A combined experimental and DFT computations study of novel (E)-3-(benzofuran-2-yl)-2-(thiophen-2-yl)acrylonitrile(TACNBNF): Insight into the synthesis, single crystal XRD, NMR, vibrational spectral analysis, in vitro antioxidant and in silico molecular docking investigation with human peroxiredoxin 5 protein

The synthesized (E)-3-(benzofuran-2-yl)-2-(thiophen-2-yl)acrylonitrile (TACNBNF) crystal compound was characterized using FT-IR, 1H and 13C NMR analyses, ESI-mass and photoluminescence studies. Single crystal X-ray diffraction investigations reveal that the molecule is associated with the C (7)?H (7) ? S (1) donor-acceptor hydrogen bond interaction. The bond angle at C7 gives a strong indication that H7?S1 contact is repulsive. However, the C5?C7?C8 bond angle = 128.8 (2) , is distorted due to strain induced by double bond linkage at C5=C7. The computational work such as optimized geometry by Density functional theory (DFT), FT-IR, Molecular electrostatic potential (MEP), Frontier Molecular orbitals (FMOs), Mulliken’s population analysis, Nonlinear optical effects (NLO), and Natural bond orbitals (NBO) were analyzed with the aid of Gaussian 03 program using basic set B3LYP/6?311++G (d,p). The proton 1H and carbon 13C NMR chemical shifts of molecules were simulated by the gauge-independent atomic orbital (GIAO) manner and also compared with experimental 1H and 13C NMR results. The in vitro antioxidant study was carried out in DPPH assay ascorbic acid, a standard drug. The in silico molecular docking, ADMET and toxicity studies were performed by Discovery Studio 4.0.

Palladium-Catalyzed Formylation of Arylzinc Reagents with S-Phenyl Thioformate

The first example of palladium-catalyzed direct formylation of arylzinc reagents using S-phenyl thioformate is reported. The reaction proceeded under mild conditions, allowing high functional group tolerance. In addition, the developed formylation method was used to prepare deuterated and 13C-labeled aryl aldehydes from isotope-labeled S-phenyl thioformates. Moreover, this procedure was applied to an alkenylzinc halide, affording the corresponding enal.

Synthesis and Cytotoxicity of Octahydroepoxyisoindole-7-carboxylic Acids and Norcantharidin?Amide Hybrids as Norcantharidin Analogues

Octahydroepoxyisoindole analogues of norcantharidin were accessed through a Diels?Alder reaction of an amine-substituted furan with maleic anhydride and subsequent reduction of the bicyclo[2.2.1]heptene olefin. Despite retention of the carboxylate and the ether bridgehead known to impart cytotoxic activity to norcantharidin, none of these analogues displayed notable cytotoxicity against the 11 cell lines examined: HT29 (colon), MCF-7 (breast), A2780 (ovarian), H460 (lung), A431 (skin), Du145 (prostate), BE2-C (neuroblastoma), SJ-G2 and U87 (glioblastoma), MIA (pancreatic), and SMA (spontaneous murine astrocytoma). The incorporation of an amino-substituted system post-synthesis of norcantharidin afforded facile access to 14 acid/amide-substituted norcantharidin analogues. Of these, only four displayed sufficient activity at the initial 25 mum compound screening dose to warrant full evaluation of growth inhibition. Common to these analogues was the presence of a 4-biphenyl moiety, and in particular 3-(2-(furan-2-ylmethyl)-3-(4-biphenylamino)-3-oxopropylcarbamoyl)-7-oxabicyclo[2.2.1]heptane-2-carboxylic acid (13 c) and 3-(2-(pyrrole-2-ylmethyl)-3-(4-biphenylamino)-3-oxopropylcarbamoyl)-7-oxabicyclo[2.2.1]heptane-2-carboxylic acid (24) displayed high levels of cytotoxicity, returning GI50 values of 15 nm (HT29) to 2.9 mum (U87) and 17 nm (SMA) to 2.8 mum (U87), respectively. These are the most cytotoxic norcantharidin analogues reported to date.

