Discovery of N-hydroxy-2-(2-oxo-3-pyrrolidinyl)acetamides as potent and selective inhibitors of tumor necrosis factor-alpha converting enzyme (TACE).

Only registered users can translate articles

New inhibitors of tumor necrosis factor-alpha converting enzyme (TACE) were discovered using an N-hydroxy-2-(2-oxo-3-pyrrolidinyl)acetamide scaffold. The series was found to be potent in a porcine TACE (pTACE) assay with IC(50)s typically below 5 nM. For most compounds, selectivity for pTACE

Discovery of (S)-N-[2-[1-(3-ethoxy-4-methoxyphenyl)-2-methanesulfonylethyl]-1,3-dioxo-2,3-dihydro-1H-isoindol-4-yl] acetamide (apremilast), a potent and orally active phosphodiesterase 4 and tumor necrosis factor-alpha inhibitor.

In this communication, we report the discovery of 1S (apremilast), a novel potent and orally active phosphodiesterase 4 (PDE4) and tumor necrosis factor-alpha inhibitor. The optimization of previously reported 3-(1,3-dioxo-1,3-dihydroisoindol-2-yl)-3-(3,4-dimethoxyphenyl)propionic acid PDE4

Treatment with Y-40138, a multiple cytokine production modulator, inhibits lipopolysaccharide- or tumour necrosis factor-alpha-induced production of pro-inflammatory cytokines and augments interleukin-10.

N-[1-(4-[4-(pyrimidin-2-yl)piperazin-1-yl]methyl phenyl)cyclopropyl] acetamide . HCl (Y-40138) suppresses liver injury in concanavalin A- and D-galactosamine/lipopolysaccharide (LPS)-induced mouse hepatitis models. However, the mechanism of action of Y-40138 has not been fully investigated. In this

A novel cyclin-dependent kinase inhibitor down-regulates tumor necrosis factor-alpha (TNF-alpha)-induced expression of cell adhesion molecules by inhibition of NF-kappaB activation in human pulmonary epithelial cells.

OBJECTIVE To observe the effect of fluoroacetamide on cardiomyocytes of rat and the antidotal effect of acetamide. METHODS 4 groups of SD rats were treated with various dosages of fluoroacetamid(p.o.) and 2 groups of them were treated with acetamide(i.p.). The changes of cardiomyocytes and serum

Protective efficacy of N-(2-hydroxyphenyl) acetamide against adjuvant-induced arthritis in rats.

Only registered users can translate articles

Rheumatoid arthritis is a chronic inflammatory joint disease characterized by synovial proliferation and tissue destruction. Proinflammatory cytokines like interleukin-1beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) play a key role in the disease process and elevate energy expenditure, which

A novel anti-rheumatic drug suppresses tumor necrosis factor-alpha and augments interleukin-10 in adjuvant arthritic rats.

Only registered users can translate articles

Tumor necrosis factor-alpha (TNF-alpha) plays an important role in the pathology of rheumatoid arthritis. When N-[1-(4-¿[4-(pyrimidin-2-yl)piperazin-1-yl]methyl¿phenyl)cycloprop yl] acetamide (Y-39041) (3-30 mg/kg) was orally administered to rats with established arthritis from day 15 to day 20,

Adenocarcinoma of the kidney. IV. Electron microscopic study of the development of renal adenocarcinomas induced in rats by N-(4'-fluoro-4-biphenylyl)acetamide.

Only registered users can translate articles

Ultrastructural features of various stages in the histogenesis of renal adenocarcinoma induced in F344 rats by the carcinogen N-(4'-fluoro-4-biphenylyl)acetamide (FBPA) are described. FBPA was added to the diet up to 48 weeks; animals were killed at intervals from 4 to 52 weeks. Characterized were

A novel dual regulator of tumor necrosis factor-alpha and interleukin-10 protects mice from endotoxin-induced shock.

A pyrimidylpiperazine derivative, N-[1-(4-¿[4-(pyrimidin-2-yl)piperazin-1-yl]methyl¿phenyl)cycloprop yl] acetamide (Y-39041), is a dual cytokine regulator of tumor necrosis factor (TNF)-alpha and interleukin-10 production. Lipopolysaccharide-induced TNF-alpha release in BALB/c mice was inhibited by

The Benzimidazole Derivatives, B1 (N-[(1H-Benzimidazol-2-yl)Methyl]-4-Methoxyaniline) and B8 (N-{4-[(1H-Benzimidazol-2-yl)Methoxy]Phenyl}Acetamide) Attenuate Morphine-Induced Paradoxical Pain in Mice.

Only registered users can translate articles

Despite being routinely used for pain management, opioid use is limited due to adverse effects such as development of tolerance and paradoxical pain, including thermal hyperalgesia and mechanical allodynia. Evidence indicates that continued morphine administration causes increased expression of

Studies on the mechanism of acetamide hepatocarcinogenicity.

The hepatocarcinogen acetamide, in single doses of 100 and 400 mg/kg b.wt., was shown to act as an initiator in a dose-dependent fashion in rat liver using the Solt-Farber method. Acetamide and its putative metabolite N-hydroxy-acetamide did not cause liver necrosis in single dose experiments.

Synthesis and in vivo evaluation of [11C]PJ34, a potential radiotracer for imaging the role of PARP-1 in necrosis.

Poly(ADP-ribose) polymerase-1 (PARP-1) is an abundant nuclear enzyme of eukaryotic cells that has been implicated in response to DNA injury. PARP-1 detects single-strand DNA breaks induced by a variety of genotoxic insults. A hyperactivation of PARP-1 is believed to play a critical role in tissues

Inhibition of interleukin-1 and tumor necrosis factor-alpha synthesis following treatment of macrophages with the kappa opioid agonist U50, 488H.

Previous reports from this laboratory, and others, have shown that exogenous mu and kappa opioids modulate both cellular and humoral immune responses. Our earlier work has suggested that accessory cells may serve as a target for the direct effects of kappa opioid compounds. In the present study, the

N-(2-hydroxyphenyl)acetamide and its gold nanoparticle conjugation prevent glycerol-induced acute kidney injury by attenuating inflammation and oxidative injury in mice.

The protective activity of N-(2-hydroxyphenyl)acetamide (NA-2) and NA-2-coated gold nanoparticles (NA-2-AuNPs) in glycerol-treated model of acute kidney injury (AKI) in mice was investigated. NA-2 (50 mg/kg) and NA-2-AuNPs (30 mg/kg) were given to the animals for four days followed by 24-h water

Effects of the novel non-steroidal anti-inflammatory compound [N-(2-thiolethyl)-2- {2- [N'- (2,6- dichlorophenyl) amino] phenyl}acetamide on cytokines and apoptosis in ischaemic rat brain.
