Ingia / Ingia
The terpenoid lactone nimbolide, the structure of which has been unambiguously established, was found to inhibit Plasmodium falciparum in culture with a moderate potency. The EC50 against the parasite line K1 from Thailand was approximately 2.0 microM (0.95 microgram/ml). The EC50 of crude aqueous
Staphylococcus aureus is a leading aetiologic agent of nosocomial- and community-acquired infectious diseases worldwide. The public health concern regarding staphylococcal infections is inflated by the increasing occurrence of multidrug-resistant strains, e.g. multidrug- and meticillin-resistant

The reisolation of nimbolide [1] from Azadirachta indica of Tanzanian origin and the isolation and structure elucidation of a new limonoid, 28-deoxonimbolide [2], from the same plant source are reported. For the first time, unambiguous 1H- and 13C-nmr assignments of compounds 1 and 2 are presented,
We investigated the cytotoxic effects of nimbolide, a limonoid present in leaves and flowers of the neem tree (Azadirachta indica) on human choriocarcinoma (BeWo) cells. Treatment with nimbolide resulted in dose- and time-dependent inhibition of growth of BeWo cells with IC(50) values of 2.01 and
Nimbolide, a limonoid present in leaves of the neem tree (Azadirachta indica), is an anticancer compound against a panel of human cancer cell lines. The rapid process of extraction and purification of the nimbolide from the leaves of neem tree through microwave-assisted extraction (MAE)

Ingia / Ingia
An improved and sensitive High Performance Thin-Layer Chromatography (HPTLC) method has been developed for determination of anticancer compound, nimbolide in different parts of Azadirachta indica and its dosage form. A quick and simple ultrasonication technique was used for the preparation of sample
The present study was conducted to find the cytotoxicity in vitro of nimbolide, limonoids derivative of flowers and leaves from Azadirachta indica (neem tree) on the selected cell lines of cancer (Du-145, PC-3, A-549) and normal fibroblast cell lines (NIH3T3, CCD-18Co) using MTT assay. The cells
Nimbolide, a triterpenoid extracted from the flowers of the neem tree (Azadirachta indica), was found to have antiproliferative activity against some cancer cell lines. Treatment of cells with 0.5-5.0 microm concentrations of nimbolide resulted in moderate to very strong growth inhibition in U937,
The present study was designed to investigate the in-vitro morphological assessment of apoptotic effect caused by nimbolide on the selected cancer cell lines (DU-145, PC-3, A-549) and normal cell lines (NIH3T3, CCD-18Co). The cells were grown in 6 well tissue culture plates after treatment

Two new tirucallane triterpenoids, 24,25-epoxy-3 β-hydroxy-20-oxo-7-tirucallene (1) and 22,23;24,25-diepoxy-3 β-hydroxy-7-tirucallene (2), and a new tetranortriterpenoid, 4 α-hydroperoxy-6- O-acetylnimbandiol (3), along with eight known compounds, were isolated from the branches and leaves of

Quinone reductase inducers in Azadirachta indica A. Juss flowers, and their mechanisms of action.

Ingia / Ingia
We have previously shown that the flowers of neem tree (Azadirachta indica A. Juss, family Meliaceae), Thai variety, strongly induced the activity of glutathione S-transferase (GST) while resulting in a significant reduction in the activities of some cytochrome P(450)-dependent monooxygenases in rat
Nimbolide, a natural triterpenoid present in the edible parts of the neem tree ( Azadirachta indica), was found to be growth-inhibitory in human colon carcinoma HT-29 cells. Nimbolide treatment of cells at 2.5 - 10 microM resulted in moderate to very strong growth inhibition. Flow cytometric
We evaluated the protective effects of subfractions of the ethyl acetate fraction (EAF) and the methanolic fraction (MF) from the crude ethanolic extract (CEE) of Azadirachta indica A. Juss (neem) leaves against various free radicals and hydrogen peroxide (H2O2)-induced oxidative damage to red blood
Seven coumarin derivatives (imperatorin, heraclenin, xanthotoxin, marmesin, chelepin, oxypeucedanin, esculin) and a furan derivative (nimbolide) were screened on 6 Ames tester strains (TA92, TA94, TA97, TA98, TA100, TA102). The eight compounds are chemicals isolated from three Nigerian medicinal

Nimbolide B and nimbic acid B, phytotoxic substances in neem leaves with allelopathic activity.

Ingia / Ingia
Neem (Azadirachta indica) has been widely used as a traditional medicine and several bioactive compounds have been isolated from this species, but to date no potent allelopathic active substance has been reported. Therefore, we investigated possible allelopathic property and phytotoxic substances