Titanium mediated olefination of aldehydes with alpha-haloacetates: An exceptionally stereoselective and general approach to (Z)-alpha-haloacrylates

An exceptionally stereoselective and general synthesis of (Z)-alpha-haloacrylates, ready to undergo various synthetic transformations, has been demonstrated from alpha-haloacetates and aldehydes in a one-pot manner via the titanium-enolate based asymmetric aldol condensation. Besides being an expedient synthetic procedure, the ready availability of diverse alpha-haloacetates, exceptional stereoselectivity, and high yields make the process a versatile transformation in organic synthesis. The potential of this method in up-scaling operations has been illustrated.

Synthesis and biological activity of novel 1-((benzofuran-2-yl)methyl)- 1Htriazole derivatives

A series of novel 1-((benzofuran-2-yl)methyl)-1H-triazole derivatives has been synthesized and tested in vitro against a panel of five different human tumor cell lines. The results show that the existence of benzotriazole or 1,2,3- triazole ring and substitution of the triazolyl-3-position with a naphthylacyl, 4-bromophenacyl or 4-methylbenzyl group could be crucial for promoting cytotoxic activity. Compounds 18, 19, 20 and 25 were found to have the most potent activities selectively against HL-60, SMMC-7721 and MCF-7 cell lines respectively. In particular, compound 20 was more selective towards HL-60 and A549 cell lines with IC50 values of 0.62 and 1.60 muM.

4-Fluoro-3?,4?,5?-trimethoxychalcone as a new anti-invasive agent. From discovery to initial validation in an in vivo metastasis model

Invasion and metastasis are responsible for 90% of cancer-related mortality. Herein, we report on our quest for novel, clinically relevant inhibitors of local invasion, based on a broad screen of natural products in a phenotypic assay. Starting from micromolar chalcone hits, a predictive QSAR model for diaryl propenones was developed, and synthetic analogues with a 100-fold increase in potency were obtained. Two nanomolar hits underwent efficacy validation and eADMET profiling; one compound was shown to increase the survival time in an artificial metastasis model in nude mice. Although the molecular mechanism(s) by which these substances mediate efficacy remain(s) unrevealed, we were able to eliminate the major targets commonly associated with antineoplastic chalcones.

Synthesis, anticancer activity and molecular docking studies on a series of heterocyclic trans-cyanocombretastatin analogues as antitubulin agents

A series of heterocyclic combretastatin analogues have been synthesized and evaluated for their anticancer activity against a panel of 60 human cancer cell lines. The most potent compounds were two 3,4,5-trimethoxy phenyl analogues containing either an (Z)-indol-2-yl (8) or (Z)-benzo[b]furan-2-yl (12) moiety; these compounds exhibited GI50 values of <10 nM against 74% and 70%, respectively, of the human cancer cell lines in the 60-cell panel. Compounds 8, and 12 and two previously reported compounds in the same structural class, i.e. 29 and 31, also showed potent anti-leukemic activity against leukemia MV4-11 cell lines with LD50 values Combining double low line 44 nM, 47 nM, 18 nM, and 180 nM, respectively. From the NCI anti-cancer screening results and the data from the in vitro toxicity screening on cultured AML cells, seven compounds: 8, 12, 21, 23, 25, 29 and 31 were screened for their in vitro inhibitory activity on tubulin polymerization in MV4-11 AML cells; at 50 nM, 8 and 29 inhibited polymerization of tubulin by >50%. The binding modes of the three most active compounds (8, 12 and 29) to tubulin were also investigated utilizing molecular docking studies. All three molecules were observed to bind in the same hydrophobic pocket at the interface of ¡À-and 2-tubulin that is occupied by colchicine, and were stabilized by van der Waalsg? interactions with surrounding tubulin residues. The results from the tubulin polymerization and molecular docking studies indicate that compounds 8 and 29 are the most potent anti-leukemic compounds in this structural class, and are considered lead compounds for further development as anti-leukemic drugs.
