Terminoside A (1), a new oleanane-type triterpene was isolated from the acetone fraction of the ethanolic extract of stem bark of Terminalia arjuna. The structure was established as olean-1alpha,3beta,22beta-triol-12-en-28-oic acid-3beta-D-glucopyranoside. On the basis of spectral data and chemical reactions, terminoside A, potently inhibited nitric oxide(More)
Galls of Quercus infectoria Olivier (Fagaceae) possess pleiotropic therapeutic activities, with particular efficacy against inflammatory diseases. The present study was undertaken to evaluate the effect of alcoholic extract of Q. infectoria galls on various in vivo and in vitro experimental models of inflammation. Oral administration of gall extract(More)
AIM OF THE STUDY To investigate the anti-inflammatory and anti-nociceptive activities of the crude ethanolic extract of Adiantum capillus veneris Linn. (Adiantaceae) and its various fractions. MATERIALS AND METHODS The ethanolic extract and its fractions were given at a dose of 200 mg/kg po and 300 mg/kg po for testing their anti-inflammatory activity by(More)
Despite a significant work on thiadiazoles, continuous efforts are still being made to identify novel heterocyclic compounds with potent biological activities. This review may help the medicinal chemists to develop new leads possessing 1,3,4-thiadiazole nucleus with higher efficacy and reduced side effects. This review throws light on the detailed synthetic(More)
Thirteen new 2-pyrazoline derivatives bearing benzenesulfonamide moiety (2a-m) were synthesized by condensing appropriate chalcones with 4-hydrazinonbenzenesulfonamide hydrochloride and tested for anticancer and anti-inflammatory actions. According to the protocol of the National Cancer Institute (NCI) in vitro disease-oriented human cells screening panel(More)
PURPOSE To unmask the vasoconstricting effect of angiotensin II (Ang II) on retinal smooth muscle by studying its interaction with endothelium-derived paracrine substances. This study focused specifically on determining the changes in vascular diameter and the release of endothelial-derived vasodilators, nitric oxide (NO) and prostaglandin (PG) I2, from(More)
ETHNOPHARMACOLOGICAL RELEVANCE Trapa natans L. has a folkloric reputation as nutrient, appetizer and astringent. Its utility as antidiabetic, anticancer, diuretic, aphrodisiac, antidiarrhoeal and in many other maladies is well reported in the literature. Therefore, the present study has been carried out to study the antihyperglycemic effect of root extract(More)
Phytochemical investigation of the aerial parts of Callistemon lanceolatus DC (Myrtaceae) led to the isolation of two new flavones characterized as 5,7-dihydroxy-6,8-dimethyl- 4' -methoxy flavone (1) and 8-(2-hydroxypropan-2-yl)-5-hydroxy-7-methoxy-6-methyl-4'-methoxy flavone (2) along with the seven known phytoconstituents. The structures of new compounds(More)
ETHNOPHARMACOLOGICAL RELEVANCE Leaves of Platanus orientalis Linn. are used in folk medicine as a wound-healer and ophthalmologic agent. Phytol derivatives from the leaves of plane-tree show anti-ulcer activity. Its analgesic and anti-inflammatory effects for knee pain were known to Persian scientists and hakims. MATERIALS AND METHODS The ethanolic(More)
A library of novel bis-heterocycles containing benzoxazolinone based 1,2,3-triazoles has been synthesized using click chemistry approach. The compound 3f exhibited potent selective COX-2 inhibition of 59.48% in comparison to standard drug celecoxib (66.36% inhibition). The compound 3i showed significant (p < 0.001, 50.95%), TNF-α inhibitory activity as(More)
