A simple synthesis of nitriles from aldoximes

Easily synthesized aldoximes have been converted to the corresponding nitriles under very mild conditions by a simple reaction with lH-benzotriazol-l-yloxytris(dimethylamino)phosphonium hexafluorophosphate (BOP) and DBU in CH2CI2, THF, or DMF. As an alternative reagent that eliminates the formation of hexamethylphosphoramide as a byproduct, use of lH-benzotriazol-lyl-4-methylbenzenesulfonate (Bt-OTs) and DBU was investigated. Reactions with this reagent also proceeded smoothly and in good yields, although in one case N-sulfonylation was observed. An attempt to gain mechanistic insight into the BOP-mediated reaction has been made using 31P{ 1H} NMR. However, no phosphorus-bearing intermediate could be readily observed. Finally, the method has been applied to the synthesis of an antiviral 4′-cyano adenosine analogue from a commercial precursor using a single saccharide protecting group.

Novel phthalamides containing sulfiliminyl moieties and derivatives as potential ryanodine receptor modulators

To tackle the serious challenge of insect resistance and stricter environmental regulations, innovating a new eco-friendly insecticide is urgently required. A series of new phthalamides containing sulfiliminyl and sulfoximinyl moieties were designed and synthesized. In total, 30 new structures were characterized by 1H NMR spectra and HRMS. The bioassay results indicated that some title compounds exhibited excellent insecticidal activities against oriental armyworm (Pseudaletia separata Walker) and diamondback moth (Plutella xylostella (L.)). 4a showed the same larvicidal level as that of commercial flubendiamide as a control. 7a and 9a exhibited outstanding activity against diamondback moth. The LC50 values of 7a and 9a were 8.33 ¡Á 10-8 and 2.34 ¡Á 10-8 mg L-1, respectively, lower than that of flubendiamide (1.25 ¡Á 10-7 mg L-1). The effects of 4a, 7a and 9a on intracellular calcium of neurons from the beet armyworm (Spodoptera exigua) indicated that these title compounds activate the receptor-operated calcium channel. The calcium ions efflux from the calcium store on endoplasmic reticulum (ER) when treated with novel compounds. The results of CoMFA calculation showed that N-cyanosulfilimines and N-trifluoroacetylsulfoximines might be of importance to the larvicidal activity. The present work demonstrated that structures containing sulfiliminyl and sulfoximinyl moieties can be considered as lead compounds for the development of new insect ryanodine receptor modulators.

Implications of promiscuous Pim-1 kinase fragment inhibitor hydrophobic interactions for fragment-based drug design

We have studied the subtleties of fragment docking and binding using data generated in a Pim-1 kinase inhibitor program. Crystallographic and docking data analyses have been undertaken using inhibitor complexes derived from an in-house surface plasmon resonance (SPR) fragment screen, a virtual needle screen, and a de novo designed fragment inhibitor hybrid. These investigations highlight that fragments that do not fill their binding pocket can exhibit promiscuous hydrophobic interactions due to the lack of steric constraints imposed on them by the boundaries of said pocket. As a result, docking modes that disagree with an observed crystal structure but maintain key crystallographically observed hydrogen bonds still have potential value in ligand design and optimization. This observation runs counter to the lore in fragment-based drug design that all fragment elaboration must be based on the parent crystal structure alone.

Design, synthesis and antiproliferative activity against human cancer cell lines of novel benzo-, benzofuro-, azolo- and thieno-1,3-thiazinone resorcinol hybrids

In this paper we report the design and synthesis of novel derivatives of the 4H-3,1-benzothiazinone type and heterocyclic analogues, i.e. benzofuro-, azolo- and thieno-1,3-thiazin-4-ones possessing 2,4-dihydroxyphenyl substituent. The compounds were obtained by the one-step reaction of aminobenzamides or heterocyclic aminocarboxamides with aryl-modified sulfinylbis[(2,4-dihydroxyphenyl)methanethione]. Evaluation of their antiproliferative potency against human cancer cell lines showed that the activity of some analogues was similar to that of cisplatin. The highest activity and low toxicity were found for 6-tert-butyl-2-(5-chloro-2,4-dihydroxyphenyl)-4H-thieno[3,2-d][1,3]thiazin-4-one. The structure?activity elucidation reveals that the most active compounds are those with a thienothiazin-4-one and benzofuro[3,2-d][1,3]thiazin-4-one skeleton and the presence of the hydrophobic substituent (Et, Cl) in the benzenediol moiety increases their antiproliferative potency. The ADMET properties of selected compounds including metabolic stability and toxicity profile were estimated in silico.

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.

Synthesis of imidazopyridine-fused indoles via one-pot sequential Knoevenagel condensation and cross dehydrogenative coupling

A simple and efficient strategy for the synthesis of imidazopyridine-fused indoles has been developed that involves one-pot sequential Knoevenagel condensation of readily available active methylene azoles with N-substituted-1H-indole-3-carboxaldehydes or N-substituted-1H-indole-2-carboxaldehydes followed by palladium-catalyzed intramolecular cross dehydrogenative coupling reaction. A series of 36 derivatives was prepared by using this strategy. The products were obtained in moderate to excellent (32-94%) yields and showed broad substrate scope with tolerance of various functional groups and was amiable for gram scale preparation without problems.

Radiosynthesis and evaluation of an 18F-labeled positron emission tomography (PET) radioligand for metabotropic glutamate receptor subtype 4 (mGlu4)

Four 4-phthalimide derivatives of N-(3-chlorophenyl)-2-picolinamide were synthesized as potential ligands for the PET imaging of mGlu4 in the brain. Of these compounds, N-(3-chloro-4-(4-fluoro-1,3-dioxoisoindolin-2-yl)phenyl)-2-picolinamide (3, KALB001) exhibited improved binding affinity (IC50 = 5.1 nM) compared with ML128 (1) and was subsequently labeled with 18F. When finally formulated in 0.1 M citrate buffer (pH 4) with 10% ethanol, the specific activity of [18F]3 at the end of synthesis (EOS) was 233.5 ¡À 177.8 GBq/mumol (n = 4). The radiochemical yield of [18F]3 was 16.4 ¡À 4.8% (n = 4), and the purity was over 98%. In vivo imaging studies in a monkey showed that the radiotracer quickly penetrated the brain with the highest accumulation in the brain areas known to express mGlu4. Despite some unfavorable radiotracer properties like fast washout in rodent studies, [18F]3 is the first 18F-labeled mGlu4 radioligand, which can be further modified to improve pharmacokinetics and brain penetrability for future human studies.

Catalytic Enantioselective Synthesis of Highly Functionalized Difluoromethylated Cyclopropanes

The first catalytic asymmetric synthesis of highly functionalized difluoromethylated cyclopropanes is described. The method, based on a rhodium-catalyzed cyclopropanation of difluoromethylated olefins, gives access to a broad range of cyclopropanes bearing ester, ketone, or nitro functional groups. By using Rh2((S)-BTPCP)4 as a catalyst, the corresponding products were obtained in high yields and high diastereo- and enantioselectivities (up 20:1 d.r. and 99 % ee). This methodology allowed preparation of enantioenriched difluoromethylcyclopropanes for the first time.
