthesized copper clusters showed significantly increase solar light absorption and improved the efficiency of Cu@NALC/TiO2/AC nanocomposite for photocatalytic oxidation of benzyl alcohol (BA), compared with Cu@NALC/AC and TiO2/AC nanocomposites. Cu@NALC clusters induce the TiO2 to absorb the visible light, where the copper nanoclusters absorb visible light from 400-700 nm. The copper clusters mainly adsorb on the surface of TiO2 nanoparticles, as well on the activated carbon surface as shown in HR-TEM analysis. The highly efficient photocatalytic activity of this nanocomposite is attributed also to the large surface area of activated carbon as shown in surface area analysis (692.8 m(2)/g). Cu@NALC/TiO2/AC nanocomposite achieved 100% conversion of BA with >= 99 % selectivity after 6 h solar irradiation; however Cu@NALC/AC, TiO2/AC and TiO2 -P25 showed only 66.35 %, 55.43 % and 44.78 %, respectively. All the components of this nanocomposite are cheap and available, in addition to the high photocatalytic activity, were found to be the most economically and suitable system for the industrial application.
