The present study reports on the antifilarial activity of a marine sponge Haliclona exigua (phylum Porifera). The crude methanol extract and n-butanol-soluble fraction killed adult Brugia malayi at 31.25-microg/ml concentration (both in motility and 3-(4,5 dimethylthiazol-2-yl)-2,5 diphenyl tetrazolium bromide assay) while the chloroform fraction was lethal(More)
The present study is aimed to evaluate antifilarial activity of Xylocarpus granatum (fruit from Andaman) against human lymphatic filarial parasite Brugia malayi in vivo. The in vitro antifilarial activity has already been reported earlier for this mangrove plant which has traditionally been used against several ailments. Aqueous ethanolic crude extract,(More)
This review covers about 40 species of the genus Sinularia, in which many compounds with novel chemical structures have been isolated, characterised and bioassayed for various activities since the beginning of marine chemistry until now. The bioactivities of the metabolites have been reported in the tables wherever found in the literature.
The natural product lansimide 2 is a 1:1 mixture of two different cyclic amides, C18H17NO2.C18H19NO3. The mixture crystallizes as a molecular pair in the centrosymmetric space group P21/n. M(r) = 576.69, monoclinic, a = 20.151 (2), b = 6.2984 (4), c = 24.051 (2) A, beta = 104.339 (8) degrees, V = 2957.4 A3, Z = 4, Dx = 1.30 g cm-3, Cu K alpha, lambda =(More)
BACKGROUND This study was aimed to investigate the pregnancy interceptive activity of the stem bark of Dysoxylum binectariferum Hook. f. administered during the pre- and peri-implantation periods and immediately after implantation by oral route in adult female Sprague-Dawley rats. STUDY DESIGN Ethanolic extract and its fractions were administered to(More)
Interest in alternative medicine and plant-derived medications that affect the "mind" is growing rapidly since last two decades. The aim of the present study was to investigate the effects of ethanolic extract of flower of Plumeria rubra (PR) along with its fractions in the elevated plus-maze (EPM) model of anxiety. The P. rubra extract or its fractions was(More)
We developed a common feature pharmacophore model using known antiadipogenic compounds (CFPMA). We identified rohitukine, a reported chromone anticancer alkaloid as a potential hit through in silico mapping of the in-house natural product library on CFPMA. Studies were designed to assess the antiadipogenic potential of rohitukine. Rohitukine was isolated(More)
Hexane extract of the seeds of Nigella sativa L. prevented pregnancy in Sprague-Dawley rats treated orally at 2 g/kg daily dose on days 1-10 post-coitum. Significant antifertility activity was also observed in its column fractions and subfractions. At contraceptive dose, the active hexane extract exhibited only mild uterotrophic activity comparable almost(More)
