Lawsonia inermis (Lythraceae) known as henna is one of the most popular and ancient plants used in cosmetics and hair dying. It is cultivated for its leaves but other parts such as seeds, flowers, stem bark and roots are also used in traditional medicine for millennia. Henna tattoo paste also proved
alpha-Acetylamino naphthalene (1) was reacted with different aromatic aldehydes and with primary or secondary amines to give alpha-aminonaphthylsubstitutedaryl chalkones (2-5) and alpha-(substituted aminoethyl)-amidonaphthalenes (14-25), respectively. These substituted chalkones were treated with
Nuclear factor erythroid 2-related factor 2 (NRF2) is a pleiotropic transcription factor which regulates the constitutive and inducible transcription of a wide array of genes and confers protection against a variety of pathologies. Directly disrupting Kelch-like ECH-associated protein 1 (KEAP1)-NRF2
In the present study, some naphthalene derivatives have been synthesized by incorporating azetidinyl and thiazolidinyl moieties at its alpha- or beta-positions such as alpha-(3-chloro-2-oxo-4-substituted)aryl-1-azetidinyl)naphthalenes 6-10,
Diallyl trisulfide (DATS) is a garlic organosulfide that may have a therapeutic potential in the treatment of some diseases. We sought to determine whether DATS could inhibit naphthalene-induced oxidative injury and the production of inflammatory responses in vitro and in vivo. A549 cells were
The aim of this study was to investigate the possible protective effects of diallyl trisulfide (DATS) against naphthalene-induced oxidative and inflammatory damage in the livers and lungs of mice. Elevated serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels showed
Although inhibition of epidermal growth factor receptor (EGFR)-mediated cell signaling by the EGFR tyrosine kinase inhibitor gefitinib is highly effective against advanced non-small cell lung cancer, this drug might promote severe acute interstitial pneumonia. We previously reported that molecular
To overcome the local gastric toxicity associated with use of common non-steroidal anti-inflammatory drugs (NSAIDs), some aminoalcohol esters of NSAIDs bearing structural resemblance to the aminoalcohol ester class of anticholinergics were specially designed and synthesized. Besides blocking the
BACKGROUND
Nepenthes mirabilis (Lour.) Rafarin (Nepenthaceae) is a carnivorous plant used as a folk medicine in the treatment of jaundice, hepatitis, gastric ulcers, ureteral stones, diarrhea, diabetes, and high blood pressure. Neither the phytochemical content nor biological activities of N.
Two new series of EP(4) antagonists based on naphthalene/quinoline scaffolds have been identified as part of our on-going efforts to develop treatments for inflammatory pain. One series contains an acidic sulfonylurea pharmacophore, whereas the other is a neutral amide. Both series show subnanomolar
OBJECTIVE
This study was undertaken to compare the analgesic activity of antagonists acting at P2X1, P2X7, and P2Y12 receptors and agonists acting at P2Y1, P2Y2, P2Y4, and P2Y6 receptors in neuropathic, acute, and inflammatory pain.
METHODS
The effect of the wide spectrum P2 receptor antagonist
The title compounds were prepared by reaction of beta-acetylamino-naphthalene with different aromatic aldehydes followed by cyclisation with hydrazine hydrate and with different primary or secondary amines (Mannich's reaction), respectively. The structures of new compounds were confirmed by 1H-NMR
BACKGROUND
Furanone and pyrrolone heterocyclic ring system represent important and interesting classes of bioactive compounds. Medicinal chemists use these heterocycyclic moieties as scaffolds in drug design and discovery.
METHODS
A series of 3-arylidene-5-(naphthalene-2-yl)-furan-2(3H)-ones (2a-j)
Highly reactive zinc metal was prepared by electrolysis of a N,N-dimethylformamide (DMF) solution containing naphthalene and a supporting electrolyte in a one-compartment cell fitted with a platinum cathode and a zinc anode. This highly reactive electrogenerated zinc (EGZn/Naph) was used for
