A series of 4-(methylsulfonyl)aniline derivatives were synthesized in order to obtain new compounds as a potential anti-inflammatory agents with expected selectivity against COX-2 enzyme. In vivo acute anti-inflammatory activity of the final compounds 11-14 was evaluated in rat using an egg-white
Environmental risk assessments show increased attention to the sublethal effects of chemicals on aquatic organisms. The Organization for Economic Cooperation and Development (OECD) established the "Fish, Short-term Toxicity Test on Embryo and Sac-fry Stages" (OECD test 212) to predict lethal
Temporary henna tattoos or pseudotattoos have become increasingly widespread among children and adolescent. A generalized skin reaction, type erythema multiforme-like reaction is unusual, and rarely reported. We describe the case of a 7-year-old boy who reported erythematous papular bull's-eye
In this study, synthesis of nine N-phenylsulfonamide derivatives was designed by starting from aniline, which is the simplest aromatic amine. These compounds were obtained in yields between 69 and 95%. Inhibitory properties of synthesized compounds on carbonic anhydrase I (CA I), CA II isoenzymes,
In rats, 3 days treatment with paracetamol (1 oral dose of 1 g/kg daily) produced a complete protection against the hepatotoxic actions of a further dose of paracetamol as documented by determination of serum enzyme activities (glutamic-oxaloacetic transaminase, (GOT), glutamic-pyruvic transaminase
BACKGROUND
The patient population receiving long-term oxygen therapy has increased with the rising morbidity of COPD. Although high-dose oxygen induces pulmonary edema and interstitial fibrosis, potential lung injury caused by long-term exposure to low-dose oxygen has not been fully analyzed. This
In search for new antiinflammatory agents, a series of 2-(E)-(4-hydroxy-3-methoxybenzylidene)-5-(N-substituted aminomethyl) cyclopentanones was synthesized via Stork reaction, Mannich reaction and amine exchange reaction. All of the fifteen target compounds were characterized by spectral analysis
Sex related differences in drugs metabolizing enzymes was studied using Wistar-rats bearing carrageenan-induced edema. One day after treatment with carrageenan, aminopyrine N-demethylase activity was inhibited in males but not in females. Carrageenan treatment did not alter the activity of aniline
Fish embryo toxicity tests are used to assess the lethal and sublethal effects of environmental chemicals in aquatic organisms. Previously, we used a short-term toxicity test published by the Organization for Economic Co-operation and Development (test no. 212: Fish, Short-term Toxicity Test on
Pesticides are known to transform in the environment, but so far the study of their effects in the environment has concentrated on the parent compounds, thereby neglecting the effects of the degradation products. The embryotoxic, developmental, and teratogenic effects of chloroacetanilide herbicides
A series of 2-bromo-1-hydroxyquinolizinium bromide substituted anilinium salts have been prepared by reaction of 1-acetoxy-2-bromoquinolizinium bromide with an appropriately substituted aniline. The resulting anilinium derivatives exhibited a moderate to high degree of anti-inflammatory activity in
The compound (E)-2-cyano-3-(1H-indol-3-yl)-N-phenylacrylamide (ICMD-01) was designed and developed based on the structures of clinically relevant drugs indomethacin and paracetamol through the molecular hybridization strategy. This derivative was obtained by an amidation reaction between substituted
The anti-inflammatory and analgesic activities of a series of 3-methyl-N-phenyl-1H-pyrazol-5-ylcarboxamides were investigated and compared with flufenamic acid. The compounds were synthesized by condensation of diketopiperazines 2 with the appropriate aniline. The pharmacological tests showed that
Hydroxytriazenes and their derivatives have been studied for the biological and pharmacological applications in the past few years. These compounds possess antibacterial, antifungal, anti-inflammatory, analgesic and wound healing activities. In this study, we report the synthesis of
