Studies on a novel, potent and orally effective cholecystokinin A antagonist, FK-480. Synthesis and structure-activity relationships of FK-480 and related compounds

We prepared various novel tricyclic 1,4-benzodiazepine derivatives as cholecystokinin (CCK) A antagonists, which were evaluated preliminarily for inhibition of 125I-CCK-8 binding to rat pancreatic membranes in vitro and inhibiting effect on CCK-8-induced inhibition of charcoal meal gastric emptying in mice. On the basis of structure-activity relationship (SAR) studies, as well as the stability and availability of the starting materials of those compounds, (S)-N-[1-(2-fluorophenyl)-3,4,6,7-tetrahydro-4-oxo-pyrrolo[3,2,1-jk][1 ,4]benzodiazepin-3-yl]1 H-indole-2-carboxamide (9f, FK-480) was selected as a candidate compound for further evaluation. The absolute configuration of the precursor of FK-480, (3S)-amino-1,4-benzodiazepine derivative ((S)-8a, R1 = F) was determined by an X-ray crystallographic study of its ureido derivative with (S)-alpha-methylbenzyl isocyanate. FK-480 is now undergoing clinical studies for the treatment of chronic pancreatitis.

Copper-Catalyzed C-4 Carboxylation of 1-Naphthylamide Derivatives with CBr4/MeOH

A simple and practical copper catalyzed C-4 carboxylation reaction of 1-naphthylamide derivatives using carbon tetra bromide and methanol is reported here. Picolinamide and its derivatives are used as a bidentate directing group for the distal C4-H functionalization. Various substituted naphthylamide derivatives, and anilides are employed for the carboxylation and proceeds in good yields under mild condition. From the outcome of experimental results, it is proposed that C4-H carboxylation reaction of 1-naphthylamides might proceed through a single electron transfer (SET) pathway. (Figure presented.).

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 486-73-7 is helpful to your research. Electric Literature of 486-73-7

To elucidate the structural, spectroscopic and bonding properties, the theoretical calculations at the DFT level were undertaken for 1, 3, 5 and 7. The synthesized complexes exhibited moderate activity in the oxidation of 1-phenylethanol and certain alkanes (n-heptane and methylcyclohexane) with tert-butyl hydroperoxide (TBHP) in acetonitrile. Chromatograms of products obtained from the alkanes indicated that a sufficient sterical hindrance exists around of the rhenium catalytic center.

Anti-inflammatory and anti-migratory activities of isoquinoline-1-carboxamide derivatives in lps-treated bv2 microglial cells via inhibition of MAPKS/NF-KappaB pathway

Eleven novel isoquinoline-1-carboxamides (HSR1101~1111) were synthesized and evaluated for their effects on lipopolysaccharide (LPS)-induced production of pro-inflammatory mediators and cell migration in BV2 microglial cells. Three compounds (HSR1101~1103) exhibited the most potent suppression of LPS-induced pro-inflammatory mediators, including interleukin (IL)-6, tumor necrosis factor-alpha, and nitric oxide (NO), without significant cytotoxicity. Among them, only N-(2-hydroxyphenyl) isoquinoline-1-carboxamide (HSR1101) was found to reverse LPS-suppressed anti-inflammatory cytokine IL-10, so it was selected for further characterization. HSR1101 attenuated LPS-induced expression of inducible NO synthase and cyclooxygenase-2. Particularly, HSR1101 abated LPS-induced nuclear translocation of NF-kappaB through inhibition of IkappaB phosphorylation. Furthermore, HSR1101 inhibited LPS-induced cell migration and phosphorylation of mitogen-activated protein kinases (MAPKs) including extracellular signal-regulated kinase 1/2, c-Jun N-terminal kinase, and p38 MAPK. The specific MAPK inhibitors, U0126, SP600125, and SB203580, suppressed LPS-stimulated pro-inflammatory mediators, cell migration, and NF-kappaB nuclear translocation, indicating that MAPKs may be the upstream kinase of NF-kappaB signaling. Collectively, these results demonstrate that HSR1101 is a potent and promising compound suppressing LPS-induced inflammation and cell migration in BV2 microglial cells, and that inhibition of the MAPKs/NF-kappaB pathway mediates its anti-inflammatory and anti-migratory effects. Based on our findings, HSR1101 may have beneficial impacts on various neurodegenerative disorders associated with neuroinflammation and microglial activation.

