Transition metal free hydrolysis/cyclization strategy in a single pot: Synthesis of fused furo N-heterocycles of pharmacological interest

A transition metal free tandem two-step strategy has been developed involving hydrolysis of 2-chloro-3-alkynyl quinoxalines/pyrazines followed by in situ cyclization of the corresponding 2-hydroxy-3-alkynyl intermediates in a single pot leading to fused furo N-heterocycles as potential inhibitors of sirtuins. A representative compound showed promising pharmacological properties in vitro and in vivo.

Ligand-free Pd-catalysed decarboxylative arylation of imidazo[1,2-: A] pyridine-3-carboxylic acids with aryl bromides

A facile ligand-free method for Pd(OAc)2 catalysed decarboxylative arylation of imidazo[1,2-a]pyridine-3-carboxylic acids with hetero(aryl) bromides has been developed. This method is applicable to a variety of (hetero)aryl bromides as coupling partners. Electron withdrawing and donating groups on imidazo[1,2-a]pyridine-3-carboxylic acids are well tolerated. It represents the first general protocol for ligand-free Pd(OAc)2 catalysed decarboxylative arylation of imidazo[1,2-a]pyridine-3-carboxylic acids with (hetero)aryl halides. A few of the compounds synthesized using this protocol showed antibacterial activity against Staphylococcus aureus.

Markers in analytical chemistry

The growing use of markers in analytical literature in the 10 years, 1991-2000, is presented and discussed because of their relevance in modern analytical chemistry. The complementary and contradictory aspects of markers and others related words, such as tracer, indicator, index, labelling compound, etc., are clarified. To offer a general overview, several classifications of markers are outlined. The main distinction between markers is their internal or external fitness for purpose. Selected examples are assessed on this basis.

Synthesis and SAR of highly potent dual 5-HT1A and 5-HT 1B antagonists as potential antidepressant drugs

Novel 5-HT1 autoreceptor ligands based on the N-4-aryl-piperazinyl-N?-ethyl-5,6,7,8-tetrahydropyrido[4?, 3?:4,5]thieno[2,3-d]pyrimidin-4(3H)-one core are described. Aiming at antidepressants with a novel mode of action our objective was to identify potent antagonists showing balanced affinities and high selectivity for the 5-HT 1A and 5-HT1B receptors. Strategies for the development of dual 5-HT1A and 5-HT1B antagonists based on 1 and 2 as leads and the corresponding results are discussed. Isoquinoline analogue 33 displayed high affinity and an antagonistic mode of action for the 5-HT 1A and the 5-HT1B receptors and was characterized further with respect to selectivity, electrically stimulated [3H]5-HT release and in vivo efficacy.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 35700-40-4, help many people in the next few years.35700-40-4

Aminoguanidine hydrazone derivatives as non-peptide NPFF1 receptor antagonists reverse opioid induced hyperalgesia

Neuropeptide FF receptors (NPFF1R and NPFF2R) and their endogenous ligand Neuropeptide FF have been shown previously to display anti-opioid properties and to play a critical role in the adverse effects associated with chronic administrations of opiates including the development of opioid-induced hyperalgesia and analgesic tolerance. In this work, we sought to identify novel NPFF receptors ligands by focusing our interest on a series of heterocycles as rigidified non-peptide NPFF receptor ligands, starting from already described aminoguanidine hydrazones (AGH’s). Binding experiments and functional assays highlighted AGH 1n and its rigidified analog 2-amino-dihydropyrimidine 22e for in vivo experiments. As earlier shown with the prototypical dipeptide antagonist RF9, both 1n and 22e reduced significantly the long lasting fentanyl-induced hyperalgesia in rodents. Altogether these data indicate that AGH rigidification maintains nanomolar affinities for both NPFF receptors, while improving antagonist character towards NPFF1R.

Chemoselective Cross-Coupling between Two Different and Unactivated C(aryl)-O Bonds Enabled by Chromium Catalysis

We report here the first example of cross-coupling between two different and unactivated C(aryl)-O bonds with chromium catalysis. The combination of a low-cost Cr(II) salt, 4,4?-di-tert-butyl-2,2?-dipyridyl (dtbpy) as the ligand, and magnesium as the reductant shows high reactivity in promoting the reductive cross-coupling of aryl methyl ether derivatives with aryl esters by cleavage and coupling of two different C(aryl)-O bonds under mild conditions. The formation of active low-valent Cr species by reduction of CrCl2 with Mg can be considered, which prefers to initially activate the C(aryl)-O bond of phenyl methyl ether with the chelation help of dtbpy and an o-imine auxiliary. The subsequent consecutive reduction, second C(aryl)-O activation, and reductive elimination allow for the achievement of selective cross-coupling of C(aryl)-O/C(aryl)-O bonds.
