Prostate cancer is one of the most diagnosed forms of cancer among men in western regions. Many traditional applications or phytotherapeutic concepts propose to inhibit the proliferation of prostate cancer cells. In order to detect influences of plant or fungal extracts and derived
Multi-drug resistance (MDR) remains a major impediment in cancer therapy. A major goal for scientists is to discover more effective compounds that are able to circumvent MDR and simultaneously have minimal adverse side effects.
In the present study, we aim to determine the
In the course of our continuing search for novel cancer chemo-preventive agents from natural sources, we have carried out a primary screening in vitro assay of the compounds isolated from Aglaia odorata. Consequently, aminopyrrolidine-diamides, odorine and odorinol, were obtained as active
Bioactivity-guided fractionation of extracts of Aglaia loheri Blanco (Meliaceae) yielded a cytotoxic isolate, termed Maldi 531.2[M + H]+. This phenolic ester was further investigated for its in vitro cytotoxicity toward human CCRF-CEM leukemia cells and their multi-drug resistant (MDR)
During the past few years, a group of cyclopenta[b]benzofurans from the plant genus Aglaia has received broad scientific attention as interesting natural product lead compounds with potential anticancer and insecticidal activities. Since the first cyclopenta[b]benzofuran derivative, rocaglamide,
Plants in the Meliaceae family are known to possess interesting biological activities, such as antimalaral, antihypertensive and antitumour activities. Previously, our group reported the plant-derived compound cycloart-24-ene-26-ol-3-one isolated from the hexane extracts of Aglaia exima leaves,
Multidrug resistance (MDR) is a major contributory factor in the failure of chemotherapy. Concrete interpretation of P-glycoprotein (P-gp) substrate specificity, whether a substance is a substrate or an inhibitor, represents an important feature of a compound's pharmaceutical profiling in drug
HPLC-guided separation of twigs of Aglaia odorata led to the isolation of eight lignans, including two new ones, 3'-methoxy-N-demethylrocaglamide (1) and 4'-O-demethyl-deacetylaglaxiflorin A (2). Compound 1 showed excellent cytotoxicity against three human cancer cell lines, HeLa, SGC-7901 gastric
A new dammarane triterpene, 3-acetoxy aglinin C (1), and a new aglain, 10-oxo-aglaxiflorin D (2), along with five known compounds, 3-7, were isolated from the leaves of Aglaia odorata using chromatographic methods. The structures of 1 and 2 were determined on the basis of spectroscopic analyses.
One new norsesquiterpene (1), and four new sesquiterpenes (2 - 5), along with four known ones, were isolated from the twigs of Aglaia odorata var. microphyllina C. DC. Monogr. Their structures were established based on spectroscopic methods including HR-ESI-MS, 1D, and 2D NMR. Compounds 1, 3, and 6
Six new triterpenoids (1-6), along with 10 known compounds, were isolated from the stems of Aglaia abbreviata. The structures of 1-6 were elucidated on the basis of their spectroscopic data. Compounds 1-6 were evaluated for their cytotoxic activities against a small panel of human tumor cell lines.
A seco-apotirucallane-type triterpenoid, namely angustifolianin (1), along with three dammarane-type triterpenoids, (20S, 24S)-epoxy-dammarane-3β,25-diol (2), 3-epi-cabraleahydroxylactone (3), and cabralealactone (4), were isolated from the stem bark of
A total of five 1H-cyclopenta[b]benzofuran lignans (1-5) isolated from the stems of Aglaia elliptica B1. (Meliaceae) inhibited the growth of human cancer cells in culture. Of particular note, the IC50 values observed with 1 (methyl rocaglate), 2 (4'-demethoxy-3',4'-methylenedioxy-methyl rocaglate)
Three new inositol angelate compounds (1-3) and two new tirucallane-type alkaloids (4 and 5) were isolated from the Amoora dasyclada, and their structures were established mainly by means of combination of 1D and 2D nuclear magnetic resonance and HR-ESI-MS. Based on
