A series of N,N'-disubstituted-2-nitroethene-1,1-diamine and N,N'-disubstituted- N''-cyanoguanidine derivatives were prepared and evaluated for in vivo analgesic activity. The blood brain barrier (BBB) VolSurf model was used to predict the BBB permeation profiles of our synthesized compounds. Some compounds show both remarkable analgesic activity and good BBB permeation profiles, and these comp...

Some 1,5-diaryl-3-ethoxycarbonyl-2-methylpyrrole derivatives were obtained by reacting 1-aryl-3-ethoxycarbonylpent-1,4-diones and a suitable aniline derivative or sulfanilamide under Paal-Knorr pyrrole synthesis conditions. The cytotoxicity of the compounds was tested and all compounds, except for compound 2 h, showed a time-dependent increase in cytotoxic activity. Analgesic activities of the ...

BACKGROUND The purpose of this study was to investigate the influence of single or chronic (21 days) administration of the serotonin and noradrenaline reuptake inhibitor, venlafaxine, on the antinociceptive action of the opioid receptor agonist, morphine, in streptozotocin (STZ)-induced hyperalgesia. METHODS The studies were performed on male Wistar rats. Changes in nociceptive thresholds wer...

The present study evaluates the central and peripheral analgesic activity of ethanolic extract of Cananga Odorata Lam [EECO] in experimental animals.Acute toxicity test was done following OECD guidelines. EECO (100mg/kg, 200mg/kg and 400mg/kg b.w. p.o) was evaluated for central and peripheral analgesic activity by the Tail flick method in wistar rats and 0.7%acetic acid induced Writhing test in...

In the present biological studies, several pharmacological investigations were carried out to ascertain analgesic, and antioxidant activity of the ethanol extract of the leaves of Cerbera manghas Linn. (FamilyApocynaceae). The presence of reducing sugars, tannins, steroids, alkaloids, glycosides, and flavonoids were indicated by the phytochemical analysis of the extract. To evaluate analgesic a...

The ring opening of phthalimide derivatives viz N-cyclopentylphthalimide (1a), N-benzylphthalimide (1b), Nprop-2-ynylphthalimide (1c), 1-phthloylamino-3-[4-(2-methoxyphenyl)-piperizin-1-yl]-propane(1d) and 1­ phthloylamino-4-[4-(2-methoxyphenyl)-piperizin-1-yl]-butane (1e) was accomplished using benzylamine in dimethylformamide (DMF) at room temperature to afford the corresponding carboxamides:...

This study examined the effect of trans-dehydrocrotonin (DCTN), a 19-norclerodane diterpene isolated from Croton cajucara Benth (Euphorbiaceae), as analgesic and its effect on the central nervous system (CNS) of rodents using different animal models. The DCTN intraperitoneally exhibited mild analgesic activity on hot-plate test, but exhibited strong antinociceptive activity against acetic acid-...