Synthesis and evaluation of novel 8,5-fused bicyclic peptidomimetic compounds as interleukin-1beta converting enzyme (ICE) inhibitors

An 8,5-fused bicyclic peptidomimetic ring system generated by a stereoselective ring metathesis reaction was elaborated into potent inhibitors of interleukin-1beta converting enzyme (ICE, caspase-1). Multiple compounds were found that exhibited ICE IC50 values <10 nM and were selective over caspase-3 and caspase-8. These active analogs generally possessed good activity (IC50 values <100 nM) in a whole cell assay measuring IL-1beta production. Pharmacokinetic analysis of the ethyl acetal prodrug form of a selected active lead revealed a compound with a reasonable plasma half-life (1.1 h) and good oral bioavailability (30%).

Synthesis and Crystal Structures of [(Nicotinic Acid)2H] +I-, [(2-Amino-6-methylpyridine)H]+(NO 3)-, and the 1:1 Complex Between 1-Isoquinoline Carboxylic Acid (Zwitter Ion) and L-Ascorbic Acid Assembled via Hydrogen Bonds

Three new complexes, namely [(nicotinic acid)2H] +I-, [(2-amino-6-methylpyridine)H]+ (NO 3)-, and the 1:1 complex between 1-isoquinoline carboxylic acid (zwitter ion form) and L-ascorbic acid were synthesized. The IR spectra revealed different types of hydrogen bonds in these compounds. The X-ray structure determination has shown the first compound to consist of a packing of [(nicotinic acid)2H]+ cations and I – anions. In the dimeric cation the two nicotinic acid molecules (zwitter ions) are connected through hydrogen bonds (O-H…O). Each dimer is further engaged in other hydrogen bonds with adjacent dimers giving 2D layers. The I- ion is located at the inversion center. In the second compound the cation and anion are connected via hydrogen bonds formed between oxygen atoms of the NO3- anion and NH and NH2 of the cation generating a layer structure. All atoms are coplanar on mirror planes. In the 1:1 complex the two molecules are connected through hydrogen bonds formed between the two oxygen atoms of the carboxylate group of 1-isoquinoline carboxylic acid (zwitter ion) and the oxygen atoms of the two adjacent hydrogen groups of the L-ascorbic acid molecule. These complex molecules are engaged in other hydrogen bonds with each other forming a 2D system normal to the long b-axis of the unit cell.

Cu2O/1-(2-methylhydrazine-1-carbonyl)-isoquinoline 2-oxide catalyzed C-N cross-coupling reaction in aqueous media

An experimentally simple, efficient, and inexpensive catalyst system was developed for the N-arylation of imidazole, indole, pyrrole, alkyl alcohol amines, and alkyl amines with aryl iodides and bromides. The reaction proceeds in water-ethanol media at 120 C for 12 h with Cu2O as the catalyst, 1-(2-methylhydrazine-1-carbonyl)-isoquinoline 2-oxide (L2) as the ligand, NaOH as the base to generate a wide range of N-arylated products in moderate to excellent yields. Aqueous medium, ease of operation, and broad substrate scope give the process a benign environmental profile.

Aluminum-catalyzed asymmetric alkylations of pyridyl-substituted alkynyl ketones with dialkylzinc reagents

Alkylations of pyridyl-substituted ynones with Et2Zn and Me 2Zn, promoted by amino acid-based chiral ligands in the presence of Al-based alkoxides, afford tertiary propargyl alcohols efficiently in 57% to >98% ee. Two easily accessible chiral ligands are identified as optimal for reactions of the two dialkylzinc reagents. Catalytic alkylations with Et 2Zn require a chiral ligand carrying two amino acid moieties (valine and phenylalanine) along with a p-trifluoromethylphenylamide C-terminus. In contrast, reactions with Me2Zn are most effectively promoted in the presence of a chiral ligand containing a single amino acid (benzyl cysteine), capped by an n-butylamide. Enantiomerically enriched tertiary alcohols bearing a pyridyl and an alkyne substituent can be functionalized in a variety of manners to furnish a wide range of difficult-to-access acyclic and heterocyclic structures; two noteworthy examples are Cu-catalyzed protocols for conversion of tertiary propargyl alcohols to enantiomerically enriched tetrasubstituted allenes and bicyclic amides that bear an N-substituted quaternary carbon stereogenic center. Mechanistic models that account for the trends and enantioselectivity levels are provided.

ELECTROCHEMICAL REDUCTION OF PRISTINAMYCIN IA AND RELATED STREPTOGRAMINS IN AQUEOUS ACIDIC MEDIUM

The electrochemical reduction of the picolinoyl residue of pristinamycinIA and related streptogramins was performed at a mercury cathode, in aqueous medium.The presence of a peptidic lactone residue at the amide nitrogen atom markedly modified the expected cathodic behaviour of pyridyl carboxamides: in particular, we observed the reduction of the pyridyl ring into tetrahydropyridine derivatives.Thanks to a series of model heterocyclic carboxamides, increasing steric hindrance at the amide nitrogen position was shown to lead to enhanced reduction of the heterocyclic ring.
