6,6-Fused heterocyclic ureas as highly potent TRPV1 antagonists

A series of N-[{2-(4-methylpiperidin-1-yl)-6-(trifluoromethyl)-pyridin-3-yl}methyl] N?-(6,6-fused heterocyclic) ureas have been investigated as hTRPV1 antagonists. Among them, compound 15 showed highly potent TRPV1 antagonism to capsaicin, with Ki(ant) = 0.2 nM, as well as antagonism to other activators, and it was efficacious in a pain model. A docking study of 15 with our hTRPV1 homology model indicates that there is crucial hydrogen bonding between the ring nitrogen and the receptor, contributing to its potency.

Phosphine-free palladium-catalyzed decarboxylative coupling of alkynylcarboxylic acids with aryl and heteroaryl halides

We herein report the design and development of a carboxyamido/carbene ligand and its Pd-complex for the decarboxylative coupling of alkynylcarboxylic acids with aryl and heteroaryl halides to afford arylalkynes. Copyright

Design, syntheses, and pharmacological characterization of 17-cyclopropylmethyl-3,14beta-dihydroxy-4,5alpha-epoxy-6alpha-(isoquinoline-3?-carboxamido)morphinan analogues as opioid receptor ligands

A series of 17-cyclopropylmethyl-3,14beta-dihydroxy-4,5alpha-epoxy-6alpha-(isoquinoline-3?-carboxamido)morphinan (NAQ) analogues were synthesized and pharmacologically characterized to study their structure-activity relationship at the mu opioid receptor (MOR). The competition binding assay showed two-atom spacer and aromatic side chain were optimal for MOR selectivity. Meanwhile, substitutions at the 1?- and/or 4?-position of the isoquinoline ring retained or improved MOR selectivity over the kappa opioid receptor while still possessing above 20-fold MOR selectivity over the delta opioid receptor. In contrast, substitutions at the 6?- and/or 7?-position of the isoquinoline ring reduced MOR selectivity as well as MOR efficacy. Among this series of ligands, compound 11 acted as an antagonist when challenged with morphine in warm-water tail immersion assay and produced less significant withdrawal symptoms compared to naltrexone in morphine-pelleted mice. Compound 11 also antagonized the intracellular Ca2+ increase induced by DAMGO. Molecular dynamics simulation studies of 11 in three opioid receptors indicated orientation of the 6?-nitro group varied significantly in the different ‘address’ domains of the receptors and played a crucial role in the observed binding affinities and selectivity. Collectively, the current findings provide valuable insights for future development of NAQ-based MOR selective ligands.

Bright orange/red-emitting rhodium(iii) and iridium(iii) complexes: Tridentate N^C^N-cyclometallating ligands lead to high luminescence efficiencies

Rhodium(iii) complexes rarely display strong phosphorescence, in contrast to well-known iridium(iii) complexes with cyclometallating ligands. This study shows how 1,3-bis(1-isoquinolyl)benzene cyclometallates to Rh(iii) through N^C^N-coordination to give complexes with unprecedented phosphorescence quantum yields at room temperature. Their highly emissive Ir(iii) analogues are also described.

Rh(III)-Catalyzed [4 + 2] Self-Annulation of N-Vinylarylamides

An efficient rhodium(III)-catalyzed self-annulation of N-vinylarylamide has been developed. This reaction features a simple system and good reactivity with complete regioselectivity. The protocol provides easy access to an aminal incorporated dihydroisoquinolinone, which proved to be a versatile synthetic synthon. The kinetic isotope effect experiments showed that C-H activation is the rate-limiting step, and competition studies revealed the annulation exhibits a strong self-recognition mode. In addition, a seven-membered rhodacycle species was isolated and established as the key reaction intermediate.

New luminescent cyclometalated iridium(III) complexes containing fluorinated phenylisoquinoline-based ligands: Synthesis, structures, photophysical properties and DFT calculations

Two new fluorinated phenylisoquinoline-based iridium(III) complexes, [Ir(f2piq)2(bipy)][PF6] (3a) and [Ir(fmpiq)2(bipy)][PF6] (3b) (f2piq = 1-(2,4-difluorophenyl)isoquinoline, fmpiq = 1-(4-fluoro-2-methylphenyl)isoquinoline, bipy = 2,2?-bipyridine), have been synthesized and fully characterized. Single crystal X-ray diffraction study has been undertaken on complexes 3a and 3b, which show that each adopts the distorted octahedral coordination geometry with the cis-C,C? and trans-N,N? configuration. The photoluminescence spectra of 3a and 3b exhibit yellow and orange emission maxima at 584 and 600 nm, respectively. The frontier molecular orbital diagrams and the lowest-energy electronic transitions of 3a-3b have been calculated with density functional theory (DFT) and time-dependent DFT (TD-DFT). The absorption and emission spectra of complex 3b is red-shifted relative to those of complex 3a, as a consequence of the nature of the methyl group.

Asymmetric Synthesis of Isoquinoline Alkaloids: 2004-2015

In the past decade, the asymmetric synthesis of chiral nonracemic isoquinoline alkaloids, a family of natural products showing a wide range of structural diversity and biological and pharmaceutical activity, has been based either on continuation or improvement of known traditional methods or on new, recently developed, strategies. Both diastereoselective and enantioselective catalytic methods have been applied. This review describes the stereochemically modified traditional syntheses (the Pictet-Spengler, the Bischler-Napieralski, and the Pomeranz-Fritsch-Bobbitt) along with strategies based on closing of the nitrogen-containing ring B of the isoquinoline core by the formation of bonds between C1-N2, N2-C3, C1-N2/N2-C3, and C1-N2/C4-C4a atoms. Methods involving introduction of substituents at the C1 carbon of isoquinoline core along with syntheses applying various biocatalytic techniques have also been reviewed.

I2/TBHP mediated multiple C[sbnd]H bonds functionalization of azaarenes with methylarenes to synthesize iodoisoquinolinones via iodination/N-benzylation/amidation sequence

An oxidative multi-functionalization of azaarenes with benzylic C[sbnd]H bonds of methylarenes via iodination/N-benzylation/amidation cascade, to produce N-benzyl-4-iodoisoquinolin-1(2H)-ones and N-benzyl-3-iodoquinolin-2(1H)-ones is developed. The molecular iodine plays a triple role in activating benzylic sp3 C[sbnd]H bond of methylbenzenes, accelerating the oxidation process and serving as iodination reagent. This reaction utilizes cheap and readily available azaarenes and methylarenes as starting materials and proceeds under metal-free conditions to construct C-I, C[sbnd]N and C[dbnd]O bonds consecutively and afford iodo(iso)quinolinones efficiently.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.
